| 摘 要： | 以元胞自动机模型为基础，在传统的车辆换道规则上，引入驾驶人行为因素，根据不同区域交通流特点和驾驶行为特点，给出了不同的车辆换道规则，建立了一种适用于城市道路偶发性拥堵交通流行为分析的元胞自动机改进模型。并利用该模型，模拟分析了偶发性拥堵发生时不同车流密度的车辆排队和平均车速情况。

| Abstract: | The behavior of the driver was considered as the rule of the driver change of lanes, and the new rule of the changes of lanes with the combination between the driver behavior and the coincidental traffic was put forward, then a improved cellular automaton model was put forward, the model was proposed to describe the characteristics of coincidental traffic jams.By the proposed model,the velocity of traffic flow and the length of vehicle lines by coincidental traffic jams was simulated,and the results of the simulation was proposed. |
