以深圳市轨道交通为例,通过对深圳市地铁客流的分析,以及对A、B型车的建设成本与运营成本的比较,探讨城市轨道交通车辆选型的问题。最后得出结论:1)车辆选型应全线综合考虑,尽量选用建设及运营成本较经济的车型。针对局部区间运能不足的情况,应增强城市轨道交通线网布局,增强各运营线路的换乘节点数量,完善局部区域的城市综合交通体系,给市民的出行提供多种选择。2)车辆选型从节能方面应综合考虑整个运营期间的乘客满载率。3)因B型车车体的长度、宽度及线路曲线半经小于A型车,故从地铁站、区间、车辆段土建结构造价及工程拆迁成本,以及运营噪声和振动等方面考虑,如B型车能满足远期客流要求,选用B型车较A型车更能体现地铁绿色环保的价值。

[Abstract]
Vehicle type selection for Shenzhen urban rail transit was carried out through the comparison of construction costs and operation costs between vehicles type A and B. Conclusions were reached: 1, comprehensive considerations should be made to select vehicles with lower construction and operation costs; 2, from the perspective of energy-saving, the full-load percentages of passengers of vehicles during operation period should be taken into account; 3, since vehicle type B’s car body length and width as well as the minimum curve radius required are less than those of type A, from the aspect of civil engineering costs of station, line and depot as well as the operation noise and vibration, vehicle type B is preferred if it can embrace the long term passenger flow, while vehicle type B can meet the requirements of green environment better than vehicle type A.
