The Simulation Research Of Evacuation Based On Agent And Cellular Automata

In recent years,a series of catastrophic events occur at home and abroad show that the risk type in crowded place is more and risk is higher.The catastrophic events that occur in the gathering place of the crowd can cause serious casualties and property damage.Besides this,it will also cause a wide range of people to panic and unstable social and political situation.Therefore,this paper will use the computer simulation technology to study the psychological characteristics and evacuation behavior in the evacuation process,so as to provide theoretical basis and scientific suggestions for the prediction,identification,prevention and control of the risk,to enhance public safety management.Firstly,we construct an evacuation simulation framework based on Agent and cellular automaton,which is on the work of the research of the status quo of the evacuation behavior and model,and considering of the single rules and discreteness of cellular automata and Agent's intelligent.Next,this paper makes a full analysis of the behavior characteristics of Agent in the crowded situation,then finish modeling and simulation of individual crowding evacuation model.On the basis of this,we give a quantitative description of the general existence of panic in the emergency situations to build the panic evacuation model.In real life,there are usually evacuation management mechanisms in the presence of emergency situations.Therefore,it also establish a leader evacuation model,which can describe the evacuation behavior of people with leader.The simulation platform based on Visual Studio describes the various evacuation behavior of the mixed pedestrian.The simulation results show the behavior characteristics and psychological characteristics of the pedestrian evacuation process,And further explore the law of evacuation in each specific evacuation scene by comparing the evacuation situation and simulation data of each model.The simulation results show that the proposed modeling framework,ideas and methods are feasible,and the model has a very strong practical ability,which can reproduce and explain the reality of evacuation.
