摘　　要：对大量人群的集体运动行为进行理论研究在辅助交通管理和基础理论研究方面都具有重要意义。当人流聚集,密度达到一定程度时,运动的个体之间的相互作用难以避免,而这种相互作用往往会引发一系列自组织现象。基于通用的社会力模型,改进的社会力模型额外考虑行人的运动随机性对人群集体运动的影响。该模型可以更真实地模拟人流的实际运动行为。基于改进的社会力模型,详细模拟人群在对向运动过程中形成的自组织现象,特别关注人流对向过程中的行道形成现象,研究人行道的宽度、人群密度等因素对该过程中人群自组织行为的影响。The study on pedestrian behavior is very important for both of the fundamental research and traffic management.With increasing pedestri-an density,the interactions among humans are inevitable,which often leads to self-organization of crowd dynamics.Based on the popular social force model,the modified social force model includes the important impact of randomness on the pedestrian behavior,and can simu-late the collective movement of pedestrians more accurately.Based on this model,systematically studies the self-organization of pedestrian motion when two groups of pedestrian move along the opposite directions,especially concerning the Lane Formation behavior.Investigates the influences from the widths of the pavement and the crowd density on the self-organization of pedestrian motion.
