Example Embodiment

[0022] The following describes the technical solutions in the embodiments of the present invention clearly and completely with reference to the accompanying drawings in the embodiments of the present invention. Obviously, the described embodiments are only a part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those of ordinary skill in the art without creative work shall fall within the protection scope of the present invention.

[0023] The embodiment of the present invention provides a traffic light optimization scheduling method, such as figure 1 As shown, it mainly includes:

[0024] Step 1. Initially set the basic scheduling rules for traffic lights in each direction of the intersection, so that the traffic lights will display the green and red lights in a certain order and time interval.

[0025] Those skilled in the art can understand that the basic scheduling rules c...

Abstract

The invention discloses a traffic light optimization scheduling method and system. The relevant method comprises the steps that a basic dispatching rule of the traffic lights at all directions of theintersection is initially set, so that the traffic lights sequentially display the green light and the red light according to a certain sequence and time intervals; the vehicle conditions of lanes inall directions are collected through preset information acquisition equipment, and a mode comparison mode is adopted, and a vehicle state or a vehicle-free state of the lane in each direction is determined; and dynamic optimization is carried out on the basic dispatching rule according to the vehicle state or vehicle-free state of the lane in each direction, and a control signal is output to control the traffic lights to do corresponding changes. By adoption of the scheme, the waiting time of the vehicles can be greatly shortened, and the passing efficiency of the vehicles can be improved, sothat urban and national provincial road congestion can be reduced, and vehicle pollution emission can be lowered.

Description

technical field [0001] The invention relates to the technical field of urban traffic management, in particular to a traffic light optimization scheduling method and system. Background technique [0002] In recent years, with the rapid development of the automobile industry, the number of motor vehicles has increased significantly. According to the data recently released by the Traffic Management Bureau of the Ministry of Public Security, as of the end of June 2018, the number of motor vehicles in the country reached 319 million. Among them, the number of newly registered motor vehicles in the first half of 2018 reached 16.36 million. Urban vehicle congestion is becoming more and more serious, and traffic jams in many cities are serious. [0003] In urban congestion, poor traffic scheduling is an important reason. Due to the unscientific setting time of the traffic lights in each direction, there is often a phenomenon that there is a green light in one direction but no traf...
