Study on evacuation behavior of bi-directional flow crowd based on tripartite evolutionary game theory
In order to explore the evacuation behavior of bi-directional flow crowd,considering the evacuation commander's management of evacuation process,a tripartite evolutionary game model including the forward flow crowd,the counter flow crowd and the evacuation commander was constructed.The stability of the three parties'strategy selection after participating in the game was analyzed,and the influence of site width,personnel density,cooperation income,counter flow task income,site familiarity,management intensity,accident punishment and other factors on the evolutionary stability of emergency evacu-ation system was explored by numerical simulation,.The results show that the main strategy conversion of the tripartite game has strong linkage.The competition or cooperation strategy of bi-directional flow crowd is mainly influenced by cooperation in-come,counter flow task income and site familiarity.Blindly improving the management intensity of commander may force the commander to give up management.The research results can provide some theoretical support for reducing the counter flow behavior of evacuation personnel and improving the management ability of evacuation commanders.
