摘　　要：在在灾害发生时,安全高效的疏散人群是提高公共安全的重要保障。因此有效可行的疏散仿真方法具有深刻的理论和现实意义。当前主流方法较少考虑与疏散相关的灾害动态演化,为此提出了DERR(Dynamic Evacuation Route Replanning Based on Psychology)方法。DERR方法围绕人群的避灾心理参数进行相关研究,利用A*寻路算法,实时根据灾害区的变化对人群的疏散路径重新规划和优化,以达到更加安全疏散的目的。通过仿真实验展示了本方法在灾害演化下的疏散模拟过程,同时心理避灾参数的加入也使得仿真结果更加贴合现实。Evacuating people safely and efficiently during disasters is the important guarantee to public safety,and the effective and feasible evacuation simulation method is theoretically and practically significant.The main methods seldom consider the dynamic evolution of disasters,so a dynamic Evacuation Route Replanning Based on Psychology(DERR)method is proposed.DERR method focuses on the psychological parameters of disaster avoidance of people.According to the change of disasters area,DERR can perform the real time evacuation process by using A*routing algorithm to re-plan and optimize the evacuation path.The simulation experiment shows the evacuation process of this method.The psychological parameters of disasters avoidance make the simulation results closer to reality.
