摘要: 社会力微观行人仿真模型能够体现行 人真实运动情况,但其在模拟拥挤状态下的行 人运动时存在失真及运算效率低的问题。为 此引入有限元分析方法,从模型和算法两方面 对社会力模型进行改进,提出基于有限元理论 的方法与求解步骤。最后应用该方法对通道 内双向行人交通流进行仿真模拟,验证其可 行性。

Abstract: The social force microscopic pedestrian simulation model can capture pedestrians’ real movement conditions, however its accuracy and computational efficiency suffers when applied to simulate pedestrian’s movement in the crowded condition. This paper improves the social force model and its solution algorithm based on the finite element theory. Finally, the paper validates its feasibility by applying the model to simulate bi-directional pedestrian flow in a channel.
