From the south line of Chengdu Tianfu International Airport Expressway, you can reach Yibin City in about 90 minutes. Along the way, weather sensors, high-precision cameras, car networking equipment, edge computing equipment, etc. appear on the roadside from time to time; in the background, high-tech such as cloud computing, big data, artificial intelligence, etc. run through the operation and monitoring...Scenarios like this appear On this digital "cloud" of the entire process, the expressway-Cheng (Du) Yi (Bin) Expressway. Chengyi Expressway was officially opened to traffic at the end of 2020. Thanks to the blessing of digital and intelligent systems, the expressway travel experience is becoming more comfortable and safer.

Smart high speed allows travel to experience the speed on the cloud

The total length of Chengyi Expressway is about 157 kilometers. It starts at Chengdu Tianfu International Airport and ends at Yibin Ring Expressway. The total investment is 24.6 billion yuan. The construction of the entire line is two-way six-lane construction. It is invested and constructed by Sichuan Railway Investment Group and is designed in Sichuan Province. One of the highway projects with the highest standards. A total of 157 bridges, 4 tunnels, and 17 interchanges are set up across the line, with a design speed of 120 kilometers per hour.

Chengyi Expressway is one of the 16 Chengdu radial expressways in the "Sichuan Expressway Network Plan (2014-2030)", and it is also an important part of the "two corridors and four passages" in the province's southward expressway channel layout. With this highway, the Chengdu Plain Economic Zone and the Southern Sichuan Economic Zone have the shortest and most convenient connection channel.

As the second batch of pilot provinces as a powerful transportation country, Sichuan Province’s construction pilot implementation plan was approved by the Ministry of Transport in November 2020. Among them, Chengyi Expressway has become one of the key projects of the plan, as well as the "New Infrastructure Demonstration Project" in Sichuan Province and the "First Batch of Demonstration Projects" in Sichuan Province, a strong transportation province.

Where is the demonstration effect of a strong country pilot and a strong province demonstration? Zhou Yong, chairman of Sichuan Digital Transportation Technology Co., Ltd., pointed out that in the construction process of Chengyi Expressway, the world's leading cloud computing, artificial intelligence, high-precision weather, intelligent perception, high-precision positioning, lane-level navigation, and intelligent guidance control are applied. Other technologies are veritable "smart highways".

According to reports, Chengyi Expressway is the first all-element, full-coverage smart expressway in Sichuan Province. The overall construction includes three parts. The first part is to support "autonomous driving". Pilot road sections are selected to support the construction of autonomous driving infrastructure to meet the standards for supporting L4 autonomous driving. The second part is the “vehicle-road coordination” across the entire line, building a complete highway network intelligent perception management and control system, and realizing active vehicle safety control and road collaborative management. The third part is the full line of "smart highways". Based on the new digital infrastructure to create a full range of smart capabilities, passengers will enjoy safer, more comfortable, and faster smart travel on the Chengyi Expressway.

Jingyan Bay Bridge.

The "smart highway" is by no means a simple stacking of new technologies. It is understood that Sichuan Railway Investment Group has formed a joint laboratory with Alibaba Cloud and other cutting-edge technology companies to solve old problems through new technologies and realize digital and refined expressway services. For example, based on the full coverage of Alibaba Dharma Academy’s full coverage of Lei (Da) video (frequency) fusion core technology, to provide all-weather traffic service guarantee for expressways; based on Beidou’s high-precision space-time positioning capabilities, it can provide one for tens of thousands of devices and vehicles. Lane-level positioning within seconds; omni-media user information access can provide high-precision lane-level accompanying services, allowing car owners to get real-time accurate push of road conditions from App and channels, and truly experience "cloud" travel.

Create a new era of smart high-speed model

Chengyi Express has created a "digital parallel world" through millisecond-level digital twin technology. Dr. Chen Ken, Director and Deputy General Manager of Sichuan Digital Transportation Technology Co., Ltd., and Dean of the Future Transportation Engineering Institute, introduced that Chengyi Expressway is based on lane-level high-precision 2D/3D map modeling and real-time splicing of Ray Vision trajectory data, so that it can be day and night. Affected by light, rainy and foggy days are not affected by the harsh environment, and real-time high-speed facilities and equipment, as well as traffic, speed, abnormal events, dangerous road conditions, and extreme weather are digitalized and restored in real time, and the vehicles, equipment, facilities, The visualized panorama of situational awareness can provide a new service experience of "God's perspective" vehicle following and vehicle-road collaborative remote virtual driving.

Chengyi Express has created a "digital parallel world" through millisecond-level digital twin technology.

At the operational level, Chengyi has taken the lead in realizing the transformation from an infrastructure operator to a data resource service provider, and has made six major improvements from the direction of business digitization, namely collaborative operation, data assets, driving safety, efficient traffic, and travel. Accompanying and industrial ecology.

The road is completed and the road to Shu is no longer difficult. The completion of the Chengyi Expressway, from design and construction to management and operation, has the collaboration of vehicles and roads, and the integration of wisdom and services, planning a new model of people's future travel with advanced concepts. Zhou Yong stated that, as an original digital express brand for "ecological service sharing", Chengyi Expressway will work hard to build a model in the new era of accelerating the journey of building a strong transportation country, and provide the people with reliable, high-quality, and more advanced travel services. .
