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

Embodiment 1
[0042] The present embodiment provides a kind of two-way green wave control method on the arterial road that can ensure the safety of bicycles, such as figure 1 shown, including the following steps:
[0043] S1: Use video tracking technology to continuously track vehicles and bicycles on the main road and branch roads in real time.
[0044] S2: Judging whether it is the starting point of the signal cycle, if so, go to step S3, otherwise go to step S6.
[0045] S3: Judging whether the number of vehicles on the branch road at the intersection is less than or equal to the switching threshold Q, if so, go to step S4, otherwise go to step S5; here, it is judged for each intersection, as long as there is a number of vehicles on the branch road at the intersection If it is less than or equal to the switching threshold, the signal lights at the intersection are controlled to enter the two-way green wave mode of the trunk line. The main purpose of this judgment is to ensure that the ...
Embodiment 2
[0059] This embodiment provides a two-way green wave control system for main roads that can ensure the safety of bicycles, including a signal control unit for controlling the color change of signal lights, and also includes:
[0060] The video tracking detection unit is distributed and arranged on the main road and the branch road, and is used for real-time and continuous tracking of vehicles and bicycles on the main road and the branch road.
[0061] The first judging unit judges whether it is the starting point of the signal period.
[0062] The second judging unit further judges whether the number of vehicles on the branch road at the intersection is less than or equal to the switching threshold Q when the judging result of the first judging unit is yes.
[0063] The signal control unit, when the judgment result of the second judging unit is yes, controls the signal light at the corresponding intersection to enter the trunk line two-way green wave mode; when the judgment re...

Abstract
The main road two-way green wave control method and system capable of ensuring the safety of bicycles described in the present invention adopts a video tracking detection unit to continuously track vehicles and bicycles on the main road and branch roads. When it is detected that there are motor vehicles or bicycles on the branch road When passing through the intersection, immediately judge whether there is a car on the main road passing the intersection. If there is a car passing through the intersection on the main road, and its position has reached the monitoring position, let the main road vehicle pass through first. If there is no car passing on the main road At the intersection, or if the monitoring position is not reached, change the color of the signal light, let the branch road be green and let the branch vehicles or bicycles pass through the intersection. That is to say, it can ensure that vehicles can safely pass through the intersection without slowing down, realize the two-way green wave traffic of the main road in the true sense, and ensure that bicycles on the branch line can pass through the intersection safely.
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...
