上海轨道交通2号线龙阳路停车场CBTC改造后的运营能力分析

为解决上海轨道交通2号线列车高峰期满载及超负荷运行问题,需要在龙阳路停车场将列车插入正线投入运行。目前龙阳路停车场并未采用CBTC(基于通信的列车控制)模式,存在着插车效率低、出库间隔长等缺点,不能满足运营的需求。基于既有的土建条件、车辆参数和轨旁布置,结合卡斯柯信号系统,仿真分析了龙阳路停车场在CBTC改造后的运营能力。分析结果表明,改造后龙阳路停车场出入场线及插入正线的运营能力显著提高。

Operational Capacity Analysis of Longyanglu Depot on Shanghai Rail Transit Line 2 after CBTC Retrofit

In order to solve the problem of full loading and overloaded operation of Shanghai Metro Line 2 during the peak period,trains need to be inserted from Longyanglu Depot into the main line.But the depot has not adopted communication based train control(CBTC)mode and can not meet the operational requirements due to the disadvantages of low insertion efficiency and big outbound headway.Based on the existing engineering conditions,vehicle parameters,and track side layout,and combined with CASCO signal system,the operational capacity of Longyanglu Depot after CBTC retrofit is simulated.The analysis result shows that the operational capability of the depot is significantly improved in terms of the entrance/exit lines and the mainline insertion.
