城市轨道交通高峰时段站外限流措施的方案设计

The Scheme Design of Outstation Flow Restriction Measures in Urban Rail Transit During Rush Hour

针对城市轨道交通车站因大客流带来的安全隐患问题,提出了一种解决方法。通过设置站外限流栏杆,以减轻大客流带来的压力,同时对限流栏杆带来的便利性进行平衡。以上海泗泾地铁站为例,通过AnyLogic模型仿真,优化站外限流栏杆,研究不同设置对行人的影响。研究显示,限流栏入口开口越小、限流栏杆净距及拐角处宽度越大,行人平均进站时间减少,S型限流栏在三种中效果最佳。研究成果可指导优化限流栏杆布置、规划方案,提升城市轨道交通站应对大客流的能力。

Aiming at the safety hidden problem caused by large passenger flow in urban rail transit station,a solution is put forward.By setting the railings outside the station,the pressure brought by the large passenger flow is reduced,and the convenience brought by the flow limiting railings is balanced.Taking Sijing Subway Station in Shanghai as an example,AnyLogic model simulation is used to optimize the external flow limiting railings of the station and study the impact of different settings on pedestrians.The research shows that the smaller the entrance opening of the flow limiting barrier,the larger the net distance of the flow limiting barrier and the width of the corner,the average time of pedestrian entering the station decreases,and the S-type flow limiting barrier has the best effect among the three kinds.The research results can guide the optimization of flow limiting railing layout and planning scheme,and improve the ability of urban rail transit station to cope with large passenger flow.
