摘要
为了提高虚拟行人在疏散仿真中路径规划的智能性,在微观仿真框架下提出一种基于个体心理的实时路径规划方法.该方法根据真实行人的认知模式建立以个体为中心的环境认知域,动态获取其周围环境的人群密度、危险强度等相关信息;进行路径规划时,采用mental cost综合考虑了疏散时间耗费、路径安全性以及自主行动能力等因素对路径选择的影响,为每个个体生成一条其主观认为"最优"的路径;在疏散过程中,虚拟行人能够根据动态更新的现场信息,通过重规划对初始疏散路径进行调整.基于个体认知域与mental cost在导航图中搜索路径,提出了mental A*搜索算法,可以进行实时规划.最后针对不同疏散场景进行了仿真实验,验证文中方法的有效性与可扩展性.
