摘　　要：通过分析在公交站点附近各种车流的运行特征,归纳总结了影响社会车流延误的主要因素,利用排队论、交通流理论以及BPR函数建立了社会车流延误的模型,并以蓟门桥西站为案例,研究了不同参数变化对社会车辆延误的影响.研究结果表明:社会车辆总延误和单位车辆延误随流量的增加呈指数上升趋势,当流量达到7 232 pcu/h时,排队系统趋于不稳定;而总延误随公交到达频率和平均进站速度的提高而下降.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 7232 pcu / h;however,the total delay of vehicles decreases with the increases of the arrival frequency and the average pull-in speed of buses.
