WARNING

Using computer procedures involves knowing the operative system. The Geomatics products were created for 32bit Windows 2000, Windows XP and Windows Vista operative systems. The operative system is loaded on turning on the computer and works as interface between the program and the computer. The operative system is not provided together with Geomatics Suite, so it must be already present in the computer. Knowing the operative system base principles is necessary for a full comprehension of this guide and for a correct use of the program.

This is not a guide to operative systems, for which you should refer to Windows 2000/XP/Vista guides or to the numerous publications on the matter. This guide does not intend to give instructions concerning the use of topographic instruments and of computer peripherals. This guide is by no means a course of topography.

ProSt

13

ProSt By ProSt it is possible to design roads, hydraulic works and any other linear work; the project includes the geometry annotation performed according to topographic surveys or existing maps, the management of terrain and project longitudinal profiles and the length of cross sections with volume calculation. ProSt Premium includes a set of tools to solve easily and precisely all the problems concerning the planning of road intersections

Survey and cartography

According to a topographic survey or an existing map, ProSt can perform the modelling of the terrain on which to base the whole design and the extraction of terrain sections and profiles.

Plano-altimetric design

The design of a horizontal alignment can be performed in the graphic window and allows the definition of

any kind of alignment. Terrain profiles and sections are extracted from survey data or from the maps loaded; altimetric design is carried out by inserting grade lines and vertical curves.

Policy check

Policy check supports the user during the phases of insertion and modification of the plano-altimetric alignment, by generating the corresponding speed diagram.

Cross sections and typical sections

By parametric design it is possible to check a project and its parameters. Cross sections are completed by inserting the corresponding typical section , but it is always possible to modify the parameters of the single section. A specific editor allows to create and customize the typical sections by using a wide library of parametric objects which can be extended by the user.

Volume and quantity calculation

Survey and cartography

Survey properties

A set of data and parameters concerning not the project but the active sub-project are grouped in this section. This means that inside a single project there can be more sub-projects, each one with general data apart from the others. See Subprojects management.

The management of the survey properties can be activated through one of the following methods:

Toolbar Topography

Menu Survey > Survey properties

Command line: DDSPROP

ProSt

31

Drawing Filters tab

Through this page you can check the display of all active sub-project topographic entities: if check box is active, then the corresponding entity will be visible, if not, it will be invisible.

Through Lock topographic points option it is possible to block subproject survey points in order to avoid possible wrong selections that could cause a shifting on points position or, in the worst of the

cases, their total cancellation.

The drawing filters act on the entity visibility apart from the layer which the entity belongs to; this way, it is possible to decide, for example, whether to make all survey points invisible even if they belong to different layers. Without this option it would have been necessary to freeze all layers containing points

risking to freeze also the other entities.

Even if an entity is set as visible, when the layer which the entity belongs to is freezed or disabled the entity is not visualized .

By selecting the item All subprojects you can assign all the current subproject settings to all the other subprojects. In this way, for example, it is possible to make invisible the points of all subprojects using only one command without having to activate each subproject and for each of them make all points invisible. By selecting the item Current subproject all settings are assigned only to the current subproject.

toolbar:

Table standard editing commands The first six icons activate each table standard editing commands:

Cut: cuts selected cells;

Copy: copies selected cells;

Paste: pastes the cells previously copied or cut;

Change rows: modifies automatically a group of cells belonging to a table column. The change can consist in setting the same value to all the cells, in cancelling the content of all the cells or also in increasing the cells value.

Find and replace: allows to find and if necessary to replace, all the recurrences of a certain value in

The command Rows color by code contained in some tables, applies the same background colour to the rows containing data with the same code:

Display commands

By or command it is possible to zoom on the graphic, so that the resulting view will be centered on the measure or on the point selected.

Coordinates

By topographic coordinates we mean the set of topographic points representing a survey. These coordinates are very important, because they are the connection between Topography and Road design:

in fact, through the coordinates it is possible to obtain a road longitudinal profile and cross sections. Besides, they are a base concept both for cadastral management and for the management of

mathematical models. They are therefore of the utmost importance for the management of any topographic work.

The tool does not admit points with the same name; for this reason different checks are performed, both on inserting / importing the data and on modifying them.

Check point name

The tool does not admit points with the same name. The check starts during the insertion/modification and importation of the survey points.

On inserting and modifying the data, the tool prevents a name already assigned to a point from being

assigned to another point.

During the importation the tool verifies, for each point imported, whether another point exists with the

same name; in case another point is found, the tool displays both the coordinates and allows to carry out one of the following operations: calculate the average between the coordinates, keep the existing point, replace the existing point with the new point, rename the new point.

ProSt

39

Replace: Replaces the coordinates of the existing point with the coordinates of the new point.

Replace all: Replaces the coordinates of all the existing points with the coordinates of the new points.

Keep existing: Keeps the coordinates of the existing point

Keep all: Keeps the coordinates of all the existing points

Rename from: Renames the new point with the name indicated in the input field. If the option Add suffix is active, a suffix will be added to the point name.

Rename all: Renames all the points starting from the name indicated in the input field. If the option Add suffix is active, a suffix will be added to the point name.

Average: Assigns to the existing point the average calculated between coordinates

Average all: Assigns to all the existing points the average calculated between coordinates.

How to erase a survey point from graphic CAD In order to erase a survey point directly from graphic CAD window, it is sufficient to use Erase command,

which is used to erase any kind of entity.

How to modify a survey point If you want to change the position of a survey point, it is possible to use all the edit functions provided by the graphic CAD (move, copy, rotate, etc.).

A faster means to move survey points is to use Grips.

Survey point grips are at least two:

1. the first is situated in the centre of the symbol representing the point and is necessary to perform the shift and the rotation of this point;

2. In case the point labels style is the default style, a grip is displayed on the first text associated to the point; otherwise, a grip is displayed on any label associated to the point. Grips are used to

shift texts or make them invisible.

Clicking on the first grip, the usual grip options appear on command line, thus allowing to change the

position of the point. To rotate the point symbol choose the option Rotate symbol and then give the new symbol direction.

Command line: DDEDITPNT

It is sufficient to select by mouse a survey point on the screen so that all the data concerning this point

appear in this dialog box where it is of course possible to modify them. It is possible to modify cartesian coordinates, elevation and second elevation. Other data are available in Data tab:

In this tab it is possible to modify name, code or description of the point selected. In order to make this

changes operative, it is necessary to click on Apply button.

Interpolation of a point elevation By this command you can interpolate a point elevation by using two points, a line, three points, a triangle or a whole triangle digital model.

The command can be activated by one of the modes listed below:

Toolbar Survey

Menu Survey > Topographic point > Interpolation of elevation

Command line: INTELEV

On CAD command line, the following questions appear:

Elevation Interpolation by 2 points/Line/3 points/3D Polyline/Triangle/DTM <2> :

ProSt

Acquisition of topographic coordinates from ASCII file

The acquisition of topographic coordinates from ASCII file is useful whenever you have a set of coordinates on text file and you want to import them inside the tool without having to insert all data manually.

The acquisition of survey points requires that all data inside ASCII file are organized according to the following instructions:

each line of the file must indicate survey point data.

each survey point data must be separated by a particular symbol or must be set up in fixed

columns.

In order to activate the import procedure it is necessary to select the item Import/Export from File

menu and then ASCII In, you can also give ASCIIIN command.

Menu File : Import/Export > ASCII IN

Command line: ASCIIIN

A dialog box appears, where you must indicate the name of the ASCII file to be loaded and the folder where the file is saved; select the option Topographic coordinates.

Pressing Next button you go on with the definition of import parameters and a second dialog box appears, asking to indicate the data contained in the file and the order according to which they have

been saved: select the kind of data in the left list box and then, by pressing > button, they will be shifted into the right box. In this box, data order must correspond to data order in text file rows.

The third dialog box allows to decide whether the data are separated by such a character as a comma, etc. (Delimited) or divided into columns (fixed width).

If the data are separated by a character, the tool asks you to indicate the character that separates them; if, on the contrary, data are divided into columns, you will have to indicate the widths of the columns so

that the tool can find out the data. For each column, specify the width occupied by the text.

At the last dialog box the tool is ready to read the data and asks you whether these data must be added to the already present ones or the already existing data have to be canceled.

In the dialog box select the node Topographic coordinates and choose the kind of printing to be created.

Constraints

Constraints are tridimensional lines which connect survey points. They can be used in order to:

Define constraints for the construction of a triangle mathematical model. The presence of these lines forces triangulation procedure to build the triangles according to what has been set by the user, so that the survey mathematical model resembles the real model as much as possible;

Define a line (not a triangle) mathematical model, to be used, usually in road planning, to survey cross-sections. For some works, (e.g. betterment of existing roads) the line mathematical model is

the easiest solution and offers the most accurate results.

There are two kinds of constraint lines:

Break lines (discontinuity);

Boundary lines;

ProSt

63

If, after the next triangulation, you do not obtain the results needed, because of the triangles overimposed on one another or created outside the boundary, it is possible to perform an automatic check on the correctness of the input constraints. See Check on constraints.

It is possible to transform drawing lines into constraints and vice versa. See Transformation of drawing entities into topographic entities.

The time needed to insert the constraints among the points can be reduced by drawing polylines passing by the points to connect; a specific command allows to transform these polylines into constraints passing exacltly through the points. SeeGeneration of constraints from polylines.

Constraints can be created automatically using surveyed points codes. See Automatic drawing from codes.

Constraints can be imported from DXF file of AutoCad and they can also be exported on DXF file. See Import and export of constraints from DXF file.

An utility option is also available which allows to create survey points directly from constraints extremities. See Creation of coordinates from constraint line extremes.

Break lines

Break lines represent so called discontinuity lines, that are lines which refer to some particular characteristic of the zone surveyed. They can be input for example to represent the basis and the top of a slope: in this case the procedure for the creation of triangles will build some triangle strata inside the two polylines indicated, so the model and the results of the elaboration obtained hereafter will be precise.

More complex is the case of a vertical wall, since the tool is unable to manage those survey points which coincide from a planimetric point of view. For this reason, it will be necessary to move slightly the points

representing the top of the wall and then to insert some break lines connecting all the top points of the wall and all the basis points of the wall.

In order to input break lines, it is necessary to operate using one of the following methods:

DTM Toolbar:

Menu D.T.M. > Constraints > Breaklines

Command line: CONSTRAINTS

On CAD command line the following questions appear:

Constraints break Lines/Boundaries/<L>: L

First point :

Next point :

The points indicated must have an elevation. Otherwise the tool refuses their selection.

Note. when you create break lines, situations when two constraints intersecate should never be created otherwise the created model will result wrong. See Check on Constraints.

Note. When the tool asks you to indicate constraint points, it is necessary to operate in one of the following ways:

indicate by mouse the point needed ;

answer the question by digiting the name of the point needed: the tool will search inside the file the point indicated and, if it finds this point, it will proceed to the following question.

You might have to change the typology of a constraint, turning a boundary line into a break line or vice versa. There is a specific command which allows to make this change:

ProSt

64

Boundary lines

Boundary lines are used to define the area inside and/or outside which the triangles have to be built.

They must enclose the area, so the last constraint must be connected with the first. Boundary lines are different from Break lines in that they have a perpendicular segment, representing the direction opposite to which the triangles have to be built. In order to set the size of the perpendicular segment see Miscellaneous page in Project properties.

It is possible to set a contour area inside which the program will build the triangles and exclude from it some inner zones that are not important for the building of the model: it is sufficient to input boundary lines with the perpendicular segment situated at the opposite of the area where the triangles will be built.

In order to input boundary lines it is necessary to operate in one of the following ways:

DTM Toolbar:

Menu D.T.M. > Constraints > Boundary

Command line: CONSTRAINTS


Constraints break Lines/Boundaries/<L>: B First point : Next point :

The points indicated must have an elevation, otherwise the tool refuses their selection.

Note. When you create a boundary, it is necessary that the boundary created is closed and that all boundary lines have the perpendicular segment always situated at the opposite of the area where the

triangles will be built. See Check on constraints.

Triangles

The management of a terrain mathematical model allows to create triangles, in order to approximate mathematically the real terrain model, so that it is possible to interpolate terrain elevations even where points have not been observed. The definition of a mathematical model can be performed in one of the following ways:

automatic mode: the tool builds automatically the triangles, respecting possible break lines and boundaries (see Constraints).

Triangles colour can vary according to barycentre elevation: the user can decide the range of colours to use and the intervals to associate to each colour. A colour can be set on creating the triangles but also later.

ProSt

The tool gives the possibility to transform drawing 3DFaces into triangles and vice versa. See 3DFace-triangles transformation.

Triangles can be imported from AutoCad DXF file and can also be exported, again on DXF file. How to import/export triangles from DXF file

Automatic triangulation

The tool can build the triangles automatically in two ways :

Free triangulation : the tool generates the triangles without taking into consideration possible boundary or break lines;

Constrained triangulation: if boundary or break lines have been set, the tool will follow this information during the generation of the triangles which will not exceed the boundary set and will not

cross a break line (see Constraints).

This procedure can be activated through one of the following modes:

Toolbar DTM:

Menu D.T.M. > Triangulation > Automatic

Allotment: triangles are created inside an allotment.

Entities to triangulate: In case of Free and Constrained triangulation it is possible to decide on what

entities to carry out the triangulation.

All: all the points and break lines contained in the survey subproject are used.

Select by window: After pressing Apply button the tool will prompt the creation of a check window in the graphic CAD; the model will be created by using only the points and the break lines selected.

Select by polyline: After pressing Apply button the tool will ask to indicate the polyline

delimiting the area to triangulate; the model will be created by using only points and break lines

inside the polyline. The break lines partially included in the polyline are automatically broken. If the option

Delete previous triangles is active, the tool, before performing the triangulation, will delete automatically the possible triangles inside the polyline.

Remove triangles with side length over: E' possibile impostare la massima lunghezza possibile per i lati del triangolo. I triangoli con un lato superiore alla lunghezza massima non verranno disegnati.

Break constraints with length over: The constraints with lenght over the value set are subdivided into smaller parts.

Check data. If the option is active, a data check is carried out during triangulation; it consists in verifying the presence of the following error situations:

Survey points with coincident planimetric coordinates: if the tool is confronted with such a situation, the double point will not be used to perform the triangulation;

Intersection of constraints: in this case the tool informs you of the error and interrupts the

elaboration;

Overlapped constraint lines: one of the two lines will not be used to perform the triangulation;

Zero-length constraint: the constraint is erased;

Point with no distance from the constraint: the situation is pointed out and the elaboration is interrupted;

Delete previous triangles. If the option is active, the previous triangles are deleted before performing triangulation.

Symbols. It is possible to choose one of the three symbols listed below to represent the triangle:

Lines: the three bisecting lines of the triangles are created;

Number: triangle number is drawn. This option is particularly useful when volume calculation printout is added to drawings; by this way, it is possible to compare printout data with drawing ones.

How to erase or modify triangles

If you want to modify the position of a triangle, you can use all the edit functions offered by Graphic CAD (move, copy, rotate, etc.).

It is possible to modify easily the shape of a triangle by Grips (see Grips). There are four grips per triangle: one for each vertex and one grip along the first side of the triangle. The three grips which are on

the vertexes are used to change the position of each vertex, that is the shape of the triangle. On the contrary, the fourth grip is used to move the triangle.

Contour lines

On the basis of mathematical model triangles, it is possible to obtain contour lines through the intersection between horizontal planes (at different elevations) and the model itself. It is possible to generate two kinds of contour lines:

Linear contour lines : more adherent to the triangle mathematical model, they however do not

grant an appreciable aesthetic effect;

B-Spline contour lines: more rounded and nice to see than linear contour lines, even if less accurate;

The colour of contour lines can vary according to the elevation assumed by the curves: the user can choose the range of colours to use and the intervals to be associated to each colour.

Colour setting can be performed on creating the curves but also later.

Contour lines can be quoted either automatically, during their creation, or manually

The tension on contour line vertexes can be set automatically on creating the contour lines, but later it

can also be modified manually. So it is possible to set a specific tension on a particular contour line and also to set a specific tension on a single vertex of a contour line.

It is possible to transform drawing polylines or contour lines with no elevation (2D) into contour lines with

an elevation.

ProSt

73

It is possible to transform drawing polylines into contour lines and vice versa.

Contour lines can be imported from DXF file of AutoCad and also be exported on DXF file.

Creation of contour lines

The procedure that creates contour lines can be activated as follows:

Toolbar DTM

Menu D.T.M. > Contour lines > Contour lines

Command line: CONTOURS

Dialog box is subdivided into three pages:

Countour lines

Subproject. Select the subproject where the triangulation has to be performed.

Contour line intervals. The tool is able to generate three kinds of lines which can differ as far as the layer they belong to and therefore in colour and linetype; you are asked to indicate the equidistance between Normal contours as well as the equidistance of Main contours (i.e. which will be quoted

automatically) : this value must be a multiple of the normal contours equidistance. The other kind of contours is the Auxiliary contours, which will be drawn among normal lines: its value must therefore be

a submultiple of normal contours equidistance.Moreover, the tool displays the minimum and maximum elevation found in the triangle digital model.

ProSt

74

Contour lines can be created by the user also on single intervals which can be defined by specifying Min elevation and Max elevation.

Type of curves. The curves the tool can generate are of two kinds:

Linear: segments obtained from the intersection between triangles and planes at different

elevations.

B-Spline: from the points of intersection between the planes and the triangles, the tool performs a B-spline interpolation, so it can generate rounded-off, better looking curves. If you choose B-spline option, the tool allows to set two other parameters:

Vertexes tension: The tension regulates the side friction factor of the contour line compared to the points of interpolation; the greater the tension, the nearer the curve will be to the points that determined it. It is possible to regulate the tension by Automatic or Manual

mode. With the first option the tool calculates the tension automatically, according to the triangle slope; with a high vertical slope the curve tension will be bigger than the one calculated on less sloped triangles, creating tighter and more linear contour lines on the leaning sides and more rounded off on the triangles in plane areas.

Step: it is the length of the hatches that constitute the b-spline: the shorter the hatches, the more the curve will be rounded. It is better to set values from 0.5 to 5.

Labels

Draw labels. If this option is active, contour line elevation labels are inserted on the bases of the

parameters set in the other fields of the window.

Labels on fixed step: allows to obtain the label at a fixed step along the contour line.

Label distance. Distance between two consecutives labels along the contour line.

Introducing parametric design

Parametric design introduces a new method for defining axes properties in road design.

For each axis a set of properties can be defined, such as typical section, roadway width, transversal slopes, sideslope slopes and, in broad terms, any section property, by station or by section.

In this way for each axis it is possible to define different typical sections and the segments where to use them, so as to simplify the design of roads presenting section changes, as for example in case of

roadways with viaducts and tunnels.

Besides, this system for defining properties by segment allows to define, quickly and precisely, stop areas along the alignment, transversal slopes in particular segments, features of typical elements along the alignment, etc.

This information is reported, both graphically, by a specific diagram, and analytically, by some specific tables.

This design methodology offers two main advantages: the first is a precise and accurate definition of the

axis features, the second is a faster generation of results (Sections, Project planimetry, Road 3D model) because, in case a modification is made, it is not necessary to reinsert all data a second time, but it is sufficient to perform the final elaboration again.

Axis geometric properties

By the window of axis geometric properties it is possible to display, insert and modify all the parameters necessary to generate sections, project planimetry and road final model.

By this window it is possible to define, for each axis, what typical sections to use and the segments in

which they are defined. This allows to define, quickly and precisely, the areas inside the axis where section changes occur (ex. viaducts, tunnels, sections presenting walls, etc,).

It is also possible to define the properties of each typical section in every segment of the alignment,

simply by setting for each station or section the value to be associated to a property of the typical section (ex. roadway width, roadway slope, sideslope slope, etc.)

The window of axis geometric properties can be activated as follows:

Parametric design window display mode The window has two display modes: an extended one and a reduced one. The reduced display shows the following toolbar:

In order to pass from a display mode to the other, use Collapse and Expand commands, on the top right corner of the window.

By Lock command the Parametric design is automatically positioned below the tool window and at

any moment it is possible to activate Unlock command to allow the free positioning of the window.

Toolbar of Parametric Design window In the upper part of the window some checks are available:

Active subproject: Allows to navigate quickly among the axes and choose the one to be made active, i.e. the one whose features have to be displayed;

Warning. The window of parametric design always works on the current axis subproject, so, if we change the current axis subproject from the main window and activate the window of parametric design, the tool will automatically display the data of the new current subproject, updating also all the graphic windows according to the display scheme set. Therefore, if we change the axis subproject from the window of parametric design we will automatically update the active axis subproject.

General: By this button it is possible to activate the window setting the properties of the

active axis;

Display: It is possible to choose the module to display by selecting the

Functions of window display and automatic positioning

The window of parametric design contains a set of functions allowing to position itself automatically and

pilot the display of the other windows in the graphic cad; thanks to such functions, this window can be used as a control panel of the axes as well as of the program itself.

These buttons allow to set the main graphic window that have to displayed

Horizontal aligment elements

Horizontal aligment elements page in parametric design displays in the upper part the policy and the kind of road set in project properties. For any element listed the software carries out in real time the policy

check. If the axis contains element out of policy the symbol will appear near the page title.

The page of horizontal alignments elements reports a sequence of the various elements that make up the

alignment as well as their state: linked or unlinked . The axis horizontal elements must be linked

to each other. If unlinked elements are found, it is necessary to sort the alignment elements. If unlinked elements still remain even once this operation has been performed, it is necessary to check each element directly in the graphic window, to make sure that its extremes are linked to the previous and/or next element.

Moreover, the tool specifies either an element respects the policy set or not ; properties column reports minimum and maximum parameters required for the element and the current value. By clicking

on Policy column it is possible to gain direct access to the window of policy check and in particular to the check of the element selected.

Typical sections tab

In typical sections page it is possible to define the typical sections to insert along the axis and the segments in which they are defined.

It is possible to define both the sections to be used to generate project planimetry and the simplified

sections for model generation and sight check.

The typical sections used in a project are automatically included in the project file itself. In this way the project can be completed by any user on any computer without having to copy manually the typical

sections library files.

Typologies of axis typical sections

The tool provides for the use of two different kinds of typical sections that can be defined for each axis:

Project typical sections and Typical sections for sight diagram.

Project typical sections are used to generate sections, project planimetry and road model from typical sections, while the sight ones are used to generate the model and to verify sight distances.

Throw the pull-down menu is possible to select the intervals to modify: planimetry intervals or sight

intervals.

Display typical sections and their properties

The typical sections defined for axis are displayed in the table on the left of typical sections page, and on the row containing the name of the typical section its different intervals are displayed in the diagram on

the right of the page.

The intervals at which typical sections have been assigned are represented with horizontal bars, reporting in their centre the name of the typical section and on their extremes the station , or the start and final

section of the interval. Such intervals can be modified directly by the diagram (For interval modification

methods see Modify interval). It is possible to import the intervals from ASCII format files by button.

The tool highlights in red the areas in which no typical sections have been defined, so no project sections are supposed to be inserted and no project planimetry is going to be generated.Moreover, the intersection zones situated along the axis are highlighted in light blue, while main points (start,

ProSt

85

intersection and end) are indicated with vertical grey lines; at the bottom the name is displayed, of the axis with which the intersection is performed.

In the diagram it is possible to perform some zooms both by the mouse central wheel and by zooming on the window. To zoom on the window, indicate the window upper left corner, pressing the mouse left button and, keeping the mouse left button pressed, indicate the window lower right corner, then release

the mouse.

To perform the diagram zoom all, operate as with the zoom on window but indicating first the lower right corner and then the upper left corner. Besides, by the mouse right button it is possible to carry out the diagram dynamic pan.

The cursor of the typical sections diagram is dynamically linked to planimetry and profile windows , so each time it moves, its position is automatically updated and displayed both in planimetry and in profile.

By displaying more windows at the same time, among which the cross sections window, moving around

along the typical sections bar in the parametric design, the preview of the cross section is updated; it is possible to indicate by mouse a station in the parametric design and keep it fixed by Ctrl+Tab command on keyboard, to modify the corresponding cross section.

Diagram scroll button activates the updating of typical sections display according to the cursor moving in the graphic window of planimetry, profile or Real Time Design.

The button Zoom on position activates the dynamic link between the visualization in Typical Sections page and the active graphic windows; by moving the cursor inside the diagram , it is possible to obtain an updating of the view in the planimetry, profile and Real Time Design graphic windows

Such commands can be active also simultaneously, allowing to move the pointer in the patrametric design, and have the graphic window always updated, and vice versa. This is particularly useful for long alignments, since it gives a complete and quick control over the typical sections intervals.

At the bottom, on the right, the station value of the pointer position is displayed.

It is possible to display the data table referred to the typical sections by button. The table summarizes the data concerning the intervals at which sections are applied, and it is possible to modify the values in the table. The intervals displaying a breakline are highlighted in red.

button activates in the table the display of all typical sections data, not only of the typical section selected.

Insert, remove, change and modify typical sections

In typical sections page it is possible to insert, delete, replace and modify directly axis typical sections. The following buttons allow to manage typical section modification functions:

Add typical section: By this button it is possible to assign a typical section to the axis. The

typical section is inserted in the typology of typical sections which is active (Project or Sight

diagram) with an interval which is equal to the axis whole length.

Remove typical section: By this button it is possible to remove the typical section selected.

ProSt

86

Modify typical section: By this button it is possible to open the typical section in typical section

builder module and modify its properties and features.

Export typical sections: Since the typical sections used in the different axes of a project are included automatically in the project file, this button allows to export the file of a typical section included in the project file and make it usable by other projects.

Moreover, in case the axis contains more typical sections, it is possible to define creation order by using

and buttons; the first section in the table is generated first, then comes the second, and then all the others.

Insert, remove, modify intervals

After inserting the typical section it is possible to define the axis intervals (segments) where it must be used. The tool provides for a set of commands for interval management, both of typical sections and of

axis variables.

When a new typical section is inserted, a first interval is automatically added, which is equal to the length

of the whole axis. To add further intervals it is sufficient to press button; the following dialog box will be displayed:

By this window it is possible to define the station, or the interval start and end section. Type field indicates whether the value of the start or end station is a numeric value or it is linked to a section. In case the type is Value, in Station field it is possible to insert the station number, while in case the type

is From section in Section field it is possible to insert the section number or name or, by button it

is possible to select the section from the window of sections list.

The values of the interval start and end stations can also be selected directly from the graphic window,

by I button. In case the type is Value the station is calculated from the projection of the point indicated on axis, while in case it is From Section the tool will select the nearest section to the point indicated.

The option Allow the modification in the diagram allows to modify the values of the stations which are not linked to the sections directly in the diagram window; this option can be deactivated so as to avoid the accidental modification of the intervals in the diagram window;

Note: station values linked to a section cannot be modified directly in the diagram.

Intervals can be modified directly by the diagram window or by the window of interval data.

ProSt

87

By the diagram window it is possible to modify, if the interval is not linked to sections, the interval start and end station. To modify an interval by the diagram window it is necessary to position in the interval start or end point and, when the cursor changes its shape becoming a double arrow, press the mouse left button and drag the interval to the station desired.

To modify an interval using the interval data window click twice in the interval to be modified or press

button.

The tool provides for other functions to modify typical section and axis variable intervals, which are the following:

Divide interval: By this function it is possible to divide the interval selected into two parts.

Join interval with the next one: By this function it is possible to join an interval selected with

the following one.

Remove interval:By this function it is possible to remove the interval selected. In case of

typical sections it is not possible to remove the last interval. If you want to remove it, it is necessary

to remove the typical section.

Intersections (ProSt - Premium)

Intersections page allows to manage every kind of intersection in a project: AT-grade intersections, Roundabout intersections, lane entry/exit and lanes division.The window allows the insertion and management of intersections, the modification of parameters and policy check.

The window is subdivided into three main blocks:

Intersections list: the left side reports all the intersection nodes inserted. The intersections can be

arranged in groups according to the area on which they operate.

Properties, Check and Settings: on the central block are displayed all the parameters regulating calculation, drawing and the way the intersection node selected works. Check page reports the values calculated by the policy and the comparison with the project values.

Typical intersections: on the right side it is possible to define, only for AT-grade intersections (linear or on roundabout), the possible typical intersection to be used to build edge polylines.

General information about intersections

Managing the intersections allows to solve in 3D and from every point of view (planimetry, profile and sections) every kind of intersection. The management does not provide for the horizontal design of the axes involved, which must be already present in the project; by the parameters defined for each

intersection the tool supplies some information, graphic and of other kind, which is then used by the different procedures of section calculation and generation of project planimetry.

In particular, dynamic design can manage, for each intersection, the data defined in the intersections and regenerate edge polylines; the application of typical sections on axes starts here, as well as the

construction of the project planimetry and of the final project model.

Intersection types

The types of intersection managed by the tool are the following:

AT-grade intersection By linear AT-grade intersection we mean all those intersections which are performed between two axes, when none of the two is a roundabout, with an angle of incidence between 40° and 160°. For angles of incidence below 40° or over 160° it might be necessary to manage the

intersection as a lane entry/exit.

The drawing of intersection edges can be obtained by inserting a typical intersection; it is also possible to solve the intersection by using edge polylines that can be inserted and defined even if they do not come from a typical intersection.

Roundabout intersection: it is the intersection between axes that meet in a roundabout.

The drawing of intersection edges can be obtained by inserting a typical intersection; it is also possible to solve the intersection by using edge polylines that can be inserted and defined even if they do not come

from a typical intersection.

Lane entry/exit: it is when a secondary axis converges or streams out (parallel or not) of a main axis. To be used, for example, in interchanges for lane entry /exit.

ProSt

89

Lane division: it is when an axis ends and continues on two separate axes.

Commands for the management of intersections

Add intersection: the command allows to define a new intersection in the project. The new intersection can create a new group of intersections or be included in an existing group.

Delete Intersection: the command allows to delete a group of intersections.

Add secondary axis: the command allows to add a new axis to a group of existing intersections. It

is better to use this command only to add a new intersection axis to the intersection group of a roundabout.

Remove secondary axis: the command removes an intersection node from a group of intersections.

Note: Removing the intersection axis does not remove the axis but only the information concerning

the axis inside the intersection (typical intersection, automatic drawing of edges, etc.)

Rebuild intersection: the command activates the intersection rebuild procedure; the operations performed depend on the kind of intersection.

AT- grade intersection (linear or on roundabout) with defined typical intersection:

The typical intersection scheme is inserted in the intersection area between the two axes.

In the main axis longitudinal profile the reference is displayed, reporting the station where the

intersection with the secondary axis is situated and its elevation on axis if available.

In the secondary axis longitudinal profile two references are displayed, which are referred to the station and to the elevation of the intersection with the main axis and with the main axis edge.

Such references are necessary to allow a correct vertical design of the secondary axis.

AT- grade intersection (linear or on roundabout) without defined typical intersection:

In the main axis longitudinal profile the reference is displayed, reporting the station where the intersection with the secondary axis is situated and its elevation on axis if available.

In the secondary axis longitudinal profile two references are displayed, which are referred to the station and to the elevation of the intersection with the main axis and with the main axis edge. Such references are necessary to allow a correct vertical design of the secondary axis.

Lane entry/exit

In the planimetry the polyline is calculated and inserted, which represents the leader along which the elevations are projected from the main axis to the secondary axis.

In the planimetry the polyline is calculated and inserted, which represents the curve filleting the

shoulders of the two axes.

In the planimetry the polyline is calculated and inserted, which represents the cut line along which to cut the cross sections of the two axes; the cut is necessary to delete the overlapping

areas. The cut is limited to the external part of the axes sections, where they overlap.

In the secondary axis longitudinal profile the profile polyline is calculated, which represents the projection of the main axis elevations; the polyline will be used to calculate the project elevations which will assure the continuity of the road surface.

The polyline is completed with a grade line segment, whose slope is that of the last polyline segment calculated; the grade line represents the start element of the design concerning the remaining part of the

lane entry/exit.

Lane division

The intersection Lane division is formed by three axes: the main axis which ends and subdivides into two new axes called Reference axis and Intersection axis.

In the longitudinal profile of the reference axis a reference is inserted, reporting the final

elevation of the main axis; moreover, a grade line segment is inserted, representing the

ProSt

90

continuation of the longitudinal slope in the final segment of the main axis. In this way, it is possible to complete the design of the reference axis preserving the continuity with the main axis.

In the longitudinal profile of the secondary axis a reference is inserted, reporting the station and the start elevation of the reference axis. Moreover, another reference is inserted, reporting the

station and the elevation of the reference axis on the point where the division of the two axes shoulders occurs.

In the longitudinal profile of the secondary axis a profile polyline is calculated, representing the projection of the reference axis elevations; the polyline will be used to calculate the project elevations which will assure the continuity of the road surface.

In the planimetry the polyline is calculated and inserted, which represents the cut line along

which to cut the cross sections of the two axes; the cut is necessary to delete the overlapping areas. The cut is limited to the external part of the axes sections, where they overlap.

Regeneration command can refer to an entire group of intersections or to a single intersection; to regenerate a group press the button after selecting in the table the row referred to the group heading; vice versa, to regenerate a single intersection, press the button after selecting the intersection desired.

Update intersection: The command performs a check on data and on the settings defined for the

intersection; the check has the purpose of verifying that, according to the data set, all the conditions are

respected for a correct management of the intersection. If the check gives a positive result, symbol

will appear near the intersection; otherwise, symbol will appear.

Move intersection: the two buttons allow to modify the intersections display order in the table.

Area excluded from the intersection "secondary exis name"

Distance before intersection point: it is the distance separating the intersection point between the two axes and the point in which the secondary axis intersects the main axis edge; this value can be

calculated by the tool by pressing button, which is displayed near the cell. This value is necessary so

that the correction of the transversal slopes does not involve the main axis but only the secondary axis; the main axis will keep its own transversal slopes, while the secondary axis slopes will be modified to manage the transition.

Distance after intersection point: to be used only in case of X intersections; it is the distance separating the intersection point between the two axes and the point in which the secondary axis intersects the main axis edge; in X intersections, the secondary axis meets both edges of the main axis; it is therefore necessary to specify both areas, before the intersection and after the intersection; this

value can be calculated by the tool by pressing value, which is displayed on the cell.

Intersection zone "secondary axis name"

Automatic calculation: by this option the tool can calculate automatically the area necessary to the length of the intersection on the secondary axis; by deactivating the option it is possible to define manually the values that define the intersection intervention limits as far as the secondary axis.

Distance before intersection point: it is the distance within which the intersection takes place, along the secondary axis, before the intersection point. The point determining the beginning of the intersection

can be indicated on screen by using button, which appears near the cell; the tool will then calculate the distance between the point indicated and the intersection point.

Distance after intersection point: it is the distance within which the intersection takes place, along the secondary axis, after the intersection point. The point determining the end of the intersection can be

By Settings page it is possible to check some intersection parameters:

Slope optimization: by activating this option the tool will be able to vary the transversal slope on

secondary axis, so as to fillet it with the main axis transversal slope.

Insertion of planimetry (edge) polylines: activates the insertion of the edge polylines defined in the typical intersection associated.

Insertion of references in profile: activates the calculation and the drawing of the intersection

references on the longitudinal profile; for this kind of intersection the following references are added in the profiles of the two axes:



Insertion of x-section in intersection main points: activates the automatic insertion of sections in

the intersection main points; the main points are:

start and end of intersection area on main axis

start and end of intersection area on secondary axis

in the main axis, on the secondary axis intersection point.

Recalculate cross-section on intersection area: by this option it is possible to activate, in the intersection areas, an automatic modification of cross sections which makes them perpendicular to the

right and left edge. Therefore, in the intersection area the section is no longer represented as perpendicular to the axis , but broken into a right and a left side: the right side will be perpendicular to the intersection right edge and the left side will be perpendicular to the left edge. Also the transversal length of the sections reflects this situation and will be calculated as perpendicular not to the axis but to the edges. The following image shows how the cross sections are displayed on the intersection.

Typical intersection manager

To solve the intersection, some planimetry polylines are necessary. They stand for the edges shape in the

intersection zone; planimetry polylines can be obtained by associating a typical intersection.

To associate a typical intersection to the current intersection press button; choose the typical intersection file to associate to the intersection. The typical intersections used in a project are automatically included in the project file. In this way the project can be completed by any user in any

computer, without having to copy manually the files from typical intersection libraries.

To modify a typical intersection assigned to an intersection press button; in this way, you gain access to the system by which to build and modify typical intersections. To remove the association with a

typical intersection press button.

Since the typical intersections used in a project are automatically included in the project file, a command

is available, which allows to extract a typical intersection so that it can be used in another project: for

such needs press button, which will activate a dialog box allowing to choose the name of the file to be assigned to the intersection, as well as the saving folder.

When it is impossible to use a typical intersection it is possible to solve the intersection by defining the polylines which determine the edges shape in the intersection zone; the polylines must be planimetry

polylines whose codes are among the ones provided by the tool for the left and right edges. By settings

ProSt

97

page of parametric design it is possible to manage the name which must be attributed to the polylines representing the two edges of the intersections.

Since edge polylines can belong to either axes, it is necessary to verify whether the option Share polylines with other axes is active for both axes, otherwise the tool could be unable to find the polylines necessary to the solution of the intersection. The option Share polylines with other axes is

managed as Axis properties filter.

Generate intersection

It is possible to generate the intersection defined by button, which will perform the following

operations:

the typical intersection scheme is inserted in the intersection zone between the two axes (if a

typical intersection has been associated);

The main axis longitudinal profile displays the reference reporting the station where the intersection with the secondary axis is situated and its elevation on axis if available.

In the secondary axis longitudinal profile two references are displayed, which are referred to the

station and to the elevation of the intersection with the main axis and with the main axis edge. Such references are necessary to allow a correct vertical design of the secondary axis.

The references calculated by the tool, and inserted in the secondary axis profile, allow to link ite project profile to the main axis elevations. The constraint can be carried out by building some grade lines as follows:





The first grade line ends on the elevation referred to the main axis edge, while the second grade line links to the elevation on axis. The grade lines built in this way create a constraint, between the secondary axis and the main axis, which is maintained also when the main axis elevations change.

Edge polylines, either inserted by typical intersection or not, must then be linked to the typical section right and left roadway.

The tool can solve tridimensionally the intersection according to the information it has received;

Dynamic design is the best tool to use to regenerate the project of the two axes and

display the final result.

Slope optimization: by activating this option the tool will be able to vary the transversal slope on secondary axis, so as to fillet it with the roundabout axis transversal slope.


Insertion of references in profile: activates the calculation and the drawing of the intersection references on the longitudinal profile; for this kind of intersection the following references are added in

the profiles of the two axes:

Recalculate cross-section on intersection area: by this option it is possible to activate, in the intersection areas, an automatic modification of cross sections which makes them perpendicular to the right and left edge. Therefore, in the intersection area the section is no longer represented as

perpendicular to the axis , but broken into a right and a left side: the right side will be perpendicular to

the intersection right edge and the left side will be perpendicular to the left edge. Also the transversal length of the sections reflects this situation and will be calculated as perpendicular not to the axis but to the edges. The following image shows how the cross sections are displayed on the intersection.

Volume calculation itself has been adapted to the new shape of the cross sections and an adjustment factor has been introduced to obtain a very precise calculation of the intersection zone areas and volumes. Volume calculation report displays the adjustment factor used in determining the totals.



To solve the intersection, some planimetry polylines are necessary. They stand for the edges shape

in the intersection zone; planimetry polylines can be obtained by associating a typical intersection.

To associate a typical intersection to the current intersection press button; choose the typical intersection file to associate to the intersection. The typical intersections used in a project are automatically included in the project file. In this way the project can be completed by any user in any computer, without having to copy manually the files from typical intersection libraries.



Since the typical intersections used in a project are automatically included in the project file, a command is available, which allows to extract a typical intersection so that it can be used in another project: for

such needs press button, which will activate a dialog box allowing to choose the name of the file to

be assigned to the intersection, as well as the saving folder.

When it is impossible to use a typical intersection it is possible to solve the intersection by defining the polylines which determine the edges shape in the intersection zone; the polylines must be planimetry polylines whose codes are among the ones provided by the tool for the left and right edges. By settings page of parametric design it is possible to manage the name which must be attributed to the polylines representing the two edges of the intersections.

Since edge polylines can belong to either axes, it is necessary to verify whether the option Share polylines with other axes is active for both axes, otherwise the tool could be unable to find the polylines necessary to the solution of the intersection. The option Share polylines with other axes is managed as Axis properties filter.

It is possible to generate the intersection defined by button, which will perform the following operations:

the typical intersection scheme is inserted in the intersection zone between the two axes (if a typical intersection has been associated);

The roundabout axis longitudinal profile displays the reference reporting the station where the intersection with the secondary axis is situated and its elevation on axis if available.



The references calculated by the tool, and inserted in the secondary axis profile, allow to link ite

project profile to the roundabout axis elevations. The constraint can be carried out by building some grade lines as follows:

The first grade line ends on the elevation referred to the roundabout axis edge, while the second grade line links to the elevation on axis. The grade lines built in this way create a constraint, between the secondary axis and the main axis, which is maintained also when the roundabout axis elevations change.

Edge polylines, either inserted by typical intersection or not, must then be linked to the typical section

right and left roadway.

Management of entry/exit lanes

It is when a secondary axis converges in or streams out of the main axis (parallel or not). To use, for example, in interchanges for entry/exit lanes.

To manage this kind of intersection, it is necessary to work with a main axis and a lateral axis, representing the entry/exit lane. The lane project direction must follow the traffic direction: if it is an exit lane, the axis start must be positioned next to the main axis, while if it is an entry lane, the end of the

axis must be next to the main axis. Before inserting the intersection points, it is better to set the main axis vertical design.

By Settings page it is possible to check some parameters of the intersection:

Slope optimization: by activating this option the tool will be able to assign the secondary axis the same transversal slope as that of the main axis, with the purpose of keeping a single slope in the segment in which the two axes are not completely independent.

Lanes size from planimetry (edge) polylines: activates the use of eges polylines for the calculation of roadway size in the intersection area. To be used in particular situations, such as variations in the roadway width.

Insertion of planimetry (edge) polylines: activates the insertion of a circular curve between two shoulders.

Insertion of projection polylines in planimetry: the tool draws the planimetry polyline along which the main axis elevations are projected towards the secondary axis.

Insertion of projection polylines in profile: a polyline reporting the main axis projected elevations is calculated and inserted in the secondary axis profile; the polyline represents the project profile to follow

in order to maintain a surface continuity with the main axis. The polyline is completed with a grade line whose slope is equal to the final slope of the last polyline segment; in this way it is possible to complete the altimetric design of the remaining part of the alignment.

Insertion of cut polyline: in the planimetry a polyline is calculated and drawn, which corresponds to the position along which the cross sections of the two axes are cut. The overlapping between the sections of the two axes, both of part of the pavement and, mostly, of the shoulders and the external slopes, is automatically removed along the cut polyline calculated by the tool. By deactivating this option it is

possible to draw a cut polyline and assign it a code chosen among the parametric design settings.

Insertion of reference in profile: activates the calculation and the drawing of the intersection references on the longitudinal profile; for this kind of intersection the following references are added in the profiles of the two axes:

Lane division management

It is the case in which an axis ends and continues on two distinct axes.

To manage this kind of intersection it is necessary to have three

axes:

1. the main axis, which ends and from which the other two axes start. The situation could also be the opposite: the main axis starts where the other two axes finish.

2. The reference axis, which is the first to be designed after the main axis. The project direction must follow the traffic direction.

3. The secondary, or intersection, axis, which is the last to be projected, since its elevations depend on the reference axis. The project direction must follow the traffic direction.

The design sequence on which the system is based is the following:

planimetric definition of the three axes

vertical design of the main axis

insertion of the Lane division intersection and generation of the intersection; the generation adds

some information in the reference axis profile, which are necessary for the vertical design.

According to the generation, the reference axis will have all the information necessary to complete the vertical design.

Regeneration of the intersection to add some information to the secondary axis profile, which is

necessary to carry out the vertical design.

Also the secondary axis now has all the information necessary to complete the vertical design.

Typical section

By this page it is possible to set the features and the size of the road template to be used.

Creation

In this page it is possible to set the modes and the features concerning the creation of the project

planimetry.

Generation mode: The project planimetry generation modes are two:

From cross-section: from complete cross-sections it is possible to obtain the road alignment project planimetry. In this case, the result obtained depends completely on the content of the cross

sections; any element contained in the cross sections can be projected onto the planimetry.

From typical section: in this case the project planimetry is obtained directly by inserting one or more typical sections along the axis; this mode does not require the project to have been developed completely, as far as the cross sections; it is sufficient to have an horizontal alignment

ProSt

122

and the corresponding vertical profile. The result obtained does not depend on the cross-sections and it is therefore up to the user to assure the correspondence between the project planimetry obtained in this way and the content of the cross sections.

Creation mode: Three different project planimetry creation modes are available, which differ according to the level of accuracy of the result they produce and their creation speed. Depending on the project

phase which is being performed, it is possible to choose the most suitable creation mode (e.g.: fast and less accurate during the project, slow but accurate during the execution of the final reports).

No interpolation. By this mode the tool calculates for each point in the axis a typical section and obtains automatically the crossing points between cut and fill. This mode returns the most accurate result, but it also requires more time to be carried out. To be used at the end of the project for the final drawings.

Interpolation on transition zones. By this mode the tool calculates for each point in the axis a

typical section and interpolates the typical sections in the crossing points between cut and fill, not

calculating the exact crossing point. This mode is always accurate and it is a little faster than the one with no interpolation.

Interpolation by typical sections (Suggested mode). By this mode the tool calculates the typical sections only on generation main points and interpolates the typical sections of the axis intermediate points. This mode is the fastest one but it is also the one that gives the less accurate

results. To be used during the design phase.

Maximum generation step: this is the maximum distance used by the tool between a typical section and the following one. The tool automatically inserts some typical sections in the critic points of the alignment: element tangent points, passage points between cut and fill. On curvilinear elements (clothoids, parabolas, horizontal curves) the distance between a typical section and the following one is such as to make it possible to obtain an optimal representation of the curve; this is true also for vertical curves.

Generation main points: this group of options allows to define on what points, besides the ones defined

by horizontal and vertical elements, to calculate the typical sections so as to increase the accuracy of the planimetry of project. Generation main points are the following:

Cut/fill passage points: This option integrates the crossing points between cut and fill in the alignment axis.

Superelevation and widening vertexes: This option integrates the transversal slope change points and the widening points calculated for the axis.

Cross section: This option integrates the points near the sections stations along the alignment.

Planimetry and profile polylines: This option integrates the projection of the axis planimetry and profile polyline vertexes.

Values by station: This option integrates the points near the stations of the axis variables situated in the axis.

Create planimetry of project: with this option is possible to specify to obtain the drawing of the

project-planimetry.

Create planimetry polylines from cross-section flags: by this option it is possible to activate the automatic creation of planimetry polylines from the flags set in the sections.

Create profile polylines from cross-section flags: by this option it is possible to activate the automatic creation of profile polylines from the flags set in the sections.

Superelevation symbols: by activating this option, the planimetry of project command allows to obtain the display of the superelevation on curve on main points.

Create design model: this option specifies that the project digital model has to be calculated. Some 3D faces will be created, linking some section elements specified by the button Set transversal elements.

Delete previous elaboration: by activating this option, the tool automatically cancels all the results

obtained by the previous elaborations.

Such settings can be applied at the same time also to other axis subprojects, by using the Apply command which appears either on the heading of a group of settings or on a single setting.

Real Time Design

Introduction

Real Time Design window allows to display and modify the typical sections defined by real time parametric design in any point of the axis. This new tool allows to analyse quickly the working of typical sections, section data, values by station, planimetry and/or profile polylines at a certain date or axis section. It also allows a precise modification of the object properties in certain zones of the axis, leaving

unchanged the values defined in the typical section.

In the typical section window both typical section and terrain section are displayed according to the calculation settings defined for the axis selected.

Real Time Design window is dynamically linked to the other graphic windows of the tool. In fact, moving from/to planimetry, profile or parametric design automatically activates this window. It is possible to shift along the axis both by station and by sections, and it is possible to use both navigation bar and text field or the arrows situated in the lower part of the window.

Real Time Design window reports in its upper part a toolbar for the management of the graphic window and for the modification of the typical section, in the middle it displays the preview of the typical section at the current station, and at the bottom it reports a scroll bar and some information about the section.

Toolbars

In the toolbar for the management of the graphic window the following commands are available:

Regen drawing: allows to regenerate the section drawing and update the axis data (project elevations, superelevations, widening, planimetry/ profile polylines, etc.)

Zoom in: Allows to increase the zoom on the graphic window.

Zoom window: Allows to zoom on a rectangular area in the graphic window.

Zoom all: Allows to display all the typical section objects inside the graphic window.

Settings: This button displays a menu from which it is possible to define the graphic window display settings.

Section for project planimetry: displays only the objects used for the generation of the project planimetry, according to the settings defined in the section codes. If this option is active, displaying the typical section will be faster, since some typical section objects will not be drawn.

Section header: Displays axis name and section data (name, station, project elevation) on the

upper left corner of the graphic window.

Planimetry polylines: Displays with graphic references the position of the planimetry polylines in the section. The polylines are displayed by vertical hatches reporting at their top and bottom the code and the distance from axis. In case of 3D polylines also a mark on their elevation is displayed.

By submenu items it is possible to display the references either to all the polylines or only to the ones used by the typical section and display, or not, the elevation mark.

Planimetry polylines: Displays with graphic references the elevations of the profile polylines in the section. The polylines are displayed by horizontal hatches reporting at their sides the code and the elevation.

By submenu items it is possible to display the references either to all the polylines or only to the ones used by the typical section.

Copy current terrain on: Allows to save the terrain currently visible in the graphic window in one of the four customized terrains, so as to use them in the typical section builder in order to simulate

a more realistic terrain during the insertion of such particular objects as benching, stripping, terrain recovery etc.

Help on line : This button displays a menu by which it is possible to gain access to the help on line and to the information concerning the version of the typical section builder. In the toolbar for the modification of the current section the following commands are available:

Modify "Current Section": If this button is active, the changes made on the properties of the objects are applied only to the axis as well as to the current station and do not modify the values

of the typical section (the ones set in “Typical section builder”). In this way it is possible to modify the typical section only on some segments of the axis, without having to create each time different typical sections.

Information

The lower part of the window reports section data, values by station, planimetry and/or profile polylines

at a certain station of the axis.

Such information can be hidden or made visible by pressing on button, situated on the right of the page. Otherwise, from the pull down menu of the subproject it is possible to select the axis subproject to

display in the Real Time Design window.

By the scroll bar it is possible to change the station or the section currently visible in the graphic window; according to the station selected, the tool will display the corresponding typical section, according to the settings defined in the parametric design. By the options &rdquor;Station” and &rdquor;Sections”, reported above the scroll bar, it is possible to choose the scroll mode along the axis; the text field on the

right of the bar allows to set manually the value of the station or the number of the section to be seen. The scroll can be performed either by the bar or by the arrows positioned past the text field.

The information the tool displays are subdivided into three pages. The first reports the section data, the second reports the values by station, and the third reports the planimetry and profile polyline data.

“Section” page reports on the left the section data (station, terrain elevation, project elevation, elevation difference, Coordinate E, Coordinate N, angle), on the right the superelevation and widening data (including the sight ones) referred to the current station/section.

“Value by station” page reports the values by station defined for the axis selected along with the values at the current station/section. The values by station used by the typical sections defined for the axis are

displayed, which, if pressed, selects the object and opens the table for the modification of the values by station.

Pressing the mouse right button on the table of the values by station activates a local menu with the

following commands:

Display value by station: Selects the object corresponding to the value by station selected and opens the table for the modification of the values.

Delete value by station: Deletes the value by station selected.

Link value by station: Allows to link the value by station selected to a property of the current typical section. This command is visible only when the value by station is used by no axis typical

section and “Modify single section” mode is active.

“Planimetry and profile polyline” page reports the planimetry and profile polylines which can be used by

the typical sections of the axis selected; the used ones are marked by icon.

The polylines are subdivided into two groups, one for the planimetry polylines and the other for the profile polylines; planimetry polylines report code, description, distance from axis and elevation, both on the left and on the right, while profile polylines report code, description and elevation.

Working mode

Real Time Design window has three working modes, which are the following:

1) Typical section check: This is the window main working mode and allows to display in real time the typical sections defined in the parametric design as well as the terrain sections in any point of

the axis.

2) Modify current section: by this mode it is possible to modify the properties of the objects that make up a typical section in certain segments of the axis without having to modify the typical section values.

3) Typical section builder: by this mode it is possible to modify the currently visible typical section.

Typical section check

Typical section check is the Real Time Design main mode and allows to display the typical sections defined in the parametric design at any point of the axis with all the generation parameters applied.

By this mode the user can see the typical section as if inserted in a section at the station indicated; in

fact, the tool inserts the typical section in the real terrain calculated for that station, according to the settings defined for the axis.

Moreover, in information page, all the section, value by station, planimetry and profile polyline data are updated in real time.

By this mode the user can therefore carry out an check along the axis even before updating sections and project planimetry.

Modify current section

This mode is activated by pressing button and allows to modify object and typical

section properties in certain segments of the axis.

ProSt

128

When this mode is active, the left side of the window displays the table of object properties, reporting the values assumed by the object when it is being inserted at a certain station or in the section selected. Besides, it is possible to select the objects directly from the graphic window. The changes made on the object properties by this mode will not modify the typical section values defined in advance, since they will be applied only to the station or section currently visible.

Besides modifying directly the property values, by button, positioned on the left of the property name,

it is possible to open a window in which to set the values by filling in a table and defining also the transition mode between a value and its consecutive.

The tool provides for three types of transition:

1. Linear: this transition, in the station interval between itself and its consecutive, interpolates linearily the value of the property with the following one.

2. Constant: this transition, in the station interval between itself and its consecutive, keeps the property value constant.

3. None: this transition, in the station interval between itself and its consecutive, uses the value defined by the typical section.

ProSt

129

By button it is possible to activate or deactivate the dynamic updating of the typical section when

moving in the table or modifying the values. By button it is possible to import the values by station of another object property , axis data (superelevation, widening, terrain/project elevations, etc.) and planimetry/profile polyline data.

Besides, by button it is possible to link the property to a planimetry or profile polyline. If the button displayed is grey, the property can only be defined by station/section, while if it is orange the propetty

can be linked also to planimetry and profile polylines.

To link the property to a planimetry or profile polyline it is sufficient to select the polyline type and its

code in the pull down menu. If a property has some values defined by station, in the name column

icon is displayed, while if it is linked to a planimetry and profile polyline . icon is displayed.

Typical section builder

This mode is activated by pressing button and allows to modify the typical

section currently visible in the graphic window.

When this mode is active, the typical section values already defined can be modified and they can also be

integrated with other objects.

For further information about typical section builder consult the chapter of the help on line.

Dynamic design Dynamic design is a completely new method which does not involve a single module or graphic window but the whole road design software.

By the data and the relationships inserted in the parametric design, the dynamic design can automize the whole process of project creation and modification, taking care of performing either automatically or on demand, a series of repetitive operations which otherwise should be specified automatically by the

operator.

Besides, some smart changes are applied by the software to the vertical design: in case a horizontal alignment is modified, the tool can correct the project longitudinal profile (grade lines and vertical curves) to adapt it to the new alignment length.

Dynamic design therefore determines a global updating of all the project elements and data.

reposition cross sections

recalculate superelevation and widening

recalculate terrain sections and insert typical section

update axis variables and planimetry polylines

regenerate project planimetry

recalculate terrain longitudinal profile

correct project longitudinal profile (grade lines and vertical curves)

update profile polylines

recalculate areas and volumes

Each of these phases can be excluded by the automatic updating made by dynamic design. Moreover, the automatism is so powerful that it can update automatically also the road intersections defined inside a project; the (horizontal and/or vertical) modification of one of the intersection axes determines the automatic regeneration of the whole intersection and its data. Dynamic design can be activated in

different ways by planimetry, profile and cross-section graphic window.

Dynamic design

In the window of dynamic design it is possible to choose what axis data to update automatically, customize updating parameters, activate dynamic updating, generate the current axis or all the axes available in the project.

The window displays two visualization modes, an extended one and a reduced one. The extended mode displays both the main commands and the table of axes data, while in the reduced one only the main commands are displayed. To pass from a mode to the other click twice on the window heading.

Reduced View Extended View

In the pull down menu situated atop the window it is possible to display a list of the axes available in the project and select the one to be updated.

In this list the axes containing changes, and therefore needing to be updated, are marked by icon,

while those containing no changes are marked by icon.

The first item in" “All” list allows to set the data to be updated for all the project data; if a datum

displays icon, this means that its updating is active only for some axes.

By the option Dynamic design from axis it is possible to have all the axis data updated any time the alignment and/or its elements are modified. If this option is active the tool automatically surveys the changes made, selects the data to be updated and performs the updating. The choice of the data to be

updated is carried out so as to reduce as much as possible the time required for the generation. In order

to force the calculation of all data it is necessary to activate the option Activate calculation for all axis data.

Warning: The generation could take some minutes. It is therefore recommendable to activate the option Dynamic generation from axis only for small changes, while for important changes it is better to deactivate the option, make the changes, and then press Generate axis button to update all data.

By the following table box it is possible to activate the automatic updating of the corresponding datum.

By pressing Generate axis button it is possible to update all the data that have been modified. If the

item All is active, the tool will update all the work axes.

If the current axis is used in an intersection, the following window will be displayed:

If you answer Yes the software will update not only the current axis but also all the axes and intersections linked to it; if you answer No, only the current axis will be updated.

Warning: the generation of the current axis with all the linked axes can take some minutes, so it should be performed only to make changes which may affect the intersections linked to it, such as the change of

the project longitudinal profile, or the change of the horizontal alignment in the intersection zone.

In Axis generation group it is possible to select and customize axis data, and activate the dynamic updating.

By the option Dynamic generation from axis it is possible to have all the axis data updated any time the alignment and/or its elements are modified. If this option is active the tool automatically surveys the changes made, selects the data to be updated and performs the updating.

Axis data table reports all the data the tool can update automatically, subdivided according to the module they belong to (planimetry, profile and sections).

By Process column check box it is possible to activate the automatic updating of the corresponding datum, while by pressing Configure.... it is possible to customize the datum updating parameters.

The axis data the software automatically updates are the following:

Planimetry

Automatic sections: If this option is active the tool automatically repositions the sections situated along the axis and inserts the automatic sections according to the rules set. The software repositions the sections according to their typology.

Cross-section by point (Orange circle with letter P): cross-sections by point are

repositioned according to the reference planimetric coordinates indicated in the planimetry during the insertion or conversion phase. For example, if a cross-section by point has survey point 101 as

reference, the software will always reposition it on the projection of point 101 on the axis.

Cross-sections by station (Yellow circle with letter S): Cross-sections by station are

repositioned according to the value of their station. For example, if a section by station has 110 as reference station, the software will always reposition it at station 110.

Automatic cross-sections (Red circle with letter A): Automatic cross-sections are

repositioned, if possible, according to the rules defined (insertion step, main points, etc.), otherwise they are deleted and then inserted again.

Free cross-sections (Green circle with letter L): Free cross-sections are not repositioned and are defined only by their planimetric position.

ByConfigure…; text it is possible to customize the insertion parameters of the automatic cross-

sections.

Superelevation and widenings: If this option is active the tool calculates superelevation and widening following the reference policy and uses them for the axis.

Warning: If customized superelevations and/or widening are used, it is necessary to deactivate this option, to avoid loosing the data inserted at the next axis updating.

Typical sections: If this option is active, the tool updates the typical sections intervals defined for the axis, modifying the values of start and end stations, so as to adapt them to the new alignment.

Geometric section properties: If this option is active, the tool updates the geometric features defined for the axis, modifying the values of start and end stations, so as to adapt them to the new alignment.

Road intersection: If this option is active, the tool updates the drawing of axis edges in the intersection areas and the references to the intersections in the profile.

Project planimetry: If this option is active the tool generates the project planimetry and/or the axis mathematical model. By Configure... text it is possible to customize the project planimetry generation parameters.

Longitudinal profile

Terrain profile: If this option is active the software calculates the terrain profile along the axis. By

Configure…; it is possible to customize terrain profile calculation parameters.

Grade lines and vertical curves : If this option is active the tool updates the project longitudinal profile (grade lines and vertical curves), so as to adapt it to the new axis length, keeping constant the grade line slopes and the curve radiuses. Besides, if the grade lines are linked to the intersection references in the profile the tool repositions the grade lines so as to adapt them to the new position of the references.

Additional profile: If this option is active the tool will update the stations of supplementary profile vertexes so as to adapt them to the new alignment length.

Profile polyline : If this option is active the tool will update the stations of profile polyline vertexes so as to adapt them to the new alignment length.

Profile supplementary data : If this option is active the tool will update the stations of supplementary

data so as to adapt them to the new alignment length

Cross-section

Terrain section: If this option is active the tool calculates the terrain of the sections situated along the axis. By Configure…; it is possible to customize terrain calculation parameters.

Design section: If this option is active, the software inserts the project typical sections into the axis sections, according to the intervals defined by parametric design. If the elements of the typical sections inserted automatically are modified manually inside a section window, the tool converts the section into a

free section, so as to avoid the loss of the changes made, since the elements inserted automatically can be deleted and modified in any moment by automatic insertion procedure. If some elements are inserted manually in a section window, the tool converts the section into a section by point so as to keep the

section planimetric position, and the elements inserted cannot be deleted or modified by the automatic insertion procedure Areas and volumes: if this option is active the tool calculates the areas and the volumes of the sections along the axis.

Planimetry The planimetry module available in ProSt contains all the commands for the insertion, management and drawing of horizontal alignments.

The design of road axes is carried out interactively, in the software graphic window, also overlapping the survey performed and/or numeric or raster format maps.

The alignment can be defined by two modes: by vertexes and by curves. The horizontal elements the tool

manages are horizontal straights, curves, hairpins and every kind of normal and multi-parameter clothoids: straight-circle, egg-shaped, reversing clothoids.

Designing interchanges, even very complex ones, becomes much simpler by managing multiple axes, which allows to have in a single archive more alignment elements at the same time. To design an interchange is therefore sufficient to build a certain number of alignments (main alignment, entry/exit

lanes, etc) inside the same graphic window. The road intersection can be solved also by building a 3D model of the crossroads; it is possible to build models complete with traffic divider pavements, islands,

widening, gutters, sidewalks.

By policy check it is possible to verify whether the axis project parameters are consistent with the policy selected. The software supplies a detailed report for any element (horizontal straights, curves, clothoids, parabolas), in which it checks the consistency of the parameters (lengths, radiuses, A parametrs) with the policy and suggests the minimum and maximum values to be adopted. The check is carried out also on the intersections.

With planimetry polylines it is possible to carry out the axis offset in different ways, building very quickly

road obstructions, ditch shoulders, etc.

Such polylines can be used in profile and sections modules as references to the design.

The insertion of the sections in the axes can be performed in a totally automatic mode, by positioning the

sections on the main points of the alignment (tangent points, bisector) and at regular intervals. Moreover, it is possible to insert the sections manually, by indicating the position on the axis or specifying the insertion station. The software can calculate automatically superelevation and widening on curve,

according to the policy set. From the project maximum and minimum speed set and from the percentage of heavy traffic the tool calculates, for each station, the rotation due to speed and the widening due to the percent of heavy traffic. If there are no clothoid curves it is possible to set some equivalent lenghts, along which to apply the rotation and widening variation. After inserting the alignment elements it is possible to obtain automatically the geometry annotation complete with all the dimensions. The horizontal straight lengths and the curve tangents are dimensioned. For any circular curve a table is drawn, which reports the main data such as radius, lengths,central angle, bisector and tangent. The

clothoid long and short tangents are dimensioned. Moreover, the clothoid features are reported, such as A parameter, shifting, tau angle and length.

Dimensioning and tables are completely modifiable and it is possible to set both the character size and the layer they belong to. It is possible to obtain the project planimetry from the cross sections or from

the typical sections and also to obtain the 3D model of the section elements; this 3D model can be automatically merged with the terrain model, allowing to see the designed road inserted in the situation surveyed.

The software includes what is called Parametric design, which is a design method allowing to define all the specific parameters of the axis to be designed, among which we can mention: roadway and roadside width, transversal slopes, the typical section to be used in the different segments. The window of parametric design therefore becomes a sort of headquarter of the axis which groups together the whole project information, and, in case of modification of the horizontal or vertical alignment, allows to reinsert the typical sections and obtain again the road planimetry of project and final model. ProSt includes the

dynamic design, a completely new methodology which does not apply to a particular module or graphic window but the whole software of road design. By the data and the relationships inserted in the parametric design, the dynamic design can automize the whole process of project creation and modification, taking care of performing either automatically or on demand, a series of repetitive operations which otherwise should be specified automatically by the operator.

Besides, some smart changes are applied by the software to the vertical design: in case a horizontal alignment is modified, the tool can correct the project longitudinal profile (grade lines and vertical curves)

to adapt it to the new alignment length.

Axis data table reports the data the tool can update automatically, subdivided according to the module they belong to (planimetry, profile and sections).

By Generate column check box it is possible to activate the automatic updating of the corresponding datum, while by pressing on Configure... it is possible to customize the updating parameters.

The axis data the tool automatically updates are the following:

Planimetry Automatic section: If this option is active the tool repositions automatically the sections situated along the axis and inserts the automatic sections according to the rules set. The tool repositions the sections automatically, according to their typology:

Cross-section by point: Sections by point are repositioned according to the reference

point indicated in the planimetry during the insertion or conversion phase. For example, if the point of reference of a section by point is surveyed point 101, the tool will always position it on the projection of point 101 on axis.

Cross-sections by station: Cross sections by station are repositioned according to the value of their station. For example, if the reference station of a cross section by station is 110, the

tool will always position it on station 110.

Automatic cross-sections: If possible, automatic sections are repositioned according to

the rules defined; otherwise, they are deleted and inserted again.

Free cross-sections: Free cross sections are not repositioned.

By Configure… text it is possible to customize automatic section insertion parameters.

Superelevation and widenings: If this option is active the tool calculates superelevation and widening following the reference policy and uses them for the axis.

Warning: In case customized superelevation and/or widening are used, it is necessary to deactivate this option. Otherwise, at the following axis updating the data inserted might be lost.


Geometric section properties: If this option is active, the tool updates the geometric features defined for the axis, modifying the values of start and end stations, so as to adapt them to the new alignment.



Longitudinal profile Terrain profile: If this option is active the tool calculates the terrain profile along the axis. By Configure... text it is possible to customize the terrain profile calculation parameters.

Grade line and vertical curves: If this option is active the tool updates the project longitudinal profile

Drawing filters tab

By this page you can check the visualization of all the entities of the active subproject: if the check box is

active, then the corresponding entity will be visible, if not it will be invisible.

Drawing filters intervene on the visibility of the entity, independently from the layer the entity belongs to; in this way it is possible, for example, to choose to make visible all the sections, even if they belong to different layers.

Without this option it would have been necessary to freeze all the layers containing the sections, with the risk of freezing all the other entities.

If an entity is set as visible but the layer it belongs to is freezed or deactivated, the entity is not displayed.

By selecting the option All subproject the current subproject settings are activated in all the other subprojects. In this way, by a single command it is possible, for example, to make the points of all the subprojects invisible, without having to activate each project and for each of them make the points invisible. If the option Current Subproject is active, the settings are assigned only to the current

Alignment elements

An axis is a succession of circular or rectilinear elements linked by variable-radius transition curves( clothoids or parabolas) which grant the regularity of the bend. Elements are linked to each other keeping their condition of tangency. Elements can be linked also without transition curves; in this case the condition of tangency is kept but not the continuity of the bend.

A planimetric axis can be defined in two ways:

1. Axis by vertexes: it is the traditional method used to define the traverse station defining

vertexes and on which curves are inserted; this method allows to insert also reversing and egg-shaped clothoids but it is not very useful for modifying what has been built. This work mode involves the use of four different elements: horizontal straight, circular curve, clothoid, parabola.

2. Axis by curves: by this axis insertion mode it is possible to create elements (straights or

curves) meeting specific conditions and relations between the elements; such rules are saved in the element, so that a modification of the element data can allow to build the axis. This method

allows, for example, to define unavoidable passage points for the elements; any modification made on adjacent element/s will force the tool to make the axis pass by the points defined. Unlike the previous method, the method by curves manages a single type of element, the curve, which contains transition curves; a special curve is the straight, which is a curve with infinite radius and without transition curves.

In defining an axis it is not possible to use a "mixed" method; if we start building an axis using the method "by vertexes" it is not possible to insert elements of a different kind and vice versa.

It is however possible to turn an axis defined by curves into a traditional axis defined by vertexes; in this case, after the transformation it will be no longer possible to go back to the initial situation.

The planimetry sort function allows to set the start vertex of the alignment and to keep in order the elements that make up the road axis so that all the elaborations performed are correct.

So, once modification and axis insertion functions have been performed, it is better to carry out this

elaboration in order to find possible anomalies in the axis.

It is also possible to obtain automatically some axis elements as offsets of elements of an already existing axis.

Axis elements can be imported from AutoCad DXF files and also exported by DXF files.

By policy check it is possible to verify whether the axis project parameters are consistent with the policy selected. The software supplies a detailed report for any element (horizontal straights, curves, clothoids,

parabolas), in which it checks the consistency of the parameters (lengths, radiuses, A parametrs) with the policy and suggests the minimum and maximum values to be adopted.

The current axis is drawn with a lineweight which allows it to be recognized among the other axes.

Set as current axis A new option allows to set an axis current in a fast way. It is sufficient to select by the mouse right button one of the elements (horizontal straights, curves, clothoids) that make up the horizontal axis; the following menu will appear:

Select the item Set as current axis; the axis the element selected belongs to will become the current axis.

Open profile from planimetry By pressing the mouse right button on an element of the axis it is possible to open the graphic window of the corresponding profile. This simple command allows to avoid different manual operations which required to set the axis as the current axis and then to open the profile window.

In order to activate the command press the mouse right button on an element

of the axis; select Open profile from the local menu. It will open the graphic window of the axis profile the element selected belongs to.

Axis by vertexes

The planimetric management allows the management of the following axis elements:

Horizontal straights

Horizontal curves and hairpins

Clothoids

Parabolas

Curves complete of horizontal curves and clothoids

Roundabout

Normally, in order to insert a road axis, first you have to insert an axis traverse through the insertion of horizontal straights; it is then possible to add, in the vertexes, circular curves and in the end, clothoids.

ProSt

153

Circular curves can be simple (circular curve between two horizontal straights) or compound (polycentric curve and polycentric spiral); dialog boxes have been arranged in order to insert the respective data.

It is possible to create a road axis by inserting the elements according to their position along the axis. The alignment can therefore start with a circular curve or with a clothoid, and does not need, as does the previous method, that the alignment begins and finishes with an horizontal straight. It is of course

possible to integrate the two methods, thus meeting any kind of planning needs.

Insertion and management of the alignment elements can be performed graphically from the CAD window or from a particular window, called Axis table, which allows to manage alignment data in an analytical way.

It is possible to modify the axis by moving with the cursor the alignment vertexes or by stretching the horizontal curves. In moving the vertexes it is possible to set a free offset, or an offset along one of the two tangents defined by the horizontal straights connected.

Horizontal straights It is possible to insert the horizontal straight of a road in two ways:

1. Insertion by 2 points;

2. Insertion by specifing start point, direction and length;

Insertion by 2 points The insertion of a horizontal straight by two points is carried out in one of the following ways:

Insert by Radius/Tangent/Point/poLycentric/<R>: L

A polycentric horizontal curve can be inserted by specifying the radius of the arcs that make up the curve and the respective angular ratio. The polycentric horizontal curve can be Short or Long; in the second case the deviation angle is the difference between the round angle and the vertex angle and therefore there will be a situation in which the two horizontal straights will be connected.

In the right part of the window the tool displays the vertex angle between horizontal straights and the

corrensponding deviation angle.

Radius: value of each arc radius.

Radius ratio.: ratio between different arc radii; changing the ratio between radii, all arc radii are

re-calculated.

ProSt

157

Angles ratio: ratio between the angles of the different arcs forming the curve.

Angles: angular value of each arc; this column can't be edited.

Length: length of each arc; this column can't be edited.

If you want to insert a spiral horizontal curve betweeen two horizontal straights in order to build interchange ramps, you can select Polycentric spiral tab:

This kind of curve meets the two main needs in the construction of ramps; in fact, the ramps must have an adequate length allowing to accelerate and decelerate easily and allowing to perform planimetric variations even higher than 270° degrees.

In spirals, each speed variation corresponds to a radius variation of the same sign: the value of the radius changes each time the length of the horizontal curve corresponds to the covering time set (usually 2 seconds).

In this tab, you can set the following data:

Start speed: start speed on the first horizontal straight.

Acceleration: acceleration value in m/(sec*sec); the value is negative for decelaration ramps.

Single arc covering time: time necessary to cover each arc of the spiral.

According to the values input, the tool calculates the Number of arcs, the End speed and the two radii: Start and End. In order to insert the curve between the two horizontal straights selected, press button Calculate polycentric: in this way data calculated are reported on the table of the first tab and pressing Apply button the tool starts the input.

List of the entities managed by the tool In the left part of the window all the entities are reported which can be used to create an alignment.

List of alignment elements In the upper part on the right, all the elements forming the alignment are listed. Each line reports the

object (Horizontal straight, Clothoid, Horizontal curve, etc.), the state (Linked, Not linked) and the main properties of the element. The state is a very important value as it allows to see whether an element is sorted or not.

Element properties In the lower part on the right all data are reported of the element selected in the previous table.

Input of a new element In order to insert a new element it is necessary to select, from the list on the left, the type of element to be inserted and then drag it into the upper part on the right and drop it in an appropriate position. On the

basis of the element selected, the tool checks whether the position chosen is compatible or not with the element; if not, the input process is interrupted. If the tool accepts the insert position a dialog box appears requiring all data needed to create the element.

Axis sorting

To perform axis sorting it is sufficient to click on button .

Pressing on Apply button all the changes performed on the elements are saved and shown on graphic window.

How to erase and modify axis elements How to modify elements An advanced CAD, like the one offered by the tool, allows to modify all the elements that make up the

road axis. Remember that it is up to the user to choose among the possible changes, since the changes made might determine incoherent situations from the road normative point of view.

How to erase elements Of course, the elements inserted into an axis can be erased by using the command used to erase any kind of entity. Anyway, the elements must be erased according to a certain order, since the tool does not allow, for example, to erase a horizontal straight if it is connected to a curve; at the same time, it is not possible to erase a curve if it is connected to a clothoid.

It is therefore necessary to erase first the clothoids, then the curves, and finally the horizontal straights.

In order to erase all the current subproject axis elements it is sufficient to select Axis menu, the item

Erase all and then Horizontal alignment elements; it is possible to write DELDATA on the command line:

Insert fixed elements A fixed element has no freedom at all, therefore it is totally defined. The parameters defining a fixed element are the following:

Degree of freedom 0

Radius R=0 to define a straight

R>0 to define a clockwise curve

R<0 to define an anticlockwise curve

In clothoid Only for radius <> 0

Out clothoid Only for radius <> 0

P1, P2 - 2 Passage points Element passage points.

To join two fixed consecutive elements the tool will change automatically clothoid parameters to obtain tangency and bend continuity. In case of reverses the tool will calculate the parameters of the two clothoids keeping the same ratio originally set.

In the window the following information is requested:

Radius: indicate the radius of the element to insert; to insert a straight set 0 as radius value. To insert a clockwise curve, radius value must be positive; vice versa, to insert an anticlockwise curve, radius value must be negative.

Clockwise/Anticlockwise: these options define the curve direction.

Symmetric clothoids: activate this option if out-clothoid parameters are the same as in-clothoid parameters. In this way data are asked only once. A clothoid can be defined by setting one of the following parameters: A Parameter, Length, Shifting. Select from the list the kind of datum desired and insert its value in the numeric field situated below.

Form factor: clothoid form factor, necessary to define hyperclothoids and hypoclothoids.

Passage points: in this area it is possible to modify passage points by entering coordinate values or

indicating the position in the graphic window by using button.

Note: if the clothoid radius or A parameter value is below the minimum value set, and therefore is not

accepted by the policy check, on the corresponding cell the symbol will appear, otherwise symbol will be displayed.

In Property page it is possible to modify display element parameters (layer, colour, line type, thickness).

Press OK to confirm insertion. If a solution can be found to insert the element, this will be inserted in the

graphic window and it will be marked by a red colour.

If no solution can be found, the tool will inform the user about the problem on command line.

Insert rotating elements This kind of element has one degree of freedom; to position this element, we use its condition of

tangency with previous (rotating) or following (rotating previous) element. The parameters defining a rotating or a rotating previous element are the following:

Degrees of freedom 1




In-clothoid Only for radius <> 0

Out-clothoid Only for radius <> 0

Passage point Passage and rotation point of the element.

Preceding/following Element Preceding element for Rotating or following element for Rotating previous on which to keep the condition of

tangency.

A rotating element, therefore, can rotate on the only passage point, so as to satisfy the condition of tangency with the previous element.

The rotating previous element, on the contrary, rotates on the only passage point so as to satisfy the condition of tangency with the subsequent element.

Press OK to confirm the changes made; the tool will re-build the axis according to the new data. If this process cannot be carried out correctly, the tool will inform about this on command line and will restore the axis with the same parameters it had before the modification had taken place.

Intersection points can be modified directly on the graphic window; it is sufficient to select the element to modify and then move the grips that appear after the selection.

Once the grip has been moved, the tool will try to re-build the axis by the same mode explained above.

Conversion of an axis defined by curves into an axis defined by vertexes By this command it is possible to transform completely an axis defined by curves into a corresponding axis defined, with traditional elements, by vertexes.

After performing the command, it is no longer possible to restore the previous situation.

The command can be performed as follows:

Menu Axis > Alignments elements by curve > Convert to axis by vertex

Command line: HE2AXIS

After asking to confirm, the tool will transform the axis defined by curves into a corresponding axis

formed by the traditional elements: horizontal straight, horizontal curve, clothoid.

Sort horizontal alignment elements

The sort of alignment elements is an important phase, which allows to set the alignment start point and to verify that all its elements (horizontal straights, horizontal curves, clothoids) are connected to each other in a proper way, so that all the elaborations made are correct. So, once modification and axis insertion functions have been performed, it is better to carry out this elaboration in order to find possible anomalies in the axis.

The sorting is activated as follows:


Menu Axis : Sort horizontal alignment elements

Command line: SORTPLAN

On CAD command line the following question appears:

**Axis Sort** Indicate start extremity of first axis element:

Indicate the element from which the road axis starts.

If some errors are made the tool indicates the number of elements it has managed to put in order and the number of elements yet to be connected.

Alignment offset

This command allows to create, in a fast way, new alignment elements (horizontal straights, horizontal curves) parallel to the currents axis. It is possible to specify the method to obtain the alignment offset and it is therefore possible to carry out the offset only on one side of the start axis.

The command can be activated through one of the following methods:

Menu Axis > Alignment elements > Alignment offset

Command line: OFFSETA

The tool asks you the following question:

Create Polyline/Alignment/<P>: A

ProSt

The following dialog box appears:

In this dialog box, it is possible to choose first the subproject in which to save the elements obtained as offset.

The different options that can be used to obtain the offset are divided into two different tabs:

Horizontal offset Offset type: gives the possibility to choose the type of horizontal offset to use:

Constant: the same offset distance is kept along all the segment where the offset is performed; specify the distance in Constant offset edit box:

The buttons on the right of the edit box allow to choose whether the offset has to be performed on the left or on the right of the alignment.

Linear: by specifying the start and the end offset it is possible to obtain a linear variation of

the offset distance; indicate the offset at the beginning and at the end of the segment by using Start offset and End offset edit boxes:

The buttons on the right of the edit box allow to choose whether the offset has to be performed on the left or on the right of the alignment.

Second point of segment: Indicate the second of the two points forming the segment crossing the axis and defining the offset start point.

First point of segment: Indicate the first of the two points forming the segment crossing the axis and defining

the offset end point.

Second point of segment: Indicate the second of the two points forming the segment crossing the axis and defining the offset end point.

Press OK to execute the command.

Modify alignment

During the different phases of a project, it is sometimes necessary to modify an alignment complete with profile and sections and the problem is how to avoid restarting from the beginning.

ProSt can manage such situations in a completely automatic way, in fact, the software can update all

data after any project modification. For further details see the chapter dedicated to Dynamic design.

If Dynamic design is not used it is necessary to pay attention to the following concepts:

Before modifying the alignment: it is necessary to transform the sections (Automatic, by Point, by Station) into Free sections; in this way, they will no longer depend on the axis but will be linked to a precise planimetric position;

After modifying the alignment: it is necessary to transform the sections from free to Automatic or by Station; sections will be linked to the axis again and their station will be recalculated;

Following these steps the sections preceding and following the portion of alignment that has been modified are kept unchanged and their station is recalculated.

Check on policy

Through check on policy the tool verifies the congruence of the project parameters of the axis elements with the policy set. The tool provides a very detailed report in which it verifies the congruence of the parameters (lengths, radii, A parameters) of each element (horizontal straights, horizontal curves, clothoids, parabolas) with the policy; in this report the minimum and maximum values to be applied are suggested.

It is possible to select the policy to adopt from Axis menu choosing Axis properties.

Policy check can be activated as follows:

Menu Axis > Policy check

Command line: CHKPOLICY

ProSt

190

A dialog box similar to the following appears:

It is possible to gain access to the same window by Parametric Design, by selecting a horizontal or vertical element in the corresponding column, from menu item Policy.

In the upper side of the window it is possible to select the axis on which to perform the check, while the following options allow to choose on what axis elements to perform the check. It is then possible to perform a check only on the clothoids, or only on the horizontal curves.

In particular, as far as clothoids, it is possible to decide what criterion to apply for the check. As far as

the Italian policy is concerned, it is also possible to decide whether to use, for dynamic rule, the

approximated formula or the exact formula.

Inside the dialog box you will see all the messages representing the result of the check carried out on the axis elements. The list starts showing some information messages and the calculation of the standard parameters used during the checks.

All messages are displayed together with an icon that allows to understand immediately the type of message. The different types of messages displayed are the following:

Policy: minimum and maximum values set by the policy.

Speed: speed used in the check.

Information: message informing about data calculated by the tool.

Error: this message indicates that the project parameters of the element are not congruent

with the policy set.

OK: this message indicates that the project parameters of the element are congruent with the

policy set.

Cross sections in planimetry

After the road axis is set, you can continue the planning phase by positioning the cross sections on the

alignment. Therefore the stations are set, where the sections are situated and it is then possible to calculate terrain longitudinal profile and terrain cross sections.

The sections can be inserted as follows:

Automatic mode: inserts the sections in the alignment main points (extremes of horizontal

straights, tangent points, etc.) and allows to insert sections at a specified interval.

Manual mode: allows to insert manually the sections into the alignment.

Table: from the profile table it is possible to add / modify the station of the sections inserted in the

alignment.

All these methods allow to insert some stations along the axis.

According to the settings chosen in Axis properties, from menu item Labels position, the graphic order of the text indicating station and section number can vary as in the following examples:

Modify sections from planimetry graphic window Sections on axis have now been provided with grips allowing to modify them quickly and easily:

ProSt

192

The first image shows the grips of an automatic section, while the second shows the grips of a section by Point, by Station or Free. The external, arrow-shaped grips allow to stretch the section drawing, while the two internal grips allow to rotate it; the central grip allows to move the section along the axis.

To have the grips displayed it is sufficient to select the sections.

Section types

A typology has been assigned to the sections according to their state and the mode by which they have been inserted.

The possible typologies are the following:

Sections by point (Orange circle with letter P): sections by point are repositioned according

to the horizontal coordinates indicated in the planimetry during the insertion or conversion. For example, if a section by point has 101 as reference point, the tool will always position it on the

projection on axis of point 101.

Sections by station (Yellow circle with letter D):Sections by station are repositioned according to the value of their station. For example, if a section by station has 110 as reference station, the tool will always reposition it on station 110.

Automatic sections (Red circle with letter A): Automatic sections are repositioned, if

possible, according to the rules defined (insertion step, main points, etc.), otherwise they are deleted and reinserted.

Free sections (Green circles with letter L): free sections are not repositioned and are

defined only by their planimetric position.

The typology of each section is represented by the symbols just described in the graphic window.

Moreover, the typology of each section is reported in the table which displays the list of all the sections in Planimetric position page.

Modify cross section typology from graphic window It is possible to change the typology of the cross sections from planimetry graphic window in the

following way:

Select axis where to insert sections: Click on one of the elements that make up the axis in which sections have to be inserted.


The sections can be inserted along the axis in two ways:

Insert cross-section with fixed step: sections are inserted at a fixed distance from each other; set in Insertion step text box the distance desired between sections;

Insert cross-sections only on main points: sections are inserted only on the tangent points of the axis elements.

In case of horizontal curves it is possible to choose into how many parts to subdivide the curve by Horizontal curve subdivision field. Moreover, this option inserts sections also on the intersection areas start and end points.

Insert cross-section on typical section changes: By this option it is possible to insert some cross sections on typical section changes according to intervals defined in the parametric design. Moreover, the tool inserts automatically also some "BIS" sections (1cm far from the cross section on the change) so as to grant a correct volume calculation.

Minimum distance of sections: if both the previous modes have been activated, it is possible to set

the minimum distance between two consecutive sections.

Once the elaboration is finished, the sections will be positioned along the axis and it will be possible to see / modify the stations of the sections on the Table of longitudinal profile.

Manual insertion of cross-sections

How to erase and modify cross-sections in planimetry

Modify To modify a cross-section from the graphic window use the command Modify cross-section properties. The command can be activated in one of the following ways:

Toolbar Objects



ProSt

198

In this window it is possible to modify cross-section data. The station can be inserted manually or its

position on the graphic window can be indicated by button; the tool will calculate the station of the

projection of the point indicated on reference axis.

The position of the cross-section and the recalculation of station can be performed directly in the graphic window, simply by selecting the section and stretching the central grip to a new position.

Cross-sections data can also be modified from the Table of longitudinal profile.

As far as the section drawing in planimetry, the length of the segment that represents the sections can

be controlled from the General tab - Axis properties window. However, it is possible to personalize for

each single section the length of the segment. In fact, by selecting with the mouse the section in planimetry, two grips will appear at the segment extremities; by stretching the two grips, it is possible to lengthen or tighten the segment representing the section in planimetry.

If sections in planimetry are released from the axis then the grips appearing on selection are four: the operating directions of the two external grips are described in the previous paragraph, while the two internal grips are used to control the section rotation; in fact by stretching these two grips the section can change its orientation angle.

On inserting the sections it is possible to check interactively the transversal length on the model or on the survey by opening the window of dynamic sections. See Dynamic sections.

Erase In order to erase one or more sections from planimetry it is sufficient to use the erase command used to

erase any kind of entity; this operation can be also performed from the Table of longitudinal profile.

Modify alignment

During the different phases of a project, it is sometimes necessary to modify an alignment complete with

profile and sections and the problem is how to avoid restarting from the beginning.

ProSt can manage automatically such situations by module A - Advanced design; in fact, by the functions of this module the tool can update all the data every time the project undergoes a modification. See the paragraph describing the Dynamic Design included in ProSt A.

Without the Advanced design module it is necessary to follow the instructions below:

Before modifying the alignment: it is necessary to transform the sections (Automatic, by Point, by Station) into Free sections; in this way, they will no longer depend on the axis but will

be linked to a precise planimetric position;

After modifying the alignment: it is necessary to transform the sections from free to Automatic or by Station; sections will be linked to the axis again and their station will be recalculated;

Following these steps the sections preceding and following the portion of alignment that has been modified are kept unchanged and their station is recalculated.

Speed diagram

A speed diagram is the graphic representation of the design speed alignment according to the road axis station. It is built only according to the horizontal alignment, calculating for each of its elements the

design speed, which must not exceed the limits illustrated above.

It is possible to intervene and modify speed on curve; in case one or more speeds are modified, the diagram is recalculated. In this way it is possible to adapt the diagram to precise existing situations, demanding a speed that is different from the one determined only according to curve radius.

Speed diagrams are used to obtain the wheel base design speed at a certain station, so as to verify the reliability of the project parameters of the elements that form the project.

The command for generating a speed diagram can be activated as follows:

Menu Axis > Checks and diagrams > Speed diagram

Command line: SPDGRAPH

The management of speeds by station has been integrated with the speed diagram generation and control window. The procedure of speed definition has been completely renewed and now allows to

specify easily the speeds also on the intersections. The system allows to specify both stretch start and end station or just one of them; in the points where an axis exits the intersection it is therefore possible to set the stretch start station and the corresponding speed, while in the point where an axis enters the intersection it is possible to set only the end station. According to such information, and to the

acceleration coefficient, which can be set by the user, the software will modify the speed diagram.

Speeds by station

Speeds by station can be inserted in Speeds by station by activating the option Speeds by station.

It is possible to insert the speeds in the table in the following ways:

Start speed: it is the situation in which the speed at the beginning of a stretch is known; it can be, for example, the exit of an axis from an intersection. In this case it is sufficient to set the start station and the two speeds, the minimum and the maximum, which, in most cases, have the same value.

Final speed: it is the situation in which the speed at the end of a stretch is known; it can be, for

example, the entry of an axis into an intersection. In this case it is sufficient to set the final station and the two speeds, the minimum and the maximum, which, in most cases, have the same value.

Speed by station:

it is the situation in which you want to change the project minimum and maximum speed for a segment of the axis. In this case both minimum and maximum stations have to be set, as well as minimum and maximum speed.

Speed by curve

As far as these checks, the table reports, for each curve, radius value, project speed and a spot whose colour depends on the result of the check: a red spot indicates that the check is not fulfilled, a yellow spot indicates that the result is acceptable, a green spot indicates that the check is completely fulfilled.

By using , , buttons it is possible to modify the speeds on each curve or recalculate the

project speed in the whole diagram or only on the curves selected in the table.

check. The page displays the result of the diagram speed check according to the policy. As far as the italian policy the following checks are performed:

The software checks the speed difference in passing from the maximum speed to a lower speed.

The software checks the difference between two consecutive curves

the software checks whether transition distance is shorter than recognition distance and sight distance; as far as the sight distance check it is necessary to have previously carried out the sight

check. It is then possible to select from the list Reference sight distance the process to use to perform the check.

The procedure allows to perform the calculation of the roadway rotations and widenings in the circular curves of the alignment. For each curve in the alignment the tool asks you to indicate the amount of heavy traffic in order to calculate the widening as well as the minimum and maximum speed in order to calculate the rotation of the roadway. In case there is no clothoid the tool needs two lengths, in and out of the curve, on which to distribute the widening and the rotation.

The table of rotations and widenings is activated in one of the following ways:

Menu Axis > Superelevation and widening

Command line: SUPERELEV

If the table is activated for the first time, some fields are compiled automatically, with the values set in Axis properties - Calculation tab dialog box according to the policy applied.

ProSt

210

The following table appears:

All data displayed in the dialog box belong to the subproject selected in Subproject list box. In order to display and modify data belonging to another subproject it is sufficient to select it in the already

mentioned list box.

Calculation page

Each line of the table in Calculation tab displays the data of the curve present in the alignment. For every

curve the following data are reported:

Curve Radius. Not modifiable. RO.Tan.In. Equivalent length in the horizontal straight of entrance. If there is a clothoid at the beginning

of the curve, you can't edit this value. RO.Cur.In. Equivalent length in the curve of entrance. If there is a clothoid at the beginning of the curve, you can't edit this value.

RO.Cur.Out. Equivalent length in the exit curve. If there is a clothoid after the curve, you can't edit this value. RO.Tan.Out. Equivalent length in the exit horizontal straight. If there is a clothoid after the curve, you can't edit this value. % Heav.Traf. amount of heavy traffic. Used to calculate the widening. SpdMin. Project minimum speed.

SpdMax. Project maximum speed. Widening. Widening value per lane. Superelevation. Superelevation maximum value calculated in curve.

According to the policy applied, some of the previously listed fields may not be present.

Equivalent lengths The tool asks to set equivalent lengths in case clothoids, that fillet the horizontal straights with the curve, have not been inserted. Through the equivalent length, it is possible to simulate the presence of a clothoid or, in general, of a transition fillet along which to allocate the cross slope difference existing between the horizontal straight and the curve. The equivalent length is then a distance which can be associated to the horizontal straight or to the curve or to both. Along the

ProSt

211

distance, the cross slope gradually changes from the value associated to the horizontal straight to the value associated to the curve.

Equivalent length value can be inserted manually or calculated by the tool. Select the rows in the table (curves) for which to calculate equivalent length and then press Equivalent length button; the following window will appear:

Equivalent length can be calculated by a formula or it can be a fixed value assigned by the designer. The formula used allows to obtain an equivalent length, which grants a certain

longitudinal slope of the edge on passing from superelevation on horizontal straight to elevation on curve.

The longitudinal slope to be granted can be minimum longitudinal slope, maximum longitudinal slope or also a value set by the designer.

Once the equivalent length has been calculated, it is possible to decide how it must be distributed on two elements, horizontal straight and curve; the window allows to set a distribution rate for the

amount of equivalent length to report on the horizontal straight and the amount to report on curve.

Finally, it is possible to set a minimum length, in which the straight situated between two curves keeps the camber; therefore, the tool will grant that a straight between two curves has at least a segment with camber and will shift the excess of equivalent length onto the two curves.

By pressing OK button the tool will apply the values calculated to the curves selected.

By inserting or modifying the data concerning the amount of heavy traffic and of project speeds, the

curve superelevation and widening values are immediately calculated.

In the lower part of the window there is a display that shows the planimetric line of the axis elements and reports the direction of each curve (right/left); by changing the data of the equivalent lengths it is possible to see immediately the resulting situation which is automatically reported on the display. This possibility allows the user to study which is the best value of equivalent length to be adopted comparing it with the previous and the following curves. Besides, you can see how the display changes when you select another row; the display, with the same zoom factor, will show the curve corresponding to the row

selected.

By using buttons , , , you can respectively reduce the zoom factor, increase the zoom factor,

Superelevation tab

Lateral menu Superelevation is subdivided into two sections, by which it is possible to manage

superelevations by curve or by station.

Manage superelevations by curve

In Superelevation tab there is a table containing six rows for each curve; the six rows represent the six tipical situations that you can meet along a curve:

In - Normal. Start point of the curve. The start point is determined by the presence of a clothoid

or by the setting of an equivalent length in Calculation tab. In this point the cross slope coincides with the slope in a rectilinear direction.

In - Reverse. It represents the point where the two cross slopes (right and left with reference to

the superelevation point) are equal but opposite.

In - Full. Point representing the maximum slope calculated: it can be the point where the clothoid or the equivalent length end.

Out - Full. Last point representing the maximum slope calculated to be kept. It can be the point

where the exit clothoid or the equivalent length start.

Out - Reverse. It represents the point where the two cross slopes (right and left with reference to the superelevation point) are equal but opposite.

Out - Normal. Point where the curve ends: this point can be determined by the end of the clothoid or by the end of the equivalent length set in the Calculation tab. In this point the cross slope coincides with the slope in a rectilinear direction.

In the lower part of the window there is a display that shows the sequence of the axis elements and

reports the line of the right and left edges. By modifying the data of the table, the display will be

automatically updated to the new situation; in this way, the user will be allowed to remodel the edges where necessary, having the possibility to intervene on any parameter. Besides, you can see how the display changes when you select another row; the display, with the same zoom factor, will show the station corresponding to the row selected.

Manage superelevations by station

In this management a table is available, reporting all the stations with a change in superelevation. The table can either be filled by the designer, or be the result of settings performed in Calculation table or in the table of Superelevation by curve.

The table reports the following data:

Station: station on axis.

Left slope: left transversal slope.

Right slope: right transversal slope.

Dl left: longitudinal slope of left edge.

Dl right: longitudinal slope of right edge.

Dl min: minimum longitudinal slope set by policy.

Widenings tab

Lateral menu Widening is subdivided into two parts, allowing to manage widening by curve or by

station.

Widening by curve

A table is also present in Widenings tab and for every curve there are four rows; these ones represent

the four tipical situations that you can meet along the curve:

In - Normal. Start point of the curve. The start point is determined by the presence of a clothoid or by the setting of an equivalent length in Calculation tab. In this point the widening is null.

In - Full. Point of maximum widening. It can be the point where the clothoid or the equivalent length end.

Out - Full. Last point representing the maximum widening calculated to be kept: it can be the

point where the out-clothoid or the set equivalent length begin.

Out - Normal. End point of the curve. The end point coincides with the end of the clothoid or with the end of the equivalent length set in Calculation tab. In this specific point the cross slope of the curve coincides with the slope in a rectilinear direction.

In the lower part of the window there is a display that shows the sequence of the axis elements and reports the widening of right and left edges. By modifying the data of the table, the display will be automatically updated to the new situation; in this way, the user will be allowed to remodel the widenings

where necessary, having the possibility to intervene on any parameter. Besides, you can see how the display changes when you select another row; the display, with the same zoom factor, will show the station corresponding to the row selected.

Widening by station


Station: station on axis.

Left widening: left widening.

Right widening: right widening.

In order to assign to sections on the road axis the values present in the three tables, it is necessary to press Set calculated values button. Once the procedure has been performed, in the Table of longitudinal profile, Superelevations and widenings you will see how the calculated values have been assigned to sections.

Note. The calculation of superelevation and widening must be carried out after the sections have been

positioned in planimetry and before the road section has been inserted in the cross sections. In fact, the insertion of the typical section takes into account the already calculated values of superelevation and widening. Therefore, if the values of superelevation and widening have been modified it is then necessary

to reinsert the typical section.

Button Default allows to restore all default values of all the curves, while button Curve default restores all default values of the current curve only.

Geometry annotation

By geometry annotation it is possible to obtain the automatic dimensioning of the whole alignment elements. The generation of a geometry annotation can be completely customized and offers the opportunity to create different dimensioning styles. Several options allow to obtain a different

dimensioning, according to one's needs: for each kind of dimensioning it is possible to decide what data

to dimension, position, text style, label name, etc.

The styles created will make up a library that can be used in different projects.

Annotation styles

An annotation style is made up of a set of standard typologies, each one containing properties the user

can modify; some typologies exist, for the geometry annotation of the alignment vertexes, for the dimensioning of the single elements, etc.

The window for the management of geometry annotation styles can be activated by the following command:

Menu Axis > Geometry Annotation > Creation

Command line: GEOMANNSTYLE

The top of the window displays the commands for the management of styles. A check list displays a list of

Remove an annotation from the current style

By button it is possible to remove from the current style the annotation typology selected.

Types of annotations available The types of annotations available are the following:

Stations: this annotation can report a symbol and the corresponding text at predefined distance intervals along the axis. It indicates kilometric and hectometric points along the alignment; the

dimensioning allows to define the main interval (kilometric) and a secondary interval, both with a specific symbol and text.

ProSt

218

Relative maximum and minimum points: this annotation reports some symbols along the alignment in the relative minimum and maximum points deduced from the axis vertical

alignment.

Vertexes table: by this annotation it is possible to obtain tables reporting the coordinates, and not only the coordinates, of the alignment vertexes. Several options make it possible to check the position of the tables, the size and data to be displayed.

Curve tables:this annotation can generate the tables referred to the circular curves in the

alignment; also in this case several options make it possible to meet every dimensioning need.

Railway curve tables: also this annotation refers to the circular curves but it also includes

information which is typical of the railway projects as speed, superelevation, length of parabolic curves, shifting, etc.

Horizontal straights annotation: this very simple annotation on horizontal straights reports

their length.

Curves annotation: this annotation can report such information as radius, angle, length of every curve.

Clothoids annotation: clothoids annotation generates a drawing that reports the clothoid main

information, such as parameter A, length, length of long and short tangent, etc.

Parabolas annotation: as with clothoids, this annotation can report the parabola main data.

Tangent points: on the elements tangent points this annotation reports such information as station and element reference parameter (radius for the curves, A parameter for the clothoids).

Vertical curves vertexes: this annotation reports along the axis the information obtained from

the vertical design; it reports grade line vertexes and vertical curves tangent points.

The styles are saved in the tool Styles folder and are common to all the projects.

Planimetry of project

A planimetry of project is the planimetric representation of a road, complete of project elements: roadway, roadsides, sideslopes, ditches, walls, etc.; a planimetry of project allows to study planimetrically the position and the shape of the different elements in the cross sections.

The command generating the planimetry of project allows to obtain a 3D drawing of lines and polylines but also the 3D model of the road the existing terrain model can be joined to.

The ways to generate a planimetry of project are the following:

From cross-sections: from complete cross sections it is possible to obtain the planimetry of

project of a road. In this case, the result obtained depends completely on the content of the cross sections; any element contained in the cross sections can be projected on the planimetry.

From geometric section properties (Parametric design): in this case the planimetry of

project is obtained directly by inserting along the axis one or more typical sections; this mode does not require the project to have been developed completely, as far as cross sections: it just

ProSt

221

needs a horizontal alignment and a corresponding vertical alignment. The result obtained does not depend on the cross sections, so it is up to the user to make sure a correspondence exists between the planimetry of project obtained in this way and the content of the cross sections.

Pros and cons of both solutions can be summed up in the following table:

Planimetry of project Pros Cons

From cross sections

The result depends on the content of the cross sections; even after a manual modification of cross sections, this modification can appear in the planimetry of project.

The quality of the result could be imperfect, mostly when the shape of sections changes on passing from a section to the other (ex. cut and fill sections).

From geometric section properties

The quality of the result and of project model is superior, mostly when the

shape of sections changes on passing from a section to the other.

The result might therefore not reflect exactly the content of the cross

sections. If manual modifications are made on the cross sections, these modifications will not appear in the

planimetry of project. .

Planimetry of project from cross sections The project planimetry is generated as follows:

Minimum slope\Maximum slope: in these two edit boxes you can indicate the slope limits necessary to carry out the automatic drawing of slope-hatches. The tool checks each segment and if

the slope is within the two limits, in that segment the slope-hatch drawings will be activated. To display slope-hatches it is necessary that you select the section element Slope-hatch property by using Section's elements settings button.

Apply defined hatches: if this option is active the tool completes the planimetry of project

drawing with a hatches model or with a solid color; the application of hatches or colors is carried out on single section elements. For each element that determines the planimetry of project, it is then possible to decide whether to fill in its surface with a hatches model or a solid color. Use Section's elements settings button to assign hatching and color to each element.

Erase previous elaborations: if this option is active, the tool automatically cancels all the results obtained by the previous elaborations.

Planimetry of project from geometric section properties (Parametric design): The project planimetry is generated as follows:

Menu Axis > Project planimetry > Creation...

Command line: PROJPLAN


To generate a planimetry of project from typical sections activate the option Creation from cross sections.

Generation mode: Three different modes to generate the planimetry of project are available. They differ as far as generation speed and level of accuracy of the result obtained. According to the design phase being carried out it is possible to choose the most convenient generation mode (example: fast and less accurate during the design phase, slow but accurate when returning the final results).

No interpolation: By this mode the tool calculates for each point in the axis a typical section and obtains automatically the crossing points between cut and fill. This mode returns the most accurate result, but it also requires more time to be carried out. To be used at the end of the project for the

final drawings.

Interpolation on transition zones. By this mode the tool calculates for each point in the axis a typical section and interpolates the typical sections in the crossing points between cut and fill, not

calculating the exact crossing point. This mode is always accurate and it is a little faster than the one with no interpolation.

ProSt

228

Interpolation by typical sections (Suggested mode). By this mode the tool calculates the typical sections only on generation main points and interpolates the typical sections of the axis intermediate points. This mode is the fastest one but it is also the one that gives the less accurate results. To be used during the design phase.

Maximum step for model creation: this is the maximum distance used by the tool between a typical

section and the following one. The tool automatically inserts some typical sections in the critic points of the alignment: element tangent points, passage points between cut and fill. On curvilinear elements (clothoids, parabolas, horizontal curves) the distance between a typical section and the following one is such as to make it possible to obtain an optimal representation of the curve; this is true also for vertical curves.

Generation main points: this group of options allows to define on what points, besides the ones defined by horizontal and vertical elements, to calculate the typical sections so as to increase the accuracy of the

planimetry of project. Generation main points are the following:

Cut/fill passage points: This option integrates the crossing points between cut and fill in the alignment axis.

Superelevation and widening vertexes: This option integrates the transversal slope change points and the widening points calculated for the axis.

Cross sections: This option integrates the points near the sections stations along the alignment.

Planimetry and profile polylines: This option integrates the projection of the axis planimetry and profile polyline vertexes.

Axis variables: This option integrates the points near the stations of the axis variables situated in the axis.

The tool checks each segment and if the slope is within the two limits, in that segment the slope-hatch drawings will be activated. To display slope-hatches it is necessary that you select the section element Slope-hatch property by using Settings button.

Apply defined hatches: if this option is active the tool completes the planimetry of project drawing with a hatches model or with a solid color; the application of hatches or colors is carried out

on single section elements. For each element that determines the planimetry of project, it is then

possible to decide whether to fill in its surface with a hatches model or a solid color. Use Settings button to assign hatching and color to each element.

Erase previous elaborations: if this option is active, the tool automatically cancels all the results obtained by the previous elaborations.

Use all section elements: the planimetry of project is generated by using all the sections elements

available, not only those specified by the button Set transversal elements.

231

In this phase the parameters are required, for the generation of the road 3D mathematical model.

Reference terrain model: specify what survey subproject represents the present situation (terrain).

Create mathematical model of the project: : this option specifies that you want to obtain the calculation of the project mathematical model. 3D faces will be created, merging some sections elements specified by Section elements settings button.

Destination subproject: select the survey subproject that will contain modelling areas. To create a new subproject see Create subprojects

Check model intersections: this option is active only when you want to generate a model of the planimetry of project but not to obtain its drawing. By activating this option the tool checks the presence of intersections between the different 3D faces of the model and corrects them; this utility becomes very important with very narrow curves, such as hairpins. In these cases uphill-sections sideslopes might intersect downhill-sections sideslopes; thanks to this option the tool makes it

possible to solve this kind of problems and return a precise model.

Merge with terrain digital model: by activating this option it is possible to obtain a final model, complete with terrain model triangles in the area out of the project. It is therefore possible to obtain a model of the project inserted in the model representing the current situation. The tool will delete automatically the terrain triangles situated in the project area; it is possible to specify the elements that form the external part of the project model by Section elements settings button.

Remove previous results: by activating this option the results obtained with previous elaborations are automatically deleted.

Press Generate button to start the creation of the Planimetry of project according to given settings.

It is possible to interrupt the drawing of the planimetry of project and/or the tridimensional model calculation in some segments of the road, for example for the presence of a viaduct, a tunnel or else.

Section's elements settings Through button Settings you can open a dialog box that allows to specify, for each section elements, different properties determining the method with which the planimetry of project and the tridimensional model calculation of the road can be performed:

ProSt

232

In the upper part of the window a table reports the codes of all the section elements defined in the table of Section codes. For each element it is possible to set the following properties:

Plan: this property can assume the following values:

None: the element is not considered for the generation of the planimetry of project.

Top line: the element is considered for the generation of the planimetry of project, but the tool will

use only the segments of the element that are not "covered" by other segments; only the visible part of the element will be used. It is better to activate this property only for the elements situated on top of the section, not for those placed under other elements.

Complete: the element is considered for the generation of the planimetry of project in a complete way, so any of its segments will be reported in the planimetry of project. Activate this option to export integrally into the planimetry of project such elements as guard-rails, fences, etc.

Slope hatches: activate this option if you want to display the slope hatches drawing for the

corresponding element. The slope hatches drawing also depends on the minimum and maximum slope values that can be set in the main dialog box.

Hatch: in this column it is possible to specify whether in the planimetry of project the element must be filled with a solid color or with a hatch model that you can choose among those available. See How to load hatch models. This operation can be performed only if, in the main dialog box, the option Apply defined hatches is active.

Angle: start angle for hatch drawing.

Scale: scale factor to be applied to the hatch model.

Color: color to display the hatches with or full color to use. This color is used if Slope hatches option has been activated and the slope of the segment to represent is negative; otherwise, a color will be used, that has been set in Color 2 property.

Color 2: color to display the hatches with or full color to use. This color is used if Slope hatches option has been activated and the segment to represent is positive; otherwise, the color will be used, that has

been set in Color property.

Note. By setting two different colors in Color and Color 2 properties for the element that defines the slope in the cross-sections it is possible to obtain a different colour for cut slopes and fill slopes respectively.

How to erase a project planimetry

In order to erase one or more elements of the project planimetry from the graphic CAD windows it is sufficient to use the erase command used to erase any kind of entity.

To delete the current subproject project planimetry follow one of the following instructions:

Menu: Axis > Erase all > Project planimetry



Erase data Alignment elements/Geometry annotation/Planimetry of project/planimetry poLylines/Cancel/<L>: Choose Planimetry of project and press ENTER

Break contour lines on planimetry of project

After drawing the planimetry of project it could be convenient to obtain a drawing including the

planimetry of project along with the digital model contour lines; to have the contour lines broken on the planimetry of project follow one of the modes illustrated below:

Menu: Axis > Project planimetry > Break contourlines

Command line: BREAKCONT

ProSt

233

The tool will start an elaboration which will allow to see the planimetry of project with no contour lines passing below it.

To restore the original contour lines choose among the following commands:

Menu: Axis > Project planimetry > Restore contourlines

Command line: RESTORECONT

To pass from the display of the broken contour lines to the display of the complete curves it is possible to activate the filter from Axis properties.

Alignment polylines

Planimetry polylines are particular polylines marked by a code. The code is necessary to recognize them and then enable the software work in different ways, according to the polyline it recognizes. Obtaining

the polylines as offsets from axis makes it possible, for example, to build quickly the planimetric obstructions of roads, roadsides, ditches, etc.By using merge and fillet commands, together with the other CAD commands, it is also possible to create road arrangement projects.

Moreover, some commands are available for the quick generation of planimetry polylines which are particularly useful for the generation of edge lines.

ProSt Premium includes a command allowing to extract a terrain and project profile from a planimetry polyline; the project elevations are the elevations of polyline vertexes, while terrain elevations are

automatically calculated by the digital terrain model. The command can be used in generating terrain/project profiles corresponding to the zones in which such works as walls, shoulders, etc. must be inserted; according to the planimetry polyline representing the road edge it is possible to generate the corresponding profile to use to project the typical element. See Extract planimetry polyline profile.

Again in ProSt Premium It is possible to define some planimetry polylines representing the sections cut lines. On inserting the typical sections and on generating the project planimetry the tool can consider the

cut lines and at the same time cut the exceeding part. This function is very useful in designing interchanges ramps, since it allows to define in the planimetry the cut line that determines the automatic elimination of overlapping areas between the main axis and the ramp. See Cut polylines.

The cross sections in the intersection area are recalculated by the command generating the project planimetry.

ProSt Premium users can take advantage from some commands allowing to create such planimetry polylines as horizontal curves between the edges of two axes. Besides being useful from a planimetric

point of view, planimetry polylines can be used for other elaborations inside the longitudinal profile and cross sections modules.

Use of planimetry polylines in profile In the longitudinal profile it is possible to use planimetry polylines as references for the creation of profile

polylines: the profile polyline is calculated by considering the projection of the planimetry polyline on the axis the profile refers to (ProSt Premium). Otherwise it is possible to use the planimetry polylines to obtain, in profile, symbols indicating the intersection point between the polyline and the axis the profile refers to (ProSt Premium).

Use of planimetry polylines in sections In the cross sections planimetry polylines can be used to give a planimetric reference to typical sections;

in fact it is possible to create typical sections which can autosize (in width) according to the distance between the axis and the planimetry polyline.

Example:

Suppose we have to design a road in which the roadway width is not constant because of the presence of stop areas, parkings or else; of course the sections will have to represent such situations, so there will

have to be some cross sections in which the width of the typical section will be different according to the

ProSt

234

section stations. If no automatism is available, it is up to the designer to assign each section the correct sizes previously measured. If we could draw some 2D polylines representing the position of the two edges, the left one and the right one, and the typical section of the sections could interpret the presence of such polylines and automatically widen or narrow, then no manual operation would be necessary.

In cross sections, planimetry polylines can be used to provide the typical sections with a planimetric

reference; it is in fact possible to create typical sections which can autosize (in width) according to the distance between the axis and the planimetry polyline.

Planimetry polylines can deal effectively with such situations: in fact, it will be sufficient to create two polylines, one on the right and one on the left, with a different code, representing the position of the two edges; then, a typical section will have to be created, whose two points will be associated to the codes of the two polylines. On inserting the typical section the tool will search for the polyline associated to the point, calculate its distance from axis and change the sizes of the

typical section that will be inserted.

As in the profile, also in the sections it is possible to obtain some references from the intersection between the section and planimetry polylines (ProSt Premium); in this way it is possible to know, in the section, where those elements represented as planimetry polylines pass by.

Definition of alignment polylines codes When you operate with alignment polylines, the first thing to do is to define the polyline code to be used. However, it is always possible to change the code of a polyline already created: change alignment polyline code.

Alignment polylines can be also obtained by the transformation of drawing polylines and vice versa; for example it is possible to import a DXF file and then to transform drawing polylines into alignment

polylines without having to insert them again. See Entities transformation.

Definition of alignment polyline codes

Since each polyline is associated to a code, there is a table where you can set the codes that can be

assigned to polylines. Each code is also associated to a layer on which the polyline having that code will be drawn.

The codes table is activated in one of the following ways :

Menu Axis > Alignment polyline > Polyline codes

Command line: CODPLAN


The tool asks to specify the following settings:

Code: choose polyline code;

Description. It is possible to assign an extended description to each code;

Section flag. If a flag is present in the typical section, specify the number to refer to, so that, by choosing to generate the planimetry of project from section flags, or by using the command of polyline

generation from section flag, the tool will automatically create a polyline with the code specified in this table.

Layer. Layer to which the polylines with the corresponding code will be assigned.

Alignment offset

By this command, the user can rapidly create polylines parallel to the current alignment. It is possible to specify both the methods by which you can obtain the horizontal offset (planimetric) and the methods by which to obtain the vertical offset; besides, the tool allows to perform the offset on only a part of the start alignment. To carry out a vertical offset, the tool uses as reference elevations those provided by the grade lines and by the vertical curves present in the profile or those defined by a tridimensional

alignment polyline.

The command can be activated through one of the methods below:

Menu Axis > Alignment polyline > Alignment offset

Command line: OFFSETA


Create Polyline/Alignment/<P>: P

ProSt

245


In the dialog box you can first choose the code to be assigned to the polyline to be created.

All the options through which it is possible to obtain the offset are divided into three different tabs:

Horizontal offset Reference for offset distance : It is possible to choose the axis or the alignment polyline as a reference on which to apply the offset distance:

Current axis: the offset distance is applied on current axis.

Alignment polyline: the offset distance is applied starting from an alignment polyline; the current axis defines the offset direction while the polyline defines the point from which to apply the offset distance keeping the direction set by the axis. The offset obtained in this way is different from the offset calculated from the polyline.

ProSt

246

It is possible to set the maximum distance inside which you can find the intersection between the line perpendicular to the axis and the polyline. Finally, you can specify the Horizontal

straight feed step that allows to create offset points located each one at a fixed distance in horizontal straights.

Offset type: this option allows to choose the type of Horizontal offset to be used:

Constant: through this option you can keep the same offset distance for the segment on which the offset is performed; indicate the distance in Constant offset edit box:

Buttons on the right of the edit box allow to decide whether the offset must be performed on the left or on the right of the axis.

Linear:through this option you can obtain a linear variation of the offset distance by

specifying the start and the end offset; indicate the offset at the beginning and at the end of the segment by using Start offset and End offset edit boxes:

Buttons on the right of the edit box allow to decide whether the offset must be performed on the left or on the right of the axis.

Axis: the offset distance is calculated by the tool according to the distance of each point from another reference axis. In this way, it is necessary to obtain a polyline that lies, in a planimetric point of view, on a reference axis but depends from the current axis in an

altimetric point of view; this polyline can be used effectively in the longitudinal profile, through the projection of alignment polylines, in order to know the vertical alignment of a

ProSt

247

flanked-axis. According to the flanked-axis vertical alignment you can set the new axis grade lines and vertical curves.

This elaboration can be performed in three ways:

Direct projection: a polyline is generated on the secondary axis with elevations depending completely on the elevations and the transversal slopes of the main axis.

To use this mode it is sufficient to set in Subproject check list the axis to use as reference for distance calculation.

Projection with one polyline: a polyline is generated on the secondary axis, with elevations calculated according to elevations and slopes of main axis, as long as it

meets a planimetry polyline; on the contrary, from this point on, the secondary axis transversal slopes will be considered.

To use this mode it is necessary to set in Subproject check box the axis on which the projection is made, activate the option Change slope - First polyline and set the code of of the planimetry polyline determining the boundary between the application of main axis slopes and secondary axis slopes.

Projection with two polylines: three projections are performed,: the first by

considering the elevations and the slopes of the main axis on the first planimetry polyline; the second projection is carried out between the first and the second

planimetry polyline, with a slope set by the user, the third projection is performed between the second planimetry polyline and the secondary axis; in this case, secondary axis slopes are considered. This command is the solution to problems concerning the design of ramps in the cuspid area.

To use this mode it is necessary to set in Subproject check box the axis on which the projection is made, activate the options Change slope - First polyline,Change slope

ProSt

248

- Second polyline and set the code of the two planimetry polylines determining the boundary between the application of main axis slopes and secondary axis slopes.

In Subproject edit box specify the axis to be used as a reference for the calculation of the

distance; in Maximum search distance edit box it is possible to specify the maximum distance value to which refer for the creation of the polyline. In this way, if the distance

between the current axis and the reference axis is higher than the value set, the polyline is interrupted. Finally, you can specify the Horizontal straight feed step that allows to create offset points located each one at a fixed distance in horizontal straights.

Vertical offset

Use elevation: if you activate this option you can obtain tridimensional alignment polylines; infact,

the polyline vertex elevation can be calculated by using, as start elevation, the elevation obtained from the grade lines and vertical curves present in the longitudinal profile or by using tridimensional alignment polyline elevations.

Reference for elevations: it is possible to decide whether the reference elevations must be taken from the current axis grade lines and vertical curves or from an alignment polyline:

Current axis project elevations: reference elevations are obtained from the current axis grade lines and vertical curves.

ProSt

249

Planimetry polyline: reference elevations are obtained from a tridimensional alignment polyline. With this option it is possible to calculate, for instace, a tridimensional polyline by using, instead of the axis, another alignement polyline as altimetric reference; the following drawing represents this situation from the section point of view:

Offset type: after you have activated the previous option, you can decide how to calculate the polyline vertex elevations.

Use calculated superelevation: with this option, you can use the superelevations calculated with the command Calculation of superelevations and widenings. Then, the transversal slope to be used is calculated point by point and is applied to the offset distance,

having the reference elevation, chosen in the previous step, as start elevation. With this option it is then possible to obtain, for example, the 3D polylines of the road edges shape.

Constant transversal slope: this option is similar to the previous one but for the fact that it applies a constant slope on the whole segment where the offset is performed. Indicate the slope value in Transversal slope dialog box:

The two buttons on the right allow to choose whether the slope must be negative or positive.

Constant vertical offset: with this option you have to apply a difference of elevation to the

reference elevation. For example, if you want to obtain a 3D polyline whose elevations must be two meters lower than the reference elevations, then it is sufficient to set value 2 in Vertical offset edit box:

The two buttons on the right allow to choose whether the difference of elevation must be negative or positive.

Start and End

It is possible to carry out the offset on the whole axis or on part of it. The tool offers the following options:

Start and End station: with this option it is necessary to specify the Start and End station so defining the part where the offset has to be performed. Indicate the two stations inside the edit boxes.

Start and End section: with this option it is necessary to specify the Start and End section so defining the part where the offset has to be performed. By using the buttons on the right

of the edit boxes it is possible to choose the sections in the list.

Select start element:

Indicate the element from where the offset has to start.

Select end element: Indicate the element where the offset has to end.

Cursor position: the tool asks to indicate graphically the two points defining the part where the offset has to be performed. For each point it is necessary to indicate a segment crossing the axis.

Second point of segment: Indicate the second of the two points forming the segment that crosses the axis and defines the end point of the offset.


Offset from another polyline

This command allows to create a new polyline which is the offset of the polyline taken as reference. The offset can be either horizontal or vertical according to different ways. The command can be activated by one of the methods listed below:

Menu Axis > Alignment polyline > Polyline offset

Command line: OFFSETP


In the dialog box you can first choose the code to be assigned to the polyline to be created.

All the options through which it is possible to obtain the offset are divided into two different tabs:

Horizontal offset Offset type: allows to choose the horizontal offset type to be used:

Constant: through this option you can keep the same offset distance for the segment on

which the offset is performed; indicate the distance in Constant offset edit box:

Buttons on the right of the edit box allow to decide whether the offset must be performed on

the left or on the right of the axis.

Linear:through this option you can obtain a linear variation of the offset distance by specifying the start and the end offset; indicate the offset at the beginning and at the end of the segment by using Start offset and End offset edit boxes:

Buttons on the right of the edit box allow to decide whether the offset must be performed on the left or on the right of the reference polyline.

Vertical offset

Set elevation: with this option it is possible to use the vertex elevations of the reference polyline in order to obtain a tridimensional polyline.

Offset type: this option allows to decide how to calculate the polyline vertex elevations.

Constant transversal slope: this option allows to calculate the vertex elevations of the new polyline by applying a constant transversal slope to the offset distance. Indicate the value of the slope in Transversal slope edit box:

The two buttons on the right of the edit box allow to decide whether the slope must be negative or positive.

Constant vertical offset: with this option you will apply an elevation difference to the reference polyline vertexes. For example, if you want to obtain a 3D polyline whose elevations are 2 meters lower than those of the reference polyline, then it is sufficient to set

value 2 in Vertical offset edit box:

The two buttons on the right of the edit box allow to decide whether the elevation difference must be negative or positive.

Create polyline from section flags

In the cross sections it is possible to insert a flag in order to identify particular points such as edge points

and ditch points, wall points, etc. Identifying such points in the cross sections is very important, so to obtain automatically:

the longitudinal profile derived from these points;

the planimetric line of the elements they represent.

It is therefore possible to obtain automatically a polyline representing, both in planimetric and longitudinal profile view, ditches, walls etc.

Warning. The command for generating the Planimetry of project allows to generate automatically from section flags also planimetry and profile polylines.

After inserting the flags in the section points it is possible to obtain automatically the alignment polyline

by activating the command in one of the following ways:

Menu Axis > Alignment polyline > From flag of sections

Command line: PLANFLAG


The first data that the tool requires is the code of the polyline to be created. Select the code from the Polyline code list box. Polylines codes can be set in the Polyline codes table.

In this dialog box you have to set the flag number, to be searched in the cross sections, in Flag value to

be found edit box. It is then possible to decide whether to search the flag in the whole section or only on the left/right.

Pressing Process button, the tool will draw a new polyline representing the planimetric line of the points identified by the cross-section flags.

Filleting polylines

Fillet polylines procedure allows to fillet two polylines in a fast way. For example, this command can be used to obtain median strips. In fact, from the offset of the axis forming the crossing several fillet polylines are created allowing to obtain rapidly median strips or other elements.

The command is activated through one of the methods listed below:

Menu Axis > Alignment polyline > Fillet polyline

Command line: FILLETP

ProSt

The following questions appear:

Select first polyline: Select second polyline: Radius:

A new polyline is created which includes the two starting polylines that, if necessary, can be erased.

Note. When you select the polylines, remember to indicate the point which is the nearest to the point where the fillet will be inserted.

Note. Not in all the cases the tool is able to calculate a fillet joining the two polylines.

Joining polylines

This command allows to create one polyline starting from a set of polylines which share the same ends.


Menu Axis > Alignment polyline > Join polyline

Command line: JOINP


Select polyline: Select...

Select the first polyline and then the polylines to join.

Exctract planimetry polyline profile

By this command it is possible to extract a terrain and project profile from a planimetry polyline; project elevations are the elevations of polyline vertexes, while terrain elevations are automatically calculated

from the digital terrain model.

The command can be used in generating the terrain/project profiles corresponding to the areas in which to insert such elements as walls, shoulders etc; according to the planimetry polyline representing the road edge it is possible to generate the corresponding profile to be used to design the typical element.


Menu Axis > Alignment polyline > Extract polyline profile

Command line: EDGEPROF

ProSt

255

Once the planimetry polyline from which to obtain the profile has been indicated, the following window will appear:

The procedure transforms the polyline into an axis that can be saved in a new subproject or in an existing subproject, as long as it is empty. Along the axis some sections are positioned, at a distance that can be set by the user.

The profile that will be generated will have as the sections project elevations the elevations interpolated from the polyline and as terrain elevations the result of the interpolation of the polyline on the reference terrain model.

Axis subproject: by this group of options it is possible to create the polyline profile on a new axis subproject or on an existing subproject, as long as it is empty.

Reference axis: represents the axis that will be used as reference in case the option On reference

axis is activated. By this option sections are inserted automatically and the reference distance considered

is the one calculated on the reference axis, not on the polyline.

Cross-section step: insertion distance between sections.

On reference axis: by activating this option the tool inserts the sections calculating the distance not on the polyline but on the reference axis set. In this way it is possible to obtain a profile where sections have a fixed step referred to the main axis. This possibility, along with the option that allows to obtain the profile dimensioning as to a reference axis, allows to generate longitudinal profiles of lateral elements (e.g. walls) with a dimensioning referred to the main axis.

Terrain model: subproject containing the digital terrain model from which to calculate the profile terrain elevations.

Terrain offset: this value represents an offset distance from polyline on which to calculate terrain elevations. In other words, terrain elevations can be calculated either on the polyline by setting 0 as

offset value, or by considering a supplementary distance from the current position of the polyline.

Open profile graphic window: by activating this option the tool, once calculation has been performed,

opens the graphic window of the profile calculated.

Cut Polylines

It is possible to define some planimetry polylines representing the sections cut lines. On inserting the typical sections and on generating the project planimetry the tool can consider the cut lines and at the same time cut the exceeding part. This function is very useful in designing interchanges ramps, since it

allows to define in the planimetry the cut line that determines the automatic elimination of overlapping areas between the main axis and the ramp.


In order to activate the use of cut polylines it is necessary to gain access to the parametric design in one of the following ways:

Toolbar: Design

Menu Axis > Parametric design

Menu Sections > Parametric design

Menu Profile > Parametric design

indicate the code used for the cut polyline and use it by Apply button.

All the cut polylines must have the same code; a cut polyline can be used to cut sections belonging to other axes.

Staking

Staking commands allow to determine the position of topographic points according to alignment axis, altimetric design and transversal sections.

Different procedures offer solution to the different problems that may arise once the real building phase has started.

The object defined as topographic point has three characteristics that link it to an axis; these properties

are the following:

axis the point is referred to

station from reference axis

offset from reference axis

In this way it is possible to determine survey points not only through X,Y coordinates, but also by

indicating the station and the distance from a reference axis.

The procedures available are the following:

Extraction of coordinates: automatic procedure which, by different options, allows to extract a survey by using alignment axis, altimetric design and cross sections.

Inserting a topographic point by specifying its station and distance from a reference axis.

Calculating station and offset from axis for a group of points

Information from axis: by this command it is possible to indicate a point on the screen and find out the station and the offset from the reference axis; moreover, the tool returns the elevation of that point on one of the cross section elements. The point indicated can also be inserted as survey point.

Besides this:

Profile ProSt profile module contains all the commands for the insertion, the management and the drawing of longitudinal profiles.

A terrain longitudinal profile can be extracted automatically by interpolating the road axis with the triangle mathematical model. The calculation of profiles regarding horizontal alignments can be performed by using sections or by using any intersection of the alignment with the mathematical model,

thus obtaining the alignment real profile.

Longitudinal profiles can be extracted also from cross sections; the progressive distance is extracted from the station of the section itself, while the elevation can be calculated by two means: the elevation of cross element on center line or a section point elevation is used, that possesses a particular attribute. It is therefore possible to obtain supplementary profiles representing, for example, bottoms of ditches, walls, etc.

The insertion of project grade lines is performed interactively, directly from the graphic CAD window.

Vertical curves are then inserted on grade lines through the definition of radii or tangents. From the grade lines and the curves set it is then possible to calculate the project elevation of the sections. Inside the profile it is possible to define up to 10 groups of grade lines and curves; for example, besides the grade lines defining the road project elevation, it is possible to insert grade lines defining excavation depths for hydraulic works.

With the policy check it is possible to verify the congruence of the project parameters of the vertical elements with the policy selected. The tool provides a detailed report verifying, for each element (grade

lines, vertical curves), the congruence of the parameters (slopes, minimum radii) with the current policy and suggests the minimum and maximum values to be adopted.

Besides the usual longitudinal profile (terrain and project), the tool allows the management of supplementary profiles used to report in the drawing other vertical lines, such as road edges, wall elevations, ditch bottom elevations, piezometric elevation, etc. In the profile drawing supplementary

profiles can then appear dimensioned in the same way as terrain and project profiles.

Besides supplementary profiles, it is possible to insert and calculate profile polylines. Also profile polylines can appear in the profile final drawing and then be dimensioned with the chosen mode. Profile polylines can be the result of different elaborations such as the intersection of the alignment with the mathematical model, or the projection of other axes or alignment polylines on the current profile.

There is a specific management for the planning of hydraulic profiles of acqueducts and sewer systems. For any section it is possible to set the sump pit entry and exit elevation as well as the pipeline diameter. The tool will draw automatically sump pits and pipelines.

The management of supplementary data has also been arranged so to allow to personalize the drawing dimensioning by integrating it with all those data which are not managed directly by the tool (street names, pipeline type, type of materials, nature of soil etc.).

Every part of a profile drawing can be personalized. Terrain and project profiles as well as supplementary

profiles can be quoted as stations, partials, elevations, differences in height, etc. The dimensioning can be automatically integrated with the drawing of elevation differences, hectometric, horizontal alignment, position of edges due to superelevations and widenings on curve. For grade lines a specific row has been

arranged while for vertical curves the insertion of a table has been arranged, that reports the project data. It is possible to choose the size of the profile rows and of the text and to put them both under and above the profile drawing. If supplementary data have been inserted, the profile drawing can be completed with these information. The profile drawing can be printed on sheets of any size; the tool can perform automatically optimizations and calculation of new datum level whenever the sheet height is not sufficient to contain the whole drawing.

Additional entities

ProSt Profile module introduces into the CAD some new entities :

Grade lines : segments representing the altimetric alignment of the road ; besides having two

vertexes they can also have two tangent points with other elements.

General tab

In this page it is possible to modify some parameters concerning the drawing of the profile:

Scale. Setting a scale for elevations and distances;

Profile type. Specifying if it is a road or a hydraulic profile;

Miscellaneous. Allows to set a reference elevation for the drawing of the profile and the initial progressive of the road alignment. Therefore, in order to calculate the planimetric position of a point, the

procedure subtracts this value to the progressive of the point so to obtain the progressive referred to the beginning of the alignment.

Grade lines and vertical curves: sets a group of grade lines and vertical curves currently active.

Reference axis: In generating the longitudinal profile final drawing it is possible to add some dimensioning referred to a different axis in the project. This option is particularly useful in case of parallel or pseudo-parallel alignments, since it makes possible to verify, at each station, the alignment elements contained in the secondary axis. Select from the list the axis whose horizontal alignment must be reported in the current profile drawing.

In Terrain model group it is possible to select the reference survey subproject for calculating profile and terrain sections. Reference terrain must be set for each axis, so as to calculate correctly terrain profile, terrain sections and project section sideslopes. If, on carrying out the updating process, the tool finds out that the reference terrain has not been set the following message will be displayed:

By pressing Yes the tool will open the window of dynamic design to allow the selection of the reference survey subproject for terrain calculation.

In Generation from axis group it is possible to select and customize axis data as well as to activate

dynamic updating.

By Dynamic generation from axis option it is possible to update all the axis data each time the alignment and/or its elements are modified. If this option is active the tool automatically notices the changes, determines the data to be updated and carries out the updating.

Axis data table reports the data the tool can update automatically, subdivided according to the module

they belong to (planimetry, profile and sections).

ProSt

279

By Generate column check box it is possible to activate the automatic updating of the corresponding datum, while by pressing on Configure... it is possible to customize the updating parameters.

The axis data the tool updates automatically are the following:

Planimetry Automatic cross-sections: If this option is active the tool repositions automatically the sections situated along the axis and inserts the automatic sections according to the rules set. The tool repositions the sections automatically, according to their typology:

Cross-section by point: Sections by point are repositioned according to the reference

point indicated in the planimetry during the insertion or conversion phase. For example, if the point of reference of a section by point is surveyed point 101, the tool will always position it on the

projection of point 101 on axis.

Cross-sections by station: Cross sections by station are repositioned according to the

value of their station. For example, if the reference station of a cross section by station is 110, the tool will always position it on station 110.

Automatic cross-sections: If possible, automatic sections are repositioned according to

the rules defined; otherwise, they are deleted and inserted again.

Free cross-sections: Free cross sections are not repositioned.

By Configure… text it is possible to customize automatic section insertion parameters.

Superelevation and widenings: If this option is active the tool calculates superelevation and widening

following the reference policy and uses them for the axis.

Warning: In case customized superelevation and/or widening are used, it is necessary to deactivate this option. Otherwise, at the following axis updating the data inserted might be lost.


Geometric section properties: If this option is active, the tool updates the geometric features defined

for the axis, modifying the values of start and end stations, so as to adapt them to the new alignment.



Longitudinal profile Terrain profile: If this option is active the tool calculates the terrain profile along the axis. By Configure... text it is possible to customize the terrain profile calculation parameters.

Grade line and vertical curves: If this option is active the tool updates the project longitudinal profile (grade lines and curves), in order to adapt it to the new alignment, while keeping constant grade line

slopes and curve radiuses. Moreover, if the grade lines are linked to the intersection references in the

profile, the tool repositions the grade lines so as to adapt them to the new reference position.

Additional profiles: If this option is active the tool updates the station vertexes of the supplementary profiles so as to adapt them to the new alignment.

Profile polylines: If this option is active the tool updates the station vertexes of the profile polylines so as to adapt them to the new alignment.

ProSt

280

Profile supplementary data: If this option is active the tool updates the stations of supplementary data so as to adapt them to the new alignment.

Cross-sections Terrain sections: If this option is active the tool calculates the terrain of the sections situated along the axis. By Configure... text it is possible to customize terrain calculation parameters.

Design section: If this option is active the tool inserts project typical sections in axis sections according to the intervals set by parametric design. If the elements of the typical sections inserted automatically are modified manually inside a section window, the tool converts the section into a free section so as to avoid the loss of the changes made, since the elements inserted automatically can be deleted and

modified at any time by automatic insertion procedure.

By the command Update polylines it is possible to update automatically all profile polylines.

Terrain and project profile

The longitudinal profile can be managed by particular tables reporting the distance and the elevation of every station profiles as main data. Anyway, it is also possible to manage direclty from the graphic CAD the profile and the supplementary profiles. As usual, every modification made from graphic CAD will be

automatically made on the table and vice versa.

Insertion of terrain and project stations from graphic CAD

The insertion of a terrain and/or project station from the graphic CAD is performed as follows

Toolbar Profile

Menu Profile > Terrain and Project > Insert terrain section

Menu Profile > Terrain and Project > Insert project section

Command line: PSEC


Section insertion Terrain/Project/2nd profile/3rd profile/4th profile/5th profile/<T>: T Answer T to insert a terrain section and P for a project section.

Enter section position: Indicate by the cursor the position of the section. Terrain elevation: Indicate terrain elevation. Project elevation: Indicate project elevation.

After inserting the first station, the tool resumes the command from the beginning, so that it is possible to continue the insertion. In order to interrupt the requests press ESC key, or ENTER key or the right

button of the mouse.

How to erase and modify profile stations from the graphic CAD

Modify If you want to modify distance and elevation of a station directly from the graphic CAD, you can use all the edit functions offered by the graphic CAD (move, copy, rotate, etc.).

A rapid means to modify distance and elevation of a station is to use Grips (see Grips). Each station has two grips: one near the reference elevation and the other near the station elevation. You have to use the first in case it is necessary to change the distance, the second when you have to change the elevation.

In case of terrain and project stations there are three grips: one near the reference elevation, one near the terrain elevation and the last near the project elevation.

Erase In order to erase one or more stations from the graphic CAD it is sufficient to use the erasing command used to erase any kind of entity.

Table of longitudinal profile

This table contains profile data of terrain and of project. There is a link between the content of this table and the cross sections: in fact, any profile station is a cross section. As far as topographic sections on a mathematical model, this table can be used only to insert the distances between the sections in order to calculate the volumes.

The table can be activated from all of the tool graphic modules: Planimetry, Profile and Sections.

Altimetric elements

The altimetric design of a road is performed by inserting grade lines and vertical curves. From them the tool can extract automatically the stations project elevations.

It is possible to modify the altimetric design by moving with the cursor the alignment vertexes or

stretching the circular curves. In shifting the vertexes it is possible to set a free shifting, or a shifting along one of the two directions set by the gradients or move the vertex only in elevation or only in station. To design hydraulic profiles a working mode is available, which allows to insert the gradients with

difference in height.

You can insert and modify grade lines and vertical curves directly from the graphic window or from a specific window which allows to manage all data in an analytical way.

Insertion of grade lines

The insertion of a grade line can be carried out as follows:

1. Insertion by two points;

2. Insertion by specifying start point, slope and length;

3. Insertion by specifying end point, slope and length;

4. Creation of grade line through a point and tangent to previous/next curve;

5. Creation of fixed slope grade line, tangent to previous/next curve;

6. Creation of grade line tangent to two curves.

Inserting grade lines with difference in height

The procedure for inserting grade lines with difference in height is exactly the same as that for inserting

grade lines without difference in height; the only difference is that, on inserting the grade line, it is possible to insert a difference in height, so the tool calculates the new position of the grade line.

Therefore, the command is available only if the command for inserting a grade line is active.

Interactive modification of grade lines and vertical curves

By this work mode it is possible to modify grade lines and vertical curves by moving with the cursor the curve vertexes or by stretching the horizontal curves.

In moving the vertexes it is possible to set the following types of shifting:

free;

along the direction set by the first or the second grade line.

keep a fixed elevation and change only the vertex station.

keep a fixed station and change only the vertex elevation.

A specific option allows to break the grade line into two parts so as to insert a new curve.

Vertex shifting The command can be activated in one of the following ways:

Toolbar Edit vertex

Menu Profile > Vertical alignment edit > Edit vertex


Note. It is possible to activate the command directly, by clicking on the vertex or on the curve to

modify; the element indicated will be selected and grips will appear on the main points of the element. Now it is sufficient to drag the grip on the vertex or the grip in the middle of the curve.


Indicate vertex to modify: click on one of the two grade lines that determine the vertex to move. Once the vertex has been indicated, it is possible to move the mouse and drag the vertex to the new position. Meanwhile, on the command line, the following prompt will appear:

Vertex position|Free/1st grade line direction/2nd grade line direction/fixed Elevation/fixed Station/Divide: to move the vertex keeping it along the direction set by the first or the second grade line choose option 1 or 2. To move the vertex keeping it on the previous elevation choose E; to divide grade line choose D; to move the vertex keeping it on the previous station choose S. To move the vertex freely choose F.

How to erase and modify altimetric elements

How to modify elements An advanced CAD, like the one offered by the tool, allows to modify all the altimetric elements.

Remember that it is up to the user to choose among the possible changes, since the changes made might determine incoherent situations from the normative point of view.

To modify profile elements activate the following command from Profile module:

In modifying the project profile the tool proposes and displays the minimum values provided for by the policy as far as the radiuses of parabolic and horizontal curves.

Note: if the value introduced is below the minimum value set, and therefore is not accepted by the

policy check, on the corresponding cell the symbol will appear, otherwise symbol will be displayed.

How to erase elements Of course, the elements inserted into an axis can be erased by using the command used to erase any kind of entity. Anyway, the elements must be erased according to a certain order, since the tool does not allow, for example, to erase a grade line if it is connected to a curve; it is therefore necessary to erase

first the curves, then the grade lines.

List of the entities managed by the tool In the left part of the dialog box, there is a list of all the entities that can be used to perform altimetric design.

List of project elements In the upper part on the right all the elements forming the altimetric design are listed. Each line reports the type (grade line, vertical curve and vertical parabola) and the main properties of the element.

Elements properties In the lower part on the right all data are reported of the element selected in the previous table.

How to insert a new element In order to insert a new element, it is necessary to select, from the list on the left, the type of element to

be inserted and then, drag the element into the upper part on the right and drop it in an appropriate position. On the basis of the element selected, the tool checks whether the position chosen is compatible or not with the element; if not, the input process is interrupted. If the tool accepts the insert position a dialog box appears requiring all data needed to create the element.

How to modify an element To modify an element, it is sufficient to click twice on the element itself. The appearing dialog box allows to modify the main data of the element selected.

Check on policy of altimetric elements

Through check on policy the tool verifies the congruence of the project parameters of altimetric elements

with the policy set. The tool provides a very detailed report in which it verifies the congruence of the parameters (slopes, minimum radii) of each element (grade lines, vertical curves) with the policy; in this report the minimum and maximum values to be applied are suggested.

It is possible to select the policy to adopt from Axis menu choosing Axis properties.

Menu Profile > Policy check

Command line: CHKPOLICY

A dialog box similar to the following appears:

Inside the dialog box you will see all the messages representing the result of the check carried out on the axis altimetric elements. The list starts showing some information messages and the calculation of the standard parameters used during the checks.

Going down on the dialog box, you can see the results of the verification performed on each element. The verifications performed on the different elements are the following:

Grade lines: maximum slopes;

Vertical curves: minimum radii;

All messages are displayed together with an icon that allows to understand immediately the type of message. The different types of messages displayed are the following:

Information: message informing about data calculated by the tool.

Speed used for the checking: indicates the project speed in mph set for that segment.

ProSt

Error: this message indicates that the project parameters of the element are not congruent

with the policy set.

OK: this message indicates that the project parameters of the element are congruent with the

policy set.

Pressing button Print it is possible to obtain the complete report of all messages present inside the dialog

box.

Groups of grade lines and vertical curves

Ten groups have been created, which can contain, inside one profile, different vertical designs (grade lines and vertical curves). It is therefore possible to design, inside one profile, not only road elevations but also ditch elevations, wall elevations, network excavation elevations, etc. In interpolating the

elevations it is possible to set the group to use.

As in subprojects, there is an "active" group, which identifies the group where the work is being performed, that is the one where the new elements (grade lines and vertical curves) will be inserted. The grade lines and curves of a single group can be made visible/invisible simply by making the group visible/invisible.

Setting the active group

As in subprojects, also for groups of grade lines and vertical curves there is an "active" group, which

identifies the group where the work is being performed, that is the one where the new elements (grade lines and vertical curves) will be inserted.

The active group can be set in two ways:

Supplementary profiles

Supplementary profiles are lines of profile used to indicate for example ditch or wall profiles, the piezometric of hydraulic profiles or the profile of edges in the planning of a road.

Supplementary profiles can be inserted manually from the specific table or directly from the graphic CAD. Besides, there are some functions which allow to calculate or extract supplementary profiles from

sections, from mathematical model etc.

ProSt

How to erase and modify profile stations from the graphic CAD

Modify If you want to modify distance and elevation of a station directly from the graphic CAD, you can use all the edit functions offered by the graphic CAD (move, copy, rotate, etc.).

A rapid means to modify distance and elevation of a station is to use Grips (see Grips). Each station has two grips: one near the reference elevation and the other near the station elevation. You have to use the first in case it is necessary to change the distance, the second when you have to change the elevation.

In case of terrain and project stations there are three grips: one near the reference elevation, one near the terrain elevation and the last near the project elevation.

Erase In order to erase one or more stations from the graphic CAD it is sufficient to use the erasing command used to erase any kind of entity.

Profile polylines

Profile polylines are a special kind of polylines characterized by an univocal code assigned to them during the generation phase. Profile polylines can be created in different ways:

manual insertion

extraction of polylines from axis projection (X Module)

extraction of polylines from profiles

extracted from axis-model intersection

As for stations, polylines appear in the drawing dimensioning: it is sufficient to indicate the polyline code in the Profile dimensioning.

Manual insertion of profile polylines

Profile polylines can be inserted as normal polylines but with the difference that the tool requires to indicate the code associated to the polyline. The command can be activated through one of the following methods:

Menu Profile > Profile polylines > Insert polyline

Command line: PRPLINE

315

Profile supplementary data

The management of supplementary data has also been arranged so to allow to personalize the drawing dimensioning by integrating it with all those data which are not managed directly by the tool (street

names, pipeline type, type of materials, nature of land etc.).

The table of profile drawing codes is activated through one of the modes below:

Menu Profile > Supplementary data

Command line: SUPPDATA


The dialog box is made up of two tables: the first manages the index of the different supplementary data, while the second manages, for every data of the first, stations and labels to be reported in the drawing dimensioning.

Code. Alphanumeric text allowing to associate the datum content to the profile dimensioning row. In

order to insert supplementary data in the profile dimensioning, it is necessary to indicate the code with

which it has been inserted.

Description. Description of the supplementary datum.

Station. Reference station for text positioning.

Description. Text to be reported inside rows.

Calculation of profile elevations

The tool can calculate profile elevations and extract profiles. Calculation of elevations means that for every profile station only the elevation is calculated, while the station is the same; for the calculation it is therefore necessary that profile stations are already present.

The extraction of profiles allows on the contrary to create new profiles according to different modes; in

case an extraction is performed both the station and the elevation are calculated.

By ProSt it is possible to obtain automatically what is called a real profile, that is to say the intersection between the axis and the terrain mathematical model. This profile represents the real development of the terrain along the alignment, and on sections it coincides with the traditional profile, while it can be

different elsewhere. The real profile makes it possible to check the correct location of stakes on all the main points of the alignment. If the real profile changes remarkably between a stake and the following one, then it is better to add new stakes in that area, to improve the quality of the final result, mostly as

far as the accuracy of volume calculation.

Calculation of profile elevations

It is possible to calculate elevations not only of terrain and/or project profiles but also the elevations of

supplementary profiles.

Calculation procedure is activated through one of the following methods:

Menu Profile > Calculation of profile elevations

Command line: DTM2PRO


Profile calculations of: Selecting the kind of profile to be calculated;

...From...: . Selecting the mode to be used for the calculation of elevations:

Triangles digital model: every station elevation is determined on the surface of a triangle

mathematical model.

DEM: every station elevation is determined by using data present inside DEM (Digital Elevation Model).

Cross-sections: this option is active only for the calculation of terrain and project elevation; every station elevation is obtained from the elevation on center line of the terrain or project line present in the cross sections.

Topographic points: every station elevation is obtained by verifying if the planimetric position of

every point coincides, within the tolerance set, with the survey point indicated; if the tool verifies that a profile station coincides with a survey point, it gives the station itself the point elevation;

Grade lines and vertical curves: the elevation is calculated by interpolating the stake station on

the grade lines and the curves in the group of grade lines and curves selected.

Profile polyline: the elevation is calculated by interpolating the station progressive on a profile polyline to be found in the work with the code indicated. See Profile polylines.

Select sections: indicate from which section to which section the calculation has to be performed; use

buttons on the right of the edit box to consult the list of sections.

Note. Some options are active only when the option has been selected, that specifies the source the data will be calculated from.

ProSt

318

From mathematical model

The profile desired is obtained by the intersection between the axis and the data of the mathematical model. Then, it will be necessary to indicate the mathematical model to use to generate the profile. The profile generated in this way represents the real profile, since it reports all the intersections between the road axis and the mathematical model.

In case the profile is extracted from a triangle model, it is possible to obtain the profile on axis by setting value 0 in input field Distance from axis; on the contrary, by setting a different value it is possible to

obtain the profile at a certain distance from axis. If this distance is not constant, it is possible to create a planimetry polyline and have its terrain profile projected on reference axis; in this case it is necessary to set the option Planimetry polyline and the code of the polyline to be processed.

From survey polyline

The profile is obtained by the projection of a survey polyline on the reference axis. It is possible to specify the code of the survey polyline and the maximum width of the band within which to accept the projection; the polyline vertexes situated at a distance from reference axis exceeding band width will not be projected.

From planimetry polyline

The profile is obtained by the projection of a planimetry polyline on the reference axis. It is possible to specify the code of the planimetry polyline and the maximum width of the band within which to accept the projection; the polyline vertexes situated at a distance from reference axis exceeding band width will not be projected.

ProSt

319

From band

The profile desired is generated by using the survey points situated inside a certain band from the axis set. The width of the band is set by using Band width field.

The option Move points on axis allows to perform the shift of the planimetric position of topographic points on reference axis.

From differential leveling Profile elevations are determined by using data coming from differential leveling.

Cross sections: the profile is calculated taking the sections station and the elevation on axis of an

element found in the cross sections.

Section Flag: the profile is calculated taking the sections station and the elevation of a point found in the section with a flag value like the one indicated in input field. The point can be searched in the whole section or only in the part on the left or on the right of the axis. See Sections flag.

Warning. The command for generating the Planimetry of project allows to generate automatically from section flags also planimetry and profile polylines.

Elevation to add to elevation calculated: it is possible to add to the elevation calculated a delta, either positive or negative.

Pressing Calculate button the tool calculates the elevations according to the settings.

Calculation of real profile

Real profile is the actual development of terrain along the whole alignment; it coincides with the traditional profile on sections, while it can be different elsewhere. The real profile makes it possible to check the correct location of stakes on all the main points of the alignment. If the real profile changes remarkably between a stake and the following one, then it is better to add new stakes in that area, to improve the quality of the final result, mostly as far as the accuracy of volume calculation.

Real profile drawing As far as the generation of the profile final drawing, usually a drawing is required, representing the real profile but reporting the elevations only on section stakes.

In fact, the drawing of a terrain stake is formed by a vertical line, from reference elevation to terrain elevation, on stake station and by two lines linking the stake with the terrain elevations of the preceding and following stake. These two lines must not be displayed when the real profile too is available.

It is possible not to obtain the drawing of these two lines by modifying the settings of Profile codes.

Cross-sections and volume calculations

Cross-sections

The sections management includes not only the automatic extraction of sections from the mathematical model but also the possibility to complete the sections with the insertion of typical elements, working lines etc.

Each work starts with the definition of work parameters; first of all it is necessary to define the elements which will make up the sections: terrain, project, stripping, terrain recovery, etc. Then, some rules have to be defined for area and width calculation, units and other parameters used during the calculation. It is

possible to calculate both cut, fill, terrain recovery, etc. volumes and such surfaces as geotextile, seal coat, binder etc, both in projection and in length.

The program can extract automatically the transversal view of the section from triangle mathematical model, line mathematical model, contour lines and survey points.

Section elements can also be imported from DXF files.

As far as road or hydraulic sections, it is possible to choose from the library the typical section to use or define your own typical section; then you go on with the insertion of the typical section in the current section or automatically in a group of sections.

The tool also allows the calculation of areas for each section and to verify directly on screen the calculation performed; finally, by setting the distances between sections, you can obtain the calculation of volumes.

Sections can be plotted together with the dimensioning of their elements, personalizable by the user. Along with the drawing it is possible to print the reports concerning area and volume calculations.

Section module introduces just one new entity: the polyline representing the elements by which the sections will be built: terrain polyline, project polyline, stripping polyline, etc. Each polyline possesses a code that distinguishes it, allowing to perform the calculation of section areas properly.

Sections module Menus

Cross section personalized menus are :

Sections : including menu items to manage calculation of sections, elements editing, definition of dimensioning, calculation of areas, etc.

Section editing : including menu items for the insertion of new elements inside the cross sections.

Moreover, the following items are added in File menu:

Project properties : including the setting of all the parameters for the management of the project. It is very important to know these parameters that can be modified by this menu item.

Plot preview : this item is active only for profile and sections module and allows to open a graphic window containing the profile and sections drawing preview. From the new graphic window it is then possible to go on as usual by plotting and creating DXF file.

Cross sections module adds the following toolbars.

Toolbar Design: contains some of the commands concerning the product management.

Cross-sections Toolbar: it includes some of the commands concerning the management of cross sections.

Section editing Toolbar : it includes some of the commands concerning the insertion of new elements

For the users possessing the X module, the Road intersections toolbar will be displayed:

How to move quickly among sections

For certain works the number of cross sections can be very high. For this reason it is necessary to move rapidly from a section to another. In order to meet this need, a navigator has been created. It is situated in the lower part of the sections graphic window.

Navigator is made up of five buttons whose meaning is specified below :

Load first section

Load section preceding current section

Load section following current section

Load last section

Section currently displayed in the graphic window;

Search a section

Allows to update the current section without having to reactivate the dynamic design and the updating of the whole axis data. The command re-calculates the terrain line and inserts the typical

section only on the current section;

allows to navigate to the right correlated section.

Cross-sections properties

Many data and parameters concerning not the open subproject but the active subproject are grouped in

this section. This means that inside any project there can be more subprojects, each one with its own general data, apart from the others (see Management of subprojects).

It is possible to gain access to the Cross-sections properties by the following modes:

Menu Sections > Cross-sections properties

Command line: DDSECPROP


ProSt

342

General tab

Terrain code Shows the code used for the terrain line in cross-sections. This is useful in performing

those elaborations where a terrain line is used (e.g. slope calculation), because the tool avoids making one more question. In Section codes table an element, used as terrain line, must be inserted with the same code inserted here.

Project code Shows the code used for the project line in cross-sections. The rules are the same as those

for Terrain code, so it is necessary to insert in Section codes table an element with the same code as the one inserted here.

X, Y scale Allows to set drawing scales for abscisses and ordinates. It is possible to use also SCALEDRAW command on graphic CAD window.

Decimals It is possible to choose the number of decimals with which to represent coordinates, widths, areas, surfaces and volumes.

Section view If the option Store section view is active the tool saves, for each section, the last view you used; by this means, when you go back on the section, the last view you used in that section will be

shown.

OK button confirms the changes made, while button Cancel exits the dialog box without making any change. By button

Apply it is possible to confirm the changes and see in the CAD window the result of these changes while keeping the dialog box active.

Calculation tab

Automatic Allows to activate/deactivate automatic recalculation of sections when you go out of a section.

by Gauss method Applies Gauss method to determine the section areas. It is also possible to use a method that consists in breaking each area into triangles and trapezia.

Volume calculation with barycentre: Volume calculation on sections can be performed by considering

the position of the figure barycentre compared to the axis. In this way, quantities on curve are considered more precisely. After the setting, it is necessary to perform volume and area calculation. If volume calculation has been performed with barycentre, then the report will consider also the radius values of the curve passing by the figure barycentre and the corresponding multiplicative factor allowing the correction of the volume calculated.

Calculation of triangle widths For width calculation in case of figures with triangular extremes, the tool can calculate the total width, as well as the width on the median point of the triangular face and on the

inner extreme.

Areas to calculate Allows to decide whether to calculate the whole section or only its right/left side (as to the axis).

ProSt

344

S.O.P. tab

It is possible to carry out volume calculation even only on one part of the section; by this way, it is possible to obtain volumes up to a specified elevation or between two elevations. It is also possible to

specify two elements inside the sections to be used as a limit for the calculation: you can then calculate volumes up to a specified section element or between two section elements.

In this page it is possible to specify whether you want to carry out elaborations by State of Progress; in the affirmative case, it is possible to specify the name of the S.O.P. and the two elements to be used as limit in volume calculation.

The start element and the end element names must coincide to those of the elements present in Section codes, Lines tab table.

If inside the sections there are elements having the same code as the one set in the previous fields, areas calculation will include only the areas present between the two elements.

If the option Elaboration with S.O.P. has been activated and the options have some S.O.P. elevations, the graphic window will report a horizontal line at the different elevations.

Elaboration codes

The module for cross-section management allows the management of every kind of section: road, railway, hydraulic, etc. In order to make the tool as versatile as possible, the operator can define:

d. the elements that make up a section (terrain line, project line, stripping line, terrain recovery line, etc);

e. the quantities to be calculated (cut, fill, stripping, terrain recovery);

f. the calculation procedures of the preceding quantities, which can be computed both as areas (cut and fill) and as widths (Seal coat, geotextile, topsoil). This option is available only in tools

equipped with Accounting Sections module, by which it is possible to set one's own calculation

rules in order to determine any quantity from the cross-sections. If the tool is not equipped with Accounting Sections module, calculation rules are fixed and allow to count the following quantities: cut and fill, backfilling, gutters, ditches and walls, pavement, stripping.

g. hatches have to be automatically assigned to calculated areas: it is possible to fill automatically some of the calculated areas by using a hatch model so as to create a drawing understandable even to those who are not allowed to works.

The management of the elaboration codes is therefore subdivided into the following phases :

Definition of the codes of the elements to be inserted in the sections

Definition of areas to calculate in the sections

Definition of area calculation sequence in the sections (only in the configuration with Accounting sections

module)

Setting area hatches (optional)

An example is set from which you can learn how to personalize section calculation.

Definition of the codes of the elements to be inserted in the sections

The definition of section codes is activated as follows:

Menu Sections > Section codes

Command line: ELABCOD

In the appearing dialog box select Lines page for the management of the elements to be inserted.

ProSt

347

This table allows to define the codes of the elements (lines) with which the sections will be built. By section elements we mean for example terrain line, project line, terrain recovery line, etc. It is not possible to insert in the sections lines that have not been inserted in this table before. This is therefore a very important table so that the sections work properly and it must absolutely be edited.

If the work has been created on the basis of a model file, you will find the table already set, even if modifiable.

The data required for each line are :

Code: It is a code or an abbreviation used during the phase of section input in order to identify the element to be inserted or modified (there must not be equal codes!). In the table it is necessary to input codes for terrain and project lines, as defined in Cross-sections properties.

Description: It is a text used to describe the kind of line. This description is reproduced in the reports of

the elements and in some tables for the selection of the elements to be elaborated. The text must

describe the element it represents and it must never be left empty.

V.Seg: It is an indication for the drawing of the sections dimensioning and is used to trace the vertical segments connecting the points of the elements as far as the reference elevation. There are three possibilities:

No. No segments traced.

Complete. A complete segment is traced, connecting the points of the element to the reference elevation. Partial. The complete segment is traced only for the first and the last point.

Pavement layers: the area belongs to the pavement layer.

Layer. It is possible to set a layer for any element; this solution allows therefore to manage the aspect

(colour and linetype) of the entities drawn.

Type. The value set in this column is used by the procedure for the guided creation of area calculation sequence. It is possible to select one of the following values:

None: the line has no particular meaning and will not be used for the guided creation of calculation sequence.

Cut: the line represents a cut element if compared to terrain line.

ProSt

348

Fill: the line represents a fill element if compared to the lowest cut line.

Pavement layers: the line belongs to the pavement layer.

Terrain: the line is the existing terrain line; only a line from the list can have this attribute.

Project: the line is the one representing the project for cut and fill calculation; only a line from the list can have this attribute.

Join: this option is used on inserting the typical sections in the cross sections. If the option is active, the segments with the same code and with the extremes in common will be joined to form lines.

KZREB: not used.

Planimetry of project tab By selecting Planimetry of project tab, in the lower part of the table, the following window appears:

In this table it is possible to specify, for each element, the different properties determining the way planimetry of project is generated and the tridimensional model of the road:

Plan: this property can assume the following values:

None: the element is not considered for the generation of the planimetry of project.

Top line: the element is considered for the generation of the planimetry of project, but the tool will use only the element segments which are not "covered" by any other segment; only the visible part of the element will be used. It is convenient to activate this property only in

case of elements at the top of the section and not for those which are under other elements.

Complete: the element is considered for the generation of the planimetry of project in a complete way, so any of its segments will be reported in the planimetry of project. It is convenient to activate this property only in case of elements to be exported integrally into

the planimetry of project, such as guard-rails, fences, etc.

ProSt

349

DTM break: this option must be activated for those elements along the outer part of which the terrain model must be broken. For example, in case of sections having the project line represented by the sideslope of the road and a line representing a ditch, it is necessary to select the project line code and the ditch line code; in this situation, the tool will use the ditch boundary as terrain model cut polyline and will delete automatically all triangles of the terrain inside the ditch; then the tool

will perform the same operation for the project boundary.

Slope hatches: activate this option if you want to display the slope hatches drawing of the corresponding element.

Hatch: in this column it is possible specify whether in project planimetry the element must be filled with a color or with a hatch choosen among those loaded in the project. See How to load hatch patterns.

Angle: start angle for hatch drawing.

Scale: scale factor to be applied to the hatch model.

Colour: colour by which to display the hatching or full colour to use. If Slope hatches option has been activated and the slope of the segment to represent is negative, then this colour is used; otherwise, the colour set in 2nd colour property will be used.

2nd colour: colour by which to display the hatching or full colour to use. If Slope hatches option has been activated and the slope of the segment to represent is positive, then this colour is used;

otherwise, the colour set in Colour property will be used.

Note. By setting two different colours in Colour and Colour 2 properties for the element that defines the slope in the cross sections it is possible to have a different coloration for cut sections and fill sections respectively.

Definition of areas to calculate in the sections

The definition of section codes is activated as follows:



In the dialog box now appearing, select Areas for the management of the areas to calculate.

If the work has been created on the basis of a model file, you will find the table already set, even if modifiable.

The table included in this page allows to define the codes of the quantities (areas) the tool has to extract

from the cross sections; the quantities to be calculated can be for example: cut and fill area, pavement area, subgrade area, etc. The quantity to be calculated can be an area or a width (the latter both in projection and in length). The tool will calculate only the quantities of the items defined in this table, which must therefore be compiled.

The data required for each line are:

Code It is a code or abbreviation used during the section calculation phase in order to identify the

features of the value calculated (area or width). There must not be double codes. In case the code is not identified, the description itself becomes the title for all the quantities defined in the following lines (as far as the next empty code). The title is reproduced both in the reports and in the summary tables of the

sections drawings.

Type indicates the kind of value to be calculated:

Area the area is calculated ; Plane width a width is calculated by summing the plane widths; by volume calculation a surface

will be obtained.

ProSt

351

Sloping width a width is calculated by summing up the sloping widths; by volume calculation a surface will be obtained.

Description It is a text used to describe the kind of area/width. This description is reproduced in the drawings, in the reports of the elements and in some tables for the selection of the calculated areas. The text must describe the quantity it represents and it must never be left empty.

Decimals Number of decimals to be used for quantities report.

Equalized code In case of equalized areas specify the code of second area with which the equalization is performed (for example Cut must be equalized to Fill and vice versa). The two areas of equalization must be of the same kind. In order to perform the cut and fill volume calculation by using equalized areas mode, it is necessary to assign to cut area the equalization code of the fill area, while the fill area requires the code of the cut area.

Accounting Represents the code of the item from price list that corresponds to the quantity calculated.

It can be left empty without influencing any elaboration. If available, it is reported in the drawings and used for exporting areas and volumes into the program for estimate and accounting Opera.

Visible By this option you can decide whether to reproduce, in section drawings and reports, the result of the area calculated :

No: no reference to the area inside the section drawing is displayed;

Totals: inside section drawing only the total of the area is displayed;

Formulas: in the section drawing only formulas are displayed; in order to display formulas, it is

necessary that a sufficient margin, in Definition of section dimensioning, had been set for them to be drawn.

Totals and formulas : in section drawing both totals and formulas are displayed ; in order to

display formulas, it is necessary that a sufficient margin, in Definition of section dimensioning, had been set for them to be drawn.

Average with empty: by activating this option, the corresponding volume will be obtained by an average between the areas of the two sections, even if one of the two sections has area 0; vice versa, by deactivating this option, if one of the two areas has value 0, also the volume will be 0.

Type. The value set in this column is used by the procedure for the guided creation of area calculation sequence. It is possible to select one of the following values:

None: the area has no particular meaning and will not be used for the guided creation of

calculation sequence.

Cut: the area must be considered as a cut area if compared with terrain line.

Fill: the area must be considered as a fill area if compared with the lowest cut line.


To each area, it is possible to associate a hatch model or a solid color automatically so that inside the section drawing each area is different from the other.

Definition of area calculation sequence in the sections

Note. This section is active only in ProSt-Standard configuration. Calculation rules are fixed for ProSt-Basic and allow to calculate the following quantities: cut, fill and backfilling, gutter, ditch, pavement layer and wall, stripping line and land recovery excavation, wall excavation, wall cutting and

trench.

The definition of the section areas calculation sequence is activated as follows:



ProSt

352

In the dialog box now appearing select the tab Calculation sequence for the management of the mode by which to calculate areas.

The base principle of the calculation of quantities follows the sequence of cut and fill operation so as they

are made. The calculation of quantities is performed by extracting from the section two elements at a time (inserted as lines) and by calculating the areas between the two lines; therefore, two quantities are obtained, one of cut, the other of fill.

For example, suppose you have a terrain line as begin code and a project line as work code. The tool calculates a cut area in those parts where the project is lower than the terrain and a fill area in those parts where the project is above the terrain line.

Every line in the table corresponds to an elaboration; for each line the following data are required:

Start code. Code of the element to be used as start line for the calculation of areas. You will have to apply to this line the line defined in the following field. If, no value is assigned the line resulting from the elaboration of the previous field will be considered as start line. The possible codes are listed in Lines tab.

Work code. Code of the element to be used as work line for the calculation of areas. This line is applied to the start line. The possible codes are listed in Lines tab.

Work type. In this field it is specified whether the operation performed on the start line is a cut or fill

operation. As a consequence, a new line is generated, and it is called resulting from the fusion between start line and work line. This line will be used in the next elaboration.

Down - Minimum profile the resulting line will be made up of the start line and of those segments of work line where elevations are lower than those of the start line. As a result, you obtain a line that represents the minimum profile of the two lines.

Up - Maximum profile

the resulting line will be made up of the start line and of those segments of work line where elevations are above those of the start line. As a result, you obtain a line that represents the maximum profile of the two lines.

Under. Request for a code defined in Areas tab (Areas to be calculated). To this code the cut area

obtained by calculation will be assigned.

Over. Request for a code defined in Areas tab (Areas to be calculated). To this code the fill area obtained

by calculation will be assigned.

Mem. Allows to memorize the result of the cut and fill operation so that it can be used in a following line both as start line and as work line. The result of the elaboration can be saved in one of the other elaboration lines or it can be saved with a number from 1 to 9; in this case, to retrieve the working in

ProSt

353

column Start code or Elaboration code it is necessary to repeat the number preceded by the character ":".

Draw. If in Mem column the result of the elaboration has been assigned to another elaboration line, this line might be inserted in the sections drawing and then be used, for example, for dimensioning. In this way the tool can generate lines which are not drawn but derive from area calculation.

Calculation of single elements The tool can calculate, for every single section, also areas (wall cutting, pavement layer, topsoil, etc.), lengths (non-woven fabric, compaction, etc.) and widths (wearing course, binder course, etc.). In order to calculate these elements you have to set as Start code the code of the line to be

elaborated. Nothing has to be specified concerning Work code and in the column Work type it is necessary to set one of the following values:

Area. the area will be calculated, of the line whose code is specified in Start code cell. Length. the length will be calculated, of the line whose code is specified in Start code cell. Length No V.Seg. the length will be calculated, with the exclusion of the vertical segments, of the line whose code is specified in Start code cell. Horiz.Length. the horizontal length will be calculated, of the line whose code is specified in

Start code cell. Num.Vertexes. the number of vertexes will be calculated, of the line whose code is specified in Start code cell. Quantity. the number of lines will be calculated, whose code is specified in Start code cell.

In Under cell it is necessary to indicate the code of the area in which the calculation result is memorized. The possible codes are listed in Areas tab (Areas to be calculated).

Clicking on button Preview, it is possible to check directly the correctness of calculation sequence settings without having to close the tab and perform command Totals on screen.

Instead, Create button activates a guided procedure which collects information concerning the different lines to account and the relationships between them. By this procedure, completely guided and interactive, also the unexperienced user who is not keen on the method the tool uses to calculate volumes, can easily obtain the results desired.

Guided creation of calculation sequence

Note. This option is active only in ProSt-Standard configuration. Calculation rules are fixed for ProSt-Basic and allow to calculate the following quantities: cut, fill and backfilling, gutter, ditch,

pavement layer and wall, stripping line and land recovery excavation, wall excavation, wall cutting and trench.

The definition of the section areas calculation sequence is activated as follows:

The calculation sequence by which the tool can then calculate areas, surfaces and quantities can be prepared automatically by a new guided procedure collecting the information about the different lines to account and the relationship between them.

The procedure, completely guided and interactive, enables also the unexperienced user, who is not

familiar with the method the tool uses to calculate volumes, to obtain the desired result.

The procedure is based on the principle by which some lines stand for cut elements, some other lines stand for fill elements and others for the pavement layer. These lines can be associated to the corresponding areas, which, in most cases, have also the same code and are therefore cut areas, fill areas, and pavement areas.

The purpose of the procedure is to enable the user to define these couples of lines-areas in the exact sequence they are carried out with; according to the main sequence, cut elements must be performed

first, then the cut is gradually filled and finally comes the pavement layer.

An example of how to fill Elaboration codes tables

In order to learn how to use the tables, suppose you have to calculate some sections containing the

following elements:

terrain line

project line

pavement line

stripping line

terrain recovery line

backfilling of terrain recovery line

According to the price list, the following quantities will be calculated:

cut and fill area

pavement width (plane width)

stripping width

terrain recovery area

backfilling of terrain recovery area

The table of the elements to be inserted will be defined as follows:

The table of areas to calculate is defined as follows :

ProSt

360

You can see how cut and fill, terrain recovery and backfilling report Area as work type, while pavement and stripping report Plane width.

The table for area calculation sequence is the following:

Now we shall see the meaning of the table lines:

Line 1: TER terrain line is used as start line and PRO project line is used as work line; as work type you have to set Down - minimum profile. The tool intersecates the two lines (terrain and project) and from

this intersection it memorizes the minimum profile represented by the two lines; besides, the cut area, determined by the possible project line under the terrain, is memorized as under area with CUT code. Over area is not assigned.

Line 2: as start line is now used the line resulting from the calculation of line 1 (that is the minimum profile between the two lines); as work line the stripping line is used. Again, the tool takes into

consideration, for the following elaborations, the minimum profile between the two lines intersecated. The under area, determined by the intersection of the two lines, is memorized with STRIP code, and the area width is extracted from it. Over area is not assigned.

Line 3: as start line is used again the line resulting from the previous elaboration (terrain minus project excavation minus stripping excavation) while as work line the terrain recovery line is used. The work type is set again as Down - minimum profile. The under area calculated is computed as terrain recovery area TREC while over area is not assigned.

Now all the cut operations to be performed in the section are finished; fill operations have to start.

Line 4: the line that results from the elaboration of line 3, representing the bottom line of all excavations, is used as start line. As work line the backfilling of terrain recovery line BFILL is used. In this case the work type is set as Up - maximum profile, thus obtaining, from the intersection of the two lines, the line with the biggest profile. The over area calculated is assigned as backfilling of terrain recovery area (BFILL code), while under area is not assigned.

Line 5: as start line the line is used, that was elaborated on the preceding elaboration, that is the line of maximum profile between the excavation bottom line and the backfilling of terrain recovery line. As work line the project line PRO is considered, that was used on line 1 and is now recalled in order to calculate the fill area. As work type again the maximum profile has to be considered. The over area resulting from the intersection between the two lines is assigned to the fill area FILL, while under area is not assigned.

Line 6: this line is used only for the calculation of the pavement, which is situated above the project line. As start line is then assigned project PRO and as work line the pavement PAV. As work type the

Maximum profile is assigned, even if , being this the last line, this value is not important, since the

resulting line will not be used by any other elaboration. Under area is not assigned while over area is assigned to the pavement area PAV, from which the length will then be extracted.

Even if some work lines are not available, the tool performs area calculation in any case, ignoring the lines where they are recalled.

Filling areas calculation table is of the utmost importance, since it is in this table that you determine how areas must be calculated. After setting a calculation table, it is better to test the accuracy of the

ProSt

361

calculation, by carrying out the calculation of section areas (CALCULATE command) and to verify the calculated areas by Totals on screen command from Sections menu. It is not necessary to check all sections but only some of them in order to verify if data are set to produce the results needed.

Setting area hatches

The tool allows to fill each calculated area by using a hatching model among those suggested or by using a solid color.

The definition of area hatches is activated by the following menu:



In the appearing dialog box, select the Areas tab and then, in the lower part of the table, select the item Area hatches.

Code. In the first column of the table the codes of the areas, set in Area tab, are recalled.

Hatch. For each area it is possible to set the hatch model chosen among those loaded in the file. See How to load hatch model.

Angle. It is possible to associate a start angle to the the drawing of the hatch.

Scale. It is possible to assign a scale coefficient to the drawing of the hatch.

Layer. It is possible to assign a layer on which the area hatch will be drawn. The hatch will be of the

color defined by the layer.

Management of cross-sections

Insertion of cross-sections

Cross sections can be inserted through different ways according to the kind of work to be performed. In fact, it is possible to insert topographic sections on a mathematical model, or sections on a road axis, or

finally you may want to draw sections by inserting manually all the elements including also the terrain

line, which is then not calculated by the tool.

The tool manages sections which are considered profile stations, so every time you insert a section it means that you insert a profile station.

ProSt

362

Cross-sections in planimetry

After the road axis is set, you can continue the planning phase by positioning the cross sections on the

alignment. Therefore the stations are set, where the sections are situated and it is then possible to calculate terrain longitudinal profile and terrain cross sections.

The sections can be inserted as follows:

Automatic mode: inserts the sections in the alignment main points (extremes of horizontal straights, tangent points, etc.) and allows to insert sections at a specified interval.

Manual mode: allows to insert manually the sections into the alignment.

Table: from the profile table it is possible to add / modify the station of the sections inserted in the

alignment.

All these methods allow to insert some stations along the axis.

According to the positions chosen in Axis properties by menu item Labels position section the graphic order of the text indicating station and section number can vary as illustrated in the following examples:

Modify sections from planimetry graphic window Sections on axis have now been provided with grips allowing to modify them quickly and easily:

The first image shows the grips of an automatic section, while the second shows the grips of a section by Point, by Station or Free. The external, arrow-shaped grips allow to stretch the section drawing, while

the two internal grips allow to rotate it; the central grip allows to move the section along the axis.

To have the grips displayed it is sufficient to select the sections.

ProSt

363

Terrain and project profile

The longitudinal profile can be managed by particular tables reporting the distance and the elevation of

every station profiles as main data. Anyway, it is also possible to manage direclty from the graphic CAD the profile and the supplementary profiles. As usual, every modification made from graphic CAD will be automatically made on the table and vice versa.

Dynamic sections

By the management of dynamic sections it is possible to open a window which displays dynamically the longitudinal length of sections in the following situations:

insertion

selection

modify by grips



Toolbar View

Menu View > Dynaminc Profiles/Cross-Sections



The upper side of the window reports a toolbar, allowing to set calculation mode and display of the dynamic section.

The first 6 buttons allow to choose the data source to use to calculate the section:

Section is calculated by using line mathematical model (break lines / constraints)

Section is calculated by using triangle mathematical model

Section is calculated by using contour lines

Section is calculated by using survey points

ProSt

364

Section is calculated by using the survey points situated within a certain band.

Section is calculated by using DEM.

The following check list reports the survey subprojects available. It is possible to calculate the section by using more models at the same time.; it is sufficient to activate calculation on model by turning on the corresponding light.


Also in this window it is possible to choose the data source to use; it is also possible to specify some parameters such as the tolerance between section vertex and point or the width of the survey band

within which to consider the points to use to extract the section.

For road sections it is possible to set the width of the terrain band to survey on the right and on the left of the axis.


Dynamic section window will display the section transversal length, on executing the following commands:

Insertion: on inserting a topographic section or section on axis, the section transversal length will appear in the window of dynamic sections.

Selection: by selecting a section from the graphic window, the section transversal length will appear in the window of dynamic sections.

Modify by grips: by selecting a section and stretching its grips, the section transversal length will appear in the window of dynamic sections.

Modify by Move and Rotate: by using Move and Rotate command on a topographic section, the

section transversal length will appear in the window of dynamic sections.

Calculation of section elevations

The calculation of section elevations is carried out by using the mathematical model as source from which

to extract all data needed. Before carrying out the calculation it is however better to make sure that in the Section codes - Lines tab table there is at least one element.

The extraction of the transversal view of cross sections can be performed by using triangle mathematical model, line mathematical model, contour lines or survey points. Combinations among the different types of data are also admitted.

ProSt

365

The calculation phase begins in Sections module by giving DTM2SEC command or by selecting Calculation of section elevations from Sections menu.

Menu Sections > Calculation of section elevations

Command line: DTM2SEC

Sections to be calculated In this part it is possible to decide on which sections the calculation has to be performed; it is possible to calculate All the sections, only the Current one (displayed by the CAD window) or choose the Group of sections to be calculated.

Band to be calculated For road sections, i.e. sections inserted along a horizontal alignment, it is possible to set the amount of terrain to be calculated on the left and on the right of the axis.

Calculation from From Origin check list select the mode to use to extract the sections:

ProSt

366

Digital model

Data used are those present inside the survey digital model:

Triangle digital model: the extraction is performed by intersection between the triangles and the vertical plane determined by the section. From the intersection you obtain the polylines that

form the transversal view of the section;

Break lines: the extraction is performed by the intersection between the break lines and the vertical plane determined by the section. From the intersection you obtain the polylines that form

the transversal view of the section;

Contour lines: the extraction is performed by the intersection between the contour lines and the vertical plane, determined by the section. From the intersection you obtain the polylines that form the transversal view of the section;

DEM The extraction is performed by using data present inside DEM (Digital Elevation Model).

Survey points

The extraction is performed by using directly survey points, without having to build a mathematical model; this is useful especially when the section points are surveyed on site. For each point of the polyline, representing the section planimetrically, the tool verifies whether it coincides, inside the

Tolerance set, with a survey point. If so, that point is used to build the cross section.

ProSt

367

The option Extract description by points reports, in section drawing, the descriptions of the points used to generate the cross section; the description text is reported vertically near the point.

The option Extract symbol by points code allows to report, in the section drawing, a symbol near the points used to generate the section. The symbol to report is linked to the point survey code. Codes button allows to set the following relations:

For each survey code it is possible to set a symbol/block to use to represent the point in the sections. It is necessary to set also the size to assign to the symbol/block.

Survey band

In this case a band is set, both in front and behind the section, inside which it is possible to search for

the survey points; the band width is set in Band width input field. If a point is found inside the band the tool considers the projection of the point on the section and from the projection it calculates the point distance on the section. This kind of extraction is particularly useful in survey by road sections and canal or, in general, in case a group of points are surveyed transversally to the axis; since points are almost never aligned, to perform the calculation it is possible to set a band in order to consider them as they were aligned

Select the option Survey points to use all the points of survey subproject, and select Survey polyline to

generate the section only from survey polyline vertexes.

In case sections are generated from survey points it is possible to use supplementary options:

By the option Move points on cross-section line it is possible to move automatically topographic points from their original planimetric position to the projection on the section planimetric line.

The option Extract description by points reports, in the section drawing, the descriptions of the points used to generate the cross section; the description text is reported vertically near the point.

The option Extract symbol by points code allows to report, in the section drawing, a symbol near the points used to generate the section. The symbol to report is linked to the point survey code. Codes button allows to set the following relations:

ProSt

368

For each survey code it is possible to set a symbol/block to use to represent the point in the sections. It is necessary to set also the size to assign to the symbol/block.

Terrain profile For each section a horizontal line is created. It has an extension on the left which depends on the value set in the Band to be calculated on the left field and an extension on the right that depends on the value set in the Band to be calculated on the right field. The elevation of the line will be extracted

from the terrain elevation set for section calculation. This option is useful when you have no other survey points except for the point on alignment or on hydraulic project and the terrain around the sections is supposed to be on the same elevation of the axis.

Project planimetry In calculating the cross sections the tool can use the project planimetry of the axes contained in the

project. This new mode of section extraction allows for example to obtain sections in which the cross sections of all the axes intersected by the section itself are represented; take for example complex projects with different road axes, tunnels, gutters, railways, etc. In such cases it is possible to create

general sections cutting the whole project and then test on them the relationship, for example in terms of distance, between the axes.

Calculation options Delete previous data: if this option is active the tool will replace the existing data with the new ones

calculated.

Projection on line connecting first and last point of section polyline: With this option active you can decide whether the distance, to be assigned to calculated points, must be the real distance or the distance of the point projection on the line connecting the first and the last point of the section.

Display intersection with other cross-section: when this option is active the tool verifies, for each section, whether it intersects other project sections; in case an intersection is found, in the section drawing a vertical text is reported on the intersection. The text reports the name of the section with

which an intersection has been found.

Press Next button to go to the second part of the calculation. The elaboration can be performed in two methods:

Single: a section line is calculated from a single digital model or from a single DEM (the option Calculation from DEM must be active);

Multiple: section lines are calculated from different digital models or from different DEM (the

option Calculation from DEM must be active)

ProSt

369

Single elaboration

The single elaboration mode is activated by selecting the option Single in the upper part of the window; select the section element to be extracted from the calculation and the subproject to be used as base of data. Press Calculate button to start the calculation.

Element to calculate: indicate the only section element to be created to represent the transversal development of section.

Elements by planimetry layers: In calculating the cross sections from digital triangle model, the tool can verify the layer the triangles belong to and then create distinct elements. If the triangles of the mathematical model have been assigned to different layers because they represent, for example, materials strata etc, the tool can consider this difference and create section elements separated from

each other, as if the triangles belonged to distinct models. By activating this option the tool will not

calculate a specific and single section element, but more section elements according to the layer the triangles belong to. The tool analyses the layer of the triangle processed and verifies whether a section element code exists, which has been assigned to the same layer; if the correspondence is found, a section element will be created with that code, otherwise a new section code will be created.

Start digital model: select the subproject to be used as database.

If the sections are calculated from the project planimetry, the window does not display the whole list of

survey subprojects but the list of the axis subprojects to analyse in the calculation:

ProSt

Press Calculate button to start calculation.

Multiple elaboration

ProSt

371

On the left side of the section the tool reports the section elements that can be used, while on the right side the tool reports all the projects currently opened; for each project, the tool reports all subproject, or DEM, that can be used. Select the section element to calculate and the corresponding subproject to be used as a base of data; then select Add: the elaboration is reported in the lower part of the window.

Perform the same sequence of operations to extract the other section elements.

If the option Elements by planimetry layers is activated, it will be possible only to add the subprojects to process, and it is not possible to associate them a section element, because the element will be obtained according to the layer the triangles belong to.

Pressing button Calculate all elaborations reported in the list are carried out at the same time.

This mode is particularly useful when it is necessary to extract cross sections from different mathematical models: existing terrain, project, first state of progress, etc.

Once the elaboration is finished the lines calculated will appear in the CAD window.

Note. Each time this command is performed, a section element is calculated; with the same data, if this command is performed more than once you can obtain several section elements overlapped that may bring to a volume calculation result higher that the real one. When you have to perform a calculation that will replace the previous one, be sure that the option Delete previous data is active.

Delete and modify transversal elements

How to erase a polyline In order to erase the polyline of a section element directly on the graphic CAD box, it is sufficient to use the erase command used to erase any kind of entity.

How to modify a polyline In order to modify a polyline, directly on the graphic CAD box, you can use, of an element, all the edit functions offered by the CAD.

How to import cross sections from DWG/DXF files The procedure of importation of DWG/DXF files in cross-sections is the same performed in the planimetry graphic window but with a little difference. This difference consists in importing DWG/DXF files containing sections directly on the sections themselves; in this way it is possible to avoid having to perform manually section by section the import command. Then, the purpose is to dispose of a method that allows to carry out the importation of DWG/DXF files in groups, each one to be imported in a specific section already set. It is then necessary that sections, where DWG/DXF files will be imported, have already been created.

Then, it is necessary to create a DWG/DXF file for each section; to make the tool understand which section each DWG/DXF file refers to, it is necessary to follow the rules listed below:

1. the name of all DWG/DXF files begins with the same prefix. (for example: Test).

2. together with the prefix there must be a numeric value corresponding to the number of the section the DWG/DXF file refers to; (Example: Test5.DXF refers to section n.5)

To activate the command follow one of these modes:

Menu File > Import/Export > DXF IN

Command line: DXFIN

The tool asks to indicate the folder where DWG/DXF files to be imported are saved and their common prefix. Finally, you are asked to indicate the group of sections where DWG/DXF files have to be imported:

Now, the tool will import in each section of the group the corresponding file DWG/DXF according to the

rule explained before.

For each polyline imported the tool verifies its layer; if the layer coincides with one of the layers assigned to one of the section elements then the tool transforms the drawing polyline into a section element having that layer. If the polylines are located in different layers it is however possible to go on with the transformation through Entities transformation command.

ProSt

377

The import command together with the export command allows, for example, to export sections on another CAD, modify them and then import them again inside the tool. See How to export cross-sections on DXF files

How to export cross sections to DWG/DXF files Cross-sections can be exported on DWG/DXF files by the following two methods:

1. First carry out the sections plot preview and then perform the command to export DXF file of the sheet or sheets obtained.

2. Perfom directly the command to export DWG/DXF file from one of the graphic windows containing one section.

In the last case, for each section a DWG/DXF file is created and besides, through this method, sections are exported in real coodinates and are not scaled on sheet as happens with the first method.

Sections in real coordinates inside another CAD represent a great advantage; in fact, it is possible to work on them without having to make particular calculations to adapt commands to the scale and moreover it is not necessary to re-scale them

To activate the command follow one of these modes:

Menu File > Import/Export > DXF OUT

Command line: DXFOUT

The tool asks to indicate the folder where to save the DWG/DXF file and the name to assign. Pressing

button Options it is possible to check some parameters that regulate the creation of the DWG/DXF file.

See How to export to DWG/DXF file.

After having indicated the name of the DWG/DXF file to create the tool asks to indicate the group of sections to be exported:

It is necessary to indicate the number of the first and the last section of the group. Pressing on the button on the right you get into a window thast lists all the sections available. To select one section it is

sufficient to click twice on the table row or press OK button.

As the tool must create one DXF file for each section, it will use the name of the file set as prefix and the number of the section as suffix; so, for example, if you want to create a DXF file with the name Test, the tool will create as many DXF files as the sections to be exported are; so each file will be assigned with

the name of Test1, Test2, ... , Test10, etc.

Automatic editing - Shift zero on section axis The tool allows to manage the position of road axis also on a point different from zero. It might be

necessary to move all the section so to make the zero abscissa of the section coincide with the position of the road axis. Practically, the tool performs a translation, of all the abscissas of the elements inserted, equal to the abscissa of the road axis. If, for example, in a section the axis has a -3meters abscissa, then the abscissas of all the elements will undergo a -3 meters translation.

Typical sections

The typical sections builder allows to build your own typical sections by simply assembling different typologies of parametric objects; a parametric object is an object which changes its shape and working mode depending on the parameters set by the user. Any object inserted therefore possesses some properties which can be modified interactively and the result of the modification can be immediately seen on screen, thanks to the presence of a graphic cad . The parameters of the objects can have different values, according to the situations in which they are inserted; it is possible to set different values for cut

and fill situations. When an object is inserted, it can be linked to other objects or to a planimetry and/or profile polyline; in this way it is possible to design the position of certain objects (walls, ditches, etc) directly in the planimetry and/or profile graphic window and enable the typical section to follow such information.

The software is supplied with a complete library of objects which can be used in the typical sections; the

objects are defined with a wide range of variables, allowing the user to customize the object. It is however possible to design one's own typical elements directly on the graphic CAD, save them, modify

them by typical object builder and use them in the sections.

This module also allows to verify in a precise and dynamic way the typical section along any of the project axes, both during the building phase and once it has been inserted in the parametric design; moreover, also section data, values by station and planimetry and/or profile polyline data are displayed dynamically.

Here are some of the features of the typical section manager:

Visual building of the typical section.

Wide library of parametric base objects; the object parameters can be different for cut/fill situations and for right/left zone.

Base objects can be linked to each other by connection points.

Insertion and reference points can have a fixed position, be linked to other objects or be linked to a planimetry and/or profile polyline.

Dynamic, precise and real simulation of the typical section on any of the project axes.

The typical sections used in a project are automatically included in the project file. In this way, the project can be completed by any user on any computer, without having to copy the files of the typical section libraries.

Work environment

The typical section window reports in its upper part two toolbars, one with the commands for the

management of typical section and graphic window, the other with the commands for the management of display and modification modes. The rest of the window is subdivided into four main parts:

1. Objects manager: it is on the left side of the window and reports the list of all the typical section objects along with their properties and the commands for their management.

2. Objects library : it is situated on the lright side of the window and reports the list of the objects which can be inserted in the typical section, subdivided according to typology (roadways, layers, gutters, ditches, walls, generic objects) .

3. Graphic window: it is situated in the middle of the window and reports the preview of the typical section.

4. Information: it is situated at the bottom of the window and reports the information concerning the simulation of the typical section when “Typical section builder” is active , and

section data, values by station, planimetry and/or profile polylines at a certain axis station

when “Subproject simulation” is active.

Help on line: this key displays a menu by which it is possible to enter the help on line and the

information concerning the version of the typical section builder.

Bar for the management of typical section display and modication The second toolbar reports the commands for the management of typical section display and modification.

TheToolbar, in “Typical section builder” mode reports the following commands:

Change mode: By this key it is possible to pass quickly from “Typical section

builder” mode to “Subproject simulation” mode of the last axis subproject simulated.

Display: “Cut/Fill”: allows to display at the same time the section in cut and in fill, so as to simplify the check of the elements having different features in the two situations. According to the modification mode

set the active situation is displayed with coloured objects, while the non active one is displayed in grey; if

both cut and fill modifications are active, the fill situation is coloured.

Modify "Cut/Fill": if active, the changes made on the object properties are applied both to the cut and fill situations. If the visualisation “r; Cut/Fill” is active, the object is selected in both situations.

Modify "Cut": If active, the changes made to the object properties are applied only to the cut situation. If the visualisation “r; Cut/Fill” is active, the object is selected only in cut situation.

Modify "Fill": If active, the changes made to the object properties are applied only to the fill situation.

If the visualisation “r; Cut/Fill” is active, the object is selected only in fill situation.

The toolbar in "Subproject simulation” reports the following commands:

Change mode: This button allows to pass quickly from “Subproject simulation” mode to “Typical section builder” mode.

ProSt

396

Modify"Current section": If this button is active, the changes made on the project properties are applied only to the axis and to the current station and do not modify the typical section predefined values (the ones set by “Typical section builder” mode). In this way, it is possible to

modify the typical section only for some segments of the axis, without having to create each time different typical sections.

Objects manager In the management of objects it is possible to display and modify the properties of the objects inserted in

the typical section. By button it is possible to block or hide automatically the management of objects so as to reduce or widen the graphic window.

Object properties Each object contains a series of particular points and properties which determine its aspect and the way it works:

Insert point: it is the point in which the object is inserted in the typical section; the coordinates

of this point can also be obtained from a connection point released from another object contained in the typical section, from a planimetry or profile polyline, otherwise they can be fixed.

X Coordinate:

Value: It is the real value, or the value related to the axis position, the X coordinate must

assume.

Variable: The X coordinate value is obtained from a connection point released from another object contained in the typical section.

Planimetry polyline: the X coordinate value is obtained from a 3D planimetry polyline, with a specified code, on the cross section.

Y Coordinate:

Value: It is the real value, or the value related to the project elevation, the Y coordinate

must assume.

Variable: The Y coordinate value is obtained from a connection point released from another object contained in the typical section.

Planimetry polyline: the Y coordinate value is obtained from a 3D planimetry polyline, with a specified code, on the cross section.

ProSt

397

Profile polyline: the Y coordinate value is obtained from a profile polyline, with specified code, on the cross section.

X and Y coordinates can also assume different values; for example, X value can be obtained from a variable, while Y value can be a fixed value in absolute coordinates.

3. Reference point: reference points are points used to modify the aspect of an object and allow to link an object to another. For example, if we link the endpoint of a layer with the endpoint of a roadway, when superelevation and widening are applied to the roadway, also the layer will be rotated and widened. Moreover, reference points can be linked also to planimetry and profile polylines, in the same way as the insertion points.

X Coordinate:

None: X coordinate will assume the value predefined by the object.

Value: It is the real value, or the value related to the axis position, the X coordinate must assume.

Variable: The X coordinate value is obtained from a connection point released from another object contained in the typical section.

Planimetry polyline: the X coordinate value is obtained from a planimetry polyline, with a

specified code, on the cross section.

Y Coordinate:

None: Y coordinate will assume the value predefined by the object

Value: It is the real value, or the value related to the project elevation, the Y coordinate must assume.

Variable: The Y coordinate value is obtained from a connection point released from another

object contained in the typical section.

Planimetry polyline: the Y coordinate value is obtained from a planimetry polyline, with a specified code, on the cross section.

Profile polyline: the Y coordinate value is obtained from a profile polyline, with specified code, on the cross section.

As happens with insertion points, the X and Y coordinates of reference points can also assume

different values.

Connection points: Connection points are points used to link different objects contained in the typical section. Each object releases one or more connection points which can be used as

insertion points or as reference points by the objects inserted afterwards in the typical section.

Properties: object properties used to customize the shape and the way the object works, so as to differentiate it in the different situations in can be inserted in (left, right, cut and fill) or in the different typical sections.

ProSt

398

Drawing properties: Drawing properties are used to indicate which lines of the object must be drawn. This can be useful, for example, to compose the different layers of a roadway, because it

allows to merge different layers avoiding the overlapping of lines.

Groups: groups are used to merge more objects so that they can work as a single object. For

example, if we insert a layer in the group of layers belonging to “roadway” object and then we move the roadway, also the layer will be moved; so, if we delete the roadway, also the layer will be deleted. Any object can have a series of fixed groups, which therefore cannot be created, changed or deleted. Each group can contain only a certain typology of objects, for example, “roadway layers” will contain only layer-type objects.

Properties tab In the table of object properties it is possible to display and modify the object properties and points of reference, and every property is located on different levels, so as to simplify its search and use. Any object has a base level, coloured in dark grey, in which its name is displayed, and eight sub-levels,

coloured in light blue, to divide the different typologies of properties. The sub-levels are the following:

Reference points: This level contains the object insertion point and all its reference points.

Properties: This level contains all the object properties.

Draw: This level contains all the object drawing properties.

Groups: For all the possible object groups some levels are inserted, in which the group different

names are displayed.

The table of object properties is subdivided into two columns:

Name: this column displays the names of the objects, of reference points, properties and groups.

As far as insertion point and reference points a button is displayed, which allows to set the coordinates of the point by selecting it from the graphic window.

In "Subproject simulation” mode, on the left of the property name, button is displayed, which allows to open a window in which it is possible to open the property value by station or by section.

ProSt

399

By button it is possible to activate or deactivate the dynamic updating of the typical section

when moving inside the table or modying the values. By button it is possible to import the values by station of the property of another object, axis data (superelevation, widening, terrain/project elevations, etc.) and planimetry/profile polyline data.

If a property has some values defined by station, icon will be displayed in name column, and if

it is linked to a planimetry and profile polyline, icon will be displayed.

Moreover, if the property has different values between cut and fill, an asterisk (*) is inserted at the beginning of the property name.

From this window it is also possible to modify the object name by clicking on the name of the object selected.

2. Value: In this column it is possible to visualise and modify property values. In the case of the object base level, dark grey, three more buttons are active. They are the following:

Link properties : Opens the window for linking object properties.

Drawing direction : Modifies the direction the object is drawn with, that is if it is drawn rightward or leftward.

Replace file : Allows to replace the object file with another file,

keeping property values in common.

Object management toolbar This toolbar contains the commands for the display and modification of the objects inserted in the typical section. The commands are used to define the objects display mode in the table of properties, copy and

delete objects and insert such particular references as edge flags and cut/fill check points.

Display all objects: Allows to display, in the table, the properties of all the objects inserted in the typical section..

Display selected object: Allows to display, in the table, only the properties of the object selected.

It is possible to select an object both from table, by selecting the object name or one of its properties, and from graphic window, positioning on the object and pressing the mouse left button.

Parent object: allows to activate the visualization of the object properties, containing, in one of the groups, the object selected..

Properties: opens the window for the modification of the properties of the object selected.

Copy: Allows to copy an object in two different ways, which are the following:

c. Copy object: Creates a copy of the object selected.

d. Copy object and connect properties: Creates a copy of the object selected and performs automatically the link between the properties of the source object and those of the copied one. When two objects have linked properties, the modification of the source object property values

causes the automatic modification of the values of the properties in common, i.e. of the properties which have the same name, of the duplicated object.

Connect object properties: Opens the window for linking the properties of the object selected.

Delete object: Deletes the object selected.

Sort object: allows to recalculate the drawing order of the object selected, so as to use correctly the

points of reference and the extension limits.

Object information: allows to activate a description of the object selected, reporting some details concerning properties and points of reference.

Cut/Fill check point: This button displays a menu from which it is possible to set or annul the

cut/fill check point on left and on right. By defining a cut/fill check point, all the objects, on the left and on the right, will use the point indicated to verify whether they are in a cut or in a fill situation. Normally, for all the objects it is possible to check whether they are in cut or in fill on the insertion point. However, for certain objects, such as ditches, the insertion point coincides exactly with the terrain, so another point is necessary to make the test. By defining a cut/fill check point it is possible to move the check for example to the sideslope top or to the roadway edge.

Cut/Fill check point on left: allows to define which point the objects on the left of the section must use to determine whether they are in a cut or in a fill situation.

Cnacel Cut/Fill check point on left: allows to annul the cut/fill check point of all the objects on the left of the section.

Cut/Fill check point on right: allows to define which point the objects on the right of the section must use to determine whether they are in a cut or in a fill situation.

Cancel Cut/Fill check point on right: allows to annul the cut/fill check point of all the objects on

the right of the section.

Set edge flag: allows to associate an edge flag to the connection point of a typical section object. Edge flags are numeric marks from 1 to 99 which can be associated to object line vertexes and are used to extrapolate the vertex indicated in the planimetry and in the profile.

Property tab local menu If you press the mouse right button in the table of object properties, a local menu will be displayed, reporting some Toolbar commands and two supplementary functions which are the following:

Reset reference point: allows to reset the X and Y coordinates of the reference point selected, restoring the object predefined values. This function can be convenient when a mistake has been made in assigning a reference point, or when it is necessary to unlink an already assigned

reference point.

Modify object: opens the object selected in “Typical object builder”. The function is active only for the objects created by “Typical object builder” module.

Objects library The objects that can be inserted in a typical section are subdivided into libraries that can be personalised. Besides, the files contained in a library undergo a further subdivision, according to their typology (roadways, layers, gutters, ditches, walls and generic objects).

By button it is possible to block or hide automatically the objects library so as to reduce or widen the graphic window.

it is possible to create customized libraries, insert new files in the libraries, delete the fields contained in the libraries, display the files preview or their description and insert them in the typical section.

In the upper side of the object library manager a pull down menu is available, allowing to pass quickly from a library to the other.

In the middle there is a table displaying the different library files, subdivided according to their typology. To pass from one type to the other it is possible to use a pull down menu or the icons situated at the bottom of the table.

The table left column displays the object title, while the one on the right displays the file name. At the bottom of the window it is possible to display the object preview or its description.

In this window it is possible to customize some parameters for object visualisation. It is therefore possible to modify some specific data of the object, like for example:

Name: In Name text box it is possible to write the name of the object to be visualised in the table of object properties.

File: In File text box, the name of the file generating the object will be visualised.

Group: Group field allows to select from the list the group where to insert the object. If an

object is linked to another containing a group for objects of the same kind as those we are inserting, in Group field, the name of this will be proposed automatically.

Drawing direction: Used to indicate the direction according to which the object drawing is performed.

It is also possible to customize the parameters of the insertion point. By the button Select insertion point it is possible to reselect the object insertion point, while by Details button it is

possible to display and modify all the parameters of the insertion point.

The lists of the fields X Coordinate and Y Coordinate are used to select the kind of X and Y coordinates of the point, that is to find out whether they are derived from a variable, from a polyline or they are fixed values. The fields below, which vary according to the value of the coordinate field, can indicate: name of connection point, polyline code, kind of fixed value (in

Press button to insert the object.

The window of object properties will appear, where it will be possible to personalise the parameters as for the insertion into the graphic cad.

Press OK button to insert the object into the position desired or press Cancel button to stop the

insertion.

Object selection There are two methods for the selection of objects:

1. From graphic cad: To select an object from the graphic cad it is necessary to position the cursor on the object selected and, when the hand cursor appears, press the mouse left button. If there are more objects placed one over the other, a pop up menu will be visualised with the list of the objects available; from the list it will be possible to select the one desired.

2. From the table of object properties: To select an object from the table of object properties it is sufficient to select the name of the object or one of its properties.

Modifying object properties Once the object has been inserted into the typical section, in the table of object properties all its properties are displayed. To modify an object property it is necessary to:

Select the object.

Position on the line of the property to be modified.

Change the value into the one desired in Value column.

Modifying objects drawing direction Every object is drawn in the typical section with a certain direction, which normally starts from the axis

and goes outwards. However, there can be objects that must be drawn in the opposite direction, like

internal roadsides.

So, there are two methods to change an object drawing direction:

1. From the table of object properties.

2. From the window of object properties.

ProSt

Modifying drawing direction from the table of object properties 1. Select the object.

2. In the column Value of the line where the name of the object is visualised (dark grey) press

button to choose the direction desired.

Modifying drawing direction from the window of object properties

Select the object and, from the table of object properties, select the line where the name of the

object is visualised (dark grey).

From Objects menu select the item Property.

The window of object properties will appear, where in Drawing direction field it will be possible

to select the direction desired.

Press OK to make the changes

Using object reference points To create dependence and correlation among the different objects available in the typical section, some reference points are used. These points are used to modify the aspect or the characteristics of an object according to the shape or the position of a connection point of another object.

There are two methods for setting reference points:

Set from graphic cad.

Set from table of object properties

Set from graphic cad 1. Select the object.

2. Click, by the mouse left button, on the graphic cad, inside the yellow square indicating the

reference point to be moved or press , button in the table of object properties, next to the

name of the reference point to be modified. Once it has been pressed, the graphic cad will activate the selection mode and will display all the connection points, indicated by white circles,

where it will be possible to hook the reference point up. If there are more reference points placed one over the other, a pop up menu will be visualised where it will be possible to select the reference point desired.

3. Select by the mouse the connection point to hook up to - the tool will display a hatched line linking the reference point selected and the connection point we are choosing - and press the mouse left button to confirm the selection or press the right button to cancel the operation.

Set from table of object properties

Select the object.

Select the line of the reference point to be modified in the table of object properties.

Expand the properties of the reference point by pressing icon "+" on the left of the name. Select the kind of X and Y coordinates of the reference point, then assign the values desired according

to the kind selected.

Moving objects It is possible to move the objects that are in the typical section by simply changing the values associated to their insertion points.

ProSt

410

There are three methods for changing insertion point:

1. Change from graphic cad.

2. Change from the table of object properties.

Change from graphic cad

Select the object to be moved.

Click by the mouse left button, in the graphic cad, inside the white square indicating the insertion

point to be moved or press , button in the table of object properties, next to the name of the

insertion point to be modified. Once it has been pressed, the graphic cad will activate the selection mode and will display all the connection points, indicated by white circles, where it will

be possible to hook up the insertion point. If there are also some reference points placed one over the other, a pop up menu will be visualised where it will be possible to select the insertion point normally called "INSERT".

Select by the mouse the connection point to hook up to - the tool will display a hatched line

linking the insertion point selected and the connection point we are choosing - and press the mouse left button to confirm the selection or press the right button to cancel the operation. If other objects are hooked up to the same connection point it will be possible to choose whether to move them after the one we are moving (the objects will be moved to the first connection point of the object we are moving) or not.

Change from the table of object property 1. Select the object to be moved.

2. Select the line of the insertion point to be modified in the table of object properties.

3. Expand the properties of the insertion point by pressing icon "+" on the left of the name. Select the kind of X and Y coordinates of the insertion point, then assign the values desired according to the kind selected.

Linking object properties Any object that is inserted in the typical section is a new and independent object, so it can be useful to connect the property values so that by modifying an object all the objects linked to it will be modified automatically. For example, in a typical section there is normally a right roadway and a left roadway. If

we link the properties of the left roadway with those of the right roadway, it will be sufficient to modify the width of the last one that the modification will be applied also to the left one.

Any object will link only the properties having the same name as those of the object to link to; besides, any object can have its properties linked to more different objects at the same time.

Once an object has been linked to another object, the icon will be displayed on the left of the object name, and on each property an icon will be displayed, which will be used to confirm the link to the other object.

Linking object properties

Select the object and select, from table of object properties, the line where the name of the

object (dark grey) is displayed.

Press button in value column of the table of object properties or select the item Link object

properties from Objects menu


4. Select the objects to link the properties to or press None button to remove the selection from all the objects of the list.

5. Press OK button to confirm the changes or the button Cancel to cancel them.

Replacing objects If you want to change an object already inserted in the typical section, instead of deleting it, replacing it and setting again its property values, it is possible to substitute it with another one of the same kind.

This will allow to keep insertion point, reference points and the values of the properties in common with the new object; the properties are kept, that have the same name.

There are two replacement methods:

1. Replacement from table of object properties.

2. Replacement from window of object properties.

7. From the window of object properties press OK to confirm.

Copy objects There are two methods for duplicating the objects contained in the typical section.

1. Copy object: creates a copy of the object selected.

2. Copy object and connect properties: creates a copy of the object selected and performs automatically the connection between the properties of the original object and the copy. When two objects have their properties linked, the modification of the properties of the original object involves the automatic modification of the values of the properties in common, those having the

same name as the object duplicated.

Copy object 1. Select the object to be copied and select, from the table of object properties, the line where the

name of the object is visualised (dark grey).

2. From Objects menu select the item Copy and the sub menu Copy object.

3. The window of object properties will appear:

Select the object to be duplicated and select, from the table of object properties, the line where

the object name is displayed (dark grey).

From Objects menu select the item Copy and the sub menu Copy object and connect

properties.

Follow the instructions as for object duplication. Moreover, performing this kind of duplication, the object duplicated and all the objects contained in its groups will have their properties linked automatically with the original one.

Note: The duplication is performed automatically for the objects contained in the groups of the object that is duplicated, keeping their respective connections unchanged.

Deleting objects To delete the objects that are contained in the typical section it is necessary:

1. To select the object to be deleted and, from the table of object properties, select the line where

the object name is displayed (dark grey).

Set Cut/Fill check points In the typical section it is possible to select, on the left and on the right, the check point for the objects

cut/fill check. To set cut/fill check point it is necessary to:

1. In objects page select Cut/Fill ceheck point on left or Cut/Fill ceheck point on right. The graphic cad will activate the selection mode and display the connection points by white circles.

2. Indicate the connection point to assign the cut/fill check to.

The tool will automatically link to the check point indicated all the objects on the left or on the right, and

will display the mark.

Cancel Cut/Fill check point It is possible to delete, on the left and on the right, the check point used for the objects cut/fill check. To cancel cut/fill check points it is necessary to:

1. Select Cancel Cut/Fill check point on left or Cancel Cut/Fill check point on right in

objects page. The tool will automatically delete the check points on the left and on the right.

Saving a typical section

To save the changes made it is possible to use Save command or Save with name command. The

typical sections saved by "Typical sections builder”module will generate binary files with TNB extension. It is possible to integrate to these files some supplementary information, such as a title, an extended description, and also a password for modification.

To set these supplementary information it is necessary to:

From File menu select Document properties item.


Set the title of the typical section in Title text box, and the description in Description text box. If you want to protect the file that is being modified, it is possible to insert the password in

Password text box. When a password is set, during the file opening phase, a dialog box will be visualised, where you will be asked to insert it and, if the password inserted is not correct, the file will be opened only in reading mode.

Sub-base layer

OBJECT DATA

Object name Sub-base layer.

Object description Inserts a layer with its bottom not parallel to the upper layer,

but subdivided into two segments with different slopes. Normally used for sub-base layer. This layer displays a bottom subdivided into two parts as to a point called point E. With reference to this point, the bottom displays a slope towards the inside of the layer and one towards the outside of the layer. The two slopes are always negative, from point E they go down inward and outward, and

their value is influenced by the slope of the upper layer; however, their value is always equal or below the minimum

set in Minimum base slope property. The position of point E changes according to the slope of the upper layer and it moves between COURSE_START_VAR and COURSE_END_VAR reference points, so as to optimize the amount of material used to build the layer.

Point E identifies the point with the minimum layer thickness and this value can be set by Minimum thickness property

situations.







As you can see, it is possible to set the typical section parameters by two buttons, one for the first

section and one for the last. This has been conceived to let the user set different parameters for the first and for the last section, leaving to the tool the task of interpolating the values for intermediate sections.

Example: suppose you have to insert a typical section on a group of sections and you know that the road widens progressively from 3.5 meters to 4.5 meters; it is sufficient to set a 3.5 width for the first section and a 4.5 width for the last section and activate the option Interpolate properties. The tool will insert a 3.5 wide typical section for the first section and interpolate the width of the following sections as far as the last section with a 4.5 width.

Activating the option Interpolate properties allows to interpolate linearly the properties of the typical section, from the first to the last section of the group.

In case of insertion on a group of sections it is possible to choose between two different modes:

Automatic: typical sections are inserted automatically on the group of sections specified.

Step by step: the parameters for a possible modification are displayed every time a typical section is inserted. This mode is very useful when the data to specify are different in any section; in fact, it is a great time-saving device, avoiding operations that would need a long time to be performed by hand.

As you can see, it is possible to set the parameters of the typical element by two buttons, one for

the first section and one for the last. This has been conceived to let the user set different parameters for the first and for the last section, leaving to the tool the task of interpolating the values for intermediate sections.

Example: suppose you have to insert a gutter on a group of sections and you know that it widens

progressively from 0.5 meters to 0.8 meters; it is sufficient to set a 0.5 width for the first section and a 0.8 width for the last section and activate the option Interpolate properties. The tool will insert a 0.5 wide gutter for the first section and interpolate the width of the following sections as far as the last section with a 0.8 width.

Activating the option Interpolate properties allows to interpolate linearly the properties of the typical element, from the first to the last section of the group.

In case of insertion on a group of sections it is possible to choose between two different modes:

Automatic: typical elements are inserted automatically on the group of sections specified.

Step by step: the parameters for a possible modification are displayed every time a typical section is inserted. This mode is very useful when the data to specify are different in any section; in fact, it is a great time-saving device, avoiding operations that would need a long time to be performed by hand.

Note. In case a wall is inserted, the tool first inserts the wall, then it prompts you for indicating the sideslope the wall must replace; in this way the sideslope is cut and the line passes through the back of the wall inserted.

Insertion of working lines on cross sections

In order to make easier, and faster, the insertion of complicated or heavy working lines, some specific

commands have been arranged for the insertion of such elements as stripping, terrain recovery excavation, bench etc. Through the definition of specific work parameters, and after indicating the points on which the element has to be applied, the tool inserts automatically the line required.

Automatic offset

This command performs automatically the offset of an element, taking, as ends of the offset, the intersection between that element and another element. This command is useful with stripping-line elements, when it is necessary to remove a terrain layer under the embankment; in this case the tool can

perform an offset of the terrain line, limited by the two sideslope bottoms of the embankment.

Terrain code: indicate the name of the element to use as reference to perform the offset.

Project code: indicate the name of the element to use to determine the area where to perform the offset. The tool will calculate the ends of the element and perform the terrain offset only inside the area delimited by project line.

Element code: name of the element to create.

Excavation thickness: thickness of the offset to apply to terrain line.

Supplementary width on left: the area where the offset is calculated can be extended at a certain amount on the left.

Supplementary width on right: the area where the offset is calculated can be extended at a certain amount on the right.

Terrain offset: when this option is active, it performs an offset from the terrain line.

Horizontal excavation: with this option the tool will consider the terrain elevation on axis and it will apply the excavation thickness; on this new elevation a horizontal line will be drawn.

Fill sections: activate this option to perform the command on fill sections.

Cut sections:activate this option to perform the command on cut sections.

Press OK to apply the command on the group of sections indicated.

Offset: fixed-thickness element

By insertion of an offset we mean the semi-automatic construction of a line that can be used in order to

calculate such element as stripping area, wearing course, binder course, etc.

It is possible to build this line automatically, on a group of sections, or manually, section by section.

Inserting automatically fixed-thickness elements The tool performs automatically the offset of an element, taking, as ends of the offset, the intersection between that element and another element. This command is useful with stripping-line elements, when

it is necessary to remove a terrain layer under the embankment; in this case the tool can perform an offset of the terrain line, limited by the two sideslope bottoms of the embankment.

Inserting manually fixed-thickness elements The tool asks you to insert a set of points, usually belonging to a line that has already been inserted, and a thickness. So a new line is inserted with a fixed offset (thickness) from the points defined. The offset

can be vertical (applied only to the elevations), or inclined (orthogonal to the segments).

Utilities

Insertion of edge flag

By inserting a edge flag you just assign to a point belonging to a cross element, usually an extremity, a particular attribute that will be used when the tool has to extract a profile on the basis of the elevation of such particular points as ditch bottom points, head wall points, etc.

If, for example, you want to obtain in the longitudinal profile a Supplementary profile indicating the bottom elevation of the ditch, it is necessary to assign, for each section, a flag to the bottom ditch point. By Profile extraction it is then possible to obtain automatically the profile of the ditch.

A point having a edge flag is easy to distinguish because a little flag, containing the numeric value assigned to that point, is drawn near it. To remove the flag it is sufficient to activate that command giving 0 as numeric value.

Through this window it is possible to choose the group of sections on which to insert the flag. You then have to decide on what element to insert the flag, specify the numeric value to be assigned

and the position of the point to which the flag has to be assigned.

Insertion of sideslope flag

By inserting a sideslope flag you just assign to a point belonging to a cross element, usually an

extremity, a particular attribute that will be used when the tool has to insert a sideslope automatically.

For example, the tool uses this flag also to generate a Planimetry of project. In order to recognize the road edges, the tool searches the points with this flag.

The points which have a sideslope flag are easy to find because near the point a little asterisk is drawn. To remove the flag it is sufficient to activate the same command.

By this command, you can specify the State of Progress start and final elevations. If in Cross-sections properties the option Elaboration with S.O.P. is active, two horizontal lines will be drawn on the two

elevations given. The tool will then calculate only the areas between the two elevations.

The command can be activated in one of the following modes:

Menu Sections > Volumes > S.O.P. position

Command line: SETSAL

On CAD command line the following questions will appear:

Set S.O.P. position Cursor/Manual/<C>: By cursor the tool asks you to indicate the S.O.P. elevation by the mouse, while by manual mode the tool asks you to insert the two S.O.P. elevations.

Setting by cursor Enter start elevation of S.O.P.: Indicate by the mouse the start elevation of the S.O.P. Enter final elevation of S.O.P.:

Command line: CALCULATE

Visualization of volume calculation results on section

It is possible to visualize directly on the graphic CAD the data calculated concerning the elementary areas

and the widths. If, in the section, something has been modified, we suggest you to perfom the recalculation of the elementary areas before executing this command.

The command is activated by selecting the item Totals on screen from Sections menu, or give TOTALS command.

Command line: TOTALS

On the CAD command line, the data calculated for each element present in the section will appear. In the

CAD window, the areas calculated are also highlighted so as to show to the user the result of the operation.

Calculated areas can be exported directly into Opera, the tool for work accounting, by using Genius system, which allows the dynamic transfer of data between the two programs.

Display calculation results on section

It is possible to display directly in the graphic CAD the data calculated as far as elementary areas and widths. If any changes have been made in the section, it is recommendable to perform a recalculation of the areas before executing this command.

The command is executed by selecting the item Totals on screen from Sections menu, or by TOTALS

Volumes

Volume calculation by sections

Volume calculation is carried out by two methods: by average end area method and by equalized area method. On the basis of the data derived from the calculation of the elementary areas of the sections, it is possible to extract, for each area, the elementary figures (triangles and trapezia) that constitute it and are indispensable to carry out the calculation. The partial distances between the sections are obtained by

ProSt

534

the Table of longitudinal profile. Besides volumes, the procedure can return the values of the surfaces calculated both in projection and length. It is also possible to exclude from the calculation segments representing typical elements (ex. bridges, tunnels, etc.)

Volume and area calculation on sections can be performed by considering the position of the figure barycentre compared with the axis. In this way, quantities on curve are considered with more precision.

Before performing the calculation it is better to make sure that the data which are indispensable for the elaboration have been inserted properly. Many mistakes can be made. For example, it is possible you do not insert the stations of the sections, of course obtaining as a result volumes and sections equal to zero.

Remember that volume calculation is performed on the basis of the data derived from the management of the cross sections. So, before performing the calculation, make sure the tables of Section codes have been compiled.

Calculation requirements can be summed up as follows:

check of the stations of the sections in the table of the longitudinal profile

indication of the segments of project to be excluded from the calculation

Now, it is possible to perform the calculation: How to perform volume calculation. From the window of volume calculation management it is possible not only to perform calculation, but also to display and obtain calculation results.

From volume and area calculation, the tool can generate Bruckner diagram, which allows to study how cut and fill volumes alternate along a road. Bruckner Diagram .

The volumes calculated can be exported directly to accountancy tool Opera by using Genius system, which allows the dynamic transfer of data between the two tools.

ProSt - Standard

ProSt - Standard: Road, railway, hydraulic design

By ProSt Standard it is possible to design roads, hydraulic works and any other linear work; the project includes the geometry annotation performed according to topographic surveys or existing maps, the management of terrain and project longitudinal profiles and the length of cross sections with volume calculation. The design can be performed with policy check and includes sight check. “Dynamic design” provides for the updating of all the elements and project data following any kind of modification.

Calculation of volumes and accounting sections

The possible typologies of section management and accounting are so different k that very rarely a software can automatically adapt to them. ProSt Standard is the most advanced and complete solution available in the market today, since it has no limits in the accounting of sections of every kind and size,

thanks to the variety of the customization opportunities it offers. ProSt Standard allows the definition, completely free and manageable by the user, of the list of workings contained in the section ( terrain, project, stripping line, terrain recovery, wall, etc.), of the list of quantities required by the accounting (cut, fill, topsoil, etc.) of the measure unity (width, area, volume, etc.) and of the list of the calculation tips by which the user informs the software about how to use the workings to obtain the quantities to account.

Once the rules have been defined, ProSt carries out the elaborations set, calculating areas, surfaces, volumes, lengths, quantities, allowing to decide the paging up of the single sections, dimensioning, tables, automatic hatches, to achieve reports of volume calculation and paging up of complete sheets.

The data inserted, the calculation procedures used and the results obtained are reported in detail, both in

the sections drawing and in the printouts. Volume calculation is performed both by average end area method and by equalized area method, with the opportunity to consider the position of the areas barycentre as to the axis, thus improving calculation precision in the curves. The tool offers the

opportunity to exclude the segments on which the calculation is not to be carried out, for example those containing artworks.

It is possible to carry out volume and area calculation also by steps (as far as the elevation of the first S.O.P. or between two S.O.P. ). Thanks to Genius technology, volume calculation results can be automatically transfered to Opera, the software for work accounting. Besides the restitution of the quantities calculated, for each axis it is also possible to obtain a summary with the final sums, considering all the axes involved in the project.

Bruckner diagram

From volume calculation ProSt can produce Bruckner diagram, or mass diagram, as far as cut and fill volumes. Bruckner diagram is completely customizable and can be either printed or inserted in a drawing

sheet.

Sight diagram

ProSt Standard includes sight check and the generation of the corresponding diagram; sight diagram is a

graphic which reports on X axis the stations and on Y axis the stopping distance calculated according to the speeds taken from the corresponding speed diagram. This diagram then reports the sight distances verified; in this way, the areas where the stopping distance exceeds the sight distance, i.e. areas where sight is not granted, can be easily detected. The test can be performed by setting all the variables to be considered. For example, it is possible to set, in the same diagram, the stopping distances for different maximum speeds (to verify whether speed limit should be reduced in some segments) or the sight

distance for different lanes (internal lane, external lane).

For each sight distance to calculate many other parameters can be set, such as the height and the distance of the point of view, obstacle height and distance, colour, linetype, etc.

ProSt Standard not only generates the diagram but can determine automatically the widening in curve that can grant the sight; such widening can be set directly on typical section shoulders so as to create automatically a project satisfying sight requirements.

ProSt

550

The sight distance, and the widening that can grant it, is calculated by using a 3D model of the road. That 3D model is generated automatically according to alignment, vertical design (optional) as well as according to the typical section geometry and size.

It is in fact possible to create a simplified typical section and specify such parameters as lane width, height and size of the obstacles(guard rails, new-jersey, walls, etc.) according to the alignment station.

Generating a 3D model of the road is the only way to make sure that, for the sight test, all project parameters have been considered simultaneously.

Determining sight distance can either be limited to the alignment or include also altimetric elements; if an only-planimetric test is performed, the model will be generated on a completely horizontal plane, while, if a plano-altimetric test is performed, the model elevations consider the altimetric design as well.

The final diagram can be customized with all kinds of dimensioning and can be printed directly on plotter/printer or exported in DXF/DWG format.

Sight Diagram

Introducing sight diagram

According to the M.D. of 5th November 2001, for a project to be approved, it is necessary to grant the “complete accomplishment” of the rules it indicates: should this not happen, and should the project propose solutions contrasting the directions provided for by the law, it becomes necessary to consult the

Council of Public Works or Regional Superintendency, depending on the kind of road being designed, once the safety analyses required have been carried out.

This obviously means that respecting the Decree represents a must in the design process. One of the most critical tests is the one concerning sight distance, in which the free sights required to grant safety have to be compared to the ones actually available in the road alignment.

Therefore, studying sight, along with other geometric parameters, is a fundamental step in defining a project, while its conclusions, reported in a specific table, become an indispensable element in the course

a project must follow to obtain the Agency approval.

Testing the sight distance in designing new infrastructures or in renewing the old ones, can be a very useful tool for testing the safety of existing infrastructures, since it allows to determine the parts of the road alignment in which the reduction of the sight distance can cause a great number of accidents.

Sight is a very complex problem, involving different project variables: the existing territorial limits impose choices which, although respecting the minimum parameters imposed by the law, according to

dynamic dimensioning parameters ( minimum horizontal radius), do not necessarily grant the sight in curve, which is influenced also by the size and geometry of the cross section as well as by the presence of obstacles (barriers, walls, tunnel piers, etc.)

Therefore, it is not necessarily true that an alignment complying with the dynamic geometric parameters

required by the policy automatically grants the sight distance; on the contrary, to pass this test, it is necessary to carry out further and more detailed analyses, taking into account more variables.

ProSt-Standard is the solution for the sight check and the generation of the corresponding diagram; sight diagram is a graphic which reports on X axis the stations and on Y axis the stopping distance calculated according to the speeds taken from the corresponding speed diagram. This diagram then reports the sight distances verified; in this way, the areas where the stopping distance exceeds the sight distance, i.e. areas where sight is not granted, can be easily detected.

ProSt - Standard not only generates the diagram but can also automatically determine the widening in

curve necessary to grant the sight; such widening can be applied directly to the typical section shoulders, allowing to produce automatically a project which respects the sight required.

The check can be performed setting all the variables one wants to consider. For example, it is possible to produce, in the same diagram, stopping distances for different maximum speeds (so as to verify whether in some segments it is better to reduce speed limit) or the sight distance for the different lanes (internal lane, external lane). For each sight distance to be calculated it is possible to set many other parameters,

such as height and distance of point of view, height and distance of the obstacle, colour, line types, etc.

ProSt

551

The calculation of the sight distance and of the widening necessary to grant it is performed by using a 3D model of the road which is generated automatically, according to the horizontal alignment, the vertical alignment (optional), as well as according to the typical section geometry and size. It is in fact possible to create a simplified typical section and specify such parameters as roadway width, obstacle height and size (guard rails, new jersey, walls, etc.) according to the alignment station.

Generating a 3D model of the road is the only way to make sure that all project parameters for sight check are considered at the same time. Determining sight distance can be limited to the mere horizontal alignment, or extended to the vertical alignment as well; if a only-horizontal check is performed, the model will be generated on a completely horizontal plan, while if a plano-altimetric check is performed, the model elevations will take into account the vertical design too.

The final diagram is completely customizable with all kinds of dimensioning and it can be printed on plotter/printer or exported in DXF/DWG format.

Work environment

The module for sight diagram generation can be activated as follows:

Menu Axis > Checks and diagrams > Sight diagram

Command line: VISGRAPH

Once the module has been activated, the following window will be displayed:

ProSt

552

The window for diagram calculation is subdivided into two parts; on the left side two pages are available, Diagram and Model, reporting the data to be used for calculation, while on the right side two other pages are available, Sight diagram and Sight diagram data, reporting and displaying calculated data.

In Diagram page a table is available, reporting distances, comparisons and widening to

calculate, and displays in the lower side the number of triangles of the model used used for calculation.

In Model page it is possible to generate or select the model to use for calculation.

Sight diagram page displays the diagram of sight distances calculated and some supplementary calculations, with the opportunity to select the alignment direction and to perform a print preview.

In Sight diagram data the data calculated are reported in table form:

On the left top of the window it is then possible to select the axis subproject where to perform sight distance checks.

Add sight distance

To add a sight distance it is necessary to press button of Diagram page on the left side of the

window, and then select the item Sight distance. The following dialog box will then be displayed:

In this window it is possible to define the parameters and the features of the sight distance to insert in the diagram.

In Description field a description can be inserted of the sight distance to be displayed both in the

diagram line table, on the left side of the window, and in the diagram column keys in the print preview.

In Property page the properties are set, for generation and display of the sight distance.

In Line group it is possible to insert:

Feed step: Indicates the step according to which to perform the calculation of the sight distance

along the road alignment. The value set influences both diagram accuracy and calculation time. If

ProSt

553

we set a low value as feed step, for example 5-10 meters, the diagram will be very accurate but, on the other hand, with a very long road alignment, 10-20 km, calculation time will be very long. So, in order to avoid long calculation time, it is necessary to choose a feed step according to the length of the segment to verify as well as according to the accuracy to be obtained. The values normally assigned to this parameter vary from 10 to 50 m.

Line Color: indicates the color with which to display the reference line in the diagram.

In Search group it is possible to set some parameters to optimize sight distance calculation:

Search minimum distance: Indicates the distance from which to start verifying the sight

distance compared to the current search position determined by the feed step. This parameter, therefore, indicates the minimum distance an obstacle is expected to be found at. This parameter mainly influences the diagram accuracy, since the higher its value is, the more

probable the possibility will be to exclude possible obstacles. The value is normally equal to the

feed step.

Search maximum distance: Indicates the distance from which to start verifying the sight distance compared to the current search position determined by the feed step. This parameter, therefore, indicates the maximum distance an obstacle is expected to be found at. This

parameter mainly influences diagram calculation speed and normally it is better to set it on a value slightly higher than the maximum reference distance to verify. For example, if we want to verify the stopping distance of a road alignment it is better first to calculate this reference distance and then use a value slightly higher than the value calculated as Maximum search distance of sight distances.

By the option Add speed diagram vertexes it is possible to integrate the check points determined by

the feed step with the speed diagram points, thus performing some sight checks on sight diagram

vertexes stations.

In Control points page the parameters are set, which are necessary to determine the position of the driver and of the obstacle to use for sight distance calculation.

In the group Start point the parameters are set, to determine the position of the driver's eye.

ProSt

554

Offset from axis: indicates the distance of the driver's eye from the road axis; according to the current policy, it must be set in the middle of the lane occupied. The arrows indicate the offset

direction, so:

o Offset to the right of the line of march.

o Offset to the left of the line of march.

Height from road level: indicates the elevation of the driver's eye from the roadway; according to the current policy, it must be set at a height of 1,1 m.

In the group Start point the parameters are set, to determine the position of the obstacle:

Offset from axis: indicates the distance of the obstacle from the road axis; according to the current policy, it must be set in the middle of the lane occupied by the driver in case of stopping

distance, in the opposite one in case of passing sight distance and in the adjacent one for change

lane sight distance. The arrows indicate the offset direction, so:

o Offset to the right of the line of march.

o Offset to the left of the line of march.

Height from road level: indicates the height of the obstacle from the road axis; according to

the current policy, it must be set at a height of m. 0.1 for stopping distance, and m. 1.1 for passing sight distance.

The tool calculates automatically also the widening to be set to the shoulder in order to grant a sufficient

sight distance; for this reason, in the group Excluded area for widening calculation an area must be set, where sight distance reductions are due only to the vertical alignment and therefore cannot be solved by a widening of the shoulder. Normally, this interval starts from the axis and ends at the

beginning of the shoulder. For example, in case of a hump on horizontal straight, sight distance is reduced but it cannot be modified by changing the shoulder width, but only by modifying the hump vertical curve.

In the group Excluded area for widening calculation are then set:

Start offset from axis: indicates the distance from the road axis where the exclusion of

widening calculation starts.

End offset from axis: indicates the distance from the road axis where the exclusion of widening calculation starts.

ProSt

555

In Start and End page the interval is set, within which to perform sight distance calculation.

The intervals for sight distance calculation can then be:

Full axis: calculation is performed on the whole road axis.

Start and end station: calculation is performed within the interval set by start and end station.

Start and end section: calculation is performed within the interval set by start and end section.

In Property page the general parameters are set, for display and generation of reference distance.

In Line group it is possible to insert:

Feed step: Indicates the step according to which to perform the calculation of the reference distance along the road alignment. The value set influences both diagram accuracy and

calculation time. If we set a low value as feed step, for example 5-10 meters, the diagram will be very accurate but, on the other hand, with a very long road alignment, 10-20 km, calculation time will be very long. So, in order to avoid long calculation time, it is necessary to choose a feed

ProSt

step according to the length of the segment to verify as well as according to the accuracy to be obtained. The values normally assigned to this parameter vary from 10 to 50 m.

Speed limit: The speed used to calculate reference distance is the one obtained from speed

diagram. However, by filling this field it is possible to set a speed limit, below project speed limit, so as to reduce reference distance granting in this way the sight necessary.

Line Color: indicates the color with which to display the reference line in the diagram.

The option Use axis vertical alignment allows to perform the calculation of the reference distance both considering and ignoring the longitudinal slope of the road alignment.

The option Add speed diagram vertexes allows to integrate the calculation points determined by the feed step with the speed diagram points, thus performing the calculation of the reference distance on speed diagram vertexes stations.

In Start and End page the interval is set, within which reference distance is calculated.

The intervals for reference distance calculation are then:

Full axis: calculation is performed on the whole road alignment axis.

Start and end station: calculation is performed within the interval set by the start and end station.

Start and end section: calculation is performed within the interval set by the start and end

section.

Roadway model

In order to obtain a higher precision in creating the sight diagram of a road model, sight distance check is performed on a triangle mathematical model. This can be either an existing model (survey of an existing road, model obtained from a planimetry of project, etc.) or generated automatically from typical sections.

ProSt

560

Create model from typical sections The model to use to create a sight diagram can be generated automatically from typical sections, making it unnecessary to insert the sections along the axis, calculate them and generate a planimetry of project.

This allows to verify sight distances by starting simply from the road axis, and gives the opportunity to perform some checks before the project is finished.

Moreover, it is possible to generate the model taking into account or ignoring the road axis vertical alignment, so as to verify both the horizontal and vertical sight or only the horizontal one.

Besides, for a correct generation of slopes and other elements of the typical section, it is possible to decide whether to use an existing terrain model, simulate one, or not use a terrain at all.

Set geometric properties In order to generate the alignment model to verify it is possible to use the information concerning the

variables defined in the section properties. By these variables it is possible to set beforehand, on a specific table, the typical sections to use and the values of some of their properties (roadway width, roadside width, sideslope slope, etc.) according to the station.

To display the window of geometric properties it is necessary to:

Press the button of Model page on the left of the window.

Select the item Geometric section properties... . The window of geometric section properties

will be displayed.

Set the variables and values desired.

Close the window.

Set codes The typical section used to generate a road mathematical model could be made up of different section lines, of which only a part are of some interest for sight check: In order to indicate what lines to use to create the model it is necessary to:

1. Press button of Model page on the left of the window:

2. Select the item Section elaboration codes... . The window of section elaboration codes will be displayed.

3. Set the values desired.

Note: Table fields are the same as those defined for planimetry of project

4. Close the window.

Create a model After setting the section geometric properties and the codes of the lines to be used it is possible to pass

to the creation of the road mathematical model. To create the model from typical sections it is necessary to:

Select the option Create model from typical sections of Model page on the left of the window.

Define typical file from geometric section properties: Indicates that the name of the file of the typical section to use to generate the model is obtained from the variables of section geometric properties.

Select typical file: Indicates the name of the typical section file to use to generate a model.

Use simplified typical sections: For sight distance calculation and check it is sufficient to use simpler sections than those normally inserted in typical sections for area and volume calculation. For this reason, it is possible to define inside the same typical section a "normal" section, containing all the objects and

calculation lines, and a "simplified" one, containing only some objects, less detailed, in order to obtain only the pavement. Therefore, by using simplified sections it is possible to generate a model constituted only by the objects causing sight reduction, avoiding in this way the generation of very complex models which would slow down calculation and might cause mistakes. So, activating this option the simplified versions of the sections will be used to create the road model.

Terrain elevations: by this option it is possible to define whether the creation of the road model must

take into account the presence of a terrain or ignore it. The different options for the calculation of terrain elevations are the following:

None: the model is generated ignoring the presence of a terrain, therefore such objects as sideslopes will not be generated.

Cross sections: the model is generated by simulating the terrain as a horizontal line situated at

the terrain elevation defined in the sections.

Terrain model: the model is generated by using as terrain model an existing model.

Band to be calculated: Indicates the width of the terrain band in case it is used to create the model.

Terrain model: Indicates the subproject where the triangles of the terrain to be used to create the model are available.

Note: Terrain calculation from model is performed only on triangle models.

Step model construction: Indicates the step according to which to insert the typical section for the

creation of a triangle model. The tool, moreover, inserts automatically some typical sections on specific points of the alignment (curve start and end, superelevation variation intervals, etc) and on the points where sections typology changes.

Use axis vertical alignment: Indicates whether to use or not the vertical alignment of the axis defined by the grade lines and vertical curves in the profile.

Use superelevation and widening: Indicates whether to apply to the typical sections, in generating the road mathematical model, the superelevations and widening defined in Superelevation and widening window.

Press button of Model page on the left of the window to start generation procedure. The triangles generated by creating the model from the typical sections are saved with diagram data; it is possible to display the number of triangles generated at the bottom of Diagram page on the left side of the window.

Export a model into a subproject In order to display the road mathematical model, generated by creating the model from typical sections, it is necessary to copy triangle models inside a survey subproject, and then:

1. Press button of Model page on the left side of the window. A window for destination subproject selection will be displayed.

2. Select destination subproject and press Select button to confirm the selection or Cancel to stop it. This will delete all the triangles in destination subproject. The following window will then appear:

3. Press Ok to stop copying the triangles of the model generated or No to annul the operation.

Use existing model If sight diagram calculation must be performed on a surveyed model or on a model generated by planimetry of project it is necessary to perform the following steps:

1. Select the option Use existing model of Model page on the left side of the window.

2. Select from the list of models the survey subproject containing the triangles on which to perform

sight distance check.

Sight diagram calculation

Once the sight distances and the reference distances to calculate have been inserted and the model on which to perform the calculation has been selected, it is possible to pass to the sight diagram generation.

To generate the sight diagram, the model selected must contain some triangles; it is possible to verify this just by checking the number of triangles reported at the bottom of the Diagram page, on the left side of the window.

Table of sight diagram lines

Sight distances, reference distances, comparisons and widening are inserted in the table of diagram lines in Diagram page. these four kinds of lines and calculations are then subdivided into the following four groups:

1. Sight distances: This group lists the sight distances calculated or to be calculated.

2. Reference distance: This group lists the reference distances calculated or to be calculated.

3. Comparisons:This group lists the comparisons between the sight distances and the reference distances.

4. Widening: This group displays the widening to apply to edges so as to grant proper sight.

In the first column of the table the descriptions are displayed, of diagram lines and comparisons. These descriptions are the ones set on inserting the line or the comparison and can be modified by following the instructions reported in the section concerning Sight distances, reference distances and comparisons.

The columns marked by the letters D and T are active only for sight distances, reference distances and

comparisons, and they indicate:

D: Indicates whether to display or not sight distances and reference distances in the comparison diagram.

T: Indicates whether to display or not the values of sight distances reference distances and

comparisons in the table reporting the data calculated.

areas where the sight is inferior to the reference one.

In order to activate or deactivate the coloration of the comparisons press button of the toolbar displayed above data table.

If the stopping distance test is not passed for altimetric reasons, symbol will appear in Altimetric

sight column.

Calculated widening According to the comparisons, the tool calculates automatically the widening to apply to the shoulders, so as to grant the sight distance necessary to have the reference distance considered in the comparison

respected. The tool calculates, for each line of march, an internal widening, to apply, if necessary, to the median, and an external one, to apply to the external unpaved roadside. In order to calculate the widening more precisely, in sight distance properties it is necessary to set accurately an exclusion

interval, which is due to the road vertical alignment. The widening calculated can be displayed directly in the diagram table and imported into the widening tables so as to be used by the typical sections.

Import widening After performing diagram calculation, for each comparison the widening calculated is displayed. In order to perform the import of the widening into the widening tables it is necessary to:

1. Select the roadway to which to assign the widening from diagram line table in Diagram page.

2. Press button of the toolbar situated above widening table. The following window will be displayed:

By this window it is possible to set some parameters to perform the importation of the widening calculated by comparison.

The field Import mode indicates how a widening must be imported into a table. The possible methods are the following:

1. Delete previous values: importation replaces previous values, so the values of the existing widening are deleted and the new ones are inserted.

2. Complete and replace previous values: The values imported complete the table values and replace the ones with the same station.

3. Complete and add previous values: The values imported complete the table values

and are added to the ones with the same station.

Definition of area calculation sequence in the sections

Note. This section is active only in ProSt-Standard configuration. In ProSt-Basic calculation rules are fixed and allow to account the following quantities: cut, fill, gutter, ditch, pavement layer and wall,

stripping and terrain recovery excavations, wall excavation, wall subbase and trench.

The definition of area and section calculation sequence is activated as follows:



In the appearing dialog box select Calculation sequence page for the management of the sequence to use to calculate the areas.

ProSt

574

The base principle of the calculation of quantities follows the sequence of cut and fill operation so as they are made. The calculation of quantities is performed by extracting from the section two elements at a time (inserted as lines) and by calculating the areas between the two lines; therefore, two quantities are obtained, one of cut, the other of fill.

For example, suppose you have a terrain line as begin code and a project line as work code. The tool calculates a cut area in those parts where the project is lower than the terrain and a fill area in those

parts where the project is above the terrain line.

Every line in the table corresponds to an elaboration; for each line the following data are required:

Start code. Code of the element to be used as start line for the calculation of areas. You will have to apply to this line the line defined in the following field. If, no value is assigned the line resulting from the elaboration of the previous field will be considered as start line. The possible codes are listed in Lines tab.

Work code. Code of the element to be used as work line for the calculation of areas. This line is applied to the start line. The possible codes are listed in Lines tab.

Work type. In this field it is specified whether the operation performed on the start line is a cut or fill operation. As a consequence, a new line is generated, and it is called resulting from the fusion between start line and work line. This line will be used in the next elaboration.

Down - Minimum profile the resulting line will be made up of the start line and of those segments of work line where elevations are lower than those of the start line. As a result, you obtain a line that represents the

minimum profile of the two lines.

Up - Maximum profile the resulting line will be made up of the start line and of those segments of work line where elevations are above those of the start line. As a result, you obtain a line that represents the maximum profile of the two lines.

Under. Request for a code defined in Areas tab (Areas to be calculated). To this code the cut area obtained by calculation will be assigned.

Over. Request for a code defined in Areas tab (Areas to be calculated). To this code the fill area obtained by calculation will be assigned.

Mem. Allows to memorize the result of the cut and fill operation so that it can be used in a following line both as start line and as work line. The result of the elaboration can be saved in one of the other elaboration lines or it can be saved with a number from 1 to 9; in this case, to retrieve the working in column Start code or Elaboration code it is necessary to repeat the number preceded by the character ":".

ProSt

575

Draw. If in Mem column the result of the elaboration has been assigned to another elaboration line, this line might be inserted in the sections drawing and then be used, for example, for dimensioning. In this way the tool can generate lines which are not drawn but derive from area calculation.

Calculation of single elements The tool can calculate, for every single section, also areas (wall cutting, pavement layer, topsoil, etc.), lengths (non-woven fabric, compaction, etc.) and widths (wearing course, binder course, etc.). In order to calculate these elements you have to set as Start code the code of the line to be

elaborated. Nothing has to be specified concerning Work code and in the column Work type it is necessary to set one of the following values:

Area. the area will be calculated, of the line whose code is specified in Start code cell. Length. the length will be calculated, of the line whose code is specified in Start code cell. Length No V.Seg. the length will be calculated, with the exclusion of the vertical segments,

of the line whose code is specified in Start code cell. Horiz.Length. the horizontal length will be calculated, of the line whose code is specified in

Start code cell. Num.Vertexes. the number of vertexes will be calculated, of the line whose code is specified in Start code cell. Quantity. the number of lines will be calculated, whose code is specified in Start code cell.

In Under cell it is necessary to indicate the code of the area in which the calculation result is memorized. The possible codes are listed in Areas tab (Areas to be calculated).

Clicking on button Preview, it is possible to check directly the correctness of calculation sequence settings without having to close the tab and perform command Totals on screen.

Instead, Create button activates a guided procedure which collects information concerning the different

lines to account and the relationships between them. By this procedure, completely guided and interactive, also the unexperienced user who is not keen on the method the tool uses to calculate volumes, can easily obtain the results desired.

An example of how to fill Elaboration codes tables

In order to learn how to use the tables, suppose you have to calculate some sections containing the following elements:

terrain line

project line

pavement line

stripping line

terrain recovery line

backfilling of terrain recovery line

According to the price list, the following quantities will be calculated:

cut and fill area

pavement width (plane width)

stripping width

terrain recovery area

backfilling of terrain recovery area

ProSt

576

The table of the elements to be inserted will be defined as follows:

The table of areas to calculate is defined as follows :

You can see how cut and fill, terrain recovery and backfilling report Area as work type, while pavement and stripping report Plane width.

ProSt

577

The table for area calculation sequence is the following:

Line 1: TER terrain line is used as start line and PRO project line is used as work line; as work type you

have to set Down - minimum profile. The tool intersecates the two lines (terrain and project) and from this intersection it memorizes the minimum profile represented by the two lines; besides, the cut area, determined by the possible project line under the terrain, is memorized as under area with CUT code. Over area is not assigned.

Line 2: as start line is now used the line resulting from the calculation of line 1 (that is the minimum profile between the two lines); as work line the stripping line is used. Again, the tool takes into

consideration, for the following elaborations, the minimum profile between the two lines intersecated. The

under area, determined by the intersection of the two lines, is memorized with STRIP code, and the area width is extracted from it. Over area is not assigned.

Line 3: as start line is used again the line resulting from the previous elaboration (terrain minus project excavation minus stripping excavation) while as work line the terrain recovery line is used. The work type is set again as Down - minimum profile. The under area calculated is computed as terrain recovery area TREC while over area is not assigned.

Now all the cut operations to be performed in the section are finished; fill operations have to start.

Line 4: the line that results from the elaboration of line 3, representing the bottom line of all excavations, is used as start line. As work line the backfilling of terrain recovery line BFILL is used. In this case the work type is set as Up - maximum profile, thus obtaining, from the intersection of the two lines, the line with the biggest profile. The over area calculated is assigned as backfilling of terrain recovery area (BFILL code), while under area is not assigned.

Line 5: as start line the line is used, that was elaborated on the preceding elaboration, that is the line of

maximum profile between the excavation bottom line and the backfilling of terrain recovery line. As work line the project line PRO is considered, that was used on line 1 and is now recalled in order to calculate the fill area. As work type again the maximum profile has to be considered. The over area resulting from the intersection between the two lines is assigned to the fill area FILL, while under area is not assigned.

Line 6: this line is used only for the calculation of the pavement, which is situated above the project line. As start line is then assigned project PRO and as work line the pavement PAV. As work type the Maximum profile is assigned, even if , being this the last line, this value is not important, since the

resulting line will not be used by any other elaboration. Under area is not assigned while over area is assigned to the pavement area PAV, from which the length will then be extracted.

Even if some work lines are not available, the tool performs area calculation in any case, ignoring the lines where they are recalled.

Filling areas calculation table is of the utmost importance, since it is in this table that you determine how areas must be calculated. After setting a calculation table, it is better to test the accuracy of the

calculation, by carrying out the calculation of section areas (CALCULATE command) and to verify the calculated areas by Totals on screen command from Sections menu. It is not necessary to check all sections but only some of them in order to verify if data are set to produce the results needed.

Guided creation of calculation sequence

Note. This section is active only in ProSt-Standard configuration. In ProSt-Basic calculation rules

are fixed and allow to account the following quantities: cut, fill, gutter, ditch, pavement layer and wall, stripping and terrain recovery excavations, wall excavation, wall subbase and trench.

The calculation sequence by which the tool can then calculate areas, surfaces and quantities can be prepared automatically by a new guided procedure collecting the information about the different lines to account and the relationship between them.

The procedure, completely guided and interactive, enables also the unexperienced user, who is not

familiar with the method the tool uses to calculate volumes, to obtain the desired result.

The procedure is based on the principle by which some lines stand for cut elements, some other lines stand for fill elements and others for the pavement layer. These lines can be associated to the corresponding areas, which, in most cases, have also the same code and are therefore cut areas, fill

areas, and pavement areas.

The purpose of the procedure is to enable the user to define these couples of lines-areas in the exact sequence they are carried out with; according to the main sequence, cut elements must be performed

first, then the cut is gradually filled and finally comes the pavement layer.

Bruckner diagram

Bruckner diagram, or mass diagram, is very important for the development of a road design, because it

clearly shows how cut and fill volumes alternate along a road, so that it is easier to locate building yards and to decide how to perform the leveling compensation, which consists in carrying terrain from cut areas to fill areas.

Mass diagram reports on X axis the alignment stations and on Y axis the sum of the terrain volumes from the origin to the section considered.

In Bruckner diagram it is also possible to specify the maximum distance of earthwork by operating machine from a cut area to an adjacent fill area. The tool will then display the diagram areas in which this

operation can be carried out and return the volume to move.

The command can be activated by one of the following methods:

Menu Sections > Volumes > Bruckner diagram

Command line: BRUCKNER


Cut area code: code of cut area.

Fill area code: code of fill area.

Diagram: in this group it is possible to choose the color to represent cut segments and fill segments with. The option Fill areas allows to display / hide the colour backfilling under the curve of volumes. The

In the group of options Movement distance it is possible to specify the maximum movement distance available. By activating the option Display, the tool identifies in the diagram the areas where such distance can be applied. All the areas of passage between bigger cut volume to bigger fill volume and vice versa are analyzed; these areas are limited according to the maximum movement distance defined, thus obtaining a start and end station and a volume of material to move.

By activating the option Labels, the diagram will report, for any area identified, the area start and end station and volume.

ProSt - Premium ProSt Premium extends ProSt Standard with a set of tools to solve easily and precisely all the problems concerning the planning of road intersections, from a simple At-Grade intersection to very complex interchanges, rotary intersections, etc. ProSt Premium includes specific functions for the survey and design of tunnels as well as a set of commands for the calculation of the repavement elevations of existing roads.

Road Intersections

ProSt Premium includes a sophisticated system for the management of intersections which, thanks to a new methodology, allows a more complete and precise management of every kind of intersections, from

roundabouts to crossroads and interchanges.

Planning these situations with the classical methods (offered by most of the programs for road design) demands a long time and a lot of resources, while the final result is not always precise.The commands introduced by ProSt Premium allow a real and considerable reduction of the time you need to develop complex projects and let the technician take up the planning with the certainty of a quick and precise final outcome.

To turn the work of days into the work of hours or even of minutes is possible today thanks to ProSt

Premium. Such innovative concepts, as multiple sections and the projection of alignment polylines on the profile, allow to carry out the project having constantly the graphic information concerning the other axes that make up the road intersection. ProSt Premium not only simplifies the study and the planning, but offers interactive and functional tools for a fast and precise accounting of sections presenting intersections, avoiding in this way the double or triple computing of volumes in adjoining sections.

Planning at grade intersections

The design of at-grade intersections for crossroads and roundabouts is performed by using typical intersection schemes for the drawing of edges and islands or by using existing polylines, which is particularly useful when it is necessary, for different reasons, not to have tangent points between the roundabout edges and the edges of intersection axes.

In the longitudinal profile of the different axes that make up the intersection some references are automatically positioned, concerning the stations and the intersection elevation of interfering axes;

project grade lines can then be linked to them.

The sections found in the intersection area are automatically broken and made perpendicular to the two external edges; in this way, the sections will be displayed at best and also volume calculation will be precise.

The whole intersection will develop in 3D (it is not a simple 2D drawing) with the generation of the final

model and with the minimum number of axes: in fact, it is not necessary to create specific axes for in/out lanes.

Road intersections builder for road intersections

ProSt Premium offers a work environment in which it is possible to define standard intersection types

complete with edge curves, widening, islands; such typical intersections can be saved and used in different projects; in this way, it is not necessary to draw each time the elements that make up the intersection, since it is sufficient to select the typical intersection desired and this will be inserted in the current project. Even a such a complex intersection as a roundabout can be easily defined and saved as a typical intersection.

Interchanges, in/out lanes and lane division

For the design of interchanges, and, in general, for the design of in/out lanes, two specific intersection typologies are available: in/out lane and lane division, which allow, by setting a few parameters, to develop completely and in 3D the whole intersection; in fact, the software can insert linked sections in

the secondary axis and display in the profile the project elevations to be used to keep aligned in elevation the sections of the two interfering axes. Moreover, the tool calculates the best section cut line, allowing the generation of an absolutely precise and complete 3D model.

ProSt

595

Multiple sections

Multiple sections allow to display, for each section, the corresponding right and left sections of other axes but also of the same axis (useful in case of hairpins, the design of downhill sections incercepts that of the uphill ones). Displaying multiple sections allows to set a relationship between sections belonging to different axes both for study and check purposes, and to generate compound drawings of specific parts of the alignment.

Check policy concerning intersections

Policy checks have been introduced both for at-grade intersections ( simple intersections and roundabouts) and for in/out lanes of interchanges.

For every at-grade intersections sight triangles are generated; for roundabouts deflection angles are verified to check the trajectory deviation while crossing the intersection. For in/out lanes

the different segments which make them up are studied and tested: acceleration/deceleration lane length, maneuvering lane length, inflow lane length and curve stretch.

Projection of axes on profile

Projecting polylines or axes on the longitudinal profile allows to obtain a polyline by projecting, on the profile itself, another axis or a polyline of planimetry. In this way it is possible to visualise on the profile the altimetric proceeding of other axes or of the edges of other axes, so as to set correctly the altimetric planning of the current axis.

Profile from polyline

ProSt Premium includes a command allowing to extract a terrain and project profile from a planimetry polyline; project elevations are those of the polyline vertexes, while terrain elevations are automatically calculated by the digital model. This command is particularly useful in generating profiles that correspond to areas in which to insert such works as walls, shoulders, etc; in fact, according to the polyline which represents the road edge, it is possible to generate the corresponding profile, to be used in the design.

Creating parametric object types

In order to extend object type libraries with its own objects, ProSt includes a specific environment where it is possible to create or turn fixed type objects into parametric objects, that is objects which can change

their shape and size according to some defined parameters. In this environment it is possible to draw, or

transform from an existing drawing, one’s own object type and create properties linked to different segments of the object; for example for a wall it is possible to create a property called “Wall base” and link it to the segment representing the base of the typical element. Assigning a value to “Wall base” parameter, the segment will automatically assume the corresponding length.

Moreover, thanks to the programming environment it is also possible to define, for example, the proportion between wall base width and wall height.

The entity can be saved and become a library object to be used either in the typical sections or directly inside the sections.

Renew – Repavement

In road design it is often necessary not only to widen but to repavement or modify existing roads. As far

as the cover of the existing pavement, normally a minimum layer (overlay) of new material must be kept and this is precisely what ProSt Renew commands deal with. ProSt Renew commands can set a relationship between the project horizontal alignment, the edges of the existing horizontal alignment and the survey model of the current situation; from the analysis of such data, a profile polyline is calculated, which will represent the ideal project elevation to keep the minimum layer required. The issue may seem a trivial one, but it is not so if we consider that modifying a horizontal alignment can change the position

of the project axis compared to the existing one and, therefore, the determination of the project

ProSt

596

elevation must take into account the existing terrain , of the new axis position as well as of the transversal slopes.

Tunnel

The presence of tunnels, both in the topographic survey and in road design, is in some way a specific situation which cannot be dealt with and managed by traditional modes. From the topographic survey of existing tunnels (with points situated both in the upper and in the lower side) it is possible to obtain the tunnel 3D model and cross sections.

A specific dimensioning type is also available, which identifies the thickness differences between the

existing shape (terrain) and the project templates.

Introducing intersection manager

About intersections

Managing intersections allows to solve quickly and under every aspect (planimetry, profile and sections) every kind of intersection. The management does non provide for the horizontal design of the axes involved, which must already be present in the project; by the parameters defined for each intersection,

the tool arranges some information, graphic and not, which is then used by the different procedures for section calculation and generation of project planimetry. In particular, dynamic design can manage, for each intersection, the data defined in the intersections and regenerate edge polylines; here starts the application of typical sections on the axes and the building of the project planimetry as well as of the final project model.

The method consists in defining in the planimetry the axes that make up the intersections, define the

altimetry of the main axes, define the typical sections to be used and assign the different typologies of typical sections to the intersections found, so as to obtain automatically the drawing of edges and canalization islands.

For at-grade intersections and roundabout intersections it is possible to solve the intersection by using edge polylines that can be inserted and defined even if they do not come from a typical intersection. From such information it is possible to obtain the planimetry of project and the project final model.

By Parametric design it is possible to manage all the phases of the intersections design.

Intersection types


AT-grade intersection By linear AT-grade intersection we mean all those intersections which are

performed between two axes, when neither of them is a roundabout, with an angle of incidence between 40° and 160°. For angles of incidence below 40° or over 160° it might be necessary to manage the intersection as a lane entry/exit.




Lane entry/exit: it is when a secondary axis converges or streams out (parallel or not) of a main axis. To be used, for example, in interchanges for lane entry /exit.

Lane division: it is when an axis ends and continues on two separate axes.

Intersections (ProSt - Premium)

Intersections page allows to manage every kind of intersection in a project: AT-grade intersections, Roundabout intersections, lane entry/exit and lanes division.The window allows the insertion and

management of intersections, the modification of parameters and policy check.

The window is subdivided into three main blocks:

Intersections list: the left side reports all the intersection nodes inserted. The intersections can be arranged in groups according to the area on which they operate.

Properties, Verify and Settings: on the central block are displayed all the parameters regulating

calculation, drawing and the way the intersection node selected works. Check page reports the values calculated by the policy and the comparison with the project values.

Typical intersections: on the right side it is possible to define, only for AT-grade intersections (linear or on roundabout), the possible typical intersection to be used to build edge polylines.

General information about intersections

Managing the intersections allows to solve in 3D and from every point of view (planimetry, profile and sections) every kind of intersection. The management does not provide for the horizontal design of the axes involved, which must be already present in the project; by the parameters defined for each intersection the tool supplies some information, graphic and of other kind, which is then used by the different procedures of section calculation and generation of project planimetry.

In particular, dynamic design can manage, for each intersection, the data defined in the intersections and regenerate edge polylines; the application of typical sections on axes starts here, as well as the construction of the project planimetry and of the final project model.

Intersection types


AT-grade intersection By linear AT-grade intersection we mean all those intersections which are performed between two axes, when none of the two is a roundabout, with an angle of incidence between 40° and 160°. For angles of incidence below 40° or over 160° it might be necessary to manage the intersection as a lane entry/exit.

The drawing of intersection edges can be obtained by inserting a typical intersection; it is also possible to

solve the intersection by using edge polylines that can be inserted and defined even if they do not come from a typical intersection.



Lane entry/exit: it is when a secondary axis converges or streams out (parallel or not) of a main axis.

To be used, for example, in interchanges for lane entry /exit.

Add intersection: the command allows to define a new intersection in the project. The new intersection can create a new group of intersections or be included in an existing group.

Delete Intersection: the command allows to delete a group of intersections.

ProSt

598

Add secondary axis: the command allows to add a new axis to a group of existing intersections. It is better to use this command only to add a new intersection axis to the intersection group of a roundabout.

Remove secondary axis: the command removes an intersection node from a group of

intersections.

Note: Removing the intersection axis does not remove the axis but only the information concerning the axis inside the intersection (typical intersection, automatic drawing of edges, etc.)

Rebuild intersection: the command activates the intersection rebuild procedure; the operations performed depend on the kind of intersection.

which to cut the cross sections of the two axes; the cut is necessary to delete the overlapping areas. The cut is limited to the external part of the axes sections, where they overlap.

In the secondary axis longitudinal profile the profile polyline is calculated, which represents the

projection of the main axis elevations; the polyline will be used to calculate the project elevations which will assure the continuity of the road surface.

The polyline is completed with a grade line segment, whose slope is that of the last polyline segment calculated; the grade line represents the start element of the design concerning the remaining part of the lane entry/exit.

Lane division

The intersection Lane division is formed by three axes: the main axis which ends and subdivides into two new axes called Reference axis and Intersection axis.

In the longitudinal profile of the reference axis a reference is inserted, reporting the final elevation of the main axis; moreover, a grade line segment is inserted, representing the

continuation of the longitudinal slope in the final segment of the main axis. In this way, it is possible to complete the design of the reference axis preserving the continuity with the main axis.

In the longitudinal profile of the secondary axis a reference is inserted, reporting the station and the start elevation of the reference axis. Moreover, another reference is inserted, reporting the station and the elevation of the reference axis on the point where the division of the two axes shoulders occurs.

When it is impossible to use a typical intersection it is possible to solve the intersection by defining the polylines which determine the edges shape in the intersection zone; the polylines must be planimetry polylines whose codes are among the ones provided by the tool for the left and right edges. By settings page of parametric design it is possible to manage the name which must be attributed to the polylines

representing the two edges of the intersections.

Since edge polylines can belong to either axes, it is necessary to verify whether the option Share polylines with other axes is active for both axes, otherwise the tool could be unable to find the polylines necessary to the solution of the intersection. The option Share polylines with other axes is managed as Axis properties filter.

Recalculate cross-section on intersection area: by this option it is possible to activate, in the intersection areas, an automatic modification of cross sections which makes them perpendicular to the right and left edge. Therefore, in the intersection area the section is no longer represented as perpendicular to the axis , but broken into a right and a left side: the right side will be perpendicular to the intersection right edge and the left side will be perpendicular to the left edge. Also the transversal

length of the sections reflects this situation and will be calculated as perpendicular not to the axis but to the edges. The following image shows how the cross sections are displayed on the intersection.

Volume calculation itself has been adapted to the new shape of the cross sections and an adjustment factor has been introduced to obtain a very precise calculation of the intersection zone areas and volumes. Volume calculation report displays the adjustment factor used in determining the totals.

Lane division management

It is the case in which an axis ends and continues on two distinct axes.

To manage this kind of intersection it is necessary to have three

axes:

4. the main axis, which ends and from which the other two axes start. The situation could also be the opposite: the main axis starts where the other two axes finish.

5. The reference axis, which is the first to be designed after the main axis. The project direction must follow the traffic direction.

6. The secondary, or intersection, axis, which is the last to be projected, since its elevations depend on the reference axis. The project direction must follow the traffic direction.

The design sequence on which the system is based is the following:

planimetric definition of the three axes

vertical design of the main axis

insertion of the Lane division intersection and generation of the intersection; the generation adds

some information in the reference axis profile, which are necessary for the vertical design.

According to the generation, the reference axis will have all the information necessary to complete the vertical design.

Introducing at grade intersection design

The new method for at grade intersection design allows to define intersections inside the project, so as to obtain the automatic design of edges and canalization islands.

This information, together with the generation of the planimetry of project from typical section, allow to

obtain automatically the planimetry of project and the 3D model of three-leg intersections, four-leg intersections and roundabouts.

The new method consists in defining in the planimetry the axes that form the intersections, their vertical alignment, the typical sections to use (by using Parametric design), setting the different kinds of typical intersections to the intersections and from this information obtain the planimetry of project and the final model of the project.

Typical intersection builder

By typical intersection builder module it is possible to build a road intersection model by putting together different objects (horizontal curves, three-center curves, triangle traffic islands,teardrop islands, etc.)

The model built can be inserted directly into ProSt horizontal alignment by intersections (definable in

Road intersection template management module), so as to simplify and speed up the drawing of edges and of all the objects involved in road intersections.

The objects inserted are parametric, that is to say, characterised by specific properties, and can be modified interactively. The result is immediately visible on display, thanks to a graphic CAD. The modules built by typical intersection builder module can then be used in different intersections, so it is possible to build a library of typical intersections to use in the different project situations.

The module can be activated as follows:

By Intersection preview group it is possible to set the parameters for simulating the axes in the graphic window of typical intersection builder. The field Intersection type indicates the type of

intersection to be defined: Three-leg intersection, Four-leg intersection or Roundabout leg. In case of roundabout legs it is possible to define the roundabout radius in Roundabout radius. By Intersection angle field it is possible to simulate the angle of the intersection between the two axes, so as to set correctly the horizontal curve radiuses of the intersection edges; moreover, the scroll bar

allows to simulate its value dynamically.

In Main axis group it is possible to define the area of the intersection on the main axis by defining with the fields Before intersection point and After intersection point respectively the point where the intersection starts (by setting its distance before intersection point) and the point where the intersection finishes (by setting its distance after intersection point).

In Intersection axis group it is possible to define the area of the intersection on the intersection axis by

In case of three-leg intersections and of roundabout legs it is possible to define only the distance before intersection point.

Objects page In this page it is possible to display and modify the parameters of the objects that constitute the typical intersection. Any object is made of a set of particular points and properties that determine its drawing.

Position: This property indicates the position of the object related the main axis and/or the

secondary axis, or the position along the reference axis related to the intersection point.

Reference points: There are objects that can depend from other objects in the intersection. In order to perform these references the objects must have at least a point of reference enabling

Correlated insertion of sections

The correlated insertion allows to insert sections on an axis determining their position according to the position of other sections on other axes. This command has to be used whenever you have an intersection of different axes, such as ramps, crossroads, etc. In fact, after positioning, by the ordinary methods, the sections on the principal axis it is possible to position the sections on the secondary axis, so that their position can be correlated to the sections of the principal axis. Correlated means that, in order to calculate the position of the new section, the tool will calculate the intersection point between the two

sections and will make the ratio between the two distances, D1 and D2, of the intersection point between two axes, have the value desired.

Inserting the sections in a correlated mode is a very good help to the correct development of road intersection planning; in fact, having correlated sections it is possible to obtain exact multiple sections

and also the calculation of project planimetry and of volumes will be precise, being performed on the intersection points themselves. By inserting correlated sections it is also possible to obtain automatically

an alignment polyline to be used as cut line.

The command is activated in one of the following modes:

Toolbar: Road intersections

Menu: Axis > Cross-Sections > Correlated insertion

Command line: SSEC

In the CAD command line the following questions will appear:

Ratio between section distances <1>: Indicate the ratio between the distances of the two sections from their intersection point; with values different from 1 the intersection point must be brought nearer to one of the two axes.

Insert alignment polylines on intersections Yes/No/<N>: If you answer Yes the tool will create an alignment polyline having as vertexes the intersection

points of the correlated sections.

Multiple sections

One of the most important functions introduced by X module is undoubtedly the management of multiple sections. By the word multiple section we mean the possibility to visualize, for each section, a section on its right and one on its left. The side-sections can belong both to other axes but also to the same axis; just think how useful this function can be in the design of hairpins, when, in planning the downhill section, you have to know how the sideslopes of the uphill sections are.

It is possible to specify the side-sections by filling the columns of a table or use a semiautomatic mode that gives the graphic selection of the sections that are situated on the right or on the left.

To obtain the correct visualization of the side-sections the tool uses two distinct modes:

ProSt

637

Rotation: the intersection point is calculated, between the two sections and it is used as rotation point of the lateral section along the line defined by the main section; by this method the real dimensions of the lateral section are maintained.

Projection: the lateral section is projected on the line defined by the main section; in this way, the exact dimensions of the lateral section are not maintained.

The side-sections that are visualized have the only purpose of being a reference for the main section so as to study the possible cutting of the elements; in fact, seeing the shape and the position of the lateral section, it is possible to determine the position of the cut line, beside which to delete the elements that overlap the other section. The sections cutting is a fundamental phase in the development of complex projects because it allows to calculate exactly the project areas and volumes avoiding overlapping zones

where they would be computed twice.

Being references, the elements of the side-sections are not dimensioned in the drawing dimensioning and they are not considered for calculating the areas of the sections. However, it is also possible to choose to import the elements of the side-sections into the main section; after the import, the new elements are actually elements of the section and as such they are dimensioned in the dimensioning and considered in the calculation of the areas.

The command starting the dialog box of the multiple sections can be activated both by planimetry graphic

module and by the sections graphic module; the praxis in general is similar, but there are some functions that are active according to the module where the command is performed.

There is a specific filter for visualizing multiple sections. By activating or de-activating this filter, multiple sections are made visible or invisible. The filter can be activated from Cross-sections properties - Drawing filters tab

ProSt

638

Navigation among multiple sections (correlated) From the sections graphic window it is possible to pass to the display of the left and the right correlated

section. In cutting and verifying the correlated sections it is always necessary to display the correlated left and right section; by pressing a single button now it is possible to display the section required.

: displays in the graphic window the current section right correlated section.

Multiple sections from Planimetry

The management of multiple sections can be started from planimetry graphic module in one of the following modes:

Road intersections Toolbar

Menu Axis > Cross-Sections > Multiple sections

Command line: SZMULTI


In Subproject check list it is possible to specify the subproject for which you want to define multiple or lateral sections.

The table in the window is divided into three parts:

Left sections: on this side the sections are specified, which are on the left of the main sections; for each main section it is possible to specify the section that is visualized on the left. To identify the section to be visualized it is possible to choose a belonging axis and then the section number.

Current axis: the central column defines the main sections of the axis now selected in Subproject selection list.

ProSt

639

Right sections: on this side the sections are specified, which are on the right of the main sections; for each main section it is possible to specify the section that is visualized on the right. To identify the section to be visualized it is possible to choose a belonging axis and then the section number.

Therefore, compiling the table fields, it is possible to define manually the lateral sections to be visualized. It is also possible, however, to compile the same fields in a semiautomatic mode, using Select buttons.

There are two Select buttons, one on the left sections, the other on the right sections, according to the button activated you will compile either the fields concerning the right sections or the fields concerning the left sections.

Activating Select button the dialog box is closed and you pass on to the graphic visualization, where the following questions are asked:

Select the section of the current axis: select the section of the current axis with which you want to associate a side-section.

Select section on the left / right of current axis: select the corresponding section that must be visualized on the left/right.

The above questions are repeated, allowing to specify for different sections the corresponding side-sections. To interrupt the questions press ESC button or the mouse right button.

Once the sections selection is finished, the dialog box shown before, where the table fields concerning the left or the right side are compiled, is visualized again.

By Close button the command execution comes to an end.

Multiple sections from Cross-sections

The management of multiple sections can be started from section graphic module in one of the following

modes:

Road intersections Toolbar

Menu Sections > Multiple sections

Command line: SZMULTI


ProSt

640

The table in the window is divided into three parts:

Left sections: on this side the sections are specified, which are on the left of the main sections; for each main section it is possible to specify the section that is visualized on the left. To identify the section to be visualized it is possible to choose a belonging axis and then the section number.

Current axis: the central column defines the main sections of the axis now selected in Subproject check

list.

Right sections: on this side the sections are specified, which are on the right of the main sections; for each main section it is possible to specify the section that is visualized on the right. To identify the section to be visualized it is possible to choose a belonging axis and then the section number.

Compiling the table fields it is therefore possible to define manually the lateral sections to be visualized. It is also possible, however, to compile, from Planimetry graphic module, the same fields in a semiautomatic mode, using Select buttons.

Settings By Settings button it is possible to set some parameters concerning the visualization of multiple sections; the following dialog box will appear:

In Line codes to import check list, it is possible to specify what elements of the lateral sections must be visualized; in this way it is possible to avoid drawing elements that are not important for the design.

Keep original layers: activating this option the elements of the lateral sections are visualized with their original colors and linetypes.

Select layer: activating this option it is possible to select a layer where the elements of the lateral

sections will be saved. The elements will be visualized with the layer colors and linetypes. In this way it will be easier to distinguish the elements of the lateral sections from the elements of the main sections.

Type of projection: there are two modes according to which the visualization of the lateral sections is calculated:

View rotation: the intersection point between the two sections is calculated and then used as rotation point of the lateral section along the line defined by the main section; in this way the real dimensions of the lateral section are maintained.

ProSt

641

View projection: the lateral section is projected along the line defined by the main section; in this way the real dimensions of the lateral section are not maintained.

Press OK button to confirm the setting of data and Cancel to stop the modifications.

Importation The elements of the lateral sections have the purpose of being a reference for the project of the main

section and as such they are not dimensioned in the drawing dimensioning and they are not considered for calculating the areas of the sections. However, it is also possible to choose to import the elements of the lateral sections into the main section; after the import, the new elements are actually elements of the section and as such they are dimensioned in the dimensioning and considered in the calculation of the areas. To start the import procedure press Import button.

ProSt

642

The tool asks to indicate the group of main sections where to perform the importation:

After defining the group of sections press OK button to start the importation. At the end of the operation it is possible to see how the elements of the lateral sections are now elements of the main section, dimensioned and calculated as such.

Note. Be careful not to perform the import operation more than once, since the following importation does not eliminate the effects of the first one, and so you might have a lot of overlapped elements, and there might be, as a consequence, wrong results as far as the calculation of areas and volumes.

Calculation of axes intersection on profile

The calculation of axes intersection on profile allows to obtain a reference on the drawing of the longitudinal profile; the reference is calculated according to the intersection between the axis the profile is referred to and another axis or between this axis and an alignment polyline.

It can be useful, in general, whenever you need to obtain the intersection between the axis and a planimetric element; in case of underpasses or overpasses, for example, it is very important to know the altimetric elevation in the intersection point of the two axes, so as to choose the project elevation of the underpass or of the overpass. Another example can be that of the pipeline crossing the axis designed; in

the altimetric planning, it can be useful to know the exact position where the crossing takes place, so as to consider it properly.

The command is activated by one of the following modes:

Menu Profile > References by intersections

Command line: AINTERSECT

ProSt

643


In the group of options Intersection it is possible to specify the elements the current axis must be intersected with.

Axis to intersect: select the axis the intersection must be performed with; select this option even if you want to intersect the current axis with an alignment polyline. In fact, alignment polylines belong to the axis subproject, not to the whole project.

Intersect with an axis polyline: activate this option if you want to perform the intersection of the current axis not with another axis (previous option) but with an alignment polyline.

Polyline to intersect: select the code of the alignment polyline to be intersected with the current axis.

Arc-Chord distance: this value is used in horizontal curves to set the degree of precision by which to calculate the intersection point. It represents the maximum distance allowed between the segment approximating the curve (chord) and the curve itself. The smaller the value, the more precise will be the references calculated.

In the group of options called Symbol, it is instead possible to specify the characteristics of the reference to be calculated:

Symbol to use as reference: by Browse button choose the symbol by which to represent the intersection calculated. See Selection of symbols/blocks.

Layer: name of the layer where to save the symbol.

Press OK to start calculation.

There is a special filter for the visualization of references. By activating or deactivating this filter the

references are made visible or invisible. The filter can be activated from the dialog box called Longitudinal profile parameters in Drawing filters tab.

Projection of polylines or axes on the profile

The projection of polylines or axes on the longitudinal profile allows to obtain a profile polyline by projecting, on the profile itself, another axis or an alignment polyline. In this way it is possible to visualize on the profile the altimetric progress of other axes or of the edges of other axes, to be able to set correctly the altimetric planning of the current axis.

ProSt

644

Let's take, for instance, the classical exit ramp; after planning the main axis by the traditional methods, it is necessary to calculate an alignment polyline, as alignment offset, using the option Axis. In this way you will obtain an alignment polyline overlapping the ramp axis; the polyline elevations, however, depend

on the main axis. As far as the altimetric design of the ramp, it is possible to calculate the projection of the alignment polyline on the profile itself, obtaining in this way an profile polyline that indicates the

exact elevations the ramp altimetry must start with.


Menu Profile > Profile polylines > Polyline by axis projection

Command line: APROJECTION


The following parameters can be set:

Polyline to create: name of the profile polyline to be calculated.

Axis to project: name of the axis subproject to be projected on the profile of the current axis; select

this option even if you want to project on the current axis an alignment polyline. In fact, alignment polylines belong to the axis subproject, not to the whole project.

Polyline to project: name of the alignment polyline to be projected on the profile of the current axis.

Maximum search distance: maximum value of distance between the current axis and the axis to be projected or the polyline to be projected. When the distance of the axis to be projected or the polyline to be projected exceeds the value set, the tool interrupts the profile polyline that has been calculated, taking it up again, in case, in a different point of the axis.

Search area: by this option it is possible to set the area where to perform the projection:

ProSt

645

Right and left: the elements (polylines, axes) are projected both if they are on the right and if they are on the left of the current axis.

Right: the elements (polylines, axes) are projected only if they are on the right of the current axis.

Left: the elements (polylines, axes) are projected only if they are on the left of the current axis.

Horizontal straight feed step: feed step to be used along the horizontal straights to set the points

where to perform the projection.

Arc-Chord distance: this value is used in horizontal curves to calculate the feed step on the curve itself; in other words, to see at what intervals to calculate the projection. The tool calculates the step so that the arc-chord distance is below or equal to the value set; so, the feed step is directly proportional to the arc-chord distance. To have very precise polylines it is therefore necessary to use a small value of arc-chord distance.

Press OK to start the command.

Extract planimetry polyline profile

By this command it is possible to extract a terrain and project profile from a planimetry polyline; project elevations are the elevations of polyline vertexes, while terrain elevations are automatically calculated from the digital terrain model.

The command can be used in generating the terrain/project profiles corresponding to the areas in which to insert such elements as walls, shoulders etc; according to the planimetry polyline representing the road edge it is possible to generate the corresponding profile to be used to design the typical element.


Menu Axis > Alignment polyline > Extract polyline profile

Command line: EDGEPROF

Once the planimetry polyline from which to obtain the profile has been indicated, the following window will appear:

ProSt

646

The procedure transforms the polyline into an axis that can be saved in a new subproject or in an existing subproject, as long as it is empty. Along the axis some sections are positioned, at a distance that can be set by the user.

The profile that will be generated will have as the sections project elevations the elevations interpolated from the polyline and as terrain elevations the result of the interpolation of the polyline on the reference

terrain model.

Axis subproject: by this group of options it is possible to create the polyline profile on a new axis subproject or on an existing subproject, as long as it is empty.

Reference axis: represents the axis that will be used as reference in case the option On reference axis is activated. By this option sections are inserted automatically and the reference distance considered is the one calculated on the reference axis, not on the polyline.

Cross-section step: insertion distance between sections.

On reference axis: by activating this option the tool inserts the sections calculating the distance not on the polyline but on the reference axis set. In this way it is possible to obtain a profile where sections have a fixed step referred to the main axis. This possibility, along with the option that allows to obtain the profile dimensioning as to a reference axis, allows to generate longitudinal profiles of lateral elements (e.g. walls) with a dimensioning referred to the main axis.

Terrain model: subproject containing the digital terrain model from which to calculate the profile terrain

elevations.

Terrain offset: this value represents an offset distance from polyline on which to calculate terrain elevations. In other words, terrain elevations can be calculated either on the polyline by setting 0 as offset value, or by considering a supplementary distance from the current position of the polyline.

Open profile graphic window: by activating this option the tool, once calculation has been performed, opens the graphic window of the profile calculated.

Cut lines

The cross sections cut lines are vertical lines, one on the left, one on the right of the axis, which allow to

perform the automatic or manual cut of cross sections. The sections cutting operation performs a breaking off of the section elements along the cut line, eliminating, as a consequence, all the elements that are on the left or on the right of it.

Why is it necessary to perform a cutting on the sections? In case of road intersection planning, when some axes gradually move away from other axes, so much that they become independent, there are sections that have some surfaces in common. If the situation is not modified, this will lead to an overestimation of the volumes calculated. By the management of multiple sections it is possible to see

the sections that have surfaces in common and by the cutting it is possible to stop the development of the sections on the side developed by other sections.

Cut lines can be:

inserted manually: using, for example, the visualization of multiple sections it is possible to set the cutting position and carry out the manual cut.

calculated as alignment polylines: cut lines can be calculated automatically, by defining in the planimetry, as alignment polyline, the position of the sections cut line. See also Correlated insertion of

sections. From the calculation of the cut lines it is also possible to perform the automatic cut of sections.

Cut lines are memorized as information concerning the section so that, if the typical section must be inserted again, it is not necessary to recalculate the cut lines, since it is sufficient to perform the automatic cut of sections. The position of the cut lines can be inserted also in the table of longitudinal profile (S.O.P. tab / Cut lines).

It is also possible to remove the cut lines which are no longer necessary.

Manual insertion of cut lines

This command allows to position the cut lines on the sections and, at the same time, to carry out the cutting on the elements. The section line inserted is kept memorized in the section, so that it can be used subsequently, for the automatic cut of sections.

ProSt

647

The automatic cut of sections is usually performed along with the visualization of the multiple sections, which allow to choose the right point where to carry out the cutting.

Command line: SZINSCUTLINE

The following questions will be asked:

Enter position of cut line: Indicate a point where the abscissa is set as position of the cut line.

Select cut side: Indicate the side, according to the point indicated before, to be eliminated.

The section is cut along the position indicated and the section memorizes the new position of the cut line.

The position of the cut lines can be inserted also in the table of longitudinal profile (S.O.P. tab / Cut lines).

Calculation of cut lines

The position of cut lines can be obtained automatically, according to the position of an alignment polyline

as to the sections axis. The tool must then verify whether the section intersects the alignment polyline and calculate the distance between the intersection point and the section axis; the distance stands for the abscissa of the cut line.

An alignment polyline can have been drawn manually, obtained as offset or obtained automatically by the correlated insertion of cross sections. In general, it is therefore possible to obtain cut lines from a planimetric information.

From the automatic calculation of the position of cut lines it is also possible to pass on to the automatic cut of the sections along the cut lines.

The command can be activated by one of the following modes:

Automatic cut of sections

The command called Automatic cut of sections allows to cut automatically the sections using cut lines inserted or calculated before. Each section memorises the position of the cut lines, so it is possible to carry out this command automatically, without having always to specify the cutting position; so, even if there are different insertions of a typical section in the sections, the cutting is automatic in any case, since it is based on a predefined cutting position.

Cut Polylines

It is possible to define some planimetry polylines representing the sections cut lines. On inserting the typical sections and on generating the project planimetry the tool can consider the cut lines and at the same time cut the exceeding part. This function is very useful in designing interchanges ramps, since it allows to define in the planimetry the cut line that determines the automatic elimination of overlapping

areas between the main axis and the ramp.

References from alignment polylines

The calculation of the references from alignment polylines allows to obtain a reference (symbol) inside

the cross sections; the reference is calculated according to the intersection of the section with an axis or with an alignment polyline.

It can be useful, in general, whenever it is necessary to obtain the intersection between the section and a planimetric element; take for example a pipeline crossing the axis sections; in this case it is extremely

important to know the elevation of the intersection point between the section and the polyline, so as to verify the elevations of the excavation.

Setting elevation to edge polylines

After drawing all the planimetry polylines that define the road intersection from a planimetric point of view, it is necessary to assign elevations to polyline vertexes. In this way, the drawing of the intersection

becomes a 3D drawing.

Elevations can be assigned in three ways:

By setting start and end elevation

By using a reference axis and its transversal slopes calculated

Using an axis or a 3D reference polyline and setting manually the transversal slopes.

Calculating the elevation of edge polylines by setting start and end

elevation

Start and end elevations of polyline vertexes are set by this command; the elevation of intermediate vertexes will be interpolated. The command can be performed on all the polyline vertexes or only on a segment of it.

Calculating edge polyline elevations by using a reference axis

By this command, the elevations of planimetry polyline vertexes are calculated by using a reference axis

Entity type to measure It is possible to check the distance between two axes, between an axis and a planimetry polyline or between two planimetry polylines; select the option desired.

Entity to measure According to the kind of entity to measure (axis-axis, axis-polyline, polyline-polyline) the tool allows to select the axis subprojects or the polylines on which to carry out the check. Axes can be selected from

the list or from the graphic window by using button; planimetry polylines can be selected only from

the graphic window again by button.

Feed step: feed step along the axis or the reference polyline to determine the frequency of the check.

Maximum search distance: maximum distance between the two elements compared, beyond which the distance must not be considered.

Calculate station on reference axis: by this option the station calculated is not the station along the

reference polyline but the station along the reference axis:

Reference axis: axis on which to calculate control station.

Check Check minimum distance: activate this option to make sure the distance between the entities

compared is not below a certain value.

Minimum distance: minimum distance to be checked between the two entities.

Check maximum distance: activate this option to make sure the distance between the entities compared is not above a certain value.

Maximum distance: maximum distance to be checked between the two entities.

List only condition overpassing: when this option is active the tool will display not all the stations on

which the measure is taken, but only the stations where the condition set is not respected.

Draw lines between measured entities: this option allows the automatic drawing of the lines between the two entities near the stations on which the check is carried out.

Layer: layer the drawing lines are assigned to.

Parametric Typical objects

Creating parametric type objects

The module for defining type objects allows to create parametric objects to insert in typical sections. These objects can either be generated inside the module for defining type objects or drawn in the graphic

window of section module, using section elements with a code, and then be imported and modified.

In this module it is possible to generate different kinds of properties and connect them to the segments that make up the object. It is also possible to add some reference points and some connection points and assign them to any of the object vertexes.

For any object some interpolation tables can also be defined, to correlate the values of its properties.

It is also possible to write TANGO code to calculate the formulas and the expressions to be assigned to the values of some properties, or to make selections according to the values of some properties.

Note. Some functions contained in this module are available only to the users of ProSt Premium

Module for building parametric typical objects The module can be activated in one of the following ways:

Menu Sections > Typical elements > Typical objects builder

From module Typical sections builder

menu File > Typical objects builder

Command line: DEFOBJTYPE

ProSt

671

A window like the following will appear:

The window is subdivided into two main sections: on the left side there is the management of object properties, variables, interpolation tables, object polylines, while on the right side there is a graphic window displaying the object preview and a text editor for its TANGO code.

Creating, modifying, saving objects: commands for the general management of the object.

Management of object properties: in this tab it is possible to create, modify and delete object properties, reference points, connection points and object groups.

Management of object variables: in this tab it is possible to create, modify and delete object variables.

Management of interpolation tables: in this tab it is possible to display and modify the values of the interpolation tables of object properties.

Management of object polylines: in this tab it is possible to manage the drawing of the elements that make up the object.

Tango Code: it is possible to add the object a program code called Tango, so as to customize the value to link to the segments through formulas, selection of values and much more.

Drawing an object and inserting it in Typical objects builder module It is possible to draw an object in the sections graphic window and then insert it in typical objects manager module to make it parametric or to save it as a typical object.

The command can be activated through the following methods:

Menu Sections > Typical elements > Save typical element

Command line: STYPE

ProSt

672


Select elements: select the section elements that make up the object to save.

Select insertion point: indicate the object insertion point.

Note. To be saved as typical object, an object must be drawn not with generic drawing polylines but with section elements marked by a code.

Note. Walls are particular typical elements, since they cause the modification of the sideslope where they are inserted. Of course, the tool cannot know, for each kind of wall, how the sideslope is going to be modified. So, besides the wall line, it is necessary to draw also a line with $1 code; this line will represent the new shape of the sideslope, once the wall has been inserted. For example, in case of

retaining walls, the $1 code line must follow the wall back as far as it meets the existing ground. When

the elements to save are selected, it is necessary to select also the $1 code line. In the table of Section Codes no $1 code is available; it is necessary to insert it in the table before drawing the line.

A window resembling the following will then appear:

In this window it is possible to set the object typology, its name and a description linked to it.

Press OK to continue. Then, the window of Typical objects builder module will appear; inside it there are the elements that constitute the object.

Now it is necessary to select all the elements that make up the typical element to save.

675

The following dialog box will appear, allowing to set snap and grid of the graphic window.

Managing object variables

In this tab it is possible to generate, modify and delete object variables. Variables are similar to properties but they are not displayed in the table of object properties, so they cannot be modified directly

from "Typical sections builder" module. The values of Real number type variables can be linked to a segment of the object, as with properties, and they can also be used to contain the results of some operations among the properties of the object itself. Variables, unlike properties, have only one value and therefore are not influenced by the position of the object insertion.

In the table of variables all the object variables and the system variables of the sections are displayed in two different groups:

Object variables: In this group all the object variables are displayed.

Section variables: In this group the section system variables are displayed and the values given

to these variables depend on the section where the object is inserted.

The table is also subdivided into two main columns:

1. Name: In this column the names of the variables are visualised.

2. Value: In this column it is possible to display and modify the start values of the variables.

Creating a new variable To add a new object variable enter the following menu:

Press OK button to confirm or Cancel to stop the operation.

Setting a variable to a segment It is possible to associate the value of a "Real number" type variable to any segment of the polylines that make up an object. In this way, whenever the property value changes, the segment associated to it

will modify its features as well. To assign a property to a segment it is necessary:

1. To position on the line of the variable to be set to the segment.

2. To drag the variable towards the graphic window keeping the mouse left button pressed and indicate the segment to assign the variable to. As soon as the dragging starts the module activates the selection mode and marks with a yellow line the segment selected.

3. Drop the mouse left button when the segment to set the variable to has been selected ( marked by a yellow line).

The following menu will appear:

The variable value can be set to one of the segment characteristics, which are:

a. X offset variable: The value of the variable is set to the X offset of the segment from the previous vertex.

b. Y offset variable: The value of the variable is set to the Y offset of the segment from the previous vertex.

c. Slope variable (Y Offset/Slope): The value of the variable is set to the slope and the value of the X offset is calculated according to slope and Y offset .

d. Slope variable (X Offset/Slope): The value of the variable is set to the slope and the value of the Y offset is calculated according to slope and X offset .

e. Radius variable: The property value is associated to the radius of the segment arc.

Note: If in the menu there are more segments placed one over the other, all the segments will be indicated, so as to select the one desired.

Management of object properties

In this tab it is possible to create, modify and delete object properties, reference points,connection points and object groups.

The table of properties is very similar to the one you can find in typical section builder module and allows to display special points and properties on different levels so that they are easier to find and to use.

The object has a base level, coloured in dark grey, where its name and a set of sub-levels, coloured in

yellow to separate the different kinds of properties, are displayed. The sub-levels are the following:

11. Reference points: this level contains the object insertion point and all its reference points.

12. Property: this level contains all the object properties.

13. Draw: this level contains all the object drawing properties.

14. Connection points: this level contains all the object connection points.

15. Groups: for the object groups a set of levels are inserted, where the different names of the groups are displayed.

Objects tab is subdivided into three main columns:

Name: In this column the names of objects, reference points, properties and groups are

displayed. In case of insertion point, reference points and connection points, also a button is displayed, by which it is possible to set the point coordinates by selecting it from the graphic

window.

V: This column is active only for properties and it indicates whether their value can be modified during the insertion phase.

Value: In this column it is possible to display and modify the predefined values of object

properties.

Creation of a new property To make an object a parametric one, it is necessary to create some properties to associate to the

different polyline segments that constitute it. To add a property enter the following menu.

Menu Properties > Add > Property

be displayed in Name of table properties column.

In Data type group it is possible to set the property possible values, which are the following:

True/False: Property values are true/false logic conditions.

Integer number: Property values are numbers without decimals.

Real number: Property values are numbers with decimals.

Text: Property values are texts. If 'text' has been selected as type of data and the name of the property starts with "CODE" text, in the table of properties the list of section line codes will be displayed, while, if the name of the property starts with "FONT" text, in the table of properties will be automatically displayed the list of text styles.

Options list: Property values are an element of the list. To add an element to the list

write its name in the text field, under the item Options list and press Add button. To rename an element of the list, select the element from the list, change its value in the text field under the item Options list and press Rename button. To delete an element from the list, select the element from the list and press Delete button. To sort an element of the list it is sufficient to drag the name of the element to the position desired. The property in Tango code will assume 0 value for the first element, 1 for the second and so on for the other

elements in the list.

In Modify group it is possible to set:

Modes: Every property has got four different values, one for each situation where the object can be inserted. The modes available are the following: CUT-LEFT, CUT-RIGHT, FILL-LEFT, FILL-right. Mode field indicates how these four values of the property can change. The possible modes are the following:

Managing object polylines

An object is made up of one or more section polylines with a code ( Section elements ). These polylines

can be inserted directly from this tab or be imported from ProSt by the item


Command line: STYPE

In this table all the polylines are reported, that constitute the element with their vertexes. Besides, it is also possible to set the values of the offsets to X and Y of any vertex compared to the previous one, the

variables associated to these offsets and the arc radiuses.

Any polyline has a base level, coloured in dark grey, where its description is displayed, and a set of sub-

elements that are its vertexes. For each vertex the name is indicated, in Name column, the value of the offset to X in the column X Offset, the value of the offset to Y in the column Y Offset and, in case of arcs, the radius in Radius column.

The cell where the value of offsets and radiuses is displayed is subdivided into two rows, the upper one is referred to the kind of value that appears in the lower row.

The different typologies for X and Y offsets are the following:

1. Offset: The value of the lower line is the real value to be applied to X or Y offsets.

2. Slope: The value of the lower line refers to a slope, so the offset is calculated according to the value set and according to the other offset. For example, if in Offset X column we set the value of X offset as slope type, this will be calculated according to the value of the offset to Y and to the

slope value set.

3. Var. Offset: The value of the lower line is the name of a variable or of a property of the object and to X or Y offset the value will be applied, assumed by that variable or property.

4. Slope var: The value of the lower line is the name of a variable or of a property of the object and to the slope for the calculation of X or Y offset the value will be applied, assumed by that variable or property.

685

5. Coordinate: the value of X or Y coordinate is obtained by a connection point of the object.

6. Sum: The value of the X or Y offset will be calculated as the sum of the offsets of a set of consecutive segments of an object polyline.

Note: the polyline and the vertexes that contain the segments to sum must be drawn before the segment where the sum is used, that is they must be displayed in polylines table first.

The different typologies for radius are:

1) Value: The value of the lower line is the real value to be applied to the arc radius.

2) Variable: The value of the lower line is the name of a variable or of an object property, and to the arc radius will be applied the value assumed by that variable or property.

The first vertex of the polyline refers to the offset from the insertion point of the polyline itself.

Importing polylines from ProSt It is possible to draw a customized type object directly in ProSt graphic window of sections, using section polylines with a code, import it into the module Typical objects builder, make it parametric and then save it to use it in other sections and projects.

Tango code

It is possible to add some tango code to the object, so as to customize the values to associate to the

segments by formulas, selection of values and much more.

This tango code can be inserted in Tango code tab, on the right side of the module.

The code written in this section will be a part of the object code, it will be performed before the lines of the different objects are drawn and after all the properties, variables and reference points are initialised.

For all the properties and variables created, a set of local variables will be generated, to be used in this section and the name of these local variables will assume the name either of the property or of the variable defined, plus a prefix, according to the kind of variable data. The prefixes are the following:

b: for True / False type properties/variables

i: for Integer number type properties/variables

d: for Real number type properties/variables

s: for Text type properties/variables

For example, if we create a Real number type of property whose name is WALLHEIGHT, in tango code a local variable will be generated, whose name will be dwalhei, while, if we create a Text type variable whose name is WALLCODE, a local variable will be generated, whose name will be sWallcode.

To use a property / variable in this programming area it is possible to drag the property / variable line, keeping the mouse left button pressed; drop the mouse left button in the code area where the property / variable has to be inserted.

The correct name of the property / variable will be automatically inserted in the position indicated.

In case of reference points, a list will be displayed, with their own variables, where it will be possible to select the variable to be used.

Moreover, inside Tango code it is possible to define parts of the code to manage the variables modified on drawing the object, such as those associated to segments that must extend or those connected to reference points.

The different settings and checks performed on these variables must be enclosed by two instructions: {$BEGINBLOCK} and {$ENDBLOCK}.

For example, if a segment indicating a wall the variable dWallHeight has been associated and this wall extends as far as the ground, the value of dWallHeight variable will be recalculated automatically after

the extension.

If, for example, the foundation height is connected by a formula to the height of the wall itself, it is necessary to write this relation along with the previous instructions, so as to recalculate the foundation height correctly. The code lines will be for example:

{$BEGINBLOCK}

dWallFoundationHeight:=dWallHeight*0.35;

{$ENDBLOCK}

Tunnel

A tunnel, both in a topographic survey and in road design, is a specific situation, which cannot be dealt with and managed by traditional modes. ProSt possesses some commands and options which can meet this kind of need .

Calculate model

The survey of tunnels produces points which are located on the whole model, so it is necessary to consider not only the points on the upper side but also those on the lower side. In this situation it is not possible to obtain, by standard mehods, the 3D model of the tunnel. A specific calculation mode allows to obtain the 3D model by considering the approximate (plano-altimetric) alignment of the tunnel.

ProSt

Toolbar DTM:

Menu D.T.M. > Triangulation > Automatic

Command line: MAKEDTM


In Triangulation type select the option Tunnel; indicate the axis subproject identifying, both as

horizontal and as vertical alignment, the tunnel axis.

Barycenter height input field allows to define a height which is summed to the project profile to obtain elevations referred to the center of the tunnel.

To grant the correct execution of the command, it is therefore necessary to have identified, even approximately, the axis tunnel, both from a planimetric point of view (as axis elements) and as project profile (grade lines and curves); project elevations can either identify the tunnel vertical axis, and in this case the barycenter height can be null, or other elevations.

Calculation of section elevations

Extracting the tunnel existing shape as cross section presents the same problems illustrated above; also in this case, by considering an approximate alignment, the software can return the complete cross

sections.

In Origin selection list choose the item Survey band; then, set the width of the band to be considered as to the position of the section: all the topographic points which, compared to the position of the section in the planimetry, will be within the band, will be used to represent the transversal shape.

Then, select the option Survey points and then Tunnel. Press Next and complete the process.

To grant the correct execution of the command, it is therefore necessary to have identified, even approximately, the axis tunnel, both from a planimetric point of view (as axis elements) and as project profile (grade lines and curves).

Specific section dimensioning

In representing cross sections in tunnels it is often necessary to indicate the thickness (radial) differences between the existing model (terrain) and the project model; a specific section dimensioning allows to indicate the mode and the options by which to obtain this kind of dimensioning.

Repavement (Renew)

In road design it is often necessary not only to widen but to repavement or modify existing roads. In most cases, the problem is not only to apply a pavement layer above the existing one, but also to correct the vertical and horizontal alignment according to the policy regulations.

As far as the cover of the existing pavement, normally a minimum layer (overlay) of new material must be kept and this is precisely what ProSt Renew commands deal with. ProSt Renew commands can set a relationship between the project horizontal alignment, the edges of the existing horizontal alignment and the survey model of the current situation; from the analysis of such data, a profile polyline is calculated,

which will represent the ideal project elevation to keep the minimum layer required. The issue may seem a trivial one, but it is not so if we consider that modifying a horizontal alignment can change the position of the project axis compared to the existing one and, therefore, the determination of the project

elevation must take into account the shape of the existing terrain , of the new axis position as well as of the transversal slopes.

Data setting

A specific window allows to define the minimum overlay, also different according to the different points of the alignment, the edges of the existing pavement and the kind of project to use (simple, divided roadways).

Existing pavement limits: the limits of the existing pavement can be fixed distances from project axis or they can be defined by planimetry polylines with a specific code.

Therefore, specify the fixed width for right and left side, or the code of the planimetry polyline representing the limit of the existing pavement on the left and on the right.

length of the traffic divider and the position of the superelevation point.

Calculation of overlay polylines

Y module - Railway design and grinding Y module extends base module functions making it possible to carry out complete design, planimetry, profiles and sections, of single and double track railway lines. Some specific elaborations are also available, to allow check and grinding of existing railway lines according to survey.

The design of a railway axis is performed exactly in the same way as that of a road axis, so the commands used and the sequence of the steps to follow are more or less the same: there are, of course, some differences, so in railway design we do not speak about superelevation on curve in terms of slope,

but of superelevation of the external rail compared with the internal rail.

Some of the tool commands then change their function if the axis considered is a railway axis; an axis subproject becomes a railway axis subproject when in Planimetry properties a railway policy is set as the policy to be used.

The following commands present some differences if the axis subproject is a railway one:

Polycentric curves, consecutive curves in the same direction, with no intermediate horizontal straights, are numbered as if they were a single curve; therefore, if a polycentric curve starts for

example with curve number 5, the curves of the polycentric will be called 5/a, 5/b, 5/c,...; the following curve, after a horizontal straight, will be curve number 6. Such information will be

reported in axis elements reports, profile drawing, geometry annotation.

In Superelevation and widening window and in profile table the superelevation appears, not the transversal slope.

Geometry annotation produces a drawing in which the table reporting the curve data reports

also the superelevation and the data referred to the transition curves connecting the curve to the horizontal straights.

Profile drawing reports superelevation value.

It is possible to build and use typical sections for railway, equipped with rails, traverses, ballast, cable troughs, catenary masts and railway car. The section drawing appears complete with rail elevation.

As far as the check and grinding of existing railway lines, the following commands are available:

Generate track polylines: by this command it is possible to generate the planimetry polylines corresponding to the two rails of the track; the polylines generated can have also an elevation if a vertical design has been performed and superelevation and widening have been calculated. In case of a double track and a single project axis, the command can generate the four rails of the two tracks at the same time, no matter if the axis is situated either on one of the tracks or between the two tracks.

Check distances between rails: This command checks the distance between two rails along the whole axis or part of it. It is It is possible to set minimum and/or maximum speed; in this way the tool automatically highlights the stations where the limits set are not respected.

Curve staking: This elaboration returns for fixed points and intermediate points, at fixed step, the following information: station on axis, partial on axis and partial on chord between fixed points, distance and vertical distance from rails, vertical distance of fixed point from lower rail, camber,

superelevation, track gauge; moreover, it reports axis horizontal and vertical data as well as the speed on different stretches. The data calculated can be printed on a specific report.

Deviation survey-project: this elaboration returns the deviations of the new alignment from the survey data referred to the existing alignment; for each survey point the following information is reported: station on axis, planimetric position of survey point and of the corresponding point on project axis, height difference and distance of project compared with the existing situation. Calculated data can be printed on a specific report.

The following window will appear, which is subdivided into two pages, Settings and Start and end:

Settings page

It is possible to calculate the tracks both in a single track design and in a double track design.

Single track In this case the tool simply requires to indicate the codes to be assigned to planimetry polylines respectively for left rail and right rail.

ProSt

712

Double track

Axis position: the tool requires to indicate where project axis is situated compared with the two tracks. The axis can be in one of the following positions:

In the center between the two tracks

In the center of left track

In the center of right track

The tool will then prompt for the codes to assign to the four planimetry polylines which will be generated: the left and right rail of the left track and the left and right rail of the right track.

Double rail center space: the tool requires to indicate the value of the space between the two rails.

Use calculated widening: in both modes, single or double track, it is necessary to specify whether in

rail calculation it is necessary to take into account the widening calculated on curve.

Start and end page

This page allows to define the axis segment on which to perform rail calculation.

Complete: by this option rails are generated along the whole axis.

Partial: by this option the rails are generated only on part of the axis. It is possible to enter Start



Confirm before inserting: by activating this option the tool will draw the polyline calculated according to the settings given and will ask to confirm the insertion:

Do you confirm the insertion|Yes/No<Y>: by answering No the tool the tool will annul the drawing and will go back to the previous window to let the parameters be modified.

By pressing OK button the generation of the planimetry polylines representing the rails is activated.

Deviation survey-project

This elaboration returns the deviations of the new alignment from the survey data referred to the existing alignment; for each survey point the following information is reported: station on axis, planimetric

position of survey point and of the corresponding point on project axis, height difference and distance of project compared with the existing situation. Calculated data can be printed on a specific report.

Curve staking

This elaboration returns for fixed points and intermediate points, at fixed step, the following information:

station on axis, partial on axis and partial on chord between fixed points, distance and vertical distance from rails, vertical distance of fixed point from lower rail, camber, superelevation, track gauge; moreover, it reports axis horizontal and vertical data as well as the speed on different stretches. The data calculated can be printed on a specific report.

button.

Fixed points Survey subproject: select the survey subproject containing the fixed points between which to perform curve staking.

Use polyline between fixed points: by activating this option it is possible to choose a planimetry polyline to use as a reference between fixed points and on which to perform curve staking. If this option is not active the tool builds its own polyline joining together the fixed points once they have been ordered according to their station on reference axis.

Polyline between fixed points: select the polyline to use as reference between fixed points by

using button .

Settings Staking distance: Feed step along reference axis which determines the frequency measures are
