摘要
近年来,狭窄空间疏散的研究引起了越来越多研究者的关注.因地铁隧道疏散平台空间狭窄、环境黑暗,行人在运动时往往需要寻找依靠物来保持运动的稳定性,而墙体就是行人最主要的依靠物之一.文中构建了考虑沿墙行为的拓展的元胞自动机模型,在传统模型的基础上融入了行人的沿墙倾向,并设计了多速度的运动规则.结果表明,沿墙倾向的增大会使人员疏散时间先减少再增加最后保持稳定,人流中墙体敏感型行人的增多会使疏散时间增加,但同时极大地提高了疏散的安全性.
Abstract
In recent years,the study of evacuation in subway tunnels has attracted the attention of more and more researchers.Due to the narrow space and dark environment of the evacuation platform in subway tunnels,pedestrians are prone to looking for reference objects during movement for keeping stability,and the wall is one of their main reference objects.This article constructs an improved cellular automata model for pedestrian evacuation on the subway tunnel platform,incorporating pedestrians'wall inclination based on the traditional model,and designing movenment rules with multiple speeds.The results show that the increase in the tendency to walk along the wall will first reduce the evacuation time,then increase it,and finally maintain a stable evacuation time.The increase in sensitive pedestrians in the flow of people will increase the evacuation time,but at the same time greatly improve the safety of evacuation.
