Abstract

Performance of any signalized intersection is evaluated in terms of level of service which is based on vehicle delay. The delay relates the time lost by the vehicles while crossing intersections. As the vehicle arrivals are random in nature and it is difficult to estimate correctly, the delay can be determined by different models viz., deterministic queuing, steady-state stochastic and time-dependent stochastic models. The assumptions made in these models make the delay estimation simpler or at least to a reasonable level
of acceptance. The present research is involved with development of vehicle delays at selected isolated intersection in Hyderabad. Detailed field studies have been conducted at an isolated signalized intersection in Hyderabad by video-graphic technique. The vehicles arrival rate, times lost in waiting in front of the stop line and departure rate are obtained from these videos. The developed delays models can be used for prediction delays at any other such isolated signalized intersection, with the similar traffic conditions.
