Description

Technical Field

[0001] The present invention relates to a method for quickly issuing warning events based on vehicle-road cooperative technology, and belongs to the technical field of information dissemination. Background Art

[0002] With the continuous advancement of the Intelligent Transportation System (ITS), Vehicle-to-Everything (V2X) technology is becoming an important part of the intelligent transportation field. V2X technology significantly improves road safety, traffic efficiency and driving experience through information exchange and collaboration between vehicles (V2V), vehicles and infrastructure (V2I), vehicles and pedestrians (V2P), and vehicles and networks (V2N). In this context, the development of a vehicle-to-road collaborative event release navigation system has become the key to improving traffic management.

[0003] Vehicle-road collaboration technology can perceive vehicle and road environment information in real time, and combine this information with road infrastructure data to provide accurate road event warnings and route optimization suggestions. By integrating the vehicle-road collaboration function into the navigation software platform through a customized data interface, real-time data can be more effectively converted into useful navigation services. This method uses the high-precision positioning function provided by the domestic Beidou satellite navigation system, combined with high-definition road rendering technology, to restore the real road scene to the maximum extent, thereby realizing lane-level precision services in navigation applications. This system can significantly improve the shortcomings of existing navigation systems in event warning and response, and improve the real-time and accuracy of information.

[0004] At present, traditional navigation systems face many challenges when dealing with unexpected events such as fires and explosions that disrupt surrounding traffic, or sudden traffic accidents such as landslides causing highway collapses, such as single data sources, delayed information updates, and slow warning responses. The process from data collection to processing and then to release takes a long time. Especially in emergencies, real-time is crucial. Delays may cause drivers to fail to understand the danger in time. Once an emergency occurs, the information transmission and approval mechanism is often cumbersome, resulting in the inability to quickly convey warning information to all affected drivers. Existing systems often rely on external traffic data sources, such as sensor data, GPS data, navigation application data, social media reports, weather forecasts, and public transportation data. These data sources have delays in the collection, transmission, and processing process, resulting in the inability to update warning information in time, affecting the driver's grasp of road conditions. In addition, the complex road environment, long information transmission chain, and strict information verification have further weakened the ability to quickly warn of road traffic emergencies. If signs of road collapse can be discovered and reported in a timely manner, rapid warnings and safe navigation routes can be issued, such accidents can be effectively avoided.

BRIEF DESCRIPTION OF THE DRAWINGS

[0017] In order to more clearly illustrate the technical solution of the present application, the drawings required for use in the embodiments are briefly introduced below. Obviously, for ordinary technicians in this field, other drawings can be obtained based on these drawings without any creative work.

[0018] Figure 1 It is the principle block diagram of the traditional traffic incident warning release mechanism; Figure 2 It is a principle block diagram of some embodiments of the present application; Figure 3 It is an interactive architecture diagram in some embodiments of the present application. DETAILED DESCRIPTION

[0019] In the existing intelligent transportation system, vehicle-road cooperative technology realizes the sharing and processing of traffic information through real-time communication between roadside facilities (such as RSU, LiDAR, millimeter-wave radar, cameras, etc.) and vehicles. However, in special scenarios such as double-deck super-large bridges, the information collected by the upper and lower roadside facilities may interfere with each other, resulting in misjudgment of information or reduced transmission efficiency. In particular, the information collected by the upper roadside facilities may be mistakenly transmitted to the lower vehicles, causing unnecessary confusion and safety hazards.

[0020] Figure 1 It is a traditional traffic incident warning release mechanism. When a traffic accident or natural disaster causes road danger, the process of synchronizing information to the navigation software usually includes the following steps: 1. The occurrence of an accident or disaster. When a traffic accident or natural disaster occurs, there will usually be witnesses, drivers or road maintenance personnel who will report the relevant situation in the first time.

[0021] 2. On-site processing and information collection. Relevant departments (such as traffic police, traffic management center, and emergency rescue department) will rush to the scene to handle the situation and collect detailed information about the accident or disaster, including location, scope of impact, and estimated cleanup time.

[0022] 3. Information is transmitted to the traffic management center, and the accident information will be quickly transmitted to the local traffic management center. These local traffic management centers are usually equipped with monitoring systems and data collection systems to monitor road conditions in real time.

[0023] 4. Information processing and analysis: The traffic management center will process the collected information, determine the impact of the accident on traffic flow, and determine the warning information that needs to be issued.

[0024] 5. Data is published to the navigation system. The traffic management center publishes the accident information to the navigation software supplier through various channels (such as traffic information publishing platform, API interface, etc.). This information may include: accident location, traffic flow changes, estimated travel time and recommended detour routes; 6. Navigation software updates. After receiving this information, navigation software (such as Amap, Baidu Maps, and Google Maps) will update its map data and traffic information in real time. Users can see real-time traffic conditions, traffic restrictions, road closures, and accident information in the software.

[0025] 7. User reminders and navigation adjustments: When a user uses navigation software and their driving route is affected, the software will automatically push a reminder and suggest that the user choose another route to avoid dangerous areas.

[0026] 8. Continuous monitoring and feedback. During the incident handling process, the traffic management center and navigation software will continuously monitor the road conditions and update the information when necessary to ensure that users obtain the latest traffic information.

[0027] In order to meet these challenges, the present invention proposes a rapid warning method for traffic incidents based on vehicle-road cooperative technology. By combining artificial intelligence technology and manual work, it can quickly and efficiently identify traffic incidents, and can realize real-time and accurate warning information release in navigation software, thereby effectively reducing the occurrence of traffic accidents and improving road traffic efficiency. This method not only makes up for the shortcomings of the existing system, but also promotes the development of intelligent transportation systems, so that they can better serve the needs of future traffic environments.

[0031] In an embodiment of the present application, a method for quickly releasing warning events based on vehicle-road cooperative technology includes: using vehicles and road infrastructure to obtain abnormal conditions of vehicles and roads in real time to obtain accident information; reporting the accident information to edge computing nodes; using edge computing nodes to identify abnormal conditions of accident information through computer vision technology accident information; using edge computing nodes to send abnormal conditions of accident information to the vehicle-road cooperative cloud control platform; using the vehicle-road cooperative cloud control platform to perform information fusion and analysis on abnormal conditions of accident information to obtain accurate accident information and warning information; using the user's navigation application to receive accurate accident information and warning information. The present invention improves the real-time transmission and processing efficiency of traffic accident information by customizing an open data interface in the navigation software platform and integrating vehicle-road cooperative functional services.

[0033] In an embodiment of the present application, the user vehicle information includes the location information of the user vehicle and the speed of the user vehicle.

[0034] In an embodiment of the present application, the present invention provides an electronic device, including a memory, a processor, and a computer program stored in the memory and executable on the processor, wherein the processor implements the steps of any of the above methods when executing the program.

[0035] In an embodiment of the present application, the present invention provides a computer-readable storage medium having a computer program stored thereon, and when the computer program is executed by a processor, the steps of any of the above methods are implemented.

[0036] The present invention relates to a rapid warning method based on a vehicle-road cooperative event publishing navigation system, which aims to improve the response speed and safety of vehicles when facing sudden traffic events. With the development of intelligent transportation systems, vehicle-road cooperative technology plays an important role in improving traffic efficiency and reducing accidents. Through real-time communication between vehicles and road infrastructure (such as traffic lights, cameras, roadside units, etc.), the navigation system can provide vehicles with dynamic traffic information. However, the existing navigation systems are unable to provide timely warnings and rapid responses when emergencies occur, which can easily lead to traffic congestion or secondary accidents. Therefore, the present invention proposes a rapid warning method to solve the delay problem in the prior art. The system includes multiple functional modules: Camera information capture module: responsible for capturing abnormal conditions of vehicles and roads in real time, monitoring and capturing accident information, and reporting data to the edge computing (MEC) node. Using computer vision technology, it analyzes images in real time, identifies abnormal conditions, and performs preliminary identification and processing.

[0037] Information fusion and transmission module: The data processed by the edge computing node is sent to the vehicle-road collaborative cloud control platform, where information fusion and analysis are performed to generate accurate accident information.

[0038] Navigation software control platform module: receives accident information from the cloud control platform and pushes warning information to the user's navigation system.

[0039] User vehicle warning module: The user vehicle receives warning information through the navigation application and displays accident-related information on the navigation interface.

[0040] Vehicle information reporting module: The navigation application reports the user's vehicle location information, speed and other data to the navigation software control platform for analysis and use by the vehicle-road collaborative cloud control platform.

[0041] Open data interface module: Customized data interface is implemented in the navigation software platform to facilitate the integration of vehicle-road cooperative functional services and data exchange. Figure 2 shown.

[0042] Problems and analysis of existing technologies: Information delay: There may be a delay in the process from when the accident information is captured by the camera to when it is received by the user's vehicle, which affects the timeliness of the warning. The delay in releasing events on highways combined with Internet navigation is usually more than 2-10 minutes. Figure 1In order to synchronize traffic accident information to the navigation software normally, the information synchronization needs to go through many steps, and timely warning and rapid response cannot be achieved, which can easily lead to traffic congestion or secondary accidents.

[0043] To address this problem, the present invention innovatively integrates the navigation software platform’s customized development data interface on the basis of the original vehicle-road cooperative system, and realizes the acquisition and use of vehicle-road cooperative functional services in navigation applications, and solves it in the following ways: Solution 1: The road camera information capture module captures abnormal images and uploads them to the edge computing node. By performing preliminary data processing and optimizing the data transmission path at the edge computing node, the delay in accident information processing and transmission is reduced. The processed data is transmitted to the vehicle-road collaborative cloud control platform. After analyzing the information, the developed API interface is used to directly synchronize it to the navigation software control platform for rapid release of warnings and update of navigation routes for users. The mechanism of posting first and then reviewing is adopted, allowing the content to be displayed first and then reviewed, which greatly reduces the response time and improves road traffic efficiency.

[0044] Solution 2: Administrator users set up by the vehicle-road collaborative cloud control platform and registered ordinary users, by discovering road safety problems caused by road congestion, traffic accidents, natural disasters, etc. during patrols, take photos and upload them to the vehicle-road collaborative cloud control platform. The vehicle-road collaborative cloud control platform uses data analysis algorithms to predict the potential impact of accidents on surrounding traffic and generate corresponding early warning information. Through an open API interface, the accident information, real-time road conditions and recommended detour routes are directly synchronized to major navigation software control platforms (such as Gaode, Baidu Maps, etc.) to ensure that the information is released to users in the shortest time. Users can choose to accept suggestions, and the system continues to monitor and update navigation instructions in real time. In this way, some sections of the road that cannot be captured by road cameras can also receive effective early warnings, and more complete road information, which also greatly reduces the response time and improves road traffic efficiency and driving safety.
