本文在考虑行人视野范围的随机偏走格子气模型基础上,引入行人避让行为,提出改进的格子气模型,对轨道交通车站通道内的对向行人流进行仿真研究。模型不仅能体现通道内对向行人的自组织行为,重现行人流分层现象,还可以应用本模型分析通道内行人流堵塞现象形成机理。模拟结果发现,在行人高密度条件下,通道墙壁边沿首先形成堵塞,并逐步向通道中央演化,最后导致整个通道堵塞。仿真模型和分析结果对理解对向行人流的动态演化过程,提高轨道交通车站通道内对向行人流的走行效率有一定帮助。
In this paper, based on the random partial lattice grid model considering pedestrian field of view, this paper introduces the pedestrian avoidance behavior and puts forward the improved grid gas model to simulate the opposite pedestrian flow in the railway station channel. The model can reflect not only the self-organizing behavior of pedestrians in the corridor but also the stratification of pedestrians. The model can also be used to analyze the formation mechanism of clogging phenomenon in corridor. The simulation results show that under the conditions of high pedestrian density, the edge of the channel wall first forms a blockage and gradually evolves to the center of the channel, finally resulting in the blockage of the entire channel. The simulation model and the analysis results are helpful to understand the dynamic evolution of the pedestrian flow and improve the traveling efficiency of the pedestrian flow in the rail transit station.
