摘　　要：基于车流特性提出了一种新的站点通行能力计算方法,深入分析路内公交站点站内外公交车辆的运行特性,分两步建立了路内公交站点通行能力模型.首先根据站点内外的车辆运行特性建立路内站点物理设施通过能力的计算公式,然后采用生灭过程的分析方法,分析车辆进站出站的运行过程及生灭参数,建立路内站点公交车辆最大到达率及通行能力的模型公式.通过编程求解模型得到了不同泊位数、不同停靠时间的路内站点通行能力数值表,为站点的规划和建设提供了可参考的依据.最后通过南京鸡鸣寺站点的实例计算验证了该方法计算结果的合理性.Although the bus-flow volume in bus stops is lower than capacity of stop, congestion phenomenon occurred frequently, which affects the service lever of stop and bus line seriously. The paper put forward two concepts of bus stop capacity based on bus flow characters. Analyzing the bus running characters in-out on-line bus stop, it constructs the capacity model of on-line bus stop in two steps. First of all, construct the calculation formula of on-line bus stop physical facility capacity, and based on which, establish the bus arriving rate model of on-line bus stop adapting birth-death process method and solve out the capacity schedule based on bus flow characters in different berths, different dwell time, all of which provide a preference for the bus stop building and planning. Finally, a calculation example is performed to verify the method reasonable and applicable.
