[0002] Currently, traffic flow in mountainous areas, construction access roads, narrow roads with passing vehicles, and tunnel construction is often affected by road conditions and traffic management capabilities at the construction site, resulting in frequent passing vehicles. This significantly reduces traffic efficiency and poses safety risks. Traditional traffic signal control methods typically rely on timing or sensor control, which inadequately consider the traffic needs of construction vehicles, leading to long wait times and traffic congestion.

DETAILED DESCRIPTION

[0020] The utility model aims to propose a traffic light control system for construction road intersections based on engineering vehicle identification, so as to solve the problems of difficulty in passing and meeting other vehicles, low traffic efficiency, and potential safety hazards in transportation processes on mountain roads, construction access roads, narrow intersections, and tunnel construction. The system includes: a remote control center, a first traffic light device set at the front end of the intersection at the starting position, and a second traffic light device set at the front end of the intersection at the end position; wherein the first traffic light control device and the second traffic light control device both include traffic lights, cameras, and data boxes; the data box is provided with a traffic light controller and a communication module; the traffic light control device can establish communication with the remote control center through the communication module, and the traffic light is controlled by the traffic light control device; the camera can also establish communication with the remote control center through the communication module.

[0021] Based on this system, traffic lights can be controlled based on the vehicle traffic at the starting and ending points detected by the camera, combined with preset strategies. For example, when a vehicle approaches at the starting point, the traffic light at the ending point is controlled to turn red, allowing vehicles at the ending point to wait at the meeting point. Similarly, when a vehicle approaches at the ending point, the traffic light at the starting point is controlled to turn red, allowing vehicles at the starting point to wait at the meeting point. This ensures the orderly passage of vehicles and avoids traffic congestion. If a construction vehicle is detected entering a construction section, it can be given higher priority and the green light duration can be increased through traffic light control, thus avoiding problems such as difficulty in passing or meeting other vehicles, low traffic efficiency, and potential safety hazards.

[0022] Example

[0023] The construction road traffic light control system based on engineering vehicle identification provided in this embodiment is applied to a two-way traffic construction road section. Figure 1 Construction section 1 has a starting point 2 and an end point 3. Vehicles can enter the section from starting point 2, and similarly, vehicles can enter the section from end point 3. A meeting point 4 is provided on one side of starting point 2, and a meeting point 5 is provided on one side of end point 3. Meeting points 4 and 5 extend laterally from the construction section to allow for meeting.

[0024] In this embodiment, a first traffic light device 6 is provided at the front end of the meeting point 4 at the starting position, and the first traffic light device 6 includes: a first data box 7, a first traffic light 8 and a first camera 9; a first communication module 17 and a first traffic light controller 16 are installed inside the first data box 7; the first traffic light controller 16 and the first camera 9 are electrically connected to the first communication module 17; the first traffic light 8 is electrically connected to the first traffic light controller 16.

[0025] A second traffic light device 10 is provided at the front end of the meeting point 5 at the terminal position. The second traffic light device 10 includes: a second data box 11, a second traffic light 12 and a second camera 13; a second communication module 19 and a second traffic light controller 18 are installed inside the second data box 11; the second traffic light controller 18 and the second camera 13 are electrically connected to the second communication module 19; the second traffic light 12 is electrically connected to the second traffic light controller 18.

[0026] A remote control center 15 is provided on the other side of the starting point 2 for acquiring real-time traffic data and traffic light control status, or sending remote control instructions to the traffic light control device to adjust the control of the traffic light.

[0027] Since in real scenarios, there may be a long construction section, in order to achieve signal relay, a signal repeater 14 is also set on one side of the middle position between the starting point 2 and the end point 3 of the construction section 1.

[0028] Furthermore, in a specific implementation, the first traffic light 8 and the first camera 9 are arranged relative to the direction of vehicle entry at the starting point 2 of the construction section 1; the second traffic light 12 and the second camera 13 are arranged relative to the direction of vehicle entry at the end point 3 of the construction section 1. This arrangement allows drivers of vehicles entering from the starting point 2 of the construction section 1 to observe the status of the first traffic light 8, while the first camera 9 can capture whether there are vehicles entering or exiting the starting point 2 of the construction section 1, as well as images of their license plates. Drivers of vehicles entering from the end point 3 of the construction section 1 can observe the status of the second traffic light 12, while the second camera 13 can capture whether there are vehicles entering or exiting the end point 3 of the construction section 1, as well as images of their license plates.

[0029] The working principle of the above control system is:

[0030] The first camera 9 and the second camera 13 respectively take real-time photos of the starting point 2 and the end point 3 of the construction section 1, and upload the captured images to the remote control center 15 through the first communication module 17 and the second communication module 19 respectively. The remote control center 15 issues control instructions to the first traffic light controller 16 and the second traffic light controller 18 based on the recognition of the camera images and the pre-established strategy, thereby controlling the status of the first traffic light 8 and the second traffic light 12.

[0031] In particular, this embodiment takes into account the priority of construction vehicles. An image processing algorithm is provided in the remote control center 15, which can identify the license plate number of the vehicle and thus determine the type of vehicle, that is, whether it is a concrete truck, a dump truck, an excavator or other construction vehicle. For construction vehicles, the traffic light controller will automatically adjust the on and off time of the traffic light in the corresponding direction according to the analysis results of the remote control center.

[0032] For example, through vehicle license plate recognition, when it is determined that construction vehicle A enters from the starting position 2 of construction section 1, the second traffic light 12 will light up red. After that, vehicles entering from the end position 3 of construction section 1 will have to stop and wait at the meeting point 5 at the end position 3. A longer red light time can be used to ensure that construction vehicle A can smoothly enter the construction area to work.

[0033] For another example: when the first camera 9 detects that a non-engineering vehicle B enters from the starting position 2 of the construction section 1, the second traffic light 12 will light up red, and thereafter, vehicles entering from the end position 3 of the construction section 1 will have to stop and wait at the meeting point 5 at the end position 3 until vehicle B exits from the end position 3 of the construction section 1; similarly, when the second camera 13 detects that a non-engineering vehicle C enters from the end position 3 of the construction section 1, the first traffic light 8 will light up red, and thereafter, vehicles entering from the starting position 2 of the construction section 1 will have to stop and wait at the meeting point 4 at the starting position 2 until vehicle C exits from the starting position 2 of the construction section 1.

[0034] In addition, when the first camera 9 or the second camera 13 detects that multiple vehicles are entering the construction section 1, the red light time of the second traffic light 12 or the first traffic light 8 can be extended to ensure smooth passing.

[0035] It should be noted that the solution of the present invention seeks to protect the structural composition of the vehicle traffic light control system, while the software algorithms involved in the system, such as the license plate recognition algorithm, the traffic light control strategy, etc. are all existing technologies, and the present invention does not improve them.

[0036] Although the embodiments of the present invention have been described, it will be understood by those skilled in the art that various changes, modifications, substitutions and variations may be made to these embodiments without departing from the principles and spirit of the present invention, all without departing from the scope of protection of the present invention.
