摘　　要：针对公交站点排队溢出导致的路段运行效率下降问题,通过分析混行交通条件下公交跳站运行对路段通行能力及乘客出行时间的影响,分别建立了小汽车和公交乘客的出行时间计算模型,并在此基础上建立了以乘客总出行时间最小为目标的公交站点停靠车辆数优化模型;以杭州市天目山路为例,使用上述方法对其站点停靠车辆数进行了优化,结果显示,优化后的停靠方案能够使小汽车运行速度提高9.32%,公交乘客的出行时间缩短3.98%,所有出行者的总出行时间减少4.75%;本文提出方法的优化结果能够为混行交通条件下公交跳站运行方案的设计提供基础。Aiming at the efficiency reduction problem resulting from overloading of bus stops, the travel capacity and traffic time of passengers impacted by limited-stop operation are analyzed under mixed traffic condition. On this basis, the methods for computing passengers＇ travel time by bus and ear are developed, respectively. The model of optimizing the number of buses stopping at stops with limited-stop operation is developed with the objective of minimizing the total travel time of the entire passengers. For this research, the Tian-mu-shan Road of Hangzhou city is used as an example. An optimal scenario is obtained with this model. The result showed that the travel speed of car after optimization increases by 9.32%, bus passengers＇ travel time decreases by 3.98%. The passengers＇ total travel time with limited-stop operation decreases by 4.75% the results of the proposed model can provide a basis traffic conditions. shorter than that with original all-stop operation. In addition, for the design of limited-stop operation scenarios under mixed
