Traffic light control system based on GPS navigation system

Abstract

The invention discloses a traffic light control system based on a GPS navigation system. The traffic light control system comprises a traffic light management system, a GPS navigation system, a prejudging system and a reminding system, wherein the traffic light management system controls the state of signal lights; the position of the traffic lights is marked on a display terminal of the GPS navigation system; a timing module is arranged in the GPS navigation system and displays the state of the traffic lights on the display terminal; the prejudging system comprises a distance module and a computation module; the distance module sends computation signals to the computation module when the distance from a vehicle to a road junction is equal to a preset threshold value; the computation module evaluates the state of the signal lights when the vehicle arrives at the road junction according to the vehicle speed and the state of the signal lights; the reminding system comprises a judging module and a reminding module; and the judging module judges whether the vehicle speed needs to be adjusted according to the state of the signal lights and sends the result to the reminding module. The traffic light control system can display the state of traffic lights on the navigation system, thereby avoiding blind follow-up, emergency braking and disobeying of traffic lights, and ensuring trafficsafety.

Description

technical field [0001] The invention relates to the technical field of road safety management, in particular to a traffic signal light control system based on a GPS navigation system. Background technique [0002] Traffic lights are composed of red lights, green lights, and yellow lights. At the crossroads, red, yellow and green traffic lights are hung on all sides. It is a silent "traffic policeman". A red light is a stop signal and a green light is a go signal. At the intersection, cars coming from several directions gather here, some will go straight, some will turn, and whoever is allowed to go first, here it is to obey the traffic light command. When the red light is on, it is forbidden to go straight or turn left, and the vehicle is allowed to turn right under the condition of not hindering pedestrians and vehicles; when the green light is on, the vehicle is allowed to go straight or turn; When the light flashes, it warns the vehicle to pay attention to safety. It ...

AI Technical Summary

Problems solved by technology

[0003] However, when the vehicle is running, although there are traffic lights at the intersection, there are still some problems. For example, when arriving at the intersection of traffic lights, the lights often change suddenly. If there is no early deceleration, emergency braking is required. , or running a yellow light, which has potential safety hazards such as rear-end collisions; when driving, there are large vehicles in front of the traffic signal lights, so that the vehicles behind cannot see the signal lights, and the situation of blindly following the car and running lights occurs; or in the traffic signal light circuit When a fault occurs, if there is no manual command of the traffic police, vehicles in all directions often drive randomly, causing serious traffic jams, and traffic accidents are very likely to occur
