Research of realizing green wave band passing control based on traffic main line soft enclosing area video detection identification

Abstract

The invention belongs to a research of realizing green wave band traffic signal lights control based on urban traffic main line soft enclosing area video detection identification. Based on an existing point control and network control signal lights, passing vehicles driven into and out of soft enclosing areas are acquired, counted and analyzed in real time via counting technologies of radar, infrared, sensing, supersonic wave, etc. and technologies of vehicle license plate video identification and the like so that time proportion of a green light of a current crossing is adjusted, and the vehicles driven into the soft enclosing areas and the vehicles driven in straight lines from a former crossing green light can completely pass when the light of the current crossing turns green. The vehicles driven in the straight lines pass the current crossing when the light of the current crossing turns green, and the vehicles can also pass the next crossing with the light is green so that "all the way green" passage of bidirectional vehicle flow driven in the straight lines in main lines with the traffic signal lights is realized. Road segments between crossings are provided with the soft enclosing areas, which is firstly put forward by the invention so that waiting time of the vehicles stopping at the crossing with a red light is reduced, passing capacity of main line roads is enhanced and urban road traffic pressure is alleviated.

Description

technical field [0001] The invention belongs to a kind of research on video detection and identification of soft closed areas of urban traffic arteries to realize "green wave belt" control of traffic lights. On the basis of the existing point control and network control signal lights, the present invention effectively combines traffic engineering technology, artificial intelligence technology and automatic control technology, and realizes it through radar, infrared, induction, ultrasonic and other technologies such as counting and video recognition of vehicle license plates. Carry out real-time and effective collection, statistics, and analysis of passing vehicles entering and leaving the soft closed area, and then adjust the timing of the green light at this intersection, so that all vehicles that will enter the soft closed area and pass through during the green light at the previous intersection During the green light of this cycle, the straight vehicles pass completely, and...

AI Technical Summary

Problems solved by technology

With the continuous in-depth promotion and development of road traffic lights, the pressure on traffic has been alleviated to a certain extent, but the problem of vehicle congestion caused by traffic lights changing and waiting in many cities has become more and more prominent

In order to alleviate and solve this series of problems, many cities in our country have successively introduced the management concept and technology of "green wave belt" of traffic lights from abroad, but how to accurately calculate the timing of green lights has become a new bottleneck and difficulty
