【摘要】：随着北京市城市经济的发展，带来了一系列社会问题，其中交通拥堵成为北京市突出的社会问题。信号交叉口作为城市道路的重要组成部分，在道路衔接中起着举足轻重的作用。初步统计北京市五环之内拥有信号交叉口2000余个，针对北京市信号交叉口进行交通流释放特性研究，对于缓解北京市交通拥堵具有十分重要的作用。针对北京市种类繁多的信号交叉口，本文研究信号交叉口直行车流饱和车头时距影响因素分析及应用工作。研究首先应用正交实验设计方法依据直行车道组车道数量、直行车道宽度、本向道路横断面形式、相交道路宽度等指标进行实验设计，选取合适正交实验表格；然后依据实验设计表格通过北京市信号控制系统，选取目标信号交叉口，获取车辆通行车头时距，，并求出饱和车头时距；应用极差分析方法分析不同影响因素对直行车流饱和车头时距影响程度大小，研究表明对于北京市信号交叉口直行车道饱和车头时距来说影响作用程度按重到轻排序为：相交道路宽度道路横断面形式直行车道数量车道宽度；最后研究给出北京市信号交叉口饱和车头时距计算模型，并进行标定及验证工作。
[Abstract]:With the development of Beijing's urban economy, a series of social problems have been brought about, among which traffic congestion has become a prominent social problem in Beijing. Signal intersection is an important part of urban roads. It plays an important role in road connection. According to the preliminary statistics, there are more than 2000 signalized intersections in the Fifth Ring Road of Beijing. The traffic flow release characteristics of Beijing signalized intersections are studied. To alleviate traffic congestion in Beijing has a very important role. In view of the variety of signalized intersections in Beijing, this paper studies the analysis and application of the influence factors on the saturated headway distance of direct traffic flow at signalized intersections. Firstly, the orthogonal experimental design method is applied to determine the number of carriageways in the straight lane group. The width of the straight lane, the cross section of the road and the width of the intersection road are designed experimentally, and the appropriate orthogonal experimental tables are selected, and then the target signal intersection is selected according to the experimental design table through the signal control system of Beijing Municipality. The time distance of the vehicle head is obtained, and the time distance of the saturated vehicle head is obtained, and the influence of different factors on the saturated headstock distance of the direct flow is analyzed by using the method of range analysis. The results show that the degree of influence on the saturated headway distance of Beijing signalized intersection is in the order of heavy to light: the number of lanes in cross section of intersection road; Finally, the calculation model of the saturated head distance of Beijing signalized intersection is given, and the calibration and verification are carried out.
