Traffic lights
are essential traffic safety devices designed to enhance the management of road traffic safety and prevent traffic accidents. They help improve road usage efficiency and promote better traffic conditions. They are one of the most important traffic tools and are most commonly found at intersections.
Traffic lights are controlled by a traffic signal controller, which guides vehicles and pedestrians to pass safely. Traffic lights are standardized nationwide and consist of three colors: red, green, and yellow.
The red light indicates that passage is prohibited, the green light permits passage, and the yellow light signals vehicles to slow down or serves as a warning. According to our country’s implementation regulations of the road traffic law, traffic lights are categorized into several types: signals for non-motor vehicles, signals for motor vehicles, lane signals, pedestrian crossing signals, direction indication signals, warning flashing signals, and intersection signals.
The role of traffic lights is substantial. As everyone knows, red means stop and green means go. Red represents a warning of danger, while green signifies safety. Traffic lights not only indicate traffic rules but also serve as behavioral indicators for people, informing them of appropriate actions to take and actions to avoid. Traffic lights remind people not to run red lights, to avoid spitting or littering, to refrain from vandalism, and to avoid using uncivilized language.
Installed at intersections, traffic lights have become one of the most effective tools for directing vehicle flow and maintaining traffic order, resulting in orderly vehicle movement.
