In this paper, the impact of crawling on evacuation dynamics is investigated via experiments and modeling. Two types of experiments are implemented, in which pedestrians are asked to escape out of a virtual room with an exit either by crawling or walking. The experiments show that escaping by crawling will increase the average evacuation time. Moreover, it is found that the evacuation time gap of crawling is generally larger than that of walking. To model the evacuation dynamics, an improved heuristic-based model is proposed in which the pedestrians’ shape is represented by multiple connected circles rather than a single circle. Such representation can help the pedestrians keep a safer distance from others. Simulation results are in agreement with the experimental ones.

从房间爬行疏散:实验和建模

在本文中,通过实验和建模研究了爬行对疏散动力学的影响。实施了两种类型的实验,其中要求行人通过爬行或步行逃离带有出口的虚拟房间。实验表明,爬行逃生会增加平均疏散时间。而且,发现爬行的疏散时间差距普遍大于步行。为了模拟疏散动态,提出了一种改进的基于启发式的模型,其中行人的形状由多个相连的圆而不是单个圆表示。这种表示可以帮助行人与他人保持更安全的距离。模拟结果与实验结果一致。
