The high-profile super project Shenzhong Corridor will be opened to traffic at the end of the month. On June 28, Guangdong United Electronic Services Co., Ltd. (hereinafter referred to as "United Electronic Service Co., Ltd.") revealed 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, helping 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.
Accurate perception of traffic situation
As a leading data service provider in the expressway industry, United Electric Service Co., Ltd., with its "digital intelligence brain" massive big data resources and efficient data products and services, helps the Shenzhen-Zhongshan Corridor to build an intelligent management and control platform, realizes innovative functions such as real-time perception of traffic flow situation and systematization of safety emergency linkage, and promotes traffic management to move towards intelligence and efficiency.

The road network situation monitoring and perception technology of the "Digital Intelligence Brain" of the United Electric Service Company realizes the real-time perception and accurate evaluation and early warning of the traffic operation situation, and can detect abnormalities in real time, predict the traffic flow of the province's highway network, and diagnose and analyze traffic congestion.
In the traffic research and judgment of past holidays, the "Digital Intelligence Brain" of United Electronics Service has demonstrated its extraordinary prediction ability. 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.
In addition, UEG's "Digital Intelligence Brain" can also predict the traffic flow of key road sections in the next 15 minutes to 120 minutes, and accurately discover the areas where congestion is most likely to occur in the short term and the degree of congestion. "This provides strong support for the transportation authorities to formulate a plan for ensuring smooth traffic in advance and release forecast information in a timely manner."
Vehicle owners can obtain travel information such as traffic congestion, safety incidents, traffic control, meteorology, tunnel operation and service area operation through electronic information boards, radio, television and navigation software and other all-media matrices, ensuring the efficient operation of comprehensive emergency automation and bringing more convenience and peace of mind to car owners.
Vehicle rescue positioning efficiency improved by 40%
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 total length of the project is about 24 kilometers, about 30 kilometers away from the Humen Bridge in the north and about 31 kilometers away from the Hong Kong-Zhuhai-Macao Bridge in the south.
However, the complexity of this project also brings great challenges to operation management, especially in the event of an accident in the tunnel, 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, realizing real-time monitoring and accurate management of traffic flow, greatly improving the rescue efficiency and ensuring that the rescue vehicle can accurately arrive at the accident scene in the first time.
With the blessing 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, provide a strong guarantee for the life safety of car owners, and build a dream car owner to travel happily.

Provide intelligent support for regional linkage
During peak traffic flow or special circumstances, how can the Shenzhen-Zhongshan Corridor be shared and linked with other cross-river channels? How to control and cooperate with adjacent highways?
The "Digital Intelligence Brain" of United Electric Service Co., Ltd. empowers the intelligent management and control platform of the Shenzhen-Zhongshan Corridor, and provides intelligent support for the management of its complex cross-sea passage and about 1,000 kilometers of expressway 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).
Relying on cutting-edge digital technologies such as cloud computing and big data, United Telecom has established the largest provincial highway big data platform in China. On May 4 this year, United Telecom 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.
Faced with the challenge of cross-administrative region and multi-business entity collaboration, the intelligent platform can 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.
