Study On Evacuation Simulation Models Of Gymnasium

With social development and economic prosperity, the sports building is increasing, becoming an integrated complex with multi-functions. Stadium as personnel-intensive sites, Once disaster occurs, while the evacuation does not occur in time, it may result in a difficult evacuation and cause serious injury to human, huge economic losses. Therefore, the evacuation safety has become a thorny issue in recent years, but also is a public security concern.The paper define the individual as AGENT, AGENT-based modeling is used in this paper. First, researches have analyzed the structure features of gymnasium, behavior and psychology of people, it has researched the typical group behavior. The evacuation modeling used AGENT technology build individual modeling and used cellular automata making grid generation.Secondly, according to the impact of the degree of unimpeded exits to the evacuation, this paper made the evacuation type of people in a single case with two exits , the case has simulation the behavior of people by three aspects: two unimpeded exits, two part of unimpeded exits, one unimpeded exits and present three kinds of individual decision-making model, it has analysis the behavior of people at different case. As the result of the research, the structure of the exits will affect the efficiency of evacuation.Finally, this paper make the research with full flow exits, special psychology and behavior in evacuation are simulated including going with the crowd, sub-group behavior,counter-current behavior, gather-together behavior. Simulation has been carried out based on the four kinds of special behavior, the disadvantages of special behavior are analyzed; As the result of the simulation, the severe psychology of going with the crowd and sub-group will cause passive route choices and result in jamming. The model also can reflect the character of arching, clogging, casualty phenomena etc.This paper study the evacuation based on the structure and individual psychology behavior. Through the simulation found that the degree of unimpeded exits and group behavior impact the efficiency of evacuation, the two experiments can reflect the true reality of the evacuation.
