摘 要:为了提升高峰期地铁站厅乘客服务水平,缓解站厅客流拥挤情况,针对传统站厅设施布局评价指标体系中缺乏行人运动与时空的相关性的问题,应用Anylogic行人库对高峰期地铁设施合理布局设计进行仿真研究,并提出三个新指标:人流交织区域及人流冲突点、局部拥挤指数和设施利用不均系数。以广州大学城北站作为对象调研客流数据,确定仿真模型输入参数,建立站厅设施布设仿真模型,仿真后得到人流冲突点图、站厅拥挤密度图和设施饱和度图,探究大学城北站站厅现有设施布局的不合理之处并提出优化方案,再次进行仿真,仿真结果表明改进后的方案能有效改善行人流线、路径选择以及设施利用水平,仿真模型考虑了高峰期客流的时空特点以及对站厅设施布局设计的影响,对实践有较好的指导性。In order to improve the passenger service level and alleviate the congestion of the metro station hall, aiming at the lack of pedestrian movement with time and space in the traditional facilities layout evaluation system, a simulation study about the reasonable design of metro facilities during peak hours was carried out based on Anylogic pedestrian model, and three new indicators were put forward: pedestrian intertwined areas and conflict points, partial congestion index, and facility utilization inequality. Based on the data of passenger flow of Higher Education Mega Center North Station, a simulation model and some input parameters were established. After the simulation experiment, the diagram of crowded point, the map of crowded density and the facility saturation were obtained, which can be used to explore the irrationality of the existing facilities in the station and to propose an optimization scheme. After simulating again, its result shows that tile improved scheme can effectively improve the pedestrian flow line, route selection and facility utilization level, indicating that the simulation model which takes into account the temporal and spatial characteristics of peak passenger flow as well as the impact of station hall facilities layout, can give better guidance to the practices.
