公交枢纽内多线路车辆实时调度优化方法研究

公交枢纽内多线路车辆的实时调度能够提高换乘效率,特别对于已经进行了发车优化的公交线路而某些车辆到达出现延误的情况。根据线路的延迟到达时间和换乘客流量等因素建立了公交枢纽内多线路车辆的实时调度优化问题模型,提出了基于整个系统费用最小的优化目标函数,并运用随机扰动梯度近似算法对问题进行求解。最后结合算例分析了本文方法的应用。

Study on Real-time Departure Control in Public Transit Hub with Multiple Bus Line

Real-time departure control in public transit hub with mutiple bus line can improve passenger transfer efficiency in a coordinated transit network,especially when some connecting routes are behind schedules at transfer stations.The model developed here is uesd to optimize the holding time for each available vehicle based on arrival delay of late vehicle and other factors such as transfer volume.Total system cost function are formulated and SPSA arithmetic is used to get the solution.Finally,the application example of this method is given.
