在人群交通行为研究领域,社会力模型的改进研究和应用是一个热点问题。为了研究阶梯路段大规模行人运动的状况,文章分析了行人在正常和紧急情况下的表现特征,基于初始社会力模型,通过引入重力分力和边界吸引力,建立了适用于阶梯路段的社会力模型,并提出了符合阶梯路段的期望速度的计算方法。研究显示,本文建立的社会力模型能较好的描述行人在阶梯路段的运动特征,提高阶梯路段大规模人群行为模拟的有效性。

In the field of traffic behavior research of the crowd, researches on the applications and the modification of social force model is a hot topic. In order to study the status of large-scale movement of pedestrians on ladder sections, this paper analyzed the performance characteristics of pedestrians under normal and emergency situations, and established a social force model based on the initial social force model which was applicable to the ladder sections by introducing the gravity component and attractiveness of the border, and proposed a method for calculating the desired speed on the ladder sections. The study has shown that the newly created social force model could better reflect the pedestrian movement on the ladder section and improved the effectiveness of the the behavior simulation on large-scale movement of the pedestrians on a ladder section.
