| 摘 要： | 交通堵塞影响现代城市生活，本文针对车道被占用对城市道路通行能力的影响，分析交通视频信息，构建实际通行能力模型，获取事故点横断面实际通行能力的变化。运用 Mann-Whitney 检验法对同一横断面不同车道被占用对实际通行能力的影响进行显著性差异分析；结合车流波动理论知识，建立车辆排队模型，得到排队长度与实际通行能力、事故持续时间以及路段上游车流量间的关系式。

| Abstract: | Traffic jam has a great influence on modern urban life. Aiming at the effect of lane occupation on the ability of transportation in cities, this essay analyzes the traffic-information videos and sets up a real traffic ability model to get the changes of the transverse of accident point. Then based on the Mann-Whitney test, we analyze the significant differences at the same transverse of the influence of occupied road. Besides, we learn from the traffic flow wave theory and then build a Vehicle queue model of the block. Thus we get the relationship among the length of the queue, the real traffic ability, the time that an accident lasts and the Vehicle flow rate on the upstream road. |
