[0002] The current road traffic system has many deficiencies that are not intelligent enough, which are mainly reflected in the following aspects:
[0003] First, the information perception capability is insufficient. Existing traffic systems often rely on traditional sensors and manual reports to obtain road condition information, which is not only inefficient but also easily affected by environmental and weather factors, resulting in inaccurate or delayed information. Intelligent transportation systems should be able to perceive key information such as traffic flow, vehicle speed, and congestion conditions in real time and accurately.
[0004] Secondly, data processing and analysis capabilities are limited. Even if a large amount of traffic data is collected, the existing system often lacks effective processing and analysis methods and cannot deeply explore the laws and trends behind the data. This limits the ability of traffic managers to accurately control and predict road conditions.
[0005] Furthermore, the decision support capability is insufficient. In traffic management, it is often necessary to make decisions quickly and accurately to deal with unexpected traffic conditions. However, existing systems often lack intelligent decision support functions and cannot provide effective decision suggestions based on real-time data, resulting in inefficient traffic management.
[0006] In addition, the lack of coordination in the transportation system is also a significant flaw.

[0052] It should be noted that the radar-based intelligent traffic method provided in the embodiment of the present invention is generally executed by a server / terminal device, and accordingly, the radar-based intelligent traffic device is generally arranged in the server / terminal device.
[0053] It should be understood that the number of terminal devices, networks and servers is only illustrative. Depending on the implementation requirements, there can be any number of terminal devices, networks and servers.
[0054] Embodiment 1
[0055] Please refer to Figure 1 , shows a flow chart of an embodiment of a radar-based intelligent traffic method of the present invention. The radar-based intelligent traffic method comprises the following steps:
[0056] Step S1, scanning the traffic situation in real time through radar to obtain real-time data of vehicles and pedestrians.
[0057] In this embodiment, the electronic device (e.g., server / terminal device) on which the radar-based intelligent transportation method runs can receive the radar-based intelligent transportation request through a wired connection or a wireless connection. It should be noted that the above wireless connection method may include but is not limited to 3G / 4G / 5G connection, WiFi connection, Bluetooth connection, WiMAXX connection, Zigbee connection, UWB (ultra wideband) connection, and other wireless connection methods currently known or to be developed in the future.
[0058] In this embodiment, step S1, scanning the traffic situation in real time by radar to obtain real-time data of vehicles and pedestrians, may further include the following steps:
[0059] S11, according to the application scenario, radars are set up at different locations to build a radar network.
[0060] Building a radar network involves optimizing the deployment of radar equipment at multiple locations to achieve efficient target detection, positioning, and tracking. First, the appropriate type and number of radars need to be selected according to the needs of the application scenario. For example, in areas where high-resolution detection is required, multiple high-precision radars can be deployed. Then, these radars are connected to the fusion processing center through effective communication means to form a unified and complete network system.
[0061] In the networked radar system, the fusion processing center is responsible for collecting the detection data of each local radar, and performs comprehensive processing to generate relevant intelligence information within the coverage area. Information sharing is maintained between devices, and communication between radars is also carried out through the fusion processing center. According to the intelligence obtained and the changes in the battlefield situation, the fusion processing center adaptively adjusts each local radar to make full use of the diversity advantages of radar.
[0062] S12, real-time data of vehicles and pedestrians are collected by the radar network.
[0063] Millimeter-wave radar and lidar are used to collect raw data. Millimeter-wave radar converts analog signals into digital signals through an analog-to-digital converter (ADC), and lidar obtains data by emitting lasers and receiving reflected signals. Radar emits electromagnetic waves and receives reflected signals, and obtains real-time data such as location and speed information of target objects such as vehicles and pedestrians through signal processing.
[0064] Step S2, processing and analyzing the real-time data to extract traffic flow information data.
[0065] In this embodiment, step S2, processing and analyzing the real-time data to extract traffic flow information data, may further include the following steps:
[0066] S21, cleaning the real-time data.
[0067] The collected real-time data is identified and filtered out through algorithms to remove abnormal data, noise data, etc. This ensures the accuracy and consistency of the data.
[0068] S22, deduplication is performed on the cleaned real-time data.
[0069] Real-time data deduplication after cleaning is a key step in data processing. Its main purpose is to eliminate duplicate data records in the data set, thereby retaining unique data records. This step plays an important role in improving data quality, reducing storage space usage, and improving data processing efficiency.
[0070] In practice, data deduplication can be performed in a variety of ways, such as using sets, list derivations, SQL's DISTINCT keyword or GROUP BY statement, Excel's "remove duplicate values" function, and the drop_duplicates() method in the Pandas library. These methods can be selected based on the characteristics and scale of the data to ensure deduplication efficiency and accuracy.
[0071] The role of data deduplication is mainly reflected in the following aspects: First, deduplication can avoid repeated calculations and reduce unnecessary computing overhead, thereby improving data processing speed. Second, deduplication can reduce storage space usage, making data sets more compact and easier to store and manage. In addition, deduplication can also improve data consistency and reliability, ensuring the accuracy and credibility of data analysis results.
[0072] In real-time data processing scenarios, data deduplication is particularly important. Real-time data is often time-sensitive and frequently updated. Deduplication can ensure the uniqueness of data and prevent duplicate data from interfering with analysis results. At the same time, real-time data deduplication can also improve the real-time and accuracy of data processing, providing strong support for data analysis and decision-making.
[0073] S23, converting the format of the real-time data after deduplication.
[0074] First, clarify the source and target format of the data. In actual operation, ETL (extraction, transformation, loading) tools such as Talend, Apache Nifi, etc. can be used.
[0075] The role of format conversion is mainly reflected in improving data compatibility, interoperability and processing efficiency. Different systems and applications may require different data formats. Through conversion, we can ensure the seamless flow of data between different platforms. At the same time, some data formats are more suitable for specific queries and operations. After conversion, the speed and efficiency of data processing can be significantly improved.
[0076] In addition, format conversion can also help optimize data storage efficiency and reduce storage costs. For example, converting text files to compressed binary format can significantly reduce disk space usage. In short, format conversion of real-time data after deduplication is an important means to ensure data quality and improve data processing efficiency.
[0077] S24, archiving the data after format conversion, the real-time data after archiving is the traffic flow information data.
[0078] Use a data archiving system to archive the converted data. The archiving process can include near-line archiving and offline archiving. Near-line archiving migrates data to another database table, while offline archiving backs up data as a disk file. In this process, the integrity, accuracy, and security of the data need to be ensured.
[0079] The archived data can be converted into traffic flow information data through specific processing and analysis. Through data mining, analysis and visualization, key information such as traffic flow and vehicle driving conditions can be extracted. This information is of great significance for traffic management and planning, and can be used to optimize traffic flow and improve road safety.
[0080] Step S3: analyzing the traffic status according to the traffic flow information data.
[0081] In this embodiment, step S3, analyzing the traffic status according to the traffic flow information data may further include the following steps:
[0082] S31, classifying vehicles and pedestrians according to the traffic flow information data.
[0083] During the classification process, the machine learning algorithm extracts features from the image, such as shape, size, color, etc., and then classifies the object based on these features. For example, vehicles are usually large in size and regular in shape, while pedestrians are relatively small and have variable shapes. By training a large amount of sample data, the machine learning model can gradually learn these features and achieve accurate classification of vehicles and pedestrians.
[0084] S32, count the number, density, and flow speed indicators of vehicles and pedestrians.
[0085] The classified targets are counted using counting algorithms. For vehicles, they can be counted based on information such as license plate recognition or body shape; for pedestrians, they can be counted based on information such as body outline or movement trajectory.
[0086] Time window: Set a time window to count the number of vehicles and pedestrians passing through the time window. The size of the time window can be adjusted according to actual needs.
[0087] Density refers to the number of vehicles and pedestrians per unit area or unit volume. In the traffic flow data obtained by radar scanning, density can be estimated by calculating the size of the space occupied by the target. The specific implementation methods include:
[0088] Spatial division: Divide the target area into multiple small grids or pixels and count the number of targets in each grid or pixel.
[0089] Density calculation: Calculate the density value in each grid or pixel according to the size of the grid or pixel and the number of targets. Then average or weighted average the density values of all grids or pixels to get the density value of the entire target area.
[0090] Flow speed refers to the distance vehicles and pedestrians move per unit time. In the traffic flow data obtained by radar scanning, the flow speed can be estimated by calculating the position change of the target at consecutive time points. The specific implementation methods include:
[0091] Position tracking: Use the radar's continuous scanning data to track the target's position changes at continuous time points.
[0092] Speed calculation: Calculate the target's moving speed based on the target's position change and time interval at consecutive time points. Then average or weighted average the moving speeds of all targets to get the flow speed value of the entire target area.
[0093] Step S4, formulating a traffic control strategy according to the traffic status and in combination with traffic rules.
[0094] In this embodiment, step S4, formulating a traffic control strategy according to the traffic status and in combination with traffic rules, may further include the following steps:
[0095] S41, according to the traffic status and in combination with traffic rules, formulate traffic light control rules and pedestrian and vehicle traffic rules.
[0096] Phase refers to the different release states of the traffic light in one cycle. Phase design should be determined based on the number of lanes and the proportion of turning vehicles in the traffic volume. For example, a four-phase signal control system can include states such as straight, left turn, right turn and pedestrian crossing.
[0097] The cycle time refers to the total time it takes for all phases to appear in sequence. It is determined based on traffic flow and saturation, while taking into account the loss of the green light phase. Traffic management personnel need to use traffic flow data to analyze the traffic demand of each phase and reasonably set the cycle time to achieve efficient operation of traffic flow.
[0098] The green-to-light ratio is the ratio of the green light time of each phase to the cycle time. It needs to determine the effective green light time according to the traffic volume of each phase. In actual operation, it is also necessary to consider factors such as green light loss time, green light interval time, slope, right-turn vehicle ratio, left-turn turning radius, lane width, and non-motorized vehicles, and make flexible adjustments.
[0099] In order to achieve more intelligent traffic control, traffic flow detectors can be used to obtain traffic data in real time, and algorithms can be used to dynamically adjust the cycle duration and green-to-light ratio of traffic lights to adapt to changes in real-time traffic conditions.
[0100] Set pedestrian traffic rules, such as pedestrians should walk on the sidewalk, or walk close to the roadside if there is no sidewalk, etc.
[0101] Set vehicle traffic rules, such as vehicles should follow traffic lights, etc. If the road is divided into motor vehicle lanes, non-motor vehicle lanes and sidewalks, motor vehicles, non-motor vehicles and pedestrians should each go their own way.
[0102] Traffic control strategy is the basis for setting traffic light parameters, which can include timing control, induction control and adaptive control.
[0103] Timing control: Based on historical traffic flow data, preset the green light time, red light time and yellow light time for each direction. The timing control strategy is simple and reliable, but lacks flexibility and is difficult to cope with real-time changes in traffic flow.
[0104] Inductive control: The traffic flow is detected in real time through the vehicle flow detector, and the signal light parameters are adjusted dynamically according to the traffic flow changes. The inductive control strategy can better adapt to the real-time changes in traffic flow, but it may interfere with the traffic flow of adjacent intersections.
[0105] Adaptive control: Based on real-time traffic data, traffic light parameters are adjusted in real time through advanced algorithms to achieve global optimal traffic control.
[0106] S42, dynamically adjust and optimize traffic rules and control strategies based on real-time traffic data.
[0107] Dynamic timing can be performed, and the duration of the signal light can be dynamically adjusted according to the real-time traffic flow and queue length to optimize the green wave band. For example, when the traffic flow in a certain direction is large, the green light time in that direction can be extended to reduce the waiting time of vehicles and improve the road traffic efficiency.
[0108] It is also possible to carry out multi-intersection linkage control: through green wave coordinated control, congestion linkage control and other methods, the desired control effect can be achieved at different time periods. This requires the use of real-time detected traffic data on appropriate sections to optimize the intersection cycle, green light time, and phase difference in real time, and improve the traffic efficiency of single intersections and trunk lines.
[0109] Traffic guidance can also be provided. Through electronic display screens, mobile phone applications, etc., real-time road information and optimal travel route suggestions can be provided to travelers. For example, when a road is congested, vehicles can be guided to choose other unobstructed roads in a timely manner, thereby dispersing traffic flow and alleviating congestion.
[0110] Based on real-time passenger flow data, the bus departure frequency and route planning are dynamically adjusted to improve the service level and attractiveness of buses, encourage more people to choose public transportation, thereby reducing the use of private vehicles and alleviating road traffic pressure.
[0111] Step S5: adjusting the traffic lights and traffic signs according to the traffic control strategy.
[0112] In this embodiment, step S5, the step of adjusting the traffic lights and traffic signs according to the traffic control strategy specifically includes:
[0113] S51, setting parameters of the signal light controller.
[0114] The traffic light controller controls the display time and sequence of the red, yellow and green lights of the traffic lights through a preset program, thereby guiding and controlling the traffic flow. Its basic working principle can be summarized as follows: receiving input signals (such as vehicle flow detection, pedestrian crossing requests, etc.), outputting control signals according to preset control strategies (such as timing control, induction control, adaptive control, etc.), and driving the traffic lights to display the corresponding light colors.
[0115] The parameter settings of the traffic light controller mainly include green light time, red light time, yellow light time, phase setting and cycle duration, etc.
[0116] Under the timing control strategy, the setting of signal light parameters mainly depends on historical traffic flow data. By counting the traffic flow during peak and off-peak periods in each direction, reasonable green light time, red light time and yellow light time can be preset. For example, for the intersection of main roads and branch roads, different signal light cycle durations and phase sequences can be set according to different traffic flows.
[0117] In the timing control strategy, phase setting also needs to be considered. Phase refers to the time period in which vehicles in different directions obtain the right of way in a complete cycle of signal light control. Phase setting needs to comprehensively consider factors such as vehicle volume, number of lanes, and pedestrian crossing needs to ensure smooth and safe traffic flow.
[0118] Under the induction control strategy, the setting of traffic light parameters depends on real-time traffic flow data. Traffic flow detectors detect the traffic flow in each direction in real time, and the traffic light parameters can be adjusted dynamically. For example, when a sudden increase in traffic flow in a certain direction is detected, the green light time in that direction can be extended to reduce vehicle waiting time.
[0119] The parameter setting under the induction control strategy also needs to consider the layout and sensitivity of the sensors. The layout of the sensors needs to cover the traffic flow in each direction to ensure the accuracy and integrity of the data. The sensitivity of the sensors needs to be adjusted according to the actual traffic conditions to avoid false detection and missed detection.
[0120] S52, when traffic flow changes, the traffic light timing scheme is dynamically adjusted by real-time detection of traffic data to achieve adaptive control.
[0121] Under the adaptive control strategy, the setting of traffic light parameters depends on real-time traffic data and advanced algorithms. By collecting and analyzing data such as traffic flow, vehicle speed, and vehicle type in real time, traffic light parameters can be adjusted in real time to achieve global optimal traffic control.
[0122] The parameter setting under the adaptive control strategy requires the support of the intelligent transportation system (ITS). By integrating a variety of sensors, communication equipment and control systems, ITS can collect and analyze traffic data in real time and automatically adjust the signal light parameters according to the analysis results. For example, based on the intelligent fuzzy control theory, the green light time and red light time can be adjusted in real time according to the traffic vectors in each direction to reduce vehicle waiting time and improve traffic efficiency.
[0123] S53, establish a traffic light fault monitoring and alarm system to promptly detect and handle traffic light faults and ensure the normal operation of traffic lights.
[0124] The traffic light fault monitoring and alarm system can include the following parts: front-end sensing equipment, video fusion management platform, intelligent analysis gateway, alarm push module, terminal viewing equipment, etc.
[0125] Front-end sensing equipment: mainly includes electronic police cameras and checkpoint cameras at intersections, which are used to collect video image data at traffic intersections in real time.
[0126] Video fusion management platform: The SkeyeVSS video fusion management cloud platform is used. Based on advanced technologies such as video surveillance technology, network transmission technology, GIS geographic information technology, and AI image intelligent recognition technology, the platform aggregates and manages the transmission data of all front-end sensing devices, performs intelligent analysis, processing and distribution, and pushes early warnings.
[0127] Intelligent Analysis Gateway: Based on deep learning algorithms, it conducts intelligent analysis of video images and can identify common faults such as signal lights being on at the same time, off, insufficient brightness, always on, yellow flashing, occlusion, missing display, displacement, etc., and achieve detection within seconds.
[0128] Alarm push module: When a signal light failure is detected, the system can push alarm information in real time and notify relevant personnel to go to the scene to handle it. Alarm information can be sent through SMS, email, APP push and other methods.
[0129] Terminal viewing equipment: Managers can remotely view and manage traffic lights anytime and anywhere through PC, mobile phone, tablet, WeChat, electronic large screen / TV wall, WEB H5 and other terminals.
[0130] S54, setting and managing traffic signs.
[0131] In some optional implementations of this embodiment, S54, setting and managing traffic signs further includes:
[0132] S541, set up traffic signs, including instruction signs, warning signs and prohibition signs, based on road grade, traffic volume and traffic direction.
[0133] S542, a variable electronic display screen is set on the road to provide traffic information to the driver according to the real-time traffic conditions.
[0134] S543, regularly maintain and update traffic signs to ensure their clarity and accuracy.
[0135] By reasonably setting traffic signs, we can improve traffic safety, optimize traffic order, and improve road traffic efficiency, creating a safer and more convenient travel environment for the public.
[0136] The beneficial effects of implementing this embodiment are as follows: by scanning the traffic conditions in real time through radar, the dynamic data of vehicles and pedestrians can be accurately captured, ensuring the timeliness and accuracy of traffic information; the in-depth processing and analysis of real-time data can efficiently extract traffic flow information data, providing a solid foundation for subsequent traffic status analysis; in the traffic status analysis link, the method can fully understand abnormal situations such as traffic congestion and accidents, provide decision-making support for traffic managers, and combine traffic rules to formulate traffic control strategies that are more scientific and targeted, effectively improving the efficiency of traffic diversion; according to the real-time traffic control strategy, the signal lights and traffic signs can be flexibly adjusted to achieve dynamic optimization of traffic flow, which not only significantly improves the road capacity, but also effectively alleviates urban traffic pressure and improves the overall operating efficiency of urban traffic.

For example: personal computers, server computers, handheld or portable devices, tablet devices, multiprocessor systems, microprocessor-based systems, set-top boxes, programmable consumer electronic devices, network PCs, minicomputers, mainframe computers, distributed computing environments including any of the above systems or devices, etc. The present invention can be described in the general context of computer-executable instructions executed by a computer, such as program modules.
