摘要
为解决突发事件导致公交系统服务水平下降的问题,基于均衡公交车辆车头时距的调度思想,提出了能够适应于突发事件的快速动态滞站调度算法,建立了突发事件下的单线路公交动态调度模型。通过建立滞站调度的数理基础,分析了单站车头时距的控制问题,分析了快速滞站调度策略,从而得到了全线车辆的最优滞站调度算法,并对其进行数理分析和仿真验证。结果表明:该方法能均衡全线车辆运行时间间隔,降低乘客平均候车时间,有效提高公交系统运行服务水平。
To solve the problem of the service level decline of the public transport system in emergent events, a rapid algorithm of dynamic holding scheduling adapted to emergencies was put forward based on the scheduling idea of equilibrium headway. A single line bus dynamic scheduling model was established under the emergencies. A mathematical foundation of holding scheduling was established, the headway control strategy at one station was analyzed, and the rapid dynamic holding scheduling strategy was designed, so as to get the optimal algorithm of holding scheduling in the line. The feasibility of the proposed algorithm was proved through mathematical analysis and simulation verification. The results show that this method can be used to balance headways of running buses and reduce the average passenger waiting time so as to effectively improve the system operation service level.
