摘要： 轨道交通内部行人流运动规律及其基本特征与轨道交通建设与运营组织密切相关，随着我国轨道交通建设和运营规模的不断扩大，轨道交通内大规模、高密度行人流运动对轨道交通安全与组织是一个值得关注的重要课题.本文以现有的社会力模型为基础，对模型参数中的驱动力、吸引力和方向影响进行改进，在模型计算时引入矩形作用范围，提出避免过度重叠的行为规则模型，使该模型能更真实地体现人的行为，并通过轨道交通行人流运动中出现的自动渠化现象和在出口处形成的拱形为例说明模型的有效性.最后使用Visual C+〖KG-*3〗+6.0作为编程工具建立的SubPeds行人流实验仿真分析平台，通过设置虚拟轨道交通单向行人流场景对模型进行仿真，并对仿真数据进行了分析.分析结果表明，本文提出的模型改进方法，更能反映轨道交通中实际行人流的特征.

Abstract: The law and basic characteristics of rail transit pedestrian flow movement are closely related to rail transit construction and operation.Under the background of China’s large -scale rail transit construction and the expansion of operation ground, as a key factor, the safety and organization of mass and high-density pedestrian flow movement in rail transit has gained wide attention.This paper reports a novel excessive overlap avoided behavior rule model based on the existing social force model, through improving the driving force, attractiveness and direction influence in the model parameters, and rectangular scope was also introduced in model calculation to reduce the computing time.This paper examines the conditions for which the novel model can be beneficial to the human behavior reflection in terms of automatic drainage phenomenon appearance and the arch formed in the station of exit in rail transit pedestrian flow motion.Finally, this paper uses Visual C++6.0 to create the SubPeds pedestrian flow simulation experiment platform, by setting the one-way virtual pedestrian flow scenarios, it is shown that the model is simulated and simulation data is analyzed.The results shows that the novel model can be more accurately simulate pedestrian movement.
