Abstract: This study summarizes the main factors of slowing down flows of vehicles through analyzing the running characteristics of vehicles at bus stops, and developes the vehicle delay model by using the queuing theory, traffic flow theory and the BRP function. The West Jimen Bridge is selected as a study case to analyze the impact of the changes of the model’s parameters on the delay of social vehicles. The research results show that the total delay of social vehicles and the delay of unit social vehicle increase exponentially with the increase of traffic flow. The queuing system begins to be unstable when the speed of traffic flow reaches 7 232 pcu / h; however, the total delay of vehicles decreases with the increases of the arrival frequency and the average pull-in speed of buses.

Key words: urban traffic, bus stop, delay, queuing theory, traffic flow theory, BPR function
