人员疏散出口选择行为的演化博弈模型

Evolutionary game model of pedestrians' behavior of seletion of exits

为了研究多出口条件下疏散人员出口选择这一动态过程,在元胞自动机模型的基本框架下,建立基于演化博弈理论的疏散仿真模型,模型中采用最优反应动态机制来研究疏散人员出口选择的演化过程。最后通过仿真实验分析了出口保持率,视野范围以及初始策略对出口选择的影响。实验结果表明,该模型能够较明显的反应疏散过程中疏散人员出口选择的动态过程。

In order to study the dynamic process of evacuation＇s selection of exits with multiple exits, an evacuate model based on evolutionary game theory is designed, In this model, evacuation＇s behaviors of the exits selecting is described by the best-response dynamics. The influence of the probility to remain exports, the vision range and the initial strategy has been analyzed. The simulating results show that this model can give more effective dynamic process of evacuation＇s exit choice behavior during the evacuating process.
