Description
Technical Field
The invention relates to the technical field of traffic lights, in particular to an intelligent red-green light with high warning performance.
Background
The traffic signal lamp consists of a red lamp, a green lamp and a yellow lamp. The red light indicates no traffic, the green light indicates permission, and the yellow light indicates warning. The traffic signal lamp is divided into: motor vehicle signal lamp, non-motor vehicle signal lamp, pedestrian crossing signal lamp, direction indicating lamp (arrow signal lamp), lane signal lamp, flash warning signal lamp, road and railway crossing signal lamp. At the crossroad, traffic lights of three colors of red, yellow, green and green are hung on four sides, which is a traffic policeman without speaking. Traffic lights are internationally unified traffic lights. The red light is a stop signal and the green light is a pass signal. At the intersection, vehicles coming from a plurality of directions are converged at the intersection, some vehicles need to go straight, and some vehicles need to turn around, so that the people can walk first, and the traffic light is called to be instructed. The red light is on, the vehicle is prohibited from going straight or turning left, and the vehicle is permitted to turn right under the condition that pedestrians and vehicles are not hindered; the green light is on, and the vehicle is allowed to go straight or turn; the yellow light is on and can continue to pass beyond the intersection stop line or the pedestrian crossing line; when the yellow light flashes, the vehicle is warned to pay attention to safety.
The appearance of the signal lamp can effectively control traffic, and has obvious effects of dredging traffic flow, improving road traffic capacity and reducing traffic accidents. In 1968, the United nations 'road traffic and road sign signal Agreement' stipulated the meaning of various signal lights. Green lights are traffic signals and a vehicle facing a green light may go straight, turn left and turn right unless another flag prohibits a particular turn. Both right and left-turning vehicles must give priority to vehicles that are legally traveling in the intersection and pedestrians that cross the crosswalk. The red light is a no-go signal and a vehicle facing the red light must stop behind a stop line at the intersection. A yellow light is a warning signal and a vehicle facing the yellow light cannot cross a stop line, but can enter the intersection when the vehicle is in close proximity to the stop line and cannot safely stop. Since then, the regulation is universal around the world, the existing traffic lights are generally used in the form of circular LED lights, and the waiting time and the passing time are displayed at the same time, but the circular lamps are small in target, the warning performance is not obvious enough at a busy intersection, and pedestrians or drivers easily ignore the traffic lights to cause traffic accidents.
