DETAILED DESCRIPTION

[0027] In order to make the purpose, technical scheme and effect of the present application clearer and more specific, the technical scheme in the embodiments of the present application will be described clearly and completely in combination with the drawings in the embodiments of the present application. The described embodiments are only possible technical implementations of the present application, not all possible implementations. Based on the embodiments in the present application, those skilled in the art can completely combine the embodiments of the present application to obtain other embodiments without creative work, and these embodiments are also within the scope of protection of the present application.

[0028] In the related technologies, the duration of traffic lights cannot be adjusted according to real-time road conditions, resulting in traffic congestion; fixed traffic light duration cannot adapt to the needs of different time periods and different traffic flows; it lacks flexibility and cannot effectively improve vehicle traffic efficiency.

[0029] The following describes the traffic light control method, system, traffic light device and storage medium of the embodiment of the present application with reference to the accompanying drawings. In view of the problem that the above-mentioned related technologies cannot control the changes of traffic lights according to real-time road conditions, resulting in poor traffic flow control effect, the present application provides a traffic light control method, in which the traffic conditions at the intersection are obtained by analyzing the information collected by the traffic light device, so as to adjust the signal light duration to obtain the current traffic signal, thereby achieving more intelligent and efficient traffic management, thereby reducing traffic congestion and improving vehicle traffic efficiency. As a result, the technical problem that the related technologies cannot control the changes of traffic lights according to real-time road conditions, resulting in poor traffic flow control effect, is solved.

[0030] In the embodiment of the present application, a camera is set up to observe the traffic flow in both directions of the intersection, and the long red light time is shortened and the short red light time is prolonged, thereby changing the traffic light time in real time and improving the vehicle traffic efficiency in the road conditions.

[0031] The technical solution of the present application is described in detail with specific embodiments below. The following specific embodiments can be combined with each other, and the same or similar concepts or processes may not be described in detail in some embodiments.

[0032] The traffic light control method described in the preferred embodiment of the present application is as follows: Figure 1 As shown, the traffic light control method comprises the following steps:

[0033] In step S101, monitoring information at the intersection is obtained.

[0034] In a possible implementation, the monitoring information includes the vehicle type and the driving direction. Traffic condition images in each direction of the intersection are collected; and the traffic condition images are processed to identify the vehicle type and the driving direction of the vehicle in the traffic condition images.

[0035] Specifically, camera setting and traffic flow monitoring, high-resolution cameras are installed at appropriate locations at intersections to ensure that the vehicle flow in all directions can be monitored in all directions. This is the basis for realizing intelligent traffic control, and real-time image acquisition provides accurate input for subsequent data analysis; using image processing technology, the camera captures and analyzes the traffic flow at the intersection in real time, including the number of vehicles and flow rate. This step is the core of the intelligent traffic light control system and directly determines the accuracy and effectiveness of the traffic light duration adjustment; the monitored traffic flow data is transmitted to the central processing unit in real time. The efficient and stable data transmission is an important factor in ensuring the response speed and accuracy of the system. High-speed communication protocols are usually used to ensure the real-time and reliability of the data.

[0036] In step S102, the traffic condition of the intersection is obtained according to the monitoring information.

[0037] In a possible implementation, the traffic condition includes vehicle flow and vehicle flow speed. According to the vehicle type and the driving direction, the vehicle positions of multiple vehicles in each direction at the intersection are obtained; according to the multiple vehicle positions, the vehicle flow of the vehicles passing through the intersection within a preset time is calculated, and the vehicle flow speed of the vehicles passing through the intersection within a unit time is calculated.

[0038] It should be noted that the central processing unit receives the traffic flow data from the camera and performs real-time analysis through a preset algorithm to determine the waiting length and flow rate of vehicles in each direction. The key to this step is the design of the algorithm, which needs to be able to quickly and accurately evaluate the vehicle demand in different directions.

[0039] Specifically, the camera continuously captures traffic information at the intersection, including the type, speed, direction, etc. of the vehicle, and sends the collected data to the central processing unit through a high-speed communication network for data preprocessing. During the data preprocessing process, the collected data is initially screened to eliminate erroneous or invalid data, such as non-vehicle objects; the data is classified according to information such as vehicle type and driving direction to facilitate subsequent analysis. Then, traffic flow analysis is performed to count the number of vehicles in each direction to understand the current traffic conditions; the speed of vehicles passing through the intersection is analyzed to determine whether there is congestion.

[0040] It can be understood that traffic volume mainly refers to the number of vehicles passing a certain position on the road within a certain period of time. It is an important indicator for measuring road traffic conditions; traffic speed refers to the distance that vehicles pass in a unit of time, which reflects the speed of vehicles. Traffic volume refers to the number of vehicles passing a certain position on the road within a specific period of time. It is usually used to evaluate the busyness of the road and the effectiveness of traffic facilities. Traffic speed refers to the distance that vehicles pass in a unit of time. It is used to describe the speed of vehicles. The speed is divided into two expressions: instantaneous speed and average speed. Instantaneous speed refers to the speed of the vehicle when it passes a certain point on the road, while the average speed is the average of the distance traveled by all vehicles in a specific period of time.

[0041] In step S103, the duration of the traffic light is dynamically adjusted according to the traffic conditions to obtain the current traffic signal.

[0042] In one possible implementation, based on the traffic volume and the traffic speed, the vehicle demand in multiple directions at the intersection is evaluated; based on the vehicle demand, a traffic light duration adjustment strategy is formulated; and according to the traffic light duration adjustment strategy, the signal light duration is dynamically adjusted to obtain the current traffic signal.

[0043] It should be noted that the control instructions of the central processing unit are converted into actual traffic light control signals through the decoder. The accuracy and stability of the decoder are directly related to whether the traffic light can correctly display the corresponding instructions. Traffic light adjustment execution: The traffic light adjusts the lighting state and duration according to the control signal to implement dynamic management. This step requires the support of traffic light hardware, such as the fast response and long life characteristics of LED lights to adapt to frequent switching.

[0044] In a possible implementation, the traffic light duration adjustment strategy includes one of increasing the green light time and decreasing the green light time. According to the vehicle demand, the traffic volume in the first direction and the second direction of the intersection is compared; and according to the traffic volume, whether to increase the green light time or decrease the green light time is determined.

[0045] It should be noted that the traffic light duration adjustment strategy is formulated: based on the data analysis results, the central processing unit dynamically formulates the traffic light duration adjustment strategy. This involves complex decision-making logic, such as judging which directions have heavy traffic and require longer green light time, and which directions have light traffic and can shorten the green light time.

[0046] In one possible implementation, a traffic light duration adjustment signal is generated according to a traffic light duration adjustment strategy, wherein the traffic light duration adjustment signal is a control signal of the traffic light; the lighting state and duration of the traffic light are adjusted according to the traffic light duration adjustment signal to obtain a current traffic signal.

[0047] It should be noted that real-time adjustment instruction generation: the central processing unit generates real-time adjustment instructions for the duration of traffic lights, and realizes dynamic adjustment of traffic lights through the control signal output module. This step requires high-precision clock synchronization and instruction execution mechanism to ensure the accuracy and timeliness of traffic light switching.

[0048] Specifically, demand assessment, directions with heavy traffic: identify directions with heavy traffic, which usually require longer green light times to reduce congestion; directions with light traffic: identify directions with light traffic, which can shorten the green light time because there are fewer vehicles waiting to pass. Strategy formulation, green light time adjustment: dynamically adjust the length of the green light time according to the size of the traffic flow, increase the green light time for directions with heavy traffic, and reduce the green light time for directions with light traffic; time allocation optimization: ensure that the total green light time does not exceed a specific limit to avoid the green light time in one direction being too long and causing other directions to wait too long. Decision logic, real-time: strategy formulation needs to take into account the real-time changes in traffic flow in order to quickly respond to sudden traffic conditions; flexibility: the strategy should have a certain degree of flexibility and be able to be fine-tuned according to actual conditions, such as traffic control in special events or emergencies. Strategy output, instruction generation: generate specific traffic light duration adjustment instructions based on the formulated strategy; instruction transmission: transmit the adjustment instruction to the traffic light control system to execute the duration adjustment.

[0049] Further, control signal reception, signal input: the traffic light control module receives the control signal from the central processing unit; signal decoding: decode the control signal to extract the light status and duration information. Light status adjustment, state switching: adjust the light status of the traffic light according to the requirements of the control signal, such as switching from red light to green light; duration control: control the light duration of the traffic light to ensure that the green light time in each direction matches the control strategy.

[0050] In step S104, feedback information is generated while vehicles and pedestrians are passing according to the current traffic signal.

[0051] In a possible implementation, the feedback information is a signal adjustment evaluation result. When the vehicle travels according to the current traffic signal, the adjusted vehicle flow and the adjusted vehicle flow speed of the vehicle are obtained; and the signal adjustment evaluation result is obtained according to the vehicle flow, the vehicle flow speed, the adjusted vehicle flow and the adjusted vehicle flow speed.

[0052] It should be noted that the status information of the traffic lights is fed back to the central processing unit for real-time monitoring and adjustment. The feedback mechanism is an important guarantee to ensure the continuous and stable operation of the system, which can be achieved through sensors or closed circuits.

[0053] Specifically, once a fault or abnormality is detected, the central processing unit will trigger an alarm mechanism to notify maintenance personnel to conduct inspections and repairs; for certain problems that can be solved automatically, such as adjusting the brightness, the central processing unit can automatically issue adjustment instructions. The overall performance of the traffic light system is evaluated based on feedback information, including failure rate, response time, etc. Based on the results of the performance evaluation, the control strategy and system configuration are optimized to improve efficiency and stability. The feedback mechanism is an ongoing process. The system needs to continuously collect and analyze the status information of the traffic lights to form a closed-loop control to ensure that the traffic light system can adapt to environmental changes and changes in its own state to achieve optimal operation.

[0054] In the embodiment of the present application, a camera is installed to monitor the traffic flow in all directions of the intersection in real time. The data collected by the camera provides a basis for adjusting the duration of the traffic light, which is the input link of the entire control system. The traffic flow data collected by the camera is transmitted to the central processing unit. Data transmission is a necessary step to achieve information exchange between traffic flow information and the traffic light control system. The central processing unit analyzes the data and determines the adjustment strategy of the traffic light duration. Data analysis and decision-making are the bridges connecting monitoring data and execution actions, which determine the adjustment of the traffic light duration. According to the data analysis results, the duration of the traffic light is dynamically adjusted. The duration adjustment directly responds to the data analysis results and is a key execution step to improve the traffic efficiency of vehicles. Implement the adjusted traffic light duration and update the traffic light status. The status update directly affects the driving of vehicles at the intersection and is the final output of the control scheme. Continuously monitor the traffic flow and adjust the traffic light duration according to real-time data. Continuous monitoring and adjustment ensure that the traffic light control scheme can adapt to the ever-changing traffic flow, which is the embodiment of the system's adaptive adjustment.

[0055] This application can better adapt to the needs of different time periods and different traffic flows by real-time monitoring of traffic flow and dynamically adjusting the duration of traffic lights, thereby improving the traffic efficiency of vehicles at intersections.

[0056] Next, the traffic light control system proposed according to the embodiment of the present application is described with reference to the accompanying drawings.
