With the development of modern urban construction and road traffic, there are more and more vehicles, and the contradiction between vehicles and roads, as well as the contradiction between traffic and environmental energy, is becoming increasingly acute. There are more and more cases of motor vehicle theft and robbery, and dangerous driving behaviors such as driver fatigue have brought great pressure to traffic management departments.
People have been committed to finding the best solutions to manage traffic congestion, strengthen vehicle scheduling, and provide distress alerts. The application of GPS Beidou global satellite positioning system has shown people the hope of intelligent urban traffic management in the future. In recent years, the Ministry of Transport/Public Security of China has designated a complete set of industry standards for the positioning, monitoring, alarm, command and dispatch, and information dissemination of motor vehicles, especially a large number of hazardous chemical freight vehicles, passenger vehicles, and other public transportation. Two passenger and one hazardous vehicles must be equipped with intelligent alarm devices before going on the road, which plays a very positive role in improving traffic efficiency and reducing traffic accidents.
