[0024] Existing tunnel traffic scheduling mainly relies on the planning of managers and the subjective judgment of drivers. It is difficult for managers and drivers to obtain comprehensive traffic information, and it is difficult to find the optimal allocation of traffic resources in a complex environment with a large number of vehicles, resulting in low traffic scheduling efficiency.

[0025] The tunnel traffic dispatching system proposed by the present invention is applied in a tunnel. The tunnel includes a plurality of intersections 40, each of which is equipped with a signal light 30. The tunnel traffic dispatching system includes a collection module, an identification module, a data analysis module and a dispatching module. The collection module includes a camera 10 and an RFID20 module. The RFID20 module includes an RFID20 tag and a reader. The RFID20 tag is installed on a vehicle. There are multiple cameras 10 and readers. Each intersection 40 is equipped with a camera 10 and a reader. Each camera 10 is used to collect the number of vehicles at the corresponding intersection 40 in real time, and the reader is used to collect the RFID20 tag on the vehicle; the identification module is used to identify the identity information of the vehicle according to the RFID20 tag; the data analysis module is communicatively connected to the camera 10 and the identification module, the data analysis module is used to prioritize the vehicles according to the number of vehicles and the identity information on each vehicle, and perform dispatching operations according to the priority ranking using an AI algorithm; the dispatching module is communicatively connected to the data analysis module and each signal light 30, and the dispatching module is used to control each signal light 30 according to the result of the dispatching operation.

[0026] See also Figure 1 , Figure 1Schematic diagram of an embodiment of the tunnel traffic dispatching system provided by the present invention; In the tunnel traffic dispatching system proposed by the present invention, the identification module uses RFID20 technology to quickly identify the identity of each vehicle, ensuring the accuracy of the data and the efficiency of vehicle management. The data analysis module conducts in-depth analysis of the collected data through communication connection with the camera 10 and the identification module, and uses the AI ​​algorithm to prioritize the vehicles, thereby realizing intelligent dispatching. The dispatching module communicates with each signal light 30 according to the calculation results of the data analysis module, and dynamically controls the signal light 30 to adapt to the ever-changing traffic conditions.

[0027] The tunnel traffic dispatching system proposed in the present invention collects vehicle information in the tunnel and uses AI algorithms to analyze the data, thereby dispatching the signal lights 30 and improving the traffic efficiency in the tunnel. Secondly, the system enhances the safety of the tunnel through real-time monitoring and vehicle identity recognition, and can respond quickly in emergency situations to provide priority access for rescue vehicles. In addition, the intelligent management of the system reduces manual intervention and management costs, while improving the accuracy and reliability of traffic management, which can effectively improve the efficiency and safety of tunnel traffic management.

[0028] In one embodiment, a flow meter is installed between any two intersections 40 , and the flow meter is used to collect vehicle flow in the tunnel.

[0029] It should be noted that a flow meter is installed in the middle of each tunnel. The flow meter collects the vehicle flow in the tunnel and sends the vehicle flow information to the data analysis module. The data analysis module analyzes and predicts the vehicles that will pass through each intersection 40 according to the vehicle flow in each tunnel, so as to identify the vehicle flow peak of each intersection 40 in advance, thereby controlling the traffic lights 30 to be scheduled in advance. The setting of the flow meter enables the tunnel traffic dispatching system to more accurately predict traffic trends and make scheduling adjustments of the traffic lights 30 in advance.

[0030] In one embodiment, a warning light is installed near the intersection 40 in the tunnel, and the warning light is communicatively connected to the dispatching module, and the dispatching module controls the warning light to sound an alarm according to the vehicle flow. It can be understood that the communication connection between the warning light and the dispatching module enables the tunnel traffic dispatching system to dynamically control the turning on and off of the warning light according to the real-time traffic conditions and data analysis results, and to sound an alarm through the warning light when the vehicle flow in the tunnel is too large, so as to remind the drivers in the tunnel to pay attention to driving safety.

[0031] In one embodiment, the tunnel traffic dispatching system further includes a reminder module, which is installed on the vehicle and is communicatively connected to the dispatching module. The dispatching module controls the reminder module to issue a voice broadcast reminder to the driver according to the result of the dispatching operation.

[0032] It can be understood that after the dispatch module analyzes the vehicle flow information in the tunnel, it can assist the driver through the reminder module to understand the current traffic conditions and take recommended driving behaviors, such as slowing down, avoiding or detouring. Through timely voice reminders, the driver can respond to traffic changes in the tunnel more quickly and reduce the risk of accidents.

[0033] In one embodiment, the vehicle includes a car, a special-shaped engineering vehicle, a tricycle or an electric two-wheeled vehicle. It can be understood that different RFID20 tags are installed for different types of vehicles, and different driving speeds are set according to different vehicle types in the data analysis module, customized priority sorting is performed according to the type of vehicle, and corresponding scheduling strategies are specified, so that the tunnel traffic scheduling system can adapt to and manage various types of vehicles, thereby improving the practicality and coverage of the tunnel traffic scheduling system.

[0034] The present invention also provides a tunnel traffic dispatching method, which is applied with the above-mentioned tunnel traffic dispatching system. The tunnel traffic dispatching method comprises the following steps:

[0035] S10: Install cameras and readers at intersections, and deploy recognition modules, data analysis modules, and dispatching modules in tunnels;

[0036] S20: defining the priority of vehicles;

[0037] S30: inputting the defined priority information into the scheduling module;

[0038] S40: installing RFID tags of different priorities according to the type of vehicle;

[0039] S50: sensing the number of vehicles in the tunnel and the RFID tags through a camera and a reader, and identifying the RFID tags on the vehicles through the identification module to obtain priority information of the vehicles;

[0040] S60: Performing scheduling operations on the plurality of vehicles in the tunnel through the data analysis module, and controlling each traffic light according to the results of the scheduling operations through the scheduling module.

[0041] See also Figure 2 , Figure 2 The flow chart of an embodiment of the tunnel traffic dispatching method provided by the present invention is as follows. The tunnel traffic dispatching method proposed by the present invention identifies different types of vehicles through the camera 10 and RFID 20 technology, effectively improving the accuracy of vehicle identification. The vehicles in the tunnel are intelligently dispatched through the data analysis module and the dispatching module, so that the tunnel traffic dispatching system can adjust the dispatching strategy according to real-time data, flexibly respond to changes in traffic flow, reduce the waiting time of vehicles in the tunnel, and improve the overall travel speed.

[0042] In one embodiment, step S20 includes:

[0043] S21: setting the association relationship between each vehicle and the construction process;

[0044] S22: Prioritize the vehicles according to the priorities of the different construction processes and the priorities of the different vehicles in the same construction process.

[0045] What can be explained and illustrated is that the priority order of different types of vehicles is determined according to the construction process of the tunnel construction, such as excavators, transport vehicles, engineering maintenance vehicles, etc. corresponding to the excavation, paving, maintenance and other processes, so as to give priority to the passage of vehicles in key construction processes and speed up the construction progress.

[0046] In one embodiment, step S60 includes:

[0047] S61: performing comprehensive sorting according to the distance and priority of the vehicles to the intersection;

[0048] S62: performing the scheduling operation according to the comprehensive ranking information of each of the vehicles;

[0049] S63: Control each of the traffic lights according to the result of the scheduling operation.

[0050] In one implementation, the distance for a vehicle to reach the intersection is A, the priority of the vehicle is B, and the comprehensive sorting result is C, where C=B / A.

[0051] Specifically, the traffic light 30 is dispatched by comprehensively sorting the priority of each vehicle and its distance from the traffic light 30. The comprehensive sorting result C of the vehicle is equal to the ratio of the vehicle's priority B and its distance A from the traffic light 30, and the weight of the priority is higher than the distance from the traffic light 30, thereby ensuring that high-priority vehicles can pass first, while taking into account vehicles that are closer to the traffic light 30. While ensuring that vehicles in key construction processes pass first, the waiting time of vehicles at the intersection 40 is reduced as much as possible, which helps to achieve efficient scheduling of traffic in the tunnel.

[0052] In one embodiment, after step S40, the tunnel traffic scheduling method further includes:

[0053] S41: installing a reminder module on the vehicle and connecting the reminder module to the scheduling module for communication;

[0054] S42: The scheduling module controls the reminder module to issue a voice broadcast reminder to the driver according to the result of the scheduling operation.

[0055] The above description is only an exemplary embodiment of the present invention, and does not limit the patent scope of the present invention. All equivalent structural changes made by using the contents of the present invention specification and drawings under the technical concept of the present invention, or directly / indirectly applied in other related technical fields are included in the patent protection scope of the present invention.
