| 摘 要： | 以无灯控行人过街对交通流影响为分析目标,在综合考虑行人穿越行为及车辆行为的基础上,建立了相应的行人及车辆元胞自动机模型规则,尤其是在模型中提出了行人等待区的概念及基于等待区内有无行人的车辆行为规则。以上述模型为基础,通过对不同行人产生概率及速度快的行人比例情况时路段交通流演化趋势进行了仿真。

| Abstract: | In order to analyze the effect of street crossing pedestrians to traffic flow where signal lamp is not used,this paper has built the pedestrian CA model and vehicle CA model in which pedestrian behaviors and vehicle actions are considered.The concept of pedestrian waiting area is proposed and its effect is considered when building vehicle CA action rules.In modeling the fundamental diagrams of traffic flow with different pedestrian arriving ratio and pedestrian speed ratio are presented by numerical simulation. |
