地铁不同场段分布对其规模分配和运营成本的影响

城市轨道交通的车辆段和停车场需要占用大量的城市土地,合理分配场段规模可以优化占地面积,提高运营效率。基于一场一段情况下,总结出不同接轨方案的场段规模分配计算方法,提出场段分布位置在线路中接近对称时,场段规模大致相等的研究结论。同时,提出地铁收发车空跑距离计算模型,并对不同场段分布对运营成本的影响因素进行分析,提出降低运营期间场段收发车空跑运营成本的途径。

The Influence Caused by Different Metro Yard and Depot Arrangements on Its Size Distribution and Operation Cost

The rolling stock yards and depots of urban rail transit often occupy a lot of city land,so a reasonable distribution of the yards and depots can optimize the occupied area and improve operation efficiency.This paper proposed a calculation method of size distribution of yards and depots under different track junction schemes,and then drew a conclusion that: if the yards and depots were arranged symmetrically in the metro line,the scales of both the yard and depots would be roughly equal.Moreover,this paper proposed a calculation model of the empty running distances of car's dispatching and returning.After analyzing the influences of different yard and depot arrangements on the operation cost,this paper suggested some measures to reduce the operation cost of the empty running of car's dispatching and returning.
