Traffic signal lights, commonly known as “traffic lights”, are indispensable indicator lights for our daily travel, and they are used at all intersections in the city. The sentence “stop the red light, go on the green light, wait until the yellow light is on” fully embodies the meaning of the three colors of traffic lights. Signal lights are used at intersections and can be seen everywhere when walking on the street. Red, green, and yellow lights are constantly flashing to give directions to vehicles and pedestrians to move or stop. Traffic signal lights are a necessary facility for urban construction, and they have the following functions.
1. Mitigation of traffic: The traffic of a city is greatly affected by traffic light control. When the traffic flow and the flow of people are both saturated, the traffic signal light can effectively play a commanding role. Proceed or stop according to the signal light to make it arrive at the same time. People and vehicles on the road should reduce interference as much as possible, so as to improve the traffic capacity of the intersection and ensure the smooth flow of the intersection.
2. Protect everyone’s personal safety: A large number of cars and people are prone to congestion on traffic roads, and rushing forward is prone to traffic accidents. People can avoid traffic accidents and ensure safety by following the rules of traffic lights.
Traffic signal lights can effectively alleviate urban traffic pressure and ensure the safety of the people. At intersections, you must obey the signal light rules, and you must not follow the public and have a fluke mentality-“safe travel, everyone is responsible!”
