Evaluation of Transit Signal Priority for Bus Rapid Transit in Heterogeneous Traffic Flow

Inefficient traffic signal control at intersections causes vehicle delays, increased fuel consumption, and vehicle emissions. With respect to the large number of fixed signalized intersections along the 7th line of Tehran BRT, passengers experience long delays and travel time while BRT is defined as...
