基于信息非对称性的小群组紧急疏散行为模拟

摘要

In this paper,we propose a novel method to simulate the behaviors of individuals,social groups and the interactivities between them in emergency evacuation.Firstly,we analyze the factors which may affect individual's behaviors.Then,a unified space is proposed to quantify all these factors,in which the solution process of preferred velocity for different individuals can be executed.Finally,the preferred velocity is solved based on the social group that the individual belongs to and the familiarity of the surrounding environments.The experimental results indicate that the proposed method can simulate the evacuation behaviors of individuals and social groups more realistically.%为了更真实地模拟紧急疏散情况下个体、群组及其间的交互行为,提出一种通用的人群模拟方法.首先分析可能影响个体疏散行为的因素;然后引入统一空间量化所有影响疏散行为的因素,统一不同个体的倾向速度的求解过程;最后根据个体所属的群组及其对环境的熟悉程度的差异性等不同情况对倾向速度进行求解.实验结果表明,该方法能够更真实地模拟个体、群组的疏散行为.
