travel delay, travel costs are expensive (the price of vehicles, parts, fuel, tolls, etc..), As well

as the growing danger of travel and uncomfortable.

TRANSPORTATION PLANNING OBJECTIVES ARE:

Efficiency - To ensure that the trip could dibuatdengan to be the fastest and cheapest. This

can be achieved by ensuring a low cost for the provision, operation, and maintenance of

transportation facilities.

Conservation of resources - Supply of resources used in the preparation, operation,

maintenance, and use of transportation facilities is terhad.Sumber these sources is the time,

energy, human resources, materials and land.

Financial Conservation - To reduce peruntukankewangan be requested from the

authorities untukpenyediaan, operations and maintenance kemudahanpengangkutan.

Taking care of the environment - To reduce the impact of transport and utilization

darikemudahan on Environmental.

Improve safety - To reduce kehilangannyawa, injuries and property damage

disebabkankemalangan to the driver, passengers and pedestrians.

As part of the land use planning, development of the area can be implemented quickly

IMPORTANCE OF TRANSPORTATION PLANNING

A. To make a detailed study to ensure & verify the form of a travel-related problems.

B. Outlines the procedures to carry out a more systematic study as well as its ability to base &

format for coordination so that the aims & objectives are achieved.

C. Can produce an integrated transport system with the use of land & institutions to achieve good

policy towards improving the quality of city travel.

THE PLAN (LEVEL GOVERNMENT / STATE)

a) Planning the short term (


3/5

i. Interviews on the street

- Sample of siege vehicles that crossed the line asked to stop and the driver will be interviewed by

the observer data to get some needed information.

- The advantages of this method is the necessary evidence is obtained directly and fairly accurately.

- The main disadvantage of this method is the only evidence obtained in vehicle only.

ii. Using postcards

- The method of using postcards may be a relatively cheap alternative compared to the interviews on

the street to get the data off the course.

- In general, there are two types of methods used postcards, which are:

I. The first method

- It is a way to do research on certain points, and the drivers of vehicles stopped and asked to begiven a prepaid postcard. Motorists are required to fill this postcard and post it back time after

completed.

II. The second method

- By way of sending a postcard by mail to vehicle owners.

iii. Vehicle registration number

- The registration number of vehicles crossing the selected stations recorded by observers. Usually,

three or four of the last registration number was recorded.

- The advantages are, do not interfere with traffic flow as vehicles are not required to stop.

- The drawback is that it is difficult to do analysis for all data that are observed at other stations must

be collected in advance before. Because all stations should be observed simultaneously by this

method requires a large number of observers.

iv. Interview at home

- The main method for obtaining travel data is to do the interview at home.

- The advantages of this method is that all evidence about the trip every householder be obtained

directly.

- The negative side is that takes time and the high cost and need of a butterfly interviewer

v. Questionnaires

- As an alternative to the method in the home interviews, questionnaires available can also be

distributed to a sample of households was selected.

- The advantages of this method is not costly.

(B) The volume

- Conducted to obtain accurate information on the number and movement of vehicles (also

pedestrian) on or through an area, or at selected points in a study area.

- Divided into two methods:

I. The method is manual / Manual

- It is recorded manually by vehicle type. Meanwhile, the period depends on the intended use of

data in the study and filled in a special form.

- The advantage that, simple and cheap and the data were analyzed and the data collected easily in

abnormal conditions can be obtained.

- The drawback is the, need more staff if the flow is congested or more junctions and the data were

not accurate due to the negligence of observers.

II. Method of Mechanical / Automatic

- The vehicle crossed the study area will be detected by special sensors which is used when the

traffic flow data needed for the long run.

- The type of detector are:

Detection Equipment Mechanic

Contact Electrical Equipment

Magnetic Detectors

Video Recorder and Photoelectric

(C) Review the local speed

Made to measure vehicle speed of a sample of individuals who pass a given point on the road or

the road.

Speed is the basic measure of traffic performance and has many uses.

(D) travel speed and delay studies

Performed as an indicator of the level of services provided, and the effectiveness and efficiency of

the flow of a street.

The service times are defined as total elapsed travel time (including stops and delays) who had

traveled by the vehicle while moving from one point to another point on a route specified in the

existing traffic conditions.

(E) Review of parking

Done to get some needed evidence that an assessment ofthe parking problem can be carried out.

The purpose of the parking study include:

- Identify parking needs.

- Determine the physical requirements to supply the place of the existing parking can be modified or

added.
