As a major transportation province, Guangdong plays an important role in my country's modern transportation construction. At present, the mileage of highways in Guangdong Province has exceeded 11,200 kilometers, ranking first in the country for 9 consecutive years, and the density of expressways in the Greater Bay Area ranks among the top in the global bay area. The huge expressway network, huge traffic flow, and frequent extreme disasters such as typhoons and rainstorms in recent years have brought great pressure to the smooth flow and safety of expressways. At the same time, the deep integration of new technologies such as big data and artificial intelligence with the transportation industry has made Guangdong expressways smoother and safer.
On July 21, Guangdong Communications Group and Baidu jointly released the "High-precision Digital Base Map" and "Baidu Map Guangdong High-speed Version". The high-precision digital base map released this time is the first provincial-level high-precision map "digital base" for over 10,000 kilometers of expressways in the country. It can provide unified map and data service capabilities for expressway construction, management, maintenance, operation, and service, and improve expressway operation and management efficiency. The "Baidu Map Guangdong Expressway Edition" released at the same time will bring more personalized and high-quality route planning, driving navigation, road condition awareness, and traffic incident reminders to car owners in Guangdong Province .
Liu Xiaohua, general manager of Guangdong Communications Group, Cao Xiaofeng, deputy general manager, Shi Qinghua, vice president of Baidu and general manager of the Intelligent Transportation Division, attended the event.
Cao Xiaofeng, Deputy General Manager of Guangdong Communications Group :
The product release of "High-precision Digital Base Map" and "Baidu Map Guangdong High-speed Edition" is not only an important step taken by Guangdong Communications Group in "digital transformation", but also an important new information infrastructure for future smart high-speed construction. More importantly, it can provide high-quality smart travel services for car owners.
Shi Qinghua , vice president of Baidu and general manager of the Intelligent Transportation Division :
Based on the advantages of artificial intelligence technology and open ecology accumulated over the years, Baidu will join hands with all parties in the industry to build a smart high-speed format that is safe, efficient, intelligently interactive, closed-loop inclusive, and sustainable development, making travel safe, efficient, economical, and green.
The digital twin highway system in Guangdong Province was initially completed
Realize the core scenario "management on the business map"
"High-precision digital base map" is a platform based on high-precision map data combined with industry data to provide basic support for high-quality travel services for car owners. By creating a map base of "high-precision map + high-quality industry data + unified map service entrance", the digital twin road system of Guangdong Province has been initially established. The mileage of the high-precision map in the "high-precision digital base map" has exceeded 11,200 kilometers, the three-dimensional high-precision digital assets have exceeded one million, and the highest modeling accuracy is better than 3 cm. It is a new benchmark for national highway digital bases.
"High-precision digital base map" digital twin map engine
In the future, the "high-precision digital base map" will provide basic support and innovation empowerment for expressway construction, maintenance, transportation and services. Core application scenarios such as road network operation and emergency command and dispatch, road network equipment management and maintenance, road facility maintenance and emergency response, road network vehicle owner travel services, and integrated presentation of road facilities and equipment can improve the safety and efficiency of traffic operations in an all-round way. Based on this, Guangdong Communications Group will truly realize "explaining on the problem map, seeing on the asset map, doing on the plan map, and managing on the business map".
>>In terms of emergency command and rescue , the staff of the monitoring center can monitor the high-precision map and digital twin function on the large screen to see the status of vehicles driving in each lane and the congestion status of the road network. Once emergencies such as traffic accidents, abnormal parking, and pedestrians breaking into the expressway occur, the monitoring center will receive system alerts. At this time, the staff will immediately report the incident to the highway administration, traffic police, rescue and other departments for disposal, effectively preventing accidents or further escalation of the situation.
High-precision digital base map platform-emergency rescue scene
>>In terms of road asset management , the "high-precision digital base map" manages road infrastructure, traffic safety facilities, management service facilities, emergency facilities, electromechanical facilities, etc., and accurately presents the location of each facility on a high-precision map. Operation and maintenance personnel can quickly find the specific location of facilities and equipment on the high-precision map, and understand the basic information and operating status of equipment and facilities through the digital twin function, so as to realize the refined management of road assets, as well as rapid inspection and remote operation and maintenance of equipment.
>>In terms of road maintenance management , combined with the AI lightweight inspection kit, automatic inspection of road diseases and traffic safety facility damage can be realized in daily road maintenance work, and the precise location, disease type, damage range and stake number location of road disease and traffic safety facility damage can be visualized on the high-precision map. .

At the same time, the "high-precision digital base map" has accumulated a large amount of data assets for Guangdong Communications Group. In the future, usable data resources can be formed through data governance, enabling the group's data asset management, data asset compliance registration, and data assetization.
Baidu map Guangdong high-speed version released
Provide a more refined and localized navigation experience
Based on the high-speed digital twin map created by the high-precision digital base map project, Baidu Maps launched the Guangdong High-speed version of Baidu Maps, which can provide driving users with a lane-level three-dimensional immersive navigation experience, and help users smooth out blind spots in scenes such as tall buildings and under bridges.
Relying on the business data, systems and high-precision digital base map data of Guangdong Communications Group, users can experience services such as lane-level navigation and over-the-horizon event warning during high-speed driving navigation, and can pass safely even in rainy and foggy days;
Yan Sunrong, General Manager of Baidu Digital Twin Map, said that the provincial-level digital twin map with a scale of over 10,000 kilometers released by Baidu and Guangdong Communications Group will truly "live" data and further create a more realistic, real-time, and smarter navigation experience for users.
Under the background of the national strategy of "accelerating the construction of a powerful country in transportation", the "high-precision digital base map" is expected to become a new force driving the high-quality development of Guangdong's transportation. The next ten years will be the "golden decade" for the development of smart transportation, which requires innovation and integration from all walks of life to empower Guangdong transportation with digital and extend the better life of car owners.
