[Abstract]:With the rapid development of urban economy, motor vehicles have an obvious growth trend, which brings serious traffic congestion to the city. In order to meet the travel needs of urban residents, the city speeds up the construction of rail transit. The large scale of subway construction and the long construction period determine that subway construction will occupy the scarce road resources for a long time and bring some negative effects. Therefore, it is of great significance to study the traffic diversion and traffic organization of the affected area. This paper studies the traffic organization and signal control during the construction of signalized intersection. This paper focuses on the traffic problems caused by the long-term semi-closed lane of the urban main road intersection. This paper first introduces several construction techniques of intersections, and analyzes the influence of the construction of intersections on people, traffic flow, roads and the surrounding environment, and analyzes the influence of construction barriers on the capacity of intersections. The instantaneous line source model is used to define the influence area of intersection during construction, and the effective traffic organization range is determined. Secondly, several main traffic organization modes in the affected area are discussed, and by using the SUE allocation model based on Logit, the traffic volume transferred from the intersection due to construction can be reasonably allocated to the road network of the surrounding affected area without causing new traffic congestion points. In order to give full play to the potential of the branch network and reduce the saturation of the trunk road, a bilevel programming model with minimum saturation as the optimization objective is established and the genetic algorithm is written to solve the problem, and the single and double traffic organization affecting the branch network in the region is carried out. In order to improve the operation state of the whole regional road network, alleviate the traffic pressure of the construction intersection, and use simple idealized cases to verify the feasibility. Through the analysis of the construction block at the intersection, the reduction of the number of entry and exit lanes leads to the transfer of vehicles, and the existing signal timing scheme is difficult to meet the vehicle traffic, so it is necessary to optimize the signal timing of the flow at the intersections after the transfer. A multi-objective evaluation function based on traffic conflict, number of entry lanes, capacity, delay time and queue length is established to achieve the overall optimal signal timing. Finally, based on the safety analysis of green light and red light snatching caused by countdown signal control, the green light and yellow light do not show the corresponding remaining time when setting the countdown signal light based on the safety point of view. The red light displays the corresponding remaining time. Finally, the traffic organization of the intersection of Yanta North Road and Friendship East Road is studied by using the relevant theory, the influence range is determined, the influence area is reasonably organized in the branch network, and the signal control of the construction intersection is optimized. Using Vissim to evaluate the signal timing scheme, finally set up the construction intersection forbidden left, and combined with the single and double line organization of the road network in the affected area, effectively guide the evacuation of the left turn traffic flow, reduce the inconvenience caused by the intersection left ban, and determine the best signal timing scheme.
