Embodiment 1

[0043] This embodiment provides a control system capable of realizing two-way green wave traffic on trunk roads, such as figure 1 As shown, it includes a signal control unit for controlling the color change of the signal lamp, and also includes a video tracking detection unit, a first judging unit, a second judging unit, a third judging unit, a fourth judging unit and a fifth judging unit, wherein:

[0044] The detection units are distributed and arranged on the trunk road and branch roads, and are used for real-time and continuous tracking of each vehicle on the trunk road and branch roads.

[0045] The first judging unit judges whether it is the starting point of a signal period.

[0046] 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. Here, each intersection is judged. As long as the number of vehicles on ...

Embodiment 2

[0058] This embodiment provides a control method capable of realizing two-way green wave traffic on trunk roads, such as figure 2 shown, including the following steps:

[0059] S1: Use video tracking technology to conduct real-time continuous tracking of each vehicle on the main road and branch road.

[0060] S2: Judging whether it is the starting point of the signal cycle, if so, go to step S3, otherwise go to step S6.

[0061] S3: Determine 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.

[0062] S4: Control the signal light at the corresponding intersection to enter the two-way green wave mode of the trunk line, and then return to step S1.

[0063] S5: Control the signal light at the corresponding intersection to enter the normal switching mode, and then return to step S1.

[0064] S6: Determine whether the signal lights at each intersection are in th...

Abstract

The control system of the present invention that can realize two-way green wave traffic on main roads, when the video tracking detection unit detects that there is a car on the branch road to pass through the intersection, it immediately judges whether the video tracking and detection unit on the main road detects that there is a car on the way. To pass through the intersection, if there is a vehicle on the main road passing through the intersection, and its position has reached the monitoring position, let the main road vehicle pass through first. The road is a green light to let the branch line vehicles pass through the intersection. After the branch line vehicles pass the intersection, they will immediately turn back to the main line and turn the green light. In this way, when there are vehicles passing on the main line road, it can ensure that the vehicles can pass through the intersection safely without slowing down. In the true sense, the main line road is two-way Green wave passes.

Description

technical field [0001] The invention relates to the field of intelligent traffic control, in particular to a control system and method capable of realizing two-way green wave traffic on trunk roads. Background technique [0002] With the rapid development of social economy, urban road traffic is becoming increasingly busy. In order to standardize the traffic order at intersections, prevent and reduce traffic accidents caused by disorderly intersections, and improve the efficiency of intersection traffic, large and medium-sized cities at home and abroad generally adopt regional adaptive Traffic signal control system with coordinated functions. [0003] When people drive vehicles on the main roads controlled by signal lights, they all hope that the green lights will not stop all the way, which is impossible to achieve during peak hours or flat peak hours of traffic. However, at night or when the branch road traffic is small, it should be possible to realize the two-way green ...
