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

Abstract

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.

Description

Technical field [0001] The invention relates to the technical field of traffic control, in particular to a signal lamp state terminal display method and system based on vehicle-road coordination technology. Background technique [0002] At present, there are many traffic lights on the road that do not have time to display, or due to obstructed vision or extreme weather, the driver cannot correctly judge the time to pass the intersection or the time to wait for the signal light, which affects driving safety , Increasing the pressure of road traffic. Although the patent number 201410157544.9 realizes the real-time display of signal light information in the car, it is vulnerable to the influence of the environment, the vehicle and the driver, causing problems such as invalid traffic light information or too short driver response time, resulting in low system efficiency. Neither the accidental red light running nor the traffic accident rate can be well improved and controlled. Summ...
