Studies of past accidents have revealed that various elements such as failure to identify hazards, crowd behaviors out of controlling, deficiency of the egress signage system, inconsistency between process behavior and process plan, and environmental constraints, etc. affected crowd evacuation. Above all, the human factor is the key issue in safety and disaster management, although it is bound to other factors inextricably. This paper explores crowd behaviors that may influence an urgent situation, and discusses the technique applied to the crowd prediction. Based on risk rating relative to crowd density, risk plans for different levels are proposed to dispose the potential threats. Also practical crowd management measures at different risk levels are illustrated in a case of a metro station in China. Finally, the strategies for crowd security management are advised that all stakeholders are amenable to form risk consciousness and implement safety procedures consistent with risk plans professionally and scientifically. 展开更多

对于人群仿真中的人物角色来说,如果所有的虚拟人物外观都一样,那么就会给人简单复制品的感觉,真实感较差。研究人群角色外观的多样性问题,分别从角色模型多样化,纹理多样化和姿态动作多样化等方面进行讨论,采用Hasler模型库实现角色身... 对于人群仿真中的人物角色来说,如果所有的虚拟人物外观都一样,那么就会给人简单复制品的感觉,真实感较差。研究人群角色外观的多样性问题,分别从角色模型多样化,纹理多样化和姿态动作多样化等方面进行讨论,采用Hasler模型库实现角色身高以及体型的差异化,通过纹理模板实现角色外观的多样化,并通过嵌入骨骼技术为模型赋予不同动作。实验结果表明本方法可生成效果较好、外观各异、动作多样的虚拟人群。 展开更多
