Control method of traffic signal lamp and system

Abstract

The invention discloses a control method of a traffic signal lamp. The traffic signal lamp is used for providing the control of passing instruction time aiming at all passing directions of junctions. The method comprises the following steps of: collecting video images of junctions, wherein the video images at least comprise video images in the target passing direction; identifying area characteristic information in the target passing direction from the video images; and calculating passing instruction time of the traffic signal lamp corresponding to the target passing direction according to the area characteristic information. The invention can dynamically adapt to the change of traffic flow of all periods of time in all directions of each junction in real time, thus improving passing efficiency of roads.

Description

technical field [0001] The invention relates to the field of signal control, in particular to a control method of traffic signal lamps and a control system of traffic signal lamps. Background technique [0002] Traffic signal lights are an important guarantee for maintaining traffic order, ensuring traffic safety and smooth flow. They are suitable for intersections such as crosses and T-shaped intersections. They are controlled by traffic signal light control devices to guide vehicles and pedestrians to pass safely and orderly. In the prior art, the control device of the traffic signal light generally adopts a single-chip microcomputer control system (such as PLC) to process relatively simple timing control logic. [0003] Specifically, intersections usually need to be provided with a plurality of traffic lights, for example, at a common intersection, it is necessary to set up north-south direction traffic lights (straight lights), east-west direction traffic lights (straigh...

Problems solved by technology

Although this implementation can reduce the waste of some road resources, it still cannot adapt well to the changes in traffic flow in each direction at each intersection and at each time period.
