[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.
