Artery two-way green wave signal control method and system capable of ensuring safety of bicycles

Abstract

The invention provides an artery two-way green wave signal control method and system capable of ensuring safety of bicycles. A video tracking and detection unit is used for continuously tracking vehicles and bicycles on an artery and a minor road, under the situation that a motor vehicle or a bicycle on the minor road is about to pass through an intersection, whether a vehicle about to pass through the intersection exists on the artery or not is immediately judged, and if a vehicle about to pass through the intersection exists on the artery and the vehicle has already reached a monitoring position, the vehicle on the artery is let to pass through the intersection preferentially; if no vehicle about to pass through the intersection exists on the artery or a vehicle has not reached the monitoring position yet, the colors of signal lamps are changed, green is displayed on the signal lamp on the minor road so that the vehicles or bicycles on the minor road can pass through the intersection, and after the vehicles or bicycles on the minor road pass through the intersection, the color of the signal lamp on the artery is changed into green. Therefore, when there is a vehicle on the artery which is about to pass through the intersection, it can be ensured that the vehicle can safely pass through the intersection without reducing the speed, two-way green wave passage on the artery and the minor road is realized in deed, and it is ensured that the bicycles on the minor road safely pass through the intersection.

Description

technical field [0001] The invention relates to the field of intelligent traffic control, in particular to a bidirectional green wave signal control method and system for an arterial road that can ensure the safety of bicycles. Background technique [0002] Regulating the traffic order at intersections, preventing and reducing traffic accidents caused by disordered intersections, and improving the efficiency of intersection traffic have become issues of concern to traffic management departments. The signal control system 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 possible at night or when the flow of branch roads is small. Two-way green waves on main roads, that is, vehicles passing in both directions on main roads can achieve green lights through...

AI Technical Summary

Problems solved by technology

[0004] The present invention solves the problem that in the prior art, when the vehicles on the trunk road in low-peak hours pass through multiple crossings continuously, the bicycles traveling on the branch line can safely pass through the crossings, and at the same time, the motor vehicles on the main road can not stop at the green light. Thereby providing a method and system for controlling bi-directional green wave signals on arterial roads that can ensure the safety of bicycles
