5 hubs are interconnected with multiple high-speed lines in Sichuan
Chengyi Expressway starts from ChengduEconomic zoneDowntown Qingfeng on the Jianpu section of the Ring Expressway (known as “Chengdu” Three Rounds “), connects with the South Line of the Chengdu Tianfu International Airport Expressway and passes through the New Eastern District of Chengdu, Jianyang City , Renshou County of Meishan City, Weiangiyuan County of Neij City, Rong County of Zigong City, Xuzhou District and Cuiping District of Yibin City stop at the center of Zhongfeng Temple from Leyi Expressway and connect to the western section of Yibin City Transit Expressway.

The entire line has six bi-directional lanes and a design speed of 120 kilometers per hour, it is one of the highway projects with the highest design standards in the province.
Total line configurationbridgeThere are 157, 4 tunnels and 17 interchanges. Among them, 5 hubs are interconnected, connecting many expressways in Sichuan: downtown Qingfeng is connected to the southern line of the Chengdu Tianfu International Airport Expressway, which can be converted into the Chengdu three-loop Jianpu Expressway; in central Fujia, it can be turned into the Sui-Zimei Expressway; Downtown can be turned into the Zilu Highway; in the center of Rongzhou, it can be converted into Lezi Expressway; In downtown Zhongfengsi, it can be turned into Leyi Expressway, which connects with the western section of Yibin City Transit Expressway.

Create high-speed digital for accurate lane-level navigation
On December 17, with the cold wind and drizzle, the reporter started a test before the opening of the Chengyi Expressway. From the starting point of downtown Qingfeng in the Jianpu section of the “three windings” of Chengdu to the 10 km section of Longma City, Renshou County, Meishan, the “autonomous driving” infrastructure is being deployed along the route.
“What I am installing behind me are smart devices on the road, including weather sensors, high-precision cameras,Vehicle InternetEquipment, edge computing equipment, etc. “Sichuan Chengyi Railway Investment Groupthe companyGeneral ManagerYang Dawei said: “With the support of algorithms and cloud applications, accurate lane-level navigation will eventually be achieved.”
In 2019, the Chengyi Expressway project was included in the Sichuan Province “Transportation Power” pilot project, the main figure of the United Nations Sichuan Railway Investment Group.companyEstablish a joint laboratory to address key issues and integrate high speed digitalCore technologiesIn other words, the most advanced vehicle-road collaboration technology.
Yang Dawei introduced that Chengyi Expressway has implemented vehicle-road collaboration technologies, including cloud computing,Big data、artificial intelligence, Digital meteorology, holographic perception, high precision map, high precisionPositioning, Lane-level navigation, all-weather traffic, etc.
It is reported that the Chengyi Digital Highway will be built in three phases: the first phase will be “autonomous driving”, with 10 kilometers of “automatic driving” infrastructure installed in the initial stage, reaching the L3.5 level of autonomous driving standards. ; the second phase will be “vehicle-road coordination”, To build a complete intelligent perception system of the road network to perform the functions of artificial intelligence video analysis, prediction and alarm for the entire section; the third phase is “smart highway”, based on the construction of new digital infrastructure, to achieve 5G coverage of the entire section. The first construction phase is expected to be completed in May 2021.

Proposal for a super service area to carry out “traffic + tourism + technological experience”
In accordance with the requirements of the “New Infrastructure Demonstration Project” in the “Action Plan to Accelerate the Promotion of New Infrastructure Construction in Sichuan Province (2020-2022)”, Chengyi Company intends to build a super service area within the territory of Longma Town, Meishan, Tianfu New District to create a “traffic + tourism + Technology Experience Project”.

According to the preliminary plan, the total area of the project is estimated at about 500 acres. The basic functions of the service area include restaurants, hotels, recreation and sports, parks, squares, supply facilities,cultureActivities, unmanned driving experience area, recharging and refueling batteries, etc. In the service area, you can also check flight information in real time.
Construction of the service super area is reported to begin one year after the entire line is open to traffic.

After the full line of Chengyi Expressway opens, it will only take 90 minutes to reach Yibin from South Line of Chengdu Tianfu International Airport Expressway; It only takes 2.5 hours from Chengdu Third Ring Road to Yibin, which is about 1 hour shorter than the current trip.
Traffic in Sichuan provincetransportThe relevant person in charge of the room explained that at present, it is necessary to take the Chengle Expressway or Chengzi-Lu Expressway from Chengdu to Yibin, and there are some detours. The Chengyi Expressway can be compared with the Chengdu-Yuzhong line high-speed railway, which is a straight line.
“It is the highway with the highest design standards from Chengdu to the city, and it is also the most convenient southbound passage from Sichuan to Yibin via Yibin.” Yibin City Transportation OfficeInvestigationMember Chen Jian said. Chengyi Expressway connects Tianfu International Airport and Yibin Port, and is an important route for air transportation; It also connects the South Sichuan Economic Zone and the Chengdu Plain Economic Zone, which has an impact on the economy.societyDevelopment has a very large driving effect.
