The "super project" naturally has a "super brain", what kind of wisdom does the Shenzhen-Zhongshan Passage that will be opened to traffic have? On June 28, the reporter learned from Guangdong United Electronic Services Co., Ltd. (hereinafter referred to as "United Electronic Service Company") that the "digital intelligence brain" of United Electronic Service provides solid data and technical support for the expressway network in the Guangdong-Hong Kong-Macao Greater Bay Area, helps the intelligent management and control of the Shenzhen-Zhongshan Corridor to improve intelligence and efficiency, and will bring more convenience and peace of mind to car owners.
The positioning time of the vehicles on standby has dropped from an average of 3 minutes to more than 1 minute
In the traffic research and judgment of past holidays, the "Digital Intelligence Brain" of United Electronics Service has demonstrated extraordinary prediction capabilities. Chen Zhe, chief information officer of United Electronics, revealed that during the May Day period, the average accuracy of the system in predicting the average daily traffic flow, peak travel time and traffic flow of the province's highway network was as high as 91.58%, and the accuracy rate even reached 99.5% in some periods.

With its "digital intelligence brain", massive big data resources and efficient data products and services, United Telecom Co., Ltd. helps the Shenzhen-Zhongshan Corridor to build an intelligent management and control platform, realize innovative functions such as real-time perception of traffic flow situation and systematization of safety emergency linkage, and promote traffic management to move towards intelligence and efficiency. Combined with the road network situation monitoring and perception technology of the "Digital Intelligence Brain" of the company, the real-time perception and accurate evaluation and early warning of the traffic operation situation can be realized, and the traffic flow prediction of the province's highway network can be detected in real time, and the traffic congestion diagnosis and analysis can be carried out.
The Shenzhen-Zhongshan Corridor integrates bridges, islands, tunnels and underwater interconnection, and is one of the most difficult cross-sea cluster projects in the world. The complexity of this project poses great challenges to the operation and management, especially in the event of an accident in the tunnel, and the difficulty and urgency of safety rescue have increased significantly. In traditional rescue, it is difficult for car owners to accurately describe their location, which not only delays the rescue time, but also increases the difficulty of rescue.
Chen Zhe said that with the empowerment of the "digital intelligence brain" of United Electronic Services, the vehicle rescue service organization of the Shenzhen-Zhongshan Corridor can quickly locate the section and direction of the highway network where the vehicle is located through the license plate number, realize real-time monitoring and accurate management of traffic flow, greatly improve the rescue efficiency, and ensure that the rescue vehicle can accurately arrive at the accident scene in the first time.
With the support of the "one-click rescue" data service of United Electric Service, the positioning time of the vehicle to be assisted has been reduced from an average of 3 minutes to an average of more than 1 minute, and the efficiency has been increased by more than 40%, which can effectively reduce secondary accidents and provide a strong guarantee for the life safety of car owners.
Potential applications and landing scenarios of the digital twin of the Shenzhen-Zhongshan Channel
Provide smart support for the 1,000-kilometer expressway network of the Shenzhen-Zhongshan Corridor
During peak traffic flow or special circumstances, how can the Shenzhen-Zhongshan Corridor be shared and linked with other cross-river channels, and how can it be controlled and coordinated with adjacent expressways? This is essential for connecting multiple high-speed deep-middle corridors.
According to reports, the "Digital Intelligence Brain" empowers the intelligent management and control platform of the Shenzhen-Zhongshan Channel, providing intelligent support for the management of its complex cross-sea passage and about 1,000 kilometers of high-speed road network of 4 bridges and 15 roads connecting the two sides of the strait (including Huangpu Bridge, Nansha Bridge, Humen Bridge, etc., as well as 7 related expressways on the east bank of the Pearl River).
The Guangdong-Hong Kong-Macao Greater Bay Area backbone expressway network intelligent traffic management and control project is covered
Relying on cutting-edge digital technologies such as cloud computing and big data, United Electronic Service Company has established the largest provincial highway big data platform in China. On May 4 this year, United Electronics Service Co., Ltd. completed the real-time traffic data service of the intelligent traffic management and control platform of the backbone expressway network in the Guangdong-Hong Kong-Macao Greater Bay Area, realizing the efficient processing of about 38 million traffic data per day, accounting for 25% of the total traffic data in the province, setting a new benchmark for the intelligence and precision of regional traffic management. Relying on strong data interconnection, it has become a reality to realize the "one game of chess" management and control for the Shenzhong channel and other channels.
In the face of the challenge of cross-administrative regions and multi-business entity collaboration, the intelligent platform can also assist the management department to carry out multi-level linkage traffic control through data connectivity. With the support of digital-assisted decision-making, early warning and rapid linkage of emergency special situations can be realized.
