摘要: 基于长沙地铁2号线一期工程实际设计和运营情况分析,受限于轨旁信号设备,西延线开通后行车密度加大,列车进出车辆段的运行效率将受到较大影响。提出一种通过分别缩短正线和车辆段内列车的运行间隔以达到提升所有运行模式列车出入段效率的方案,并在实际运营过程中得到验证,为类似工程问题提供一种参考解决方案。

Abstract: According to the analysis of the actual design and operation of the first phase of Changsha Metro Line 2 project, the efficiency of trains entering and exiting the depot will be affected a lot due to the limitation of trackside signaling equipment, with the increase of traffic density after the opening of west extension line. Therefore, this paper proposes a scheme to improve the efficiency of the train entering and exiting depots of all operating modes by shortening the running intervals of the trains in the main line and the depot, has been verified in the actual operation and provides a reference solution for similar engineering problems.

Key words: signaling system, capacity of entering or exiting depot, transfer track, overlap section, route
