The document outlines the framework for urban transportation planning, detailing study area delineation, travel movement patterns, and various survey methodologies. It includes classifications and evaluations of traffic volume, methodologies for inventory and capacity studies, and the significance of traffic volume studies for highway planning and operational programs. Additionally, it discusses sampling techniques and sizes necessary for obtaining representative data in transportation studies.

Traffic Volume Study
Traffic volume is defined as the number of vehicles crossing a
section of road per unit time at any selected period.
Information gathered…..
 Hourly, daily, yearly and seasonal traffic volume variations
 Volume and direction of traffic
 Variation of vehicle flows on different parts of a road
system
 Proportion of two wheelers, cars, heavy vehicles, slow
vehicles etc. (Traffic Composition)

17. 17
 Average Annual Flow
 Average Annual Daily Traffic (AADT)
Total yearly volume divided by number of days in a
year (365)
 Average Daily Traffic (ADT)
Total volume during certain number of days divided
by number of days
 Hourly Volume (HV)

18. 18
Uses of traffic volume studies
 Annual Total Traffic Volume
 Measuring & establishing trends in traffic volume
 Annual travel in vehicle – km used for economic analysis
 Computation of accident rates
 Estimation of highway user revenues

19. 19
 AADT or ADT Volumes
 Highway planning activities: Development of express
ways ,Urban free ways, Bye – passes etc.
 Prioritisation of highway improvement programmes
 Measuring present demand for service
 Evaluating the present traffic flow with respect to
existing highway system

20. 20
 Peak Hourly Volumes
 Geometric design with respect to number and width of lanes,
intersection design etc.
 Determination of deficiency in capacity
 Justifying use of control devices such as signals, rotary, markings
etc.
 Developing operational programmes such as one way street,
designation of streets etc.
 Justifying other regulatory measures like parking, turning, stopping
etc.
 Highway classification
 Justifying enforcement and its planning
