Traffic Lights: The Universal "Safety Language" for Travel​

As a globally accepted traffic regulation, traffic lights have a history of over 150 years. In 1868, the world's first manually operated gas-powered traffic light appeared in London, with only red and green colors, used to control horse-drawn carriages. Although it had a short life due to a gas explosion, it pioneered modern traffic management.​

Today, the globally standardized red-yellow-green system is based on optical principles. Red light (620-750 nm) has the strongest ability to penetrate fog and represents "stop"; green light (495-570 nm) is highly recognizable to the human eye and represents "go"; yellow light (570-590 nm) serves as a warning transition. This system is consistent with the standards of the International Commission on Illumination (CIE).​

Technological innovations have continuously driven its development: electric traffic lights emerged in 1914, and LEDs replaced incandescent bulbs in the 1990s to improve energy efficiency. Today, not only do smart systems in cities like Singapore and Barcelona adjust timing through AI-driven traffic monitoring, reducing congestion by 20%-30%, but cities in China such as Beijing, Shanghai, and Shenzhen are also actively applying intelligent traffic lights. For example, at some intersections in Shenzhen, traffic lights can dynamically adjust their duration according to real-time traffic flow, effectively alleviating congestion during morning and evening peaks; some road sections in Beijing have piloted the "green wave belt" technology, allowing vehicles to maintain green lights at consecutive intersections, significantly improving traffic efficiency. These innovations that integrate physics and urban engineering have always been an important guarantee for global road safety.​
