Technical Field
The utility model relates to the technical field of road traffic, in particular to an intelligent traffic light system.
Background
At present, traffic lights are often arranged at intersections and pedestrian crossings of urban roads so as to provide indicative notices for driving and pedestrians to cross roads. The traffic light is significant to the life of people. However, in a few cases, the traffic lights arranged at the intersections cannot meet the traffic demands, when special situations such as power failure occur, emergency traffic lights are often needed to assist in directing traffic, and the road traffic signal lights are one category of traffic safety products and are important tools for enhancing road traffic management, reducing traffic accidents, improving road use efficiency and improving traffic conditions. The traffic signal lamp is an important component in traffic signal command and is a basic language of road traffic. The traffic signal lamp is composed of a red light (indicating no passage), a green light (indicating passage permission) and a yellow light (indicating warning). The method comprises the following steps: motor vehicle signal lamp, non-motor vehicle signal lamp, pedestrian crossing signal lamp, lane signal lamp, direction indicating signal lamp, flashing warning signal lamp, road and railway crossing signal lamp. The light sensitive material is widely used for dangerous road sections with potential safety hazards at road intersections, curves, bridges and the like, commands drivers or pedestrians to carry out traffic, promotes smooth traffic, and avoids traffic accidents and accidents. Due to this visual structure, humans most easily distinguish between red and green. Although yellow and blue colors are also easily distinguished, it is preferable to distinguish between red and green colors because the eye has fewer photoreceptor cells sensitive to blue light.
