摘要/Abstract

摘要： 针对传统社会力模型在人群疏散过程中,难以处理行人轨迹单一、人群松散等问题,提出了一种改进的社会力模型。在原有模型基础上,通过考虑行人疏散过程中运动方向的选择,改进行人疏散过程中的轨迹;然后考虑行人疏散过程中恐慌情绪和吸引力的强度,再现行人疏散运动过程中自组织行为,并进行个人及群组模式下的模拟仿真;引入真实视频中自组织群组形态进行对比,验证群组形态的真实性。实验结果表明：改进后的行人模型更能真实地模拟行人运动轨迹,模型合理有效。

关键词: 社会力模型, 恐慌情绪, 运动方向, 群组模式

Abstract: In view of the traditional social force model, it is difficult to deal with the problems of single pedestrian trajectory and loose crowd in the process of crowd evacuation, and an improved social force model is proposed. Based on the original social force model, the movement trajectory of the person is changed by considering the choice of the movement direction The intensity of panic and attraction in the process of pedestrian evacuation is considered to reproduce the self-organizing behavior in the process of pedestrian evacuation, and the simulations are performed in individual and group mode. The authenticity of the population model is verified by the self-organizing population morphology in the real video. The experimental results show that the improved pedestrian model can simulate the trajectory of pedestrians more realistically and reasonably.

Key words: social force model, panic emotion, the direction of movement, group mode
