Signal lamp state terminal display method and system based on cooperative vehicle infrastructure technology

The invention provides a signal lamp state terminal display method and a system based on a cooperative vehicle infrastructure technology. The system comprises a traffic signal machine, a roadside module, a vehicle infrastructure communication module and a terminal device, wherein the traffic signal machine is used for generating signal lamp phase timing information and transmitting the information to the roadside module; the roadside module is used for publishing intersection position information, local MAP information and a real-time SPAT information; the vehicle infrastructure communication module is used for information data interaction between the terminal device and the roadside module; and the terminal device is used for acquiring, processing and displaying the vehicle motion state data and terminal information. The cooperative vehicle-infrastructure technology is used for realizing real-time displaying of the signal lamp state on the terminal device, a driver can conveniently judge the vehicle passing time and the queue time, the road traffic safety is enhanced, the road traffic pressure is reduced, influences from the environment, the vehicle and the driver do not exist, and the system use efficiency is high; and red lamp early warning or automatic control can also be realized, the intersection driving safety is ensured, and a behavior of running the red lamp to break the law can be avoided.
