[0022] In order to solve the problem in the prior art that the computing equipment and sensing equipment at the traffic monitoring point are not installed and monitored more completely, resulting in inaccurate data collection at the traffic monitoring point, please refer to Figure 1 and Figure 2 , this embodiment provides the following technical solutions: The digital traffic law enforcement insight engine and analysis platform based on edge computing includes: Traffic data collection unit for: Deploy edge computing devices and sensing devices at traffic monitoring points.

According to the analyzed degree of abnormality, an early warning will be issued at the traffic law enforcement terminal. Finally, the predicted abnormal events and the degree of abnormality of the abnormal events will be marked as traffic abnormality data.
[0023] Specifically, the edge computing device of the traffic data collection unit can quickly analyze and respond to traffic data, which helps to realize instant traffic management decisions and law enforcement actions, and improves the response speed and safety of the traffic system. The edge computing device of the data fusion analysis unit can process the input real-time data stream in real time, reducing the delay and bandwidth requirements of data transmission.

At the same time, the radar device and the camera device are used in conjunction with each other; When the sensing device collects data from the traffic monitoring points, each sensing device is first tested, and data collection is performed after all the devices are qualified. The traffic monitoring points include highway overload detection stations, dynamic monitoring points, expressway toll stations, freight sources, provincial boundary non-stop gantries, ferry crossings, comprehensive law enforcement workstations, etc. The signal equipment collects data on signal phase, signal timing and traffic violations; the camera equipment collects data on vehicle images, vehicle video streams, vehicle trajectories, traffic flow and average speed; the radar equipment collects data on vehicle speed, vehicle spacing and vehicle position; After all the data are collected, the traffic data to be analyzed are obtained.
[0025] Specifically, by deploying edge computing devices near traffic monitoring points, data from sensing devices can be processed in real time or near real time, reducing the time and bandwidth required for data transmission to remote data centers, thereby improving data processing efficiency. Edge computing devices can quickly analyze and respond to traffic data, which helps to achieve instant traffic management decisions and law enforcement actions, and improve the response speed and security of the transportation system. Data is initially processed and analyzed at the edge level, which reduces the transmission volume of sensitive data, reduces the risk of data leakage, and enhances data security. Edge computing devices can dynamically allocate computing resources according to actual needs, avoid excessive concentration and waste of resources, and improve resource utilization efficiency. The precise deployment and coordinated use of sensing equipment (such as signal machines, cameras, and radars) can achieve comprehensive and high-precision data collection of traffic monitoring points, providing a reliable data basis for traffic law enforcement and analysis. By collecting and analyzing traffic data in real time, traffic congestion, violations, and other problems can be discovered in a timely manner, and corresponding measures can be taken to intervene and manage, thereby improving the operating efficiency and safety of the transportation system.
[0026] In order to solve the problem that the existing technology does not effectively predict and process abnormal events based on the real-time data of traffic monitoring points, which leads to reduced abnormal event processing effect, please refer to Figure 1 and Figure 2 , this embodiment provides the following technical solutions: Specifically, the radar device is used in conjunction with the camera device, including: The radar device collects vehicle speed in real time; When the vehicle speed exceeds a preset first vehicle speed threshold, the camera is triggered to collect vehicle tracking video streams for the vehicle; When the vehicle speed does not exceed a preset first vehicle speed threshold, but exceeds a preset second vehicle speed threshold, a vehicle corresponding to the vehicle whose speed exceeds the preset second vehicle speed threshold is taken as a target vehicle, and the target vehicle is marked; Retrieving the vehicle driving parameters of the target vehicle obtained by the radar equipment at each traffic monitoring point previously passed by the target vehicle, wherein the vehicle driving parameters include the vehicle speed of the target vehicle, the vehicle distance between the target vehicle and the rear vehicle, the vehicle distance between the target vehicle and the front vehicle, and the vehicle speeds of the rear vehicle and the front vehicle; Using the vehicle driving parameters of the target vehicle at each traffic monitoring point, obtaining a first vehicle driving safety factor of the target vehicle at each traffic monitoring point; The first vehicle driving safety factor of the target vehicle at each traffic monitoring point is obtained by the following formula: ; Among them, S 01 represents the first vehicle driving safety factor of the target vehicle at each traffic monitoring point; D x and D h V represents the vehicle distance between the target vehicle and the preceding vehicle and the vehicle distance between the target vehicle and the following vehicle respectively; x and V h are the vehicle speeds of the front vehicle and the rear vehicle respectively; V d Indicates the vehicle speed of the target vehicle; D a Indicates the preset distance reference value; V c represents a preset vehicle speed reference value; A represents a reference constant, and the value range of the reference constant is 1.5-100; Comparing the first vehicle driving safety factor of each traffic monitoring point with a preset safety factor threshold; When the first vehicle driving safety factor of the target vehicle at any traffic monitoring point is lower than a preset safety factor threshold, the camera is triggered to collect vehicle tracking video streams for the target vehicle; When the first vehicle driving safety factor of the target vehicle at each traffic monitoring point is not lower than the preset safety factor threshold, the safety of the target vehicle is continuously judged, and when the safety of the target vehicle is lower than the safety requirement, the camera is triggered to perform vehicle tracking video stream acquisition on the target vehicle.
[0027] The technical effect of the above technical solution is: by collecting vehicle speed in real time through radar equipment, it can respond quickly to changes in traffic conditions. When the vehicle speed exceeds the preset threshold, the camera can immediately trigger the vehicle tracking video stream acquisition, which helps to capture and deal with potential dangerous situations in a timely manner. By using the collaborative work of radar and camera, speeding vehicles can be accurately identified and located, and target vehicles with speeds between two thresholds can be marked. This helps traffic management departments to classify and manage vehicles more carefully and improve law enforcement efficiency and accuracy. By retrieving the driving parameters of the target vehicle at different traffic monitoring points, including speed, vehicle spacing, etc., the driving safety of the vehicle can be comprehensively evaluated. Using these parameters to calculate the first vehicle driving safety factor at each traffic monitoring point can more objectively reflect the driving status and safety performance of the vehicle. When the first vehicle driving safety factor at any traffic monitoring point is lower than the preset safety factor threshold, the camera will automatically trigger the vehicle tracking video stream acquisition, which helps to timely discover and deal with potential safety hazards. Even if the safety factor is not lower than the threshold, the system will continue to judge the safety of the target vehicle and trigger an early warning when the safety is lower than the requirement, which reflects the intelligence and foresight of the system. Through the automated monitoring and early warning system, the subjectivity of manual intervention and judgment can be reduced, and the objectivity and fairness of traffic management can be improved. At the same time, the real-time and response speed of the system also help traffic management departments to respond to emergencies such as traffic congestion and accidents more quickly, and improve the overall traffic operation efficiency. By real-time monitoring and analyzing the driving status of vehicles, the system can promptly detect and correct the driver's violations, such as speeding and not maintaining a safe distance, thereby effectively reducing the occurrence of traffic accidents.
[0028] In summary, the technical effects of this technical solution in terms of performance indicators are mainly reflected in real-time and response speed, accurate identification and positioning, multi-dimensional data analysis, intelligent warning and intervention, improved traffic management efficiency and enhanced road safety. These effects jointly improve the efficiency and accuracy of traffic monitoring and vehicle safety management, and provide strong support for building a safer and more efficient traffic environment.
[0029] Specifically, when the first vehicle driving safety factor of the target vehicle at each traffic monitoring point is not lower than the preset safety factor threshold, the safety of the target vehicle is continuously determined, and when the safety of the target vehicle is lower than the safety requirement, the camera is triggered to perform vehicle tracking video stream acquisition on the target vehicle, including: When the first vehicle driving safety factor of the target vehicle at each traffic monitoring point is not lower than a preset safety factor threshold, extracting the first vehicle driving safety factor of the target vehicle at each traffic monitoring point; Obtaining a comprehensive vehicle driving safety factor using the first vehicle driving safety factor of the target vehicle at each traffic monitoring point; Extracting vehicle travel parameters of each subsequent traffic monitoring point after the vehicle speed of the target vehicle exceeds a preset second vehicle speed threshold, wherein the vehicle travel parameters include the vehicle speed of the target vehicle, the vehicle distance between the target vehicle and a rear vehicle, the vehicle distance between the target vehicle and a front vehicle, and the vehicle speeds of the rear vehicle and the front vehicle; Obtaining a second vehicle driving safety factor corresponding to the target vehicle at each subsequent traffic monitoring point by using the vehicle driving parameter of each subsequent traffic monitoring point after the vehicle speed of the target vehicle exceeds a preset second vehicle speed threshold; The second vehicle driving safety factor corresponding to each subsequent traffic monitoring point of the target vehicle is obtained by the following formula: ; Among them, S 02 represents the second vehicle driving safety factor corresponding to each subsequent traffic monitoring point of the target vehicle; D mx and D mh V respectively represent the vehicle distance between the target vehicle and the preceding vehicle and the vehicle distance between the target vehicle and the following vehicle corresponding to each subsequent traffic monitoring point; V mx and V mh Respectively represent the vehicle speed of the preceding vehicle and the vehicle speed of the following vehicle corresponding to the target vehicle corresponding to each subsequent traffic monitoring point; V d Indicates the vehicle speed of the target vehicle; D a represents a preset distance reference value; A represents a reference constant, and the value range of the reference constant is 1.5-100; using the comprehensive vehicle driving safety factor to compare with a second vehicle driving safety factor corresponding to the target vehicle at each subsequent traffic monitoring point; When the second vehicle driving safety factor corresponding to the target vehicle at each subsequent traffic monitoring point is lower than the comprehensive vehicle driving safety factor, the camera is triggered to perform vehicle tracking video stream acquisition on the target vehicle.
[0030] The technical effect of the above technical solution is: by extracting the first vehicle driving safety factor of the target vehicle at each traffic monitoring point and calculating the comprehensive vehicle driving safety factor, the overall driving safety of the target vehicle can be more comprehensively evaluated. By using the vehicle driving parameters of each subsequent traffic monitoring point after the target vehicle exceeds the second vehicle speed threshold, the second vehicle driving safety factor is calculated, which can accurately capture the changes in the driving state of the target vehicle and improve the accuracy and timeliness of the judgment. When the second vehicle driving safety factor is lower than the comprehensive vehicle driving safety factor, the system can immediately trigger the camera to perform vehicle tracking video stream acquisition on the target vehicle. This setting enables the system to issue an early warning in time when the driving safety of the target vehicle shows a downward trend, providing the traffic management department with a timely intervention opportunity to reduce potential safety risks. When the first vehicle driving safety factor of each traffic monitoring point is not lower than the preset safety factor threshold, the system will not immediately trigger the camera for acquisition, but will continue to judge. This design avoids unnecessary waste of resources, so that camera resources can be used more efficiently to handle vehicles that really need attention. Through automated monitoring and judgment processes, the system can quickly identify and handle potential safety hazards and improve the efficiency and accuracy of traffic management. At the same time, the system can also provide real-time vehicle driving data and safety assessment results to traffic management departments, helping management departments make more scientific and reasonable decisions. By real-time monitoring and evaluating the driving safety of vehicles, the system can promptly detect and correct drivers' violations, such as speeding and failure to maintain a safe distance. This setting helps to improve drivers' safety awareness and the consciousness of abiding by traffic rules, thereby further enhancing road safety.
[0031] In summary, the technical effects of this technical solution in terms of performance indicators are mainly reflected in enhancing judgment accuracy, improving warning sensitivity, optimizing resource utilization, improving traffic management efficiency, and enhancing road safety. These effects have jointly improved the intelligent level of traffic monitoring and vehicle safety management, and provided strong support for building a safer and more efficient traffic environment.
[0032] Specifically, using the first vehicle driving safety factor of the target vehicle at each traffic monitoring point to obtain a comprehensive vehicle driving safety factor includes: Extract the vehicle flow and vehicle speed corresponding to each unit time of each traffic monitoring point; wherein the value range of the unit time is 10s-30s; Obtain a weight value corresponding to each traffic monitoring point using the vehicle flow and vehicle speed corresponding to each unit time corresponding to each traffic monitoring point; The weight value corresponding to each traffic monitoring point is obtained by the following formula: ; Among them, W j represents the weight value corresponding to the jth traffic monitoring point; n represents the number of vehicles running per unit time at each traffic monitoring point; C i V represents the traffic volume per i-th unit time corresponding to each traffic monitoring point; i represents the average vehicle speed per unit time corresponding to each traffic monitoring point; T i represents the traffic light control response delay rate of the i-th unit time corresponding to each traffic monitoring point; Obtaining a comprehensive vehicle driving safety factor by using the weight value corresponding to each traffic monitoring point and the first vehicle driving safety factor corresponding to each traffic monitoring point; The comprehensive vehicle driving safety factor is obtained by the following formula: ; Among them, S c represents the comprehensive vehicle driving safety factor; m represents the number of traffic monitoring points; W j represents the weight value corresponding to the jth traffic monitoring point; C pj represents the average traffic flow corresponding to the jth traffic monitoring point; S 01j Represents the first vehicle driving safety factor corresponding to the j-th traffic monitoring point.
[0033] The technical effect of the above technical solution is: by considering the traffic volume and vehicle speed of each traffic monitoring point in different unit time, the technical solution can more comprehensively evaluate the driving safety of the target vehicle under different traffic conditions. The introduction of the traffic light control response delay rate as a factor in the weight calculation further improves the accuracy and practicality of the evaluation. The weight value of each traffic monitoring point is calculated by a formula to ensure the objectivity and scientificity of the weight distribution. The introduction of the weight value enables different traffic monitoring points to obtain different weights according to their importance in the calculation of the comprehensive vehicle driving safety factor, which improves the accuracy and pertinence of the evaluation. By combining the weight value of each traffic monitoring point and the first vehicle driving safety factor, the comprehensive vehicle driving safety factor is calculated, which can more accurately reflect the driving safety of the target vehicle at different traffic monitoring points. This comprehensive evaluation method helps the traffic management department to have a more comprehensive understanding of the driving status of the target vehicle, so as to make more scientific decisions.
