At present, autonomous driving is mainly used in some limited low-speed scenes, such as logistics distribution, travel, public transportation, sanitation operations, ports and docks, intelligent mines, unmanned retail and other fields. Autonomous driving is the product of the deep integration of the automobile industry, new generation information technologies such as artificial intelligence, high-performance computing, big data and Internet of Things, as well as transportation and urban management. It has a far-reaching impact on reducing traffic congestion and accident rate, helping cities to build a safe and efficient future travel structure, and on the reform of automobile industry and urban traffic planning.
