Method for optimizing control of switching mode of traffic signal light

Abstract

The invention relates to a method for optimizing control of a switching mode of a traffic signal light, which comprises the following steps: releasing and stopping all driveways on a same entering road at the same time; releasing the driveways in the opposite direction of the same road respectively, and allowing vehicles on other roads to pass through an intersection under the condition that the travel of the vehicles on the released roads is not obstructed; and displaying the travel directions of different driveways on the same entering road by an electronic display and adjusting the travel directions at any time so as to balance the traffic flow of each driveway or in each travel direction. By adopting the method, the traffic capacity of the road intersection can be better utilized to improve the traveling speed of vehicles to pass through the intersection and improve the traffic condition of the intersection.

Description

technical field [0001] The invention relates to an optimal control method for switching modes of traffic signal lamps. 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 pressure on road traffic. But still can't fundamentally avoid the occurrence of traffic jams and traffic jams. Often a poor intersection will quickly become the cause o...

Problems solved by technology

[0004] However, due to this control method, the lanes in different directions of the same approaching road are released separately, and the switching period of each direction is relatively long, and some intersections will occur during the switching process of different vehicles on different roads, which seriously affects the safety of vehicles passing through the intersection. The driving speed seriously restricts the traffic capacity of the intersection

In addition, because the vehicles are blocked on the entry road, these vehicles have not passed the intersection, which still puts pressure on the traffic at the intersection, especially the flow of vehicles on the main road is large, and the short-term restriction will also cause long-distance congestion. Especially during the peak period, there is often a phenomenon of overall congestion of the entire road from one intersection to another
