城市轨道交通列车救援方案选择与应用实践

Train Rescue Plan Selection Discussion and Application Practice in Urban Rail Transit

【目的】在高峰时段行车间隔不断缩小的情况下,城市轨道交通一旦发生故障,且在一定时间内无法完成故障处置并动车,故障车后续列车将严重拥堵,故障列车与前车之间会产生较大运行间隔,因此如何快速、安全地采用救援组织方法将故障列车撤离正线尤为重要。【方法】选取后方列车为救援车,以正线就近存车线及车厂(终点站折返线)作为退出服务位置,建立救援方案集;结合事故事件定责情况,以最大晚点时间及连续中断时间最短为优化目标,建立救援路径选择模型。【结果】通过实例进行验证,确定线路不同位置发生故障时最优的救援路径。【结论】救援方案集、救援路径选择模型可应用于不同线路,为调度员组织救援及调整行车提供支撑,保障列车运行秩序,减小对运营服务的影响。

[Purposes]In the case of shrinking traffic intervals during the peak time,once the urban rail transit train breaks down,the train would be unable to complete fault handling and run within a certain pe⁃riod of time,which will result a serious congestion and a large headway between faulty train and front train.So it is important to remove the faulty train from the main line by adopting better rescue organization method.[Methods]This paper selects the rear facing train regard as the rescue train in this text and the nearest storage line and depot(terminal turn-back line)as the exit service location to establish a rescue plan set;based on the determination of responsibility for accidents and events,this paper a rescue path se⁃lection model.[Findings]The optimal rescue path when faults occur at different locations is determined by validating through instances.[Conclusions]Rescue plan sets and path selection model could apply to different lines to provide support for dispatcher rescue organization and train operation adjustment,en⁃sure the order of train operation,and reduce the impact of operational services.
