| 摘 要： | 量化行人对导向标志的认知作用,不仅有助于分析疏散过程中导向标志对行人疏散的影响,也对人员密集场所安全设施的规划建设具有重要意义。在深入分析行人对导向标志认知过程的基础上,确定了行人对导向标志认知过程的影响因素,并将这些因素引入人员密集场所行人疏散过程建模中,利用元胞自动机提出基于导向标志可见域的行人疏散模型。通过Matlab编程对模型进行实现,并以商场超市作为模拟场景算例进行仿真。结果表明:导向标志的设置有助于减少行人总体疏散时间、个体疏散时间和行人平均疏散距离,提升整体疏散性能。导向标志的设置数量和设置位置对于疏散性能具有一定的影响。 |

| Abstract: | Quantifying pedestrian's cognition of direction signs helps in the analysis of the effects of direction signs on pedestrian evacuating process,and contributes to the planning and construction of safety facilities in crowded places.The influencing factors are identified based on the deep analysis of the cognitive procedure of direction sign by pedestrian.By integrating these factors with the modeling of evacuation,the visible area of direction sign is introduced,and a cellular automation model is established... |
| Keywords: | pedestrian evacuation modeling direction sign crowded place effect of cognition |
