| 摘 要： | 针对车道被占用对城市道路通行的影响,通过对所给视频数据的提取,分析不同时刻的标准车当量,使用修正系数法和单因素方差分析法,建立道路通行能力、单因素方差分析、占用不同车道导致通行能力差异的多因素分析、传统的累计到达-离去等模型,得到车道被占用时两视频道路的实际通行能力,车辆排队长度与事故横断面实际通行能力、事故持续时间和路段上游车流量间的关系式,并分析两视频实际通行能力的差异,最终利用传统的累计到达-离去模型,求得车辆排队长度到上游路口的时间。

| Abstract: | This paper aims to analyze the impact of lanes being occupied on urban road capacity. Firstly, it extracts the data of given videos and analyzes passenger car unit at different period. Then correction coefficient method and one-way analysis of variance are used to establish model of urban road capacity, model of one-way analysis of variance, model of multivariate analysis of variance when differ- ent lanes were occupied which caused the different capacities and model of traditional cumulative reach-leave. At last the paper obtains the actual passing capacity of two videos, the relationship among actual capacity of cross-section when accident occurred, the duration, traffic flow at the upstream intersection with vehicle queue length and makes use of model of traditional cumulative reach-leave to calcu- late the time when queue reaches the upstream intersection. |
