摘要 社会力模型广泛应用于人群仿真。针对该模型在人群疏散仿真中存在抖动、穿透现象,分析产生该现象的原因,采用多线程优化的方法改进社会力模型。对于多障碍物场景中行人存在停滞和移动缓慢的现象采用增加导航点优化行人的疏散路径。采用优化的社会力模型研制一个人群疏散仿真软件,该软件可以定义多种人群仿真参数,实现人群仿真。通过该仿真软件对地震疏散情景进行仿真实验,对实验数据进行对比分析,验证了该仿真软件可以推演人群的疏散行为,可以为人群的疏散策略制定提供参考数据。 The social force model is widely used in crowd simulation. For this model, there are shiver and penetration phenomena in crowd evacuation simulation. After analyzing the cause of this phenomenon, the multi-thread optimization method was used to improve the social force model. As pedestrians were slow-moving in multi-obstacle scenes, the auxiliary navigation points were adopted to optimize the evacuation path of pedestrians. A simulated crowd evacuation simulation software was developed using an optimized social force model. The software can define a variety of crowd simulation parameters to achieve crowd simulation. The simulation experiment was carried out on the seismic evacuation scenario, and the experimental data was compared and analyzed. It is verified that the simulation software can deduct the evacuation behavior of the crowd and provide reference data for the evacuation strategy of the crowd.
