中文摘要:

为了探究视野受限条件下的人群疏散过程,提出了一种基于分类感知的行人疏散模拟方法。首先基于行人视野状况建立人员分类感知区域,量化视野受限因素对人员疏散行为和运动特征的影响,随后在Unity3D仿真平台上基于社会力模型构建视野受限环境中的行人疏散模型,并通过对比典型疏散行为与疏散时间验证模型的可靠性。仿真结果表明:行人疏散时间随着可视半径的增大而降低,且下降幅度逐渐减小;出口宽度增加对疏散时间的影响取决于当前的能见度距离和出口宽度;多个疏散出口均匀分布有利于提高整体疏散效率;能见度较差时的疏散时间与疏散场景周长呈正相关,而能见度较好时的疏散时间取决于初始人员到出口的距离。

英文摘要:

A simulation method based on classified perception is proposed to investigate the evacuation process of pedestrians under limited visibility conditions. A classified perception range is first established based on the view field conditions of individuals, and the influence of the visibility factor on evacuation behavior and movement characteristics is quantified. Based on the social force model, an evacuation model for view-limited conditions is established on the Unity3D platform. Moreover, the reliability of the model is verified by comparing the typical evacuation behavior and the corresponding evacuation times. The simulation results indicate that the evacuation time of pedestrians decreases with the increase of visible radius, and the magnitude of the decrease gradually decreases. The performance of increasing the exit width on evacuation time depends on the current visibility distance and exit width. The uniform distribution of multiple evacuation exits is beneficial for improving the overall evacuation efficiency. The evacuation time is positively correlated with the perimeter of the evacuation scene under poor visibility conditions. In contrast, the evacuation time depends on the initial distance of the individual to the exit under good visibility conditions.
