改进的城市人行道双向行人流元胞自动机模型

为了更好地描述城市人行道双向行人流的交通运行特性，为步行交通服务，在考虑行人前进、换道、位置交换、侧向前进、后退等这些常见行为的基础上。利用Moore邻域的方法，结合行人运动过程中呈现的智能、灵活、复杂等特点给出行人运动规则，建立改进的城市人行道双向行人流元胞自动机模型。通过计算机模拟考察位置交换、侧向前进行为对模型的影响，并对模拟给出的双向行人流速度、流量等参数进行讨论。结果表明，位置交换、侧向前进的引入使模型对行人行为的考虑更加全面：提出的模型在模拟高密度的双向行人流方面有很好的适应性．能够给出合理的双向行人流交通运行参数。

Improved Cellular Automaton Model For Urban Walkway Bi-directional Pedestrian Flow

In order to describe traffic operation characteristics of bi-directional pedestrian flow in urban pedestrian walkways and work for walking,authors proposed an improved cellular automaton bi-directional pedestrian flow model. This model takes into account many basic pedestrian behaviors,forward move,side stepping,position exchange, lateral-move and step back,and,using Moore neighborhood method,provides regulations of pedestrian movement combining with the characteristics of walking process,for instance,intel...
