The era of intelligent high speed is coming. What challenges and achievements does it have?

In August 2017, the Ministry of Transport issued the overall plan of "New Generation National Control Network and Intelligent Highway." The overall goal in the plan is to realize that 80% of expressway vehicles are under the supervision of traffic control network through about 15 years of construction and improvement, and the passing capacity is increased by 3-6 times.

In the past, after several years of infrastructure construction in China, transportation will be transformed into digitalization, automation and intelligence. Smart high-speed is an important application field of the Internet of Things, and it has also been a hot topic in recent years. With the improvement of living standards, social vehicles are also increasing, especially during holidays, road congestion has become a common occurrence. How to use the Internet of Things and big data to improve traffic conditions has become a problem in front of IoT people.

Smart high-speed can be understood as a harmonious unity of people, vehicles, roads and the environment, and ultimately make traffic operation efficient, safe and green. From a professional point of view, smart expressway is visible in the whole network of expressway, measurable bridges and tunnels in key sections, controllable emergency management, big data application, multi-department information sharing, more personalized and customized service products, etc.

Industry Status of Smart Speed

Energizing the three major electromechanical systems of expressways in the past two decades has made its digitalization, automation and intelligence the main theme of building intelligent expressways, and has also made great contributions to the efficiency, safety and green of the expressway system. With the rapid development of technology, many people in the industry now replace "intelligence" with "wisdom," which reflects the industry's higher requirements for intelligent traffic.

We have done a lot of intelligent work on the expressway system, such as ETC, autonomous card issuance, automatic license plate recognition and other intelligent high-speed applications have been developed for many years, with the increasing demand for traffic travel in society, but there are still some problems: low charging efficiency, traffic jam at toll stations, serious traffic accidents often occur on expressways, dangerous vehicles, over-limit vehicles frequently violate regulations causing road damage and accidents. Therefore, highways urgently need further intelligence, automatic and intelligent matching with vehicles, digital matching with road infrastructure, and high standards and strict requirements of the environment.

Excellent case in the industry

Huawei's C-V2X solution: It is understood that Huawei's C-V2X solution can enable vehicles to realize non-line-of-sight roadside sensing, realize collaboration among people, vehicles and roads in various application scenarios, thus improving driving safety and efficiency, and serving more information for ×××. For example, when the vehicle is driving at the maximum design speed of 80km/h on Yanchong Expressway, a lane 100 meters ahead has an accident or emergency braking, and the driver of the following vehicle can receive danger warning within 100 milliseconds through C-V2X, thus avoiding the occurrence of secondary accidents. At present, the whole C-V2X vehicle-road collaboration standard is gradually being formulated and improved.

Nanshangdeng Expressway in Henan Province: Nanshangdeng Expressway took the lead in the field layout of the first full ETC lane in Henan Province, and the first ETC free-flow toll station was officially opened and operated. All ETC lanes, as the name implies, all cancel artificial toll lanes and windows. ETC free-flow mode means canceling toll stations. The free-flow mode is to erect a special ETC antenna 200 meters before the exit of the expressway toll station. When the vehicle passes through the gantry with special ETC antenna at a speed below 110 km/h, the toll will be paid in advance. After the transaction is successful, when entering the toll station, only verification is required to pass quickly.

Smart high-speed solutions of China Communication Service Group: In recent years, China Communication Service Group has been actively transforming and launching its own smart products. Its smart high-speed solutions integrate information technologies such as Internet of Things and cloud computing, covering three major fields of high-speed information monitoring, charging and network. In terms of monitoring, it has cross-regional and province-wide networking monitoring capability; in terms of charging, it has non-stop and non-inductive payment; in terms of operation and maintenance, it has professional focus and carrier-level IT and network operation and maintenance. In addition, it also has a practical big data platform. The big data platform is based on CCS open Internet of Things platform independently developed by China General Service. China General Service has built a provincial big data platform at Hunan Smart Expressway, helping Hunan Expressway Administration to form a comprehensive monitoring system and complete business management and control mechanism, which has been highly praised by all walks of life.

As one of the Internet of Things application fields with great development potential and prospect, intelligent transportation has extensive market opportunities and urgent user needs. PASS platforms such as Huawei's Internet of Things cloud platform and CCS open Internet of Things platform of China Tongfu will play the responsibility of intelligent device connection and application enabling development, and complete market breakthrough with industrial resource interoperability and ecological construction.
