Intelligent control method and intelligent control system for cross walk traffic lamp

Abstract

The invention discloses an intelligent control method and an intelligent control system for a cross walk traffic lamp, wherein the intelligent control method for the cross walk traffic lamp comprises steps of respectively monitoring flow data of vehicles which require passing of a cross walk and passengers through laser; making a traffic lamp display strategy according to the flow data of the vehicles which require passing of the cross walk and the passengers and current traffic lamp information; and controlling displaying of the traffic lamp according to the traffic lamp display strategy. According to the intelligent control method, red-and-green lamp switching time is automatically set according to the number of the passengers and the vehicles, thereby realizing intelligent control to the cross walk traffic lamp.

Description

technical field [0001] The invention relates to the field of electronic control, in particular to an intelligent control method and system for pedestrian crossing traffic lights. Background technique [0002] In the middle of some roads with relatively large flow of people and relatively wide road surface in the city, it is usually necessary to set up facilities for pedestrians to cross the road. Among them, the most costly and widely used is the pedestrian crossing, that is, the zebra crossing. Moreover, traffic lights are set on the crosswalk to control the passage of pedestrians and vehicles, so that the two cannot pass at the same time, so as to avoid traffic accidents. [0003] At present, there are usually two ways to control the traffic lights of pedestrian crossings: one is periodic traffic light switching, that is, red lights and green lights alternately turn on, and the duration of each light is fixed; the other is to set a delay button, After a certain period of ...

Problems solved by technology

But in real life, the flow of pedestrians and vehicles is different at different times. This fixed-length traffic light time will waste the precious time of pedestrians and vehicles, that is, when there are few people, the precious time of vehicles will be wasted. Time will affect the traffic volume of pedestrians, which may cause people to rush to run the red light and cause traffic accidents.

And the second way requires manual operation by pedestrians, so the existing traffic light devices are not intelligent.
