城市轨道交通车站站台客流集散模型与仿真

Modeling and Simulation of Passenger Flow Distribution on Urban Rail Transit Station Platform

结合车站站台客流类型、客流集散流程和客流集散影响因素,建立城市轨道交通车站站台客流集散模型。采用Anylogic软件建立站台客流集散仿真流程和仿真模型。以北京地铁4号线北京南站站为工程背景,对其站台客流进行了仿真计算。结果表明,站台客流集散模型能有效刻画高峰时段内站台客流的集散变化规律,验证了仿真模型的可行性。进一步探讨了高峰时段内基于不同发车间隔和不同上下行时间差的站台客流集散变化规律以及疏散仿真试验。形成了一种可操作的站台客流集散动态分析方法,可为城市轨道交通运力配置和车站客流组织提供一定参考。

Based on the types,distribution process and influencing factors of passenger flow distribution on urban rail transit station platform,a platform simulation model is built to simulate the passenger flow distribution process by using Any logic software.Taking the platform of the South Station on Beijing metro Line 4 as the engineering background,the feasibility of the model is verified by the functional description of the dynamic variation regularities of passenger flow distribution during rush hours.Then,the dynamic variation regularity with different train headway and time lags during rush hours is further studied,and the evacuation simulation is explored to form an operable dynamic analysis method for passenger flow distribution on station platform and provide a certain reference for train capacity allocation and station passenger flow organization.
