成都地铁首班车多点发车方案研究

Study on the Scheme of Chengdu Metro First Train Multi-point Departure

分析了较长地铁线路采用首班车单点发车方案时存在的问题。阐述了首班车多点发车方案的思路。提出空驶列车投入载客服务、提前安排线上存车及优化检修程序等3个可行措施。建立了全线服务时间、局部区段服务时间、空驶列车数和可用施工时间等4个评价指标。以成都地铁2号线为例,对首班车发车方案的效果进行分析评价,并计算了成都地铁全网采用首班车多点发车方案的服务时间。研究结果表明,将空驶列车作为首班车的首班车多点发车方案最优,可有效提早线路中间区段车站的首班车服务时间,延长线路服务时间,提高服务质量。

The problems existing in long metro lines adopting first train single-point departure scheme are analyzed.The idea of first train multi-point departure scheme is expounded.Three feasible measures including putting empty train into passenger service,arranging online train storage in advance,and optimizing maintenance procedures are proposed.Four evaluation indexes are established,including full line service time,local section service time,number of empty trains and available maintenance time.Taking Chengdu Metro Line 2 as an example,the performance of first train departure scheme is analyzed and evaluated,and the service time of Chengdu Metro adopting first train multi-point departure scheme for whole network is calculated.Research results show that using empty trains as first trains in the scheme of first train multi-point departure is optimal,effectively advancing the first train service time of line middle section stations,prolonging line service time,increasing service quality.
