双向行人流的多格子模型

摘要

利用1个行人占据6个格子的多格子模型,研究在周期性边界条件的通道中转身侧行行为对双向行人流的影响.结果表明:行人的转身侧行行为可促使同向行人成行,在行人随机向右偏让时,转身侧行行为能提高相变的临界密度,但在行人有意识地向右偏让时,转身侧行行为不能提高相变的临界密度,增大转身侧行的偏向强度反而使之降低.该模拟结果对行人在双向通道中的紧急疏散有一定的指导意义.%Using the multigrid model in which the pedestrian occupies six grids, the effect of sidling is studied for the pedestrian counter flow under periodic boundary conditions. The results show that: the behavior of sidling may promote the lane formation of pedestrians in the same direction. As the pedestrian turns to right in-consciently, the behavior of sidling can improve the critical density of the phase transition, but as the pedestrian turns to right consciously, the phase transition will be reduced.
