基于客流模拟的地铁车站建筑公共区方案研究

Research on Building Public Area Scheme of Subway Station Based on Passenger Flow Simulation

运用排队论多服务台有限队列模型和Legion软件,结合铲湾中站换乘站,对平行扶梯倒八字方案、错台扶梯平行方案、平行扶梯八字方案3个建筑公共区方案进行客流模拟。经过对3个方案的热力图分析,可以得出:方案三客流设施服务强度弱,出现拥堵点;方案二客流设施服务强度一般,出现局部拥堵;方案一客流设施服务强度高,虽出现人员密集但整体流畅。方案一由于设备数量充足,设备之间距离合适,客流服务功能好,为本项目最优方案。

This paper uses the multi-service desk finite queue model of queuing theory and Legion software to simulate the passenger flow of three building public area schemes of the transfer station of Chanwan Middle Station:parallel escalator inverted splay scheme,staggered escalator parallel scheme and parallel escalator splay scheme.Through the thermal diagram analysis of the three schemes,the following conclusions can be made:for Scheme 3,the service intensity of passenger flow facilities is insufficient,resulting in congestion points.For Scheme 2,the service intensity of passenger flow facilities is moderate with local congestion.For Scheme 1,the service intensity of passenger flow facilities is high enough that the overall flow is smooth,even though there are dense personnel.Scheme 1 is the best scheme for the project because of the sufficient equipment,the appropriate distance between equipment and good passenger flow service function.
