Figure 2-4: Spot speed study

d. Delay speed study

 A travel time study determines the amount of time required to travel from one point to another
on a given route.
 Information may also collected on the location, duration, and causes of delays.
 Data also aid the traffic engineer in identifying problems at the location.
 Determine the efficiency of a route with respect to its ability to carry traffic
 Identification of locations with relatively high delay and the causes for those delay.
 Determine the traffic times on specific link for use in trip assignment models
 Performance of economic studied in the evaluation of traffic operation alternative that reduce
travel time.
 To evaluate the change in efficiency and level of service with time.
 A travel time study determines the amount of time required to travel from one point to another
on a given route.
 Information may also collected on the location, duration, and causes of delays.
 Data also aid the traffic engineer in identifying problems at the location.

e. Vehicle parking study

 The need of parking spaces is usually very great in the areas where land uses including
business, residential and commercial activities
 Providing adequate parking space to meet the demand for parking in central parking district
may affect the level of service.
 To get the valid information (before and latest)
 To know whether it is adequate parking or not
 To provide information needed to enable the implementation of payment by the parties
involved.

2.2.3 The general criteria of transport plan selection

 Social aspect
 Community association
 Services and facilities provided
 Occupant transfer
