Abstract

Understanding on the movement characteristics of pedestrians is important to improve their safety levels. Generalized centrifugal force model is selected to simulate the pedestrians passing through bottlenecks. The bottleneck width and the number of pedestrians are considered to measure their impact on the traffic efficiency on the bottleneck. Linear relation between flow and bottleneck width is observed and the number of pedestrians show no significant impact on the flow. With the increasing bottleneck width, the density in the front of the bottleneck entrance decreases. More pedestrians result into higher density in the measurement area. The findings can help researchers have a deeper understanding on the pedestrians’ movement and bring some guidance to design the buildings.
基于广义离心力模型的行人通过瓶颈仿真
了解行人的运动特征对提高其安全水平具有重要意义。选择广义离心力模型来模拟行人通过瓶颈的过程。考虑瓶颈宽度和行人数量对瓶颈上交通效率的影响。流量与瓶颈宽度呈线性关系,行人数量对流量无显著影响。随着瓶颈宽度的增大,瓶颈入口前方的密度减小。行人越多,测量区域的密度越大。研究结果可以帮助研究人员对行人的运动有更深入的了解,并为建筑的设计提供一些指导。
