改进的元胞自动机人员疏散仿真模型研究

Personnel Evacuation Simulation Research based on an Improved Cellular Automaton Model

近几年来,地震、火灾等自然灾害频繁发生,恐怖袭击事件突发频率也呈日益攀升之势,公共安全问题成为社会热点,灾难突发时人员疏散问题的建模与仿真技术成为研究热点。立足已有的元胞自动机模型,充分考虑了人员在疏散时的心理特点和行为特点,提出了一种改进的元胞自动机模型,通过改进的元胞自动机模型对人员疏散问题进行建模与仿真,更加真实再现了行为人在紧急疏散时表现出来的从众性和自组织性,其研究成果为人群疏散仿真研究提供了有力支持。

Nowadays, public safety has already attracted great attention, especially when some natural disasters, like earthquake, fire accident, and other emergency, happen more and more frequently. In case of this situation, personnel e- vacuation in the populated areas has become the core issue, during research. Setting up upon the traditional Cellular Au- tomaton （CA） model, this paper discusses an improved CA model which takes the interaction between people and the envi- ronment into account. Using the new model can simulate the crowd psychology and provide a more reliable theory to sup- port the CA simulation model.
