[Explanation] The National Science and Technology Innovation 2030 of the Ministry of Science and Technology - a new generation of artificial intelligence major project "Holographic Perception and Digital Twin Technology and Application Demonstration of Highway Traffic System" was launched in Chengdu, Sichuan on February 24.
On the same day, China's first application that integrates intelligent high-speed vehicle-road coordination technology with vehicle-machine navigation was officially released, which can make ordinary vehicles more intelligent.
It is reported that there are currently two main technical routes for autonomous driving: single-vehicle intelligence and vehicle-road coordination.
Compared with single-vehicle intelligence, vehicle-road collaboration integrates cloud computing, big data, and artificial intelligence to allow vehicles, roads, and clouds to realize interconnection and coordinate all traffic elements globally.
The first domestic all-weather lane-level precise navigation APP released this time, relying on the 157-kilometer-long domestic first smart expressway with full coverage of vehicle-road coordination—Chengyi Expressway, can provide passing vehicles with a "universe" that cannot be achieved by their own sensors. Viewing angle” to enhance beyond-horizon perception.

A smart pole is deployed on the roadside (every) 800 meters, and then the smart pole is equipped with a trigger (camera), a fisheye (camera), a bayonet (camera), a radar, and a smart cabinet below , The smart cabinet is equipped with some such as network transmission equipment, as well as AI computing equipment.
In layman's terms, we have installed a lot of "eyes" and "ears" on the entire smart highway, and installed a lot of "brain" calculations, so that we can see all road sections and all situations.
[Explanation] At present, Chengyi Expressway can identify and make intelligent decisions on abnormal traffic events such as abnormal parking and foggy weather, and the number of traffic accidents has decreased by 60% year-on-year.
Relevant staff told reporters that compared with the time-consuming and laborious search of the accident scene by camera in the past, it is now more efficient to handle accidents on Chengyi Expressway.
[Same period] Li Qiujie, dispatcher of Chengyi Expressway dispatching center of Shudao Group
In the past (expressway) incident handling, the time for the staff to manually edit the information may take a long time. Now that there is an online handling process, our AI will automatically detect (accidents) and report, and we do not need to manually Manually find where the traffic accident occurred.
The detection time of the AI is about two seconds, and the detection can be reported to the (staff). The staff can pass the information to multiple departments within about 30 seconds, and the follow-up road patrol personnel will arrive. The scene is about 10 minutes, and the rescue work can be carried out at the scene.
[Explanation] The reporter learned that after installing the APP on the mobile phone, the driver can not only see the high-precision positioning of his own car, but also see the driving conditions of the nearby vehicles for several kilometers.

The APP cooperates with the new generation of ETC on the car. The first thing is to get the high-precision positioning of the car, and the positioning is at the centimeter level.
Which lane you (driving) are in can be clearly displayed on the APP.
There is also a situation about our weekly cars, you can see (on the APP) the cars that are one or two kilometers away.
For example, a traffic accident occurred on the road. When the monitoring center knew about it, the drivers and passengers also knew about it.
In rainy and foggy weather or at night, you can’t see this (situation) clearly, and then through the navigation APP, you can see the surrounding conditions of the vehicle on the entire road.
For example, when overtaking, the road sensing device can give (the driver) a reminder as to how many kilometers it is safer to overtake.
[Explanation] It is reported that the project is expected to establish 6 sets of model systems and platforms, formulate no less than 8 relevant national and industry standards, and carry out application demonstrations of over 1,100 kilometers of expressway networks in Sichuan and Beijing.
