摘要/Abstract

摘要： 为研究瓶颈处双向行人流的自组织现象,分析影响行人流量的因素,对RVO (Reciprocal Velocity Obstacles)模型进行改进,提出了一个改进的瓶颈处双向行人流模型。根据RVO模型中出现的问题,提出改进方法,建立了基于Unity 3D的地铁中穿越瓶颈的双向行人流仿真模型。利用改进的模型对地铁站上下车时双向行人流进行仿真,结果表明该模型能够较真实地模拟地铁站瓶颈处双向行人流的自组织现象,发现行人流量随瓶颈宽度线性增加。该研究为疏缓地铁站内瓶颈处拥堵提供了理论依据。

Abstract: An improved bi-directional pedestrian model based on reciprocal velocity obstacles (RVO) is proposed to investigate self-organization phenomena for bi-directional pedestrian flows crossing bottlenecks, and the influencing factors of pedestrian flow are analyzed. According to the RVO model problem, an improved method is constructed. The model of bi-directional pedestrian flows crossing bottleneck in subways based on Unity 3D is established. Based on this improved model, the bi-directional pedestrian flows crossing bottleneck in subways is simulated. Simulation results indicate that the model can veritably simulate self-organization phenomena for bi-directional pedestrian flows crossing bottlenecks in subways and pedestrians flow is an increasing linear function of bottleneck width. The present study provides theory evidence for mitigation of bottleneck congestion in subways.

Key words: pedestrian traffic, bi-directional flow, bottleneck, RVO model
