Traffic signal lights are generally set at intersections, using red, yellow, and green lights, which change according to certain rules, so as to direct vehicles and pedestrians to pass in an orderly manner at the intersection. Common traffic lights mainly include command lights and pedestrian crossing lights. What are the warning functions of Jiangsu traffic lights and traffic lights? Let’s take a closer look at them with Qixiang Traffic Equipment Co., Ltd.:
1. Command signal lights
The command signal light is composed of red, yellow and green lights, which change in the order of red, yellow and green when in use, and direct the traffic of vehicles and pedestrians.
Each color of the signal light has a different meaning:
*Green light: When the green light is on, it gives people a feeling of comfort, tranquility and safety, and it is a signal of permission to pass. At this time, vehicles and pedestrians are allowed to pass.
*Yellow light: Yellow illusion – when it is on, it gives people a sense of danger that needs attention, and it is a signal that the red light is about to come on. At this time, vehicles and pedestrians are not allowed to pass, but vehicles that have passed the stop line and pedestrians who have entered the crosswalk can continue to pass. In addition, when the yellow light is on, right-turning vehicles and straight-going vehicles without pedestrian crossings on the right side of the T-shaped intersection can pass.
*Red light: When the red light is on, it makes people associate with “blood and fire”, which has a more dangerous feeling, and it is a signal of prohibition. At this time, vehicles and pedestrians are not allowed to pass. However, right-turning vehicles and straight-going vehicles without pedestrian crossings on the right side of T-shaped intersections can pass without hindering the passing of vehicles and pedestrians.
2. Pedestrian crossing signal lights
Pedestrian crosswalk signal lights are composed of red and green lights, which are set at both ends of the pedestrian crosswalk.
* When the green light is on, it means that pedestrians can cross the road through the crosswalk.
*When the green light is flashing, it means that the green light is about to change to a red light. At this time, pedestrians are not allowed to enter the crosswalk, but those who have already entered the crosswalk can continue to pass.
*Pedestrians are not allowed to pass when the red light is on.
