地铁高密度行车时救援组织优化

通过对广州地铁2号线历年发生的救援事件进行简要统计,得知故障源主要来自牵引控制系统,分析主要故障原因,以及救援组织中存在的主要问题,包括司机不熟悉车辆故障处理指南,调度发布救援命令不及时,现场信息沟通不畅等。结合地铁高密度行车阶段的特点,计算受到救援影响的列车数量并分析晚点情况。有针对性地提出救援组织优化方案,包括优化改造旁路开关;改造断电区;优化救援旅行速度,以减少列车增晚;优化救援路径,避免二次中断;优化救援组织流程,提高效率,尝试"裸车"动车等,并将优化措施应用于广州地铁6号线,取得很好的效果。

Optimizing rescue organization for a metro system with high-density operation

The historical data on metro rescue emergency were statistically analyzed, based on which the main reasons about rescues were identified, as well as the main problems including being unfamiliar with the guide, delayed release, unclear information, etc. Considering with the characteristics of the metro system with high-density operation, the trains and their corresponding delays due to rescue were calculated in detail. Based on the abovementioned, the corresponding optimization measures were proposed, including optimizing the running speed and route for the rescue vehicle, adjusting the rescue procedure, etc. These measures were applied to Line No.6 of Guangzhou Metro .
