中文摘要：
在考虑客流需求波动及车辆运行时间随机变动的情况下,建立了以乘客候车期望和公交车辆利用率总体最优为目标的公交线路服务频率优化模型.利用蒙特卡罗方法随机模拟一条高频线路的公交服务,计算得到了给定线路参数下的最优服务频率.算例表明该模型可用来确定高频服务公交线路的发车时间间隔.
英文摘要：
It is a critical problem for balancing supply and demand of transit service to determine the service frequency of a bus route according to the passenger demands and operation conditions.Considering passenger demand fluctuation and stochastic variation of vehicle running time,an optimal model for determining bus route service frequency was developed.In this model,the expectation of passengers waiting for buses and the efficiency of running vehicles were aimed to achieve combined optimization.Monte-Carlo method was used to simulate high frequency bus route service and the optimal service frequency of this example route was calculated given the route parameters.The result shows that this model can be used to determine the bus departure interval of a bus route with high frequency service.
