Study On The Crowd Evacuation Model In Public Places Based On Multi-Agent Approaches

In China with the largest population of the world,we often see a high density of the crowd gathered in some public places,in which these populations are highly concentrated in the public places hidden great security risks.Usually,the high density of population aggregation will not cause serious problems,but if people gathering place in case of emergency will lead to many injuries and property losses,and even personnel casualty and extremely painful adverse consequences.Therefore,how to quickly and effectively evacuate the mass is a very important and very practical research topic with a great significance.This paper will specifically describe the model of crowd evacuation in public places based on multi-Agent in the following courses: analyze the traditional route guidance algorithm,and design the algorithm for the crowd evacuation under the emergency;analyze and conclude the crowd psychology and behavior under the emergency from many aspects according to their similarity and then divide into three group;on the basis of the group and individual behavior,in addition to the optimization strategy or evacuation guidance algorithm,the paper will establish the evacuation the model of crowd evacuation in public places based on multi-Agent;by using Netlogo software platform,this paper designs and realizes crowd evacuation simulation system in public places;optimizing the evacuation model based on the PSO algorithm and practicing it on Netlogo the soft platform.To sum up,this paper will set up and improve the model based on the modeling method of multi-Agent for a crowd evacuation under the emergency,and then put the evacuation strategy and common route guidance algorithm into the model,and finally research the above phrases.The results of this study in a certain extent enhance the crowd safety evacuation speed in public places under the emergency,and provides three kinds of emergency evacuation method,which will promote the follow-up in-depth study of crowd evacuation in public places under the emergency with the certain reference value and practical experience.
