| 摘 要： | 应用改进的格子气模型(即将行人的最大速度扩展到大于1)研究行人的最大速度对过道中单向和双向行人流的影响。模拟结果显示:最大速度为5时所对应基本图的临界密度跟实验值比较符合,说明该扩展是必要的;在一定范围内随着行人最大速度的增大道路的整体通行能力增强同时临界密度减小;双向行人流的时空斑图显示行人最大速度的增大加快了拥堵的形成过程(即缩短了行人从局部拥堵演化为完全拥堵的时间)。

| Abstract: | In the present paper,upgraded lattice gas model in which the maximum velocity of pedestrians is extended beyond one is used to study the effect of the maximum velocity of pedestrians on unidirectional and bidirectional flow pedestrian flow.It is shown by the simulation: When the vmax is 5,the critical density of the corresponding fundamental diagram is in comparatively good agreement with empirical results.With the increase of Vmax within a certain scale,while the overall traffic capacity increases,the crit... |
