地铁换乘站设施布局优化仿真研究

Simulation of Layout Optimization of Metro Transfer Station

在地铁换乘站设施布局中,由于乘客行走特征各异、流线复杂、各项设施间联动性强等特点,导致对换乘站的设施布局进行整体优化比较困难。本文利用Anylogic仿真软件进行建模,在输入车站具体参数后,仿真得出乘客平均排队长度、平均逗留时间、区域密度三项动态评价指标和行人密度图,以具体数据和图形的形式描述乘客流畅性、时效性和舒适性。通过模拟车站的实际运行情况,提出具体的设施布局优化措施,并以天府广场站为例进行了验证,结果表明,该仿真方法可以为地铁站设施布局和流线组织提供更好参考。

In a metro transfer station planning, it is very difficult to optimize the layout as a whole due to the different transit features of passengers and the consistency between passengers and station layouts. In this research, Anylogic has been used to model and simulate the passengers＇ average queuing length, average waiting time, area density and the density map, which described the activities of passengers by graphs according to transit fluency, time consumption and transit comfort. And a detailed layout optimized solution was obtained by simulating the operational data of a metro station, which was also verified by the case of Tianfu square metro station. Finally, the result shows that this simulation method can provide more analytical references for designing the layout of metro transfer stations.
