社会力模型在行人运动建模中的应用综述

A Review of Application of Social Force Model for Pedestrian Dynamics

为研究社会力模型在行人运动建模中的应用状况与存在的问题,系统分析了相关文献,跟踪研究了模型的基本原理、表达式的改进、参数的取值、可行性和模拟结果的真实性。研究显示,社会力行人交通流模型能较好地反映行人流在正常和逃生情况下的状态,模拟结果与实测的行人现象符合,具有很好的适应性和真实性,可为交通设施设计和行人流管理提供参考。最后,总结了该模型的不足与改进方法。

In order to study the development status and existing problems of applying social force model for pedestrian travel,this paper systematically analyzes the relevant literatures,and the model’s fundamentals,expression improvement,parameter values,feasibility and the reliability of simulated results.The research shows that the model can better reflect the phenome-non of pedestrian traffic in normal and evacuation situa-tions,the simulated results are consistent with the ob-served pedestrian flow,and has the better adaptability and authenticity,which can provide reference for the traffic facility design and pedestrian flow management.Finally,the paper summarizes the shortcomings and im-proved method of the model.
