Abstract: In order to reduce the bus delays in a bus stop, which located near signalized intersection, the bus stops are classified into two categories according to their locations on the road. A bus delay model is established based on the shockwave theory by analysis of the interaction influence between bus stop and traffic flow. If the bus stop is located upstream the intersection, bus delays include three cases and the expected delay values are obtained by probabilities and corresponding delay case. If the bus stop is located downstream the intersection, the coordinate system is established to describe travelling track of both buses and cars, and the bus delay model is constructed. Simulation was carried out with aid of Matlab. Simulation results show that, with the growth of traffic flow, signal cycle and dwell time, the bus delay increases if the bus stop is located upstream the intersection. If the bust stop resides downstream the intersection, the bus delay decreases first and then increases as it approach the upstream stop.
