摘　　要：根据路段上公交车运行的实际情况,分析了公交车辆行驶及停靠对车流的影响。流量较小的情况下,将公交车看作服务台,利用排队理论、间隙理论建立了公交车影响产生的延误模型;流量较大的情况下,结合车辆到达与服务图示,建立了延误模型,最后给出了计算实例。为评价路段服务水平、确定更合理的路阻函数提供了理论支持。The impacts of bus running and stopping on the traffic flow were analyzed considering the real operation state of buses at the road segment.On the case of light traffic,treating the bus as a moving service station,a delay model by buses was established based on the queuing theory and the theory of gap acceptance.On the case of heavy traffic,a delay model by buses was established based on the arrival and service representation of vehicles.A solution example was demonstrated.The obtained results provide a the...
