Features and Advantages
? Successfully set up the city's first test site. 10.67 kilometers of urban roads in the area have been opened, covering 15 urban public roads and 30 intersections. The test area is equipped with traffic signal control system, traffic video monitoring system, traffic law enforcement system (electronic police), RFID electronic fence and other infrastructure, and has a navigation and positioning base station (compatible with GPS, Beidou signal), high-precision map and other auxiliary foundations. Facilities to meet the requirements of intelligent networked road testing.
? Realize the establishment of national recommended industry standards. Relying on the construction of the pilot zone, two national industry-recommended standards "Car-Road Collaborative Cloud Control Basic Platform: General Requirements" and "Car-Road Collaborative Cloud Control Basic Platform: Test and Evaluation" have been formed. The project is currently being approved, standard check and professional Terminology revision, the overall standard compilation is expected to be completed within this year.
Application (Where & How)
? The 5G wireless backhaul technology was verified for the first time. Cooperated with Zijinshan Laboratory to study the use of China’s first 5G independent networking in L4 autonomous vehicles. The 5G-V2X private network has been completed, and the 5G wireless backhaul scheme has been verified for the first time, with a delay of 8-10 milliseconds (continuous optimization in the later period) Upgrade), which can basically replace traditional optical fiber links, and can support the development and application test of new technologies such as new intelligent communications for B5G/6G.
?Widely use local new technologies and new products. According to the overall architecture of "a set of foundation", "one platform", "three supports", and "four types of services", the pilot zone has carried out the construction of the intelligent transportation digital base, and successfully built a cloud control platform, high-level autonomous driving, and car networking assistance. Driving three sub-application scenarios, successfully adsorbed RSU roadside units, cameras, sensing software, millimeter waves of local companies such as Laisi Netcom, HuierTV, Xeikon, Future City, Purple Mountain Laboratory, Huawei, and AsiaInfo. The use and promotion of new products and technologies in the city, such as radar, smart signs, 5G private networks, and public clouds.
Comments on the Solution
After obtaining the first batch of unmanned driving test licenses in Nanjing on December 19, 2020, and realizing the first test of unmanned vehicles in the city, the intelligent network connection test road in the pilot area will be officially tested from January 1 to March 15, 2021. Autopilot tests were conducted on 3 unmanned vehicles. The total test time has reached more than 400 hours, and the total test mileage has reached 5,449 kilometers. The test scenarios include congested roads, red light warning, speeding vehicle reminders, and full obstacle recognition at intersections. 40 An accident-prone test scenario.
