摘要: 在行人运动和行人行为观察的基础上,结合社会力模型,把行人运动看作一种自驱动的个体在连续空间中移动的过程。为了解决行人间相互作用力的不足,通过引入行人运动感知域,提出一种行人碰撞避免的解决机制,这种机制能较好解决行人间的相互碰撞行为,防止行人间出现大面积的堵塞现象。仿真实验结果显示改进后的模型能再现正常条件下行人流基本图,并很好地再现了行人流“通道形成”自组织现象。

Abstract: Based on the observation of pedestrian movement and pedestrian behavior, this paper combines with the social force model, and considers the pedestrian movement as a self-driven individual moving process in the continuous space. In order to solve the shortcomings of the interaction force between pedestrians, this paper introduces pedestrian field of perception and proposes a solution to pedestrian collision avoidance mechanism, which can efficiently solve the collision between human behaviors, and avoid the emergence of large area of human clogging. Simulation experiments show that the improved model can represent the basic flow diagram in the normal conditions, and have a good reproduction of lane forming in pedestrian flow.
