From the south line of Chengdu Tianfu International Airport Expressway, it can reach Yibin City in about 90 minutes. Along the way, the meteorological sensor, high -precision camera, and networking equipment of the car are assembled on the side of the road to provide real -time visual panoramic road conditions monitoring for the background. Vehicles that empower the driver "God's Perspective" follow the new experience of the road collaborative virtual driving ... … Such a scene appears on the "cloud" of the entire process of digitalization.

How wisdom is such a wisdom high speed? Where is "wisdom"? On June 27, Chengyi high -speed release of the first transcript after launching intelligent construction. Data show that the number of high -speed traffic accidents decreased by 60%year -on -year, and the number of "zero accidents" increased from 0.5 days a week to 1.8 days.

The panoramic dialysis of a tunnel of Chengyi High Speed

Chengyi high -speed line is about 157 kilometers in length and starts at Chengdu Tianfu International Airport. It stops at Yibin's around the highway. It is officially opened to traffic on December 31, 2020. It is the first full -scale and full -covered smart high -speed highway in Sichuan Province. highway.

"Smart Highway" is by no means a simple stack of new technologies. It is understood that Sichuan numbers have reached cooperation with scientific and technological companies such as Alibaba Cloud and Tencent to solve the old problems through new technologies, and realize the digital and refined services of highways.

The system simulates the rain and mist weather

For example, in view of the special environment of Chengyi high -speed multi -speed tunnel and cloudy fog, Chengyi high -speed and technology companies jointly developed the "full interest pupil" system, relying on software and hardware deployment and algorithm optimization, and achieved unparalleled gap monitoring on high -speed entire sections. In this system, people, cars, and environments can achieve accurate perception of full, all -weather, and whole process; it can also identify and intelligent decision -making on traffic abnormal incidents such as abnormal parking, heavy fog weather, and through the intelligence board, road side side, road side side, road side side Fog lights, broadcasting, etc. are precisely released on road conditions, reminding and inducing past vehicles in a timely manner to reduce the incidence of accidents.

At the same time, the driver can also access the digital scenario of the system for smart high -speed travel services. Compared with other navigation, it can completely project the scene of the road to the user's navigation interface. Users can feel the external driving environment through the digital scene, obtain road conditions information, and realize all -weather traffic.

In addition to reducing the accident rate, through the system's fully automatic work order processing process, the efficiency of high -speed traffic accident cases also increased by 20%, and the case handling time was shortened by 20 minutes.

It is understood that in the future, smart traffic solutions on the Chengyi high -speed speed will be widely used in the Sichuan Highway and Railway. In this regard, Chen Chin, the dean of the Institute of Transportation and Engineering in the future, believes that the needs of travel needs and service resources with data can not only achieve intelligence, but also need to incubate ship drainage, service area drainage, green travel and other operations based on this system. Scenes, realize the digital economy innovation of highway operations.
