Emergency Personnel Evacuation Model and Its Application Based on Cellular Automaton

摘要

In this article, cellular automaton model will be extended and applied to the evacuation of large public venues. First, we analyze the affecting factors in macro approach, such as physical distribution, psychological preferences, bypass behaviors and so on. Then, we apply the model in the process of evacuation in China Pavilion of World Expo after we have established an extended cellular automata model and proved its reliability. Simulation results show that people who do not consider bypass apparently stand in queues during evacuation, and the herd mentality, in general, is to hinder evacuation process to a certain extent, and it is worth noting that a certain percentage of the herd mentality could shorten the evacuation time, and additionally, family behaviors will extend the evacuation time. Finally, according to experimental results, we put forward rational proposals for the personnel evacuation in large public venues and optimize the model.
