In order to study bus priority control based on downstream bus stops at intersections, bus priority application is established which considers whether bus queue at downstream stop is “overflow” and predicted arrival time is “early.” Improving on Webster’s method, the green time ratio is determined by passenger proportion and bus signal priority model is proposed with the objective of minimizing average passenger delay. Using an intersection in Xi’an, China, and its downstream bus stop as an example, signal cycle optimization and two priority control strategies for green advance and extension are compared and analyzed. The results show that the proposed signal priority model and the two strategies can reduce average passenger delay and average vehicle delay of target intersection, as well as shortening the deviation from bus schedule.
