摘要:
为解决基于传统社会力模型的应急疏散模拟研究中没有考虑环境和行人主观因素影响，并且可视化效果不佳的问题，提出1种基于改进社会力模型的地铁站火灾应急疏散VR模拟方法，引入环境作用和感知影响因子改进社会力模型，设计基于导航网格的人群疏散路径实时规划算法，建立人群应急疏散虚拟现实模拟方法，研发原型系统并开展实验分析。研究结果表明：改进社会力模型的人群疏散时间考虑客观环境和行人主观因素影响，路径实时规划平均所用时间为25 ms，支持实时人群疏散VR模拟。研究结果可为地铁火灾应急疏散决策分析提供技术支撑。
Abstract:
In order to solve the problem that traditional social force model-based emergency evacuation simulation studies,which fail to consider the influence of environmental and pedestrian subjective factors and poor visualization effect,a virtual reality (VR) simulation method for the emergency evacuation of subway station fire based on the improved social force model was proposed.The social force model was improved by introducing into the environmental effect and perceived impact factors,and a real-time planning algorithm for crowd evacuation path based on the navigation grid was designed.A VR simulation method for the crowd emergency evacuation was established,then a prototype system was developed,and the experimental analysis was carried out.The results showed that the influence of objective environmental and pedestrian subjective factors was taken into account in the improved social force model crowd evacuation time,and the average time of real-time path planning was 25 ms,which supported the real-time crowd evacuation VR simulation.The research results can provide technical support for the decision analysis of emergency evacuation in subway fire.
