Abstract

The invention relates to a roadway congestion index prediction system (including a vehicle-mounted terminal), an analysis method and a prediction method. The roadway congestion index prediction system comprises a server and a vehicle-mounted terminal. The vehicle-mounted terminal comprises a controller, a wireless communication device and a positioning device. The positioning device is a high-precision multi-source positioning device. The vehicle-mounted terminal transmits the positioning information to the server. According to the technical scheme of the roadway congestion index prediction system, the server positions a vehicle on a lane through acquiring the high-precision and all-territory accurate real-time position of the vehicle running on the lane. Meanwhile, the server calculates the real-time congestion index of the lane / road according to preset road occupied coefficients for various types of vehicles. Moreover, the server predicts a future congestion index according to recorded historical congestion indexes. Therefore, the traffic management and the traffic navigation are facilitated.

Description

technical field [0001] The invention relates to traffic management, in particular to a lane congestion index prediction system, a vehicle terminal, an analysis method and a prediction method. Background technique [0002] The road congestion index can be used to reflect the vehicle density on the lane or road. Road vehicle flow and road congestion index are important basis for traffic design, traffic management, and traffic navigation; especially real-time road congestion index can be used for real-time traffic management and traffic navigation; vehicle flow and road congestion accurate to the lane level The index is an important basis for traffic design, traffic management, and traffic navigation; real-time traffic flow and road congestion index accurate to the lane level are of great significance to real-time traffic scheduling and traffic navigation. [0003] The positioning accuracy of the existing differential satellite positioning system can reach the millimeter level...
