利用正线夜间停放客车提高运营效率的可行性

如果一条线路只有一座车辆段，并设在靠近线路的端部时，必须使线路两端终点站的运营服务时间基本接近。非运营时间客车全部停放在车辆段的传统做法，使运营时间利用率低、运营与夜间维修和施工时间的矛盾日渐突出。通过对利用正线非运营时间停放过夜客车来提高运营效率的可行性研究，结合广州地铁1、2号线的现状分析，提出解决方案，可减少列车空走和司机劳动强度，提高服务水平，有效地提高正线运营效率。

Feasibility Study on Improving Operational Efficiency by Placing Passenger Trains on Metro Lines at Night

If there is only one depot at the end of a metro line,service time of one terminal station will basically not be the same as that of the other terminal station.Traditionally,all trains are placed in depot in non-operating hours.This cannot solve the increasingly prominent contradiction between operation hours and maintenance together with construction hours.Through analyzing the status of Guangzhou metro Line1and Line 2,this paper proposes a solution for improving operational efficiency by placing passenger trains on metro lines at night,which helps to increase operational time at night and to reduce unnecessary vacant running trains and operational cost.
