摘　　要：针对公共通道行人非理性切向变道行为问题,提出了一种基于行人交互特征的行人非理性切向变道行为效应仿真方法.结果表明,中密度状态下切变行为效应最大,通行速度波动最大,但存在少数人行为优势现象;当非理性切变行为占少数时,其切变行为效应为正,反之为负.低密度状态比高密度状态更容易发生切变行为,但频率较小,影响不显著.一般来说,行人平均速度的波动取决于切变行为.Aiming at the problem of irrational tangential lane-changing behavior of pedestrians in public passageways,this paper presents a simulation method of irrational tangential lane-changing behavior effects based on pedestrian interaction characteristics.The results show that the tangential lane-changing effect is the highest and the traffic speed fuctuates the most in the medium density state,but there is a phenomenon of minority behavior advantage.When irrational tangential lane-changing behavior is in the minority,it shows positive lane changing effect,and negative tangential lane-changing effect on the contrary.The low-density state is easier to change lanes than the high-density state,but the frequency is smaller and the effect is not significant.In general,the fluctuation of pedestrian average speed depends on the behavior of tangential lane-changing.
