Traffic signal lamp green wave intelligent adjustment method and intelligent adjustment system

Abstract

The invention relates to a traffic signal lamp green wave intelligent adjusting method and an intelligent adjusting system. Communication connection with a traffic signal lamp system is established through a first communication module, the first communication module receives operation data of an intersection traffic signal lamp and then sends the operation data to a first processor, and the firstprocessor sends the operation data of the traffic signal lamp to a storage module for storage; a speed measuring module is used for measuring the speed of a vehicle in real time and sending vehicle speed information and time information to the first processor; a camera module identifies the license plate number of the vehicle and sends license plate number information to the first processor; afterthe first processor receives the vehicle speed, the moment and the license plate number information, the data are packaged and sent to a second processor, the second processor performs speed prediction and flow analysis according to the received data, and an intersection passing result in the traffic light state period is decided according to a flow analysis result. The green wave speed per hourcan be adjusted in real time, and the passing efficiency is maximized.

Description

technical field [0001] The application belongs to the field of computer and intelligence, and in particular relates to a green-wave intelligent regulation system for traffic lights and a method for using the same. Background technique [0002] "Green wave" traffic is to install a set of automatic control linkage signals with a certain period at a series of intersections, so that when the traffic on the main road arrives at each intersection in front in turn, it will encounter a green light. This "green wave" traffic reduces the stoppage of vehicles at intersections and increases the average speed and traffic capacity. Reasonable green wave traffic is of great significance for significantly improving road traffic efficiency and alleviating traffic congestion. At the same time, efficient traffic has a significant effect on energy saving and emission reduction. [0003] The technical solution for green wave traffic in the prior art is to set a section of green wave belt, and c...

Problems solved by technology

However, the defects in the existing technology are: only a unified green wave speed can be given, but when the vehicles are slowing down at the peak of traffic, they generally cannot reach the guided green wave speed, which makes the green wave traffic invalid and causes some vehicles to The red light all the way to the end seriously affects traffic efficiency and increases emissions
