摘要
为实现在行人流疏散仿真模型中更全面地考虑行人的行为特征,文章考虑行人可视域范围对疏散过程的影响,利用元胞自动机建立了行人流疏散模型。通过设置距离参数、可视域范围内个人空间和信息处理空间中行人之间的排斥力和吸引力参数,对不同行人密度、出口宽度和系统规模的疏散系统进行模拟仿真研究并得出其关系数据,达到了行人短时间离开疏散系统的目的。结果表明,系统规模和出口宽度是影响行人流疏散的重要因素。该研究有助于指导相关行人流的疏散。
To make the characteristics of pedestrians behaviors more comprehensive in the pedestrian flow simulation model, this paper investigates the effects of the pedestrian＇s visual field on the evacuation, and establishes the pedestrian evacuation model based on a Cellular Automata. By setting the distance-parameter, the repulsive-parameter of the personal space and the attrac- tive-parameter of the information processing space on the visual field, it simulates the different pedestrian densities, exit widths and system scales and results the relational data, also achieves the purpose of the pedestrian to leave the system in short time. It is found that the system scale and the exit width are key factors on the pedestrian evacuation. The present study is helpful for guiding the pedestrian evacuation.
