摘　　要：在人群仿真的研究领域中,社会力模型是由Helbing提出的一种非常经典的微观仿真模型,能够模拟一些常见的人群自组织现象。但社会力模型仍然存在行人震荡、行人重叠等问题,因此许多学者在参数设置、受力范围、算法优化等方面对社会力模型进行了丰富和改进。目前,Gao等提出的一种考虑行人相对速度的改进社会力模型依然是一些学者进行改进社会力模型研究以及各种仿真实验的基础和重要参考。由于Gao等仅通过两个实验就表明了他们的改进社会力模型的优势这一情况欠缺可靠性,以及没有进行更多的人群自组织实验来表明改进后的社会力模型仍然保留原始社会力模型能够模拟人群自组织现象这一能力,因此文中对Gao等提出的改进社会力模型进行了验证性和评估性实验。通过验证性实验验证了Gao等进行的两个实验,证实了该改进社会力模型的优势。文中通过评估性实验证实了Gao等的改进社会力模型保留了能够模拟人群自组织现象的能力,发现并分析了Gao等的改进社会力模型所存在的行人重叠问题。In the field of crowd simulation,the social force model is a very classic micro-simulation model proposed by Helbing,which can simulate some self-organizing phenomenon.However,there are still some shortcomings in the social force model such as pedestrian oscillation and pedestrian overlapping.Therefore,many scholars have enriched and improved the social force model in terms of parameter setting,force range and algorithm optimization.Gao et al.proposed a modified social force model considering the relative velocity of pedestrians,which is still the basis and important reference for scholars to study the improved social force model and various simulation experiments.Since Gao et al.showed the advantages of their modified social force model through only two experiments,which is a little lack of reliability,and there is no more self-organizing experiments to show that their modified social force model still retains the original social force model’s advantage that can simulate the self-organizing phenomenon,this paper did the confirmatory experiments and evaluation experiments for the modified social force model proposed by Gao et al.Two experiments conducted by Gao et al.were verified by confirmatory experiments,which confirm the advantages of Gao et al.’s modified social force model.Through the experimental results of the evaluation experiments,it is confirmed that the modified social force model of Gao et al.retains the ability to simulate the self-organizing phenomenon.This paper also discovered and analyzed the pedestrian overlap problem of the improved social force model of Gao et al.
