北京地铁西直门站换乘流线优化方案探究

北京地铁西直门站是大型换乘站,采用单向换乘模式。根据西直门站的周边条件,从客流量、站内设施布局和标志设置入手,通过分析4号线建成后西直门站换乘流线及换乘客流的现状,指出了西直门站乘客换乘方式存在的主要问题。提出了优化换乘流线(方案1)及工程改造(方案2)两个优化方案,并对方案2的换乘客流进行了仿真及评价。方案2解决了西直门站3线换乘问题,提高了西直门站的换乘效率。

On the Optimum Schemes of Transfer Lines at Xizhimen Station of Beijing Metro

Xizhimen Station of Beijing Metro is a major transfer hub and uses one-way transfer mode.According to the surrounding conditions,the passenger flow,the layout of station facilities and the identity settings of the station,the status of the transfer streamline and the transfer passenger flow at Xizhimen Station after the completion of Metro Line 4 are analyzed,some main problems existing in the passenger transfer mode are exposed.Then the Optimal Transfer Streamline(Scheme 1) and the Engineering Reconstruction(Scheme 2) are proposed,a simulation and evaluation of the transfer passenger flow in Scheme 2 is made.The result shows that Scheme 2 could solve the transfer problem between three metro lines at Xizhimen Station and improve the transfer efficiency at the same time.
