Intelligent traffic light based on signal control processing technology and signal control method

Abstract

The invention discloses an intelligent traffic light based on the signal control processing technology and a signal control method. The intelligent traffic light comprises a video detection device, an image processing module, an optimizing timing calculation module, a control module and a traffic signal display module, wherein the video detection device, the image processing module, the optimizing timing calculation module, the control module and the traffic signal display module are connected in sequence. Firstly, the video detection device shoots practical road conditions, vehicle queuing images are obtained, boundary operators are extracted through the image processing module according to the digital image processing technology, and a current vehicle queue length is worked out according to a built vehicle queue length model; then, vehicle queue length information is transmitted to a communication port of a single chip microcomputer through wireless communication, and the optimal green light duration is worked out according to the current vehicle queue length through a linear algorithm embedded in the single chip microcomputer. According to the intelligent traffic light based on the signal control processing technology and the signal control method, the traffic light changes intelligently according to traffic flow, and therefore the purposes of reducing traffic pressure, saving energy and reducing emission are achieved.

Description

technical field [0001] The invention belongs to the technical field of traffic lights, and in particular relates to an intelligent traffic light based on signal control and processing technology. The invention also relates to a signal control method using the above-mentioned intelligent traffic lights. Background technique [0002] Currently widely used traffic lights have certain deficiencies. Regardless of the peak period of traffic flow or the trough period, the working hours of most traffic lights are relatively fixed in each state, and a small number of traffic lights are simply set according to The time period is used to adjust the time control device of the indicator light, but such control is very inflexible and does not conform to the concept of "energy saving, emission reduction, and efficient development" in modern society. Since the possibility of building and expanding roads in big cities is becoming less and less limited by space, the current focus of urban tra...
