长沙地铁万家丽广场站厅仿真及客流优化研究

城市轨道交通作为居民主要出行方式，为建设更舒适的出行环境，提高乘客在站厅的进出效率，减少乘客拥堵现象。本文以长沙地铁万家丽为原型，研究已经开通运营的换乘车站，在建筑面积固定的情况下，如何根据既有设备布局高效组织激增的进出站和换乘客流。基于万家丽近期和远期客流数据，同时重现排布验票闸机、楼梯的进出方向和位置，利用仿真软件充分验证方法的可行性和有效性。结果显示，新的排布方式可满足实际性需求，使客流组织方案与站内空间布局更加协调，一定程度上消除了乘客拥堵现象。基于仿真结果和理论计算结果对比发现，行人走行时间增加量随进站客流量的增加呈现先增后减再增的趋势，该趋势可为未来车站行人走行时间预估提供一定的理论基础。

Station Operation Simulation and Passenger Flow Optimization at Wanjiali Square of Changsha Metro

Urban rail transit is an important travel mode for residents. This paper focuses on the passenger flow organization at Wanjiali of Changsha Metro. The study investigates the strategies that efficiently organize the surge of in and out of the station and optimize passenger flow with existing equipment layout and under fixed building area. The goal is to provide a more comfortable travel environment, improve the entrance and exit efficiency, and reduce passenger congestions at the station. Based on the short-term and long-term passenger flow data of Wanjiali Station, this study proposes to re-arrange the entrance and exit directions and locations of ticket checking gates and stairs, and verifies the effectiveness of the proposed method using simulation software. The results show that the new arrangement can meet the practical needs and make the passenger flow organization scheme more coordinated with the station spatial layout. To a certain extent, it eliminates passenger congestions. From a comparison between the simulation results and the theoretical calculation results, it is found that the increase of pedestrian walking time increases first, then decreases and then increases again with the increase of the number of passengers in the station, which provides a theoretical basis for the prediction of pedestrian walking time in metro station.
