Simulation Model Of Crowd Behaviour And Psychological Game In Crowd Stepping Process

Since the 21 st century,the quality of life of the people has been improving with the development of economy,the forms of activities in public places have become more and more diversified,and the number of people gathered as a result of these activities is increasing.However,there are many hidden safety hazards in crowded public places.The biggest problem is the stampede accident.A crowded stampede accident is a sudden event,and once it occurs,it will have immeasurable consequences and losses,which will have a serious impact on society.Therefore,studying the causes and risk prediction of crowded stampede accidents is a problem worthy of continuous research and exploration.By exploring the causes of stampede and giving accurate preventive measures,most crowded stampede accidents can be effectively avoided.In real life,most of the practical exercises have cost a lot of manpower,material and financial resources and have little effect.On the one hand,computer simulation technology can reproduce the scene of the accident,on the other hand,it can simulate the scene of crowd evacuation.Based on the statistics of crowd trampling case data,combined with existing literature,management,psychology and other multidisciplinary knowledge,this paper conducts research and analysis on the formation mechanism and evolution process of crowd trampling accidents.Based on basic models such as typical risk theory,crowd dynamics,and game theory,combined with on-site investigations,software simulations and other methods for empirical analysis and quantitative analysis.Finally,Unity is used to simulate the crowd stampede accident based on psychological game.The main research contents of this paper are as follows:1.Firstly,it introduces the purpose and significance of stepping simulation simulation in the process of studying crowd evacuation,and analyzes the current research status of crowd evacuation simulation simulation at home and abroad.At the same time,the three types of basic models involved in this article(cellular automata,social forces,and intelligent bodies)are introduced theoretically.2.Through online search,we have counted all domestic and foreign news reports or written cases of crowded stampede accidents from 2000 to 2018,and analyzed from the four perspectives of the place where stampede occurred,the cause of the accident,casualties,and crowd behavior.According to the typical risk theory,a quantitative formula for the stampede risk of the area is proposed,and this quantitative model is verified by experiments in different places through the Pathfinder evacuation simulation software,which provides a basis for establishing a stampede simulation model.3.Propose a crowd psychological game model based on rationality and irrationality.It briefly introduces the elements of a game,discusses the behaviors of the crowd in different mental states between rational and irrational,and proposes a decision-making model based on the psychological-behavior game of rational and irrational crowds.Using Unity software for system development,based on the agent model,adding the quantitative model and psychological game proposed in this article,to build a crowd crowding stampede accident simulation model to more realistically reflect the problems and possible consequences of the crowd evacuation process.Provide reference for safe evacuation of crowds.
