摘要

基于方向考虑与当前单元相关的周围行人密度，提出了一种元胞自动机模型来模拟具有多个出口的房间中行人的疏散行为。数值结果表明，行人密度和可视区域半径是影响疏散时间的两个重要因素。研究发现，盲目地选择行人密度较小的方向可能会导致疏散时间的增加。

Simulation of Exit Choosing in Pedestrian Evacuation Using a Cellular Automaton Model Based on Surrounding Pedestrian Density

A cellular automata model is proposed to simulate the pedestrian evacuation behavior in a room with multiple exits by considering the surrounding pedestrian density related to current cell based on the direction. The numerical results show that the pedestrian density and the radius of visual area are two important factors in an evacuation which can affect the evacuation times apparently. It is found that blindly constant choosing the direction with smaller pedestrian density may lead to an increase of evacuation time.
