Abstract

The implementation of the priority system for transit at signalized intersections with high traffic volumes will help reduce transit delays and red lights stop at these intersections. In this paper, we propose an unconditional active signal priority control method for the public transportation system, which includes regular buses and a Bus Rapid Transit. we examined 11 different modes of bus availability at the intersection, based on the estimated time of transit arrival. Reduce transit delays at the intersection, increase the convenience and reliability of public transportation, increase the total intersection efficiency and reduce the negative impact on personal vehicles are also considered. Finally, a simulation model was conducted by VISSIM by writing an algorithm modeling in VisVAP for the Keshavarzi-Daneshgah corridor with BRT and regular bus in Isfahan City, Iran. the results showed that, due to the implementation of this method, BRT passengers' delay decreased by an average of 65% and decrease regular bus passengers' delay by an average of 7% compared to existing signal control scenarios.
