公共交通大站快车调度模型

为满足公交企业调度管理需求,建立公交管理中实施快车调度的数学模型,应用公交随车调查数据,进行客运量O-D矩阵反推,筛选出公交客流量O-D矩阵中较大的站点,作为大站快车站点,并将原线路客流量分为快车站点和调度后线路客流O-D矩阵,分别用断面客流量和车厢满载率进行发车时间表设计,最后采用速度、等车延误、行驶延误、停车次数等指标对调度前后模型进行评价.编制的计算机程序,实现对客运量O-D反推、断面流量和公交车时间表程序化计算.结果表明:模型可以减少乘客延误和车辆停车次数,满足了不同乘客乘距的出行需求,提高了车辆旅行速度和服务质量.

Express bus scheduling model and application

An express bus scheduling model in transit management is proposed,adapted to the demand of transit scheduling management.Appling the survey on vehicle data,the express bus stops were determined according to the inverse deduction of passengers flow O-D matrix,and the bigger unit of the O-D matrix was filtered.The original route passengers flow O-D matrix and the scheduled route passengers flow O-D matrix were determined applying the maximum section of passenger flow.Then,the departure interval of the original route and scheduled route were scheduled separately.Finally,the effect of the express bus scheduling model was evaluated using the indexes including traveling speed,wait time delay,ride time delay,layover times,etc.The is paper programs the procedure which can compute the inverse deduction of passenger flow O-D matrix,section of passenger flow and departure interval.The conclusion indicates the express model can decrease the passenger delay and stops times,meet the different travel demands of average distance carried and the improve the traveling speed and the level of service.
