表现人员步态的元胞自动机仿真模型

Simulation model of cellular automaton for performance of a person′s gait

针对传统元胞自动机对人员移动特征的刻画不够具体的问题,建立了一种可以表现人员步态的改进型元胞自动机模型。同时,利用更新方式表现人员步频、以移动邻域表现人员的步幅。仿真结果表明:该模型对移动路径及行走速度的表现比传统元胞自动机准确,提高了元胞自动机定量分析的能力,并且具备良好的兼容性,可用于船舶等特殊环境的疏散仿真。

Since the traditional cellular automaton is not specific enough to describe the characteristics of personnel movement, a modified cellular automaton model is proposed. A new updated mode and a neighborhood mode are used to show the stride and frequency. Simulation results show that the proposed model is feasible and accurate, and it can improve the quantitative analysis ability of cellular automaton. The improved model has good compatibility and can be used in the evacuation simulation of special environment such as ships.
