封闭性公共场所人群行为多感知模型的构建与仿真

Modeling and Simulation of Crowd Multi-perception Behavior Model in Closed Public Places

现有人群行为仿真软件多采用基于社会力的多智能体建模方法构建人群仿真模型,但在响应环境影响方面却没有提供相应的函数。从认知心理学角度结合作者前期研究得到的人群广义影响力空间逻辑模型,以Sigmoid函数为基础构建了人群个体视觉和听觉感知数学模型,并以典型地铁换乘大厅高峰期发生突发事件后疏导为例,在定义地铁换乘大厅大客量疏导优化目标函数基础上构建了人群疏导仿真模型,根据设定的情景仿真不同疏导策略,仿真结果表明本文所提人群行为多感知模型是有效的。

The social forces-based multi-agent modeling method is used to build the crowd simulation models in most of the existing crowd behavior simulation software systems. From the perspective of cognitive psychology, combined with the spatial logic model of the generalized influence of the crowd obtained by the author’s previous research, and based on the sigmoid function, the mathematical model of the individual visual and auditory perception of the crowd is constructed. Taking the typical subway transfer hall as an example, the objective function of large passenger volume evacuation optimization is established to construct the crowd evacuation simulation model. The simulation results based on the defined scenarios show that the proposed multi-perception behavior model is effective.
