轨道交通车站十字冲突区域优化研究

Optimization of Cross Conflict Area in Rail Transit Station

为解决轨道交通车站冲突问题,通过对某轨道交通车站十字冲突区域行人行为的研究,分析了冲突区域的瓶颈竞争,建立了行人步行社会力模型。从优化步行空间方面,提出了十字冲突区域占地面积优化模型和环岛行人流组织方案两种优化方法。运用Massmotion软件对上述优化方案进行仿真,提出了行人滞留量、行人速度、行人密度等评价指标,比较了不同优化方案的实施效果。结果表明,扩大十字区域的面积可以有效增加行人通行空间,行人流平均强度降低13.1%,行人平均密度降低21%;建设环岛对行人提前分流,有效提高行人速度,行人流平均强度降低27.1%,行人平均密度降低27%。

In order to solve the conflict problem of rail transit station, the pedestrian behavior in the cross conflict area of a rail transit station was studied, the bottleneck competition in the conflict area was analyzed, and the pedestrian walking social force model was established. From the aspect of pedestrian space optimization, two optimization methods are put forward, which are the area optimization model of cross conflict area and the pedestrian flow organization scheme around the island. Massotion software was used to simulate the above optimization schemes, and the evaluation indexes of pedestrian detention, pedestrian speed and pedestrian density were proposed, and the implementation effects of different optimization schemes were compared. The results show that expanding the area of the cross area can effectively increase the pedestrian space, the average intensity of pedestrian flow is reduced by 13.1%,and the average density of pedestrian is reduced by 21%;the construction of ring island can effectively improve the speed of pedestrians, and the average intensity of pedestrian flow is reduced by 27.1% and the average density of pedestrian is reduced by 27%.
