BRT车站口交叉行人模型仿真研究

Simulation Study on Crossing Pedestrian Model at BRT Station Ports

BRT车站口到达和离去的多方向行人流通常存在交叉现象,特别是在车站人流量高峰时段易造成出入口拥堵,给进出车站的行人带来不便,同时也给车站组织工作造成压力。文章通过分析车站口的行人特性,结合元胞自动机理论提出交织行人元胞的移动更新规则,建立了车站口交织行人的元胞自动机模型,并研究了交织区长度对系统的影响。研究发现,通过改变交织区段的长度可以提高交织行人的速度和临界密度。

The arriving and departing multi-directional pedestrian flow at BRT station port normally presents the crossing phenomenon,susceptible to the congestion particularly at the entrance/exit during the peak pedestrian flow,causing the inconvenience to the station and also bringing more pressure to station organizing work.By analyzing the pedestrian characteristics at station ports,and combined with cellular automata theory,this article proposed the moving update rules of cross people cellular,established the cellular automata model of crossing pedestrians at the station ports,and studied the effect of crossing zone length on this system.The study found that：the speed and critical density of crossing pedestrians can be improved by changing the length of crossing section.
