A real-time, dynamic, and accurate traffic information database is an important support for promoting innovation in transportation management, an effective way to improve transportation management and service levels, and a necessary means to build "smart transportation". The traffic information collection network centered on automotive electronic identification is conducive to building a massive, accurate, real-time, and standardized traffic big data platform by collecting vehicle data and traffic information from various road sections in the city. And apply new generation information technologies such as cloud computing and big data to aggregate and mine various types of traffic information, providing reliable decision-making references, command and dispatch functions for traffic management departments, and providing convenient, fast, and rich transportation services for the public. At the same time, it is conducive to achieving intelligent, integrated, networked, dynamic, service-oriented, and standardized traffic management.
