Recently, the Longchi "Vehicle Road Collaboration" testing site, invested by Sichuan Communications Investment Group with over 80 million yuan, was officially completed and put into use. The simulation testing site is located in the Longchi section of the Duwen Expressway in western Sichuan. This section was closed after a major mudslide in 2009 and is currently a closed highway section that can meet 306 scenarios for autonomous driving testing and verification.Source | Sichuan JiaotouThe testing field adopts "multi-source sensor fusion technology", with high-definition cameras, millimeter wave radar, and laser radar sensors installed every 150 meters on the roadside. The green flashing device is a road stud laid flat on the road surface as a guide, which can sense the vehicle's self illumination and change different colors according to the distance between vehicles to alert the vehicles behind.In order to increase signal transmission efficiency and avoid signal blind spots, the entire testing site has also set up four 5G base stations, built 5G networks, intelligent roadside connections and other facilities, and combined with the Beidou positioning system to achieve information exchange between sensing devices and vehicles. Vehicles can perceive the information ahead of the road section in advance, making it safer and more convenient for vehicles that meet the requirements of autonomous driving to reach their destination.Compared with other testing sites, Longchi Testing Site is built based on the original highway section, which is more realistic and able to reproduce the actual situations often encountered on highway sections. At the same time, as the first vehicle road collaborative testing site in the southwest region, Longchi Testing Site currently adopts a non-profit model and provides various forms of differentiated testing projects such as closed site simulation testing, semi open roads, and open roads for the industry.Source | Sichuan JiaotouIt is reported that the total cost of the 2.6-kilometer test section is over 80 million yuan, which is a huge initial investment compared to ordinary highways. But the construction cost of the future 'smart highway' will significantly decrease.As a part of the new infrastructure of intelligent transportation, current vehicle road collaboration will further promote scheme optimization and reduce its construction and operation costs through preliminary experiments. At the same time, vehicle road cooperative assisted autonomous vehicles can drive autonomously on highways, laying the foundation for the next step of achieving autonomous driving on truly open highways. It is expected that by 2025, Sichuan Communications Investment Group will fully integrate the Duwen Expressway, Yingwen Expressway, and Ring Expressway into the future smart highway network construction, creating a 200 kilometer smart highway test network.Source: Red Star NewsIt is reported that the total cost of the 2.6-kilometer test section is over 80 million yuan, which is a huge initial investment compared to ordinary highways.
