Today, everyone knows the traffic lights, with red, orange and green. But one day that may change.

Innovative traffic light

Indeed, in the near future our traffic lights may well be decoratedfourth color : White. This bold proposal comes from a team of American researchers, and it could fundamentally change the way we approach road safety, traffic flow, and even our environmental impact. Let’s dive into this futuristic vision and explore how they four-color headlights can change our daily lives. Researchers at North Carolina State University studied the benefits of adding a fourth color to traffic lights at intersections. In their experiments, this color was white. His role? We are leading drivers into a new era: driverless cars. These vehicles will “communicate” with other autonomous cars scattered at various points in the intersection, as well as with traffic lights. If this fourth color is not needed, the intersection will work in the classic way. But when driverless cars are present, in some cases the white light will allow them to pass.

Fire with many benefits

The study shows that this intelligent system will make traffic flow more smoothly. Travel time will be reduced by 3% if there are few autonomous cars at intersections. No more endless waiting at red lights, no more constant starts and stops that increase fuel consumption. Four-color headlights will ensure smoother and more efficient work of drivers. But in addition to improving traffic flow, this technology will have a positive impact on the environment. Less waiting at red lights actually means less CO2 emissions. The start-and-stop effect of cars will be reduced, saving both our wallets and the planet. However, although this technology has proven itself in the laboratory, its implementation on the roads will not happen immediately. Still, researchers remain optimistic and hope to soon see these four-color lights illuminating our intersections, perhaps even in some ports.

In short, four-color lighting may well be the key to a safer, smoother, and greener future.
