【目的】研究不同博弈行为、中心分隔护栏的长度和位置布局对行人流动力学的影响。【方法】考虑行人运动过程中的心理变化，引入博弈和学习策略，用以刻画行人在面对位置冲突时所采取的决策行为，分别建立相应的单向和相向行人流格子气模型。【结果】在单向行人流中，中心护栏长度对行人流无影响；而在相向行人流中，中心护栏的长度和位置布局对行人运动效率具有明显的影响。【结论】在单向行人流的通道中设置中心护栏不会影响行人流的宏观特性，也不会提高行人的整体运动效率；而在相向行人流的通道中，设置中心护栏可以提高行人运动效率，且设置有空隙的两个中心护栏比设置无空隙的单一中心护栏更能提高行人的整体移动效率。

Objective]Considering the psychological changes of pedestrian,the game behaviors and learning strategies are introduced to describe decision-making behavior of pedestrians when they meet location conflicts.[Methods]The corresponding unidirectional and bidirectional pe-destrian flow lattice gas models are established to simulate pedestrian movement,respectively. The influences of different game behaviors,the length and position of central barrier on pedes-trian flow are studied via numerical simulation.[Results]The length of central barrier has al-most no effect on the movement efficiency of the unidirectional pedestrian flow.However,it has an obvious influence on the bidirectional pedestrian flow.[Conclusion]The central barrier has no effect on the unidirectional pedestrian flow,but it can improve movement efficiency on the bidirectional pedestrian flow.In addition,two central barriers are more effective to im-prove the total movement efficiency of pedestrian flow than that of one central barrier.
