智能公共交通系统动态调度模型研究

Dynamic scheduling model for intelligent transportation system

分析了影响车辆正常行驶的主要因素以及恢复车辆运营的调度方法,建立了一种动态调度的模型.模型的思路是将延误到达的车辆在线路始发站不停车发出,中途站点载客,目的是减少车辆停车时间,恢复线路车辆的正常车头时距,避免车厢内由于大间隔造成的拥挤现象.利用哈尔滨市公交92线数据进行模型检验,采用高峰时间段车辆延误数据,分别对1辆车和2辆车延误进行调度调整,结果表明,该调度方法有效地减少了乘客等车时间,为车辆间距控制系统提供了有效的模型.

The main factors affecting normal driving and an ordinary bus scheduling method after adjustment are analyzed so as to construct a dynamic scheduling model. In this model, delay buses departure at the beginning station without stopping and passengers get on at the midway stations, which helps to decrease the bus stopping time, recover the normal headway and eliminate the compartment congestion induced by large interval. With statistical delay data in rush hour of No. 92 Bus in Harbin,the driving delay of one bus and two buses is adjusted, which proves that the proposed method can diminish the waiting time effectively and provide a useful auxiliary tool for the control system of bus interval.
