Major road bidirectional greenwave control method and system for guaranteeing pedestrians to cross street safely

Abstract

The invention discloses a major road bidirectional greenwave passage control method and a system for guaranteeing the pedestrians to cross a street safely. The method and system adopt a video tracking detecting unit for tracking vehicles on a major road and a minor road continuously. According to the method and the system, when the situation that a vehicle is about to go through a road junction on the minor road is detected, the situation that whether a vehicle on the major road is about to go through the road junction is determined immediately; when the vehicle goes through the road junction on the major road and reaches a detecting position, the vehicle on the major road takes precedence to go through, otherwise, the green light is turned on on the minor road to let the vehicle on the minor road to go through the road junction, as a result, when the vehicle on the major road goes through the road junction, the situation that the vehicle is not needed to slow down to go through the road junction safely is guaranteed, and the major road bidirectional greenwave passage is realized; besides, the method and the system can hint the pedestrians waiting for crossing the street outside a street-crossing waiting area to wait in the street-crossing waiting area for waiting for a green light signal, and hint the pedestrians lingering in the street-cross waiting area without the intention of crossing the street to leave the street-cross waiting area, avoid providing the green light signal to pedestrians without the need to cross the street, prevent the green light resource waste, and prevent reducing the road junction passage efficiency of a motor vehicle.

Description

technical field [0001] The invention relates to the field of intelligent traffic control, in particular to a control method and system for bidirectional green wave traffic on arterial roads that ensure pedestrians crossing the street safely. Background technique [0002] With the increasingly busy urban road traffic, standardizing the traffic order at intersections, preventing and reducing traffic accidents caused by disordered intersections, and improving the efficiency of intersections have become the concerns of traffic management departments. For this reason, large and medium-sized cities at home and abroad generally use The traffic signal control system with regional adaptive coordination function manages and controls the intersection. [0003] When people drive vehicles on the main road controlled by signal lights, they all hope that the green light will not stop all the way. This is impossible to achieve during peak hours or peak hours of traffic, but it should be pos...

Problems solved by technology

[0006] The present invention aims to solve the problem in the prior art that it is impossible for vehicles on main roads to pass through multiple intersections in low-peak hours, while taking into account the safety of pedestrians crossing the street and at the same time realizing a green light without stopping, so as to provide a vehicle that ensures the safety of pedestrians crossing the street Control method and system for two-way green wave traffic on arterial roads
