| 摘要: |
| 在行人交通流格子气模型的基础上,考虑行人视距和潜意识行为提出了视距和潜意识行为作用的行人流格子气模型,并进行计算机数值模拟.结果表明,在行人交通中,潜意识和视距对行人交通的影响非常重要,尤其是视距对行人交通的影响更为明显.考虑行人视距的作用可以较大幅度的提高行人的平均速度,考虑潜意识的作用在一定程度上可以有效缓解堵塞的发生,同时考虑潜意识和行人视距的作用,不仅可以提高行人的平均速度,也可以有效的缓解堵塞现象. |

| Abstract: |
| Based on Pedestrian Flow Lattice Gas Model, and taking into account the pedestrian sight distance and subconscious behavior, the thesis puts forward the Pedestrian Flow Lattice Gas Model, which refers to the roles of sight distance and subconscious behaviors.As the Computer numerical simulation shown, the sight distance and subconscious behaviors play important roles in the pedestrian flow, in which sight distance have a more obvious effect.The numerical simulations on considering sight distance or subconscious behaviors alone as well as considering sight distance and subconscious behaviors at the same time show that sight distance can relatively substantially improve the average speed of pedestrians, and subconscious behaviors, to a certain degree, can effectively relieve the congestion.If we take into account the sight distance along with subconscious behaviors, not only the average speed of pedestrians can be improved, but also the congestion can be effectively relieved. |
