APPENDIX 5B VERTICAL HIGHWAY ALIGNMENT SIGHT DISTANCE CHARTS

INTRODUCTION The following charts are to be used as a guide in the design of vertical highway alignments for new construction, reconstruction, Freeway 2R, and Freeway 3R projects. For all Non-Freeway 2R, Non-Freeway 3R, and for minor commercial and residential driveways, the various sections refer the designer to HDM Chapter 7 for guidance. Minimum values of curve lengths are calculated. Longer curves may be used where feasible and appropriate. The equations and tables are based on the AASHTO’s “A Policy on Geometric Design of Highways and Streets,” 2011.

5B-1 1/15/15


Computations are based on the following formulae:

S.S.D. < L.V.C.

S.S.D. > L.V.C.

Based on height of eye = 3.5 ft and height of object = 2.0 ft

L = Length of Vertical Curve (L.V.C.), ft

S = Stopping Sight Distance (S.S.D.), ft

A = Algebraic Difference in Grade, %

Note: 1. The minimum length of crest vertical curves should be the greater of:a. 3 times the design speed.b. The length needed to provide minimum stopping sight distance.

Example: Difference in Grade = 5%, Actual Design Speed 60 mph1. Subtract 20 mph from Actual Design speed. The recommended design speed equals 40 mph.2. Use the following table to determine the crest vertical curve length.3. The length of the crest vertical curve equals 179 ft.

2. For all Non-Freeway 2R, Non-Freeway 3R, and minor commercial and residentialdriveways, refer to HDM Chapter 7, Exhibit 7-7 Minimum Stopping Sight Distance (SSD) for the minimum vertical stopping sight distance. The recommended design speed is Actual Design Speed minus 20 mph.

Guidance: A Non-Freeway 2R or 3R project with an actual design speed of 60 mph will have a recommended design speed of 40 mph (Subtract 20 mph from actual design speed of 60 mph).

Computations are based on the following formula:

S.S.D. > L.V.C.

S.S.D. < L.V.C.

L = Length of Vertical Curve, ft C = Vertical Clearance = 14 ft

S = Sight Distance, ft h1 = Height of Eye = 3.5 ft

A = Algebraic Difference in Grade, % h2 = Height of Object = 2.0 ft
