Road vehicle management system with multistage early warning function

The invention discloses a road vehicle management system with a multi-stage early warning function, belongs to the technical field of road vehicle management, and aims to solve the technical problem that accident loss is enlarged due to the fact that early warning signals cannot be generated in advance in the prior art. According to the system, road vehicle information is analyzed through an early warning detection unit so as to detect a vehicle on a road, the real-time speed of the vehicle on the road, the duration of the vehicle staying in a non-parking area on the road and the difference value between the average speed of a vehicle staying area and the average speed of the vehicle leaving the vehicle staying area are acquired, and an accident analysis coefficient Xi of the vehicle on the road is acquired through a formula; the accident analysis coefficient Xi of the road vehicle is compared with an accident analysis coefficient threshold value; and the road vehicle is analyzed, whether the vehicle has an a
