| 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 pedes- trian simulation model can capture pedestrians＇ real movement conditions, however its accuracy and computational efficiency suffers when ap- plied to simulate pedestrian＇ s movement in the crowded condition. This paper improves the so- cial 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 chan- nel. |
