随着中国城镇化进程的推进,举办大型文化活动的数量迅速增加,规模日益增大。此类人员密集场所会大大增加人群拥挤踩踏的风险。但是,目前关于人群踩踏的仿真研究比较少见。为了推演人群的踩踏情景,提出了一种基于心理学原理的人群踩踏仿真模型。该模型考虑了密集踩踏人群中的情绪感染因素,能够模拟人群的踩踏过程,给出了人群踩踏的判决条件。仿真实验以在公园游览的人群为研究对象,对人群的踩踏现象进行了三维情景仿真演示。研究成果有助于管理部门分析如何对密集人群进行管理和部署,为进一步深入研究人群踩踏预案提供了一种新视角。
With the progress of urbanization in China, the number of large-scale cultural activities held by the government has rapidly increased and the scale has been increasing. Such crowded places can greatly increase the risk of crowd walking. However, the current simulation research on crowd stampede is rare. In order to deduce the stampede situation of the crowd, a stochastic simulation model based on psychology was proposed. The model takes into account the emotional contagion factors in intensive trampling of the crowd, which can simulate the stampede of the crowd and gives the judgment of the crowd stampede. The simulation experiment takes the crowd visiting the park as the research object, and carries on the three-dimensional scene simulation demonstration of the crowd’s stampede. The research results help management to analyze how to manage and deploy densely populated populations, providing a new perspective for further studying the crowd stampede.
