人员停留对含群组人群运动影响实验研究

Experimental study on the influences of pedestrians stop on the movement of crowd with groups

通过开展行人运动实验,对人员停留对群组运动行为的影响进行初步研究。结果表明,人员停留工况中,受到群组及停留人员的影响,人群中个体成员和群组成员的运动速度会下降,同时群组规模越大,行走速度下降的幅度越大。当受到停留人员阻挡时,其他行人会采取绕行行为,个体成员倾向于选择通道边缘绕行,而群组成员的绕行行为与群组规模相关。群组在停留后可能会改变构型尽量聚拢,以尽量避免与后方绕行行人发生碰撞。

The experimental studies on the influences of pedestrians stop on the movement of crowd with groups were conducted in this study.Result showed that the walking speeds of group members and individuals decreased due to the group behavior and the stopped pedestrians.This decrease of walking speed of large group in the crowd is more remarkable.When hindered by the stopped pedestrians,the other pedestrians detoured.The individuals were apt to detour by the side of the stopped pedestrians.The walking behavior of groups when they detoured the stopped pedestrians depended on group size.The large group changed their configuration to gather as much as possible when they stopped,in order to avoid collision with the rear pedestrians.
