【摘要】：为完善视野受限时的行人疏散理论,探讨了出口指示标志在行人疏散中的作用和其他影响疏散的因素。在前人工作的基础上,进一步阐述了视野受限时的疏散理论模型,统计估算了行人的疏散时间;并利用计算机仿真对比研究了出口指示标志在行人疏散过程中的作用。结果表明,出口指示标志能够明显地影响行人疏散过程中的动力学特征,避免了无出口指示标志时的盲目和绕行现象,优化了行人疏散路径,提高了疏散效率。同时发现,在不同出口宽度下大的视野距离会对疏散起积极作用;初始行人密度较小时,行人数量的变化对疏散时间影响不大;初始行人密度较大时,疏散时间与行人数量间呈线性关系。
[Abstract]:In order to perfect the theory of pedestrian evacuation with limited visual field, the function of exit sign in pedestrian evacuation and other factors affecting evacuation are discussed. On the basis of previous work, the theoretical model of evacuation with limited vision is further expounded, and the evacuation time of pedestrians is estimated statistically, and the function of exit indication sign in pedestrian evacuation is compared by computer simulation. The results show that the exit sign can obviously affect the dynamic characteristics of pedestrian evacuation process, avoid the phenomenon of blindness and detour when there is no exit indicator sign, optimize the pedestrian evacuation path and improve the evacuation efficiency. At the same time, it is found that large visual field distance will play a positive role in evacuation under different exit widths, and the change of pedestrian number has little effect on evacuation time when the initial pedestrian density is small. When the initial pedestrian density is high, there is a linear relationship between the evacuation time and the number of pedestrians.
