Intelligent prompting system for traffic lights

Abstract

The invention relates to an intelligent prompting system for traffic lights. The intelligent prompting system comprises traffic light terminals corresponding to all fork roads respectively, and traffic light vehicle-mounted terminals corresponding to all vehicles. Each traffic light terminal comprises a first control module, a first satellite positioning module, a broadcast signal transmitter and a traffic light controller used for controlling traffic lights of the corresponding fork road to work. Each traffic light vehicle-mounted terminal comprises a second control module, a broadcast signal receiver, a second satellite positioning module, a gyroscope sensor and an information output device, wherein the broadcast signal receiver, the second satellite positioning module, the gyroscope sensor and the information output device are connected with the second control module. Unidirectional information transmission is conducted between the traffic light terminals and the traffic light vehicle-mounted terminals through the broadcast signal transmitters and the broadcast signal receivers. According to the intelligent prompting system, existing traffic lights are further designed, drivers can know the real-time working states of the traffic lights of the front fork roads in time, the defects of an existing driving mode are overcome, and normal and orderly operation of the road traffic is ensured.

Description

technical field [0001] The invention relates to an intelligent prompting system for traffic lights, which belongs to the technical field of intelligent transportation. Background technique [0002] Traffic lights usually refer to signal lights that are composed of red, yellow and green lights to direct traffic. When the green light is on, vehicles are allowed to pass. When the yellow light is on, vehicles that have crossed the stop line can continue to pass; Vehicle traffic. With the continuous improvement of living standards, the number of vehicles is increasing day by day, and the traffic road network has become more crowded and complex. The traffic lights used to direct traffic have also changed, from the initial simple light source to the Later, the direction of the light source was designed, including going straight, turning left, turning right, and U-turn, as well as the accompanying design of the countdown display, all of which gave vehicles and pedestrians more intu...

Problems solved by technology

[0005] Looking at the traffic light design in the prior art, it can be seen that the designers have provided many improvements and design schemes for the development of traffic lights, but in actual driving, traffic lights still have some problems, such as a small car following a When a big car passes through the intersection and the small car follows the big car, it is difficult to observe or even directly observe the situation of the traffic lights at the intersection. It is possible that the large car passes the stop line in the last few seconds of the green light, and when the small car passes the stop This is the trouble caused by large cars blocking the view of small cars. When it comes to traffic, regardless of size, the driving of vehicles is related to the safety of drivers, passengers and people around the vehicles. This kind of intersection The way of passing that blocks the line of sight has brought confusion to countless drivers and passengers, so this is a deficiency that still exists in existing traffic lights
