城市轨道交通网络瓶颈现象的对策探讨——以上海市为例

An Argument of Planning Countermeasures against the Bottlenecks in Urban Mass Transit Network——take Shanghai as an example

以上海为例,分析了随着城市轨道交通网络的发展,由多线换乘产生客流不均衡的瓶颈现象,并探讨了纾解瓶颈的对策,指出轨道系统规划和线路设计必须事先在可能的瓶颈区段预留采取多种扩能措施的可行性,特别是在网格状的轨道系统规划中,除了满足一定的覆盖率指标外,可参考纽约经验,预留增加轨道数量的可行性。

There are many more bottlenecks n metro transportation,along with the developing of the urban mass transit network, because of the big flow of passengertransfer. Shanghai is such an example.This essay discusses how to dredge up the bottleneck,and points out that methods to expand transport capacity should be obligated in advance while a plan of urban mass transit network or a design of railway is processing. Furthermore,in the planning of a rail grid network,the capacity to add line amount might be considered besides some area density.The experience of New York City could be used for reference
