Intersection-traffic control method giving priority to trunk roads

Abstract

The invention relates to an intersection-traffic control method giving priority to trunk roads, which is characterized in that the mode of controlling traffic lights on a trunk road is to simultaneously allow or stop the running of vehicles on all lanes in the same driving direction, and to allow the running of the vehicles in the driving direction of an opposite trunk road respectively; the mode of controlling the other roads is to allow the running of the vehicles on a right-turn lane on the premise of not affecting the running of the vehicles on the trunk roads when the vehicles on the trunk roads are allowed to run, and to allow the vehicles on the other lanes to run when the running of the vehicles on the trunk roads is stopped. The method controls clearance time and clearance modes of different roads according to the road traffic conditions of intersections, and preferentially allows the vehicles on the trunk roads to go when traffic jams occur on the trunk roads. The method has the advantages of better utilizing the traffic capacity of road intersections, effectively ensuring no jams on the trunk roads, improving the vehicle-passing capacity of the intersections and easing the prior traffic pressure.

Description

technical field [0001] The invention relates to an intersection traffic control method with main road priority, which can flexibly arrange the driving flow of each direction and each lane, effectively utilize the traffic capacity of the road intersection, and reduce road congestion. Background technique [0002] Urban road traffic is under great pressure now. Although road conditions and traffic signal facilities have been greatly improved, the problem of difficult driving is still the main problem of urban road traffic. Traffic jams and traffic jams are still prominent problems plaguing urban traffic. Especially in the old city roads of big cities with poor road traffic capacity, the problem of traffic jams and traffic jams is more serious. In order to solve these problems, traffic management agencies have adopted some corresponding road control measures, such as: one-way driving, restricted traffic on some road sections, etc. Although these measures have eased the press...

[0004] However, this control method controls the congested vehicles on the entering road section when the main road intersects with other road planes. Although the congestion at the intersection is all alleviated, the vehicles on the entering road are not Passing through the intersection will still cause pressure on the traffic at the intersection, especially the traffic flow of vehicles on the main road is large, and the short-term restriction will also cause long-distance congestion, especially during peak hours, when the entire road often passes from one intersection to another Full-scale congestion at intersections
