Are you going overseas? Then you should know the fourth color that can appear at traffic lights.
It is said that the first traffic light was launched on December 10, 1868 at the intersection in front of the London Parliament. At that time he had two colors – red and green. The first of the shades meant standing and the second – go. Then to this pair of colors was added yellow (sometimes flashed like orange), which is supposed to be a “preparation” for the driver to start…

White color just for the chosen
The traffic light is simply a helper in transport and prevents unnecessary accidents. Currently, another color is being considered – white. It should appear at traffic lights in the US, where new, autonomous vehicles are in operation. It is a type of vehicles that do not need drivers for their operation but are controlled by computer. Their independent orientation on the street is possible thanks to various detectors such as Radar, Lidar, satellite navigation and others… San Francisco in this way runs test autonomous taxis…
New type of car
The operation of autonomous vehicles is currently more of a matter of superpowers such as the US and China. Europe is still lukewarm to their acceptance, although Germany and France are considering their introduction. According to experts, these “carts” should bring less accident rate, especially on highways, where thousands of people die every year because of accidents… According to Goldman Sachs, autonomous cars should make up to 10 % of car sales by 2030.
Signaling at intersections
And that is why there should be a white color at traffic lights, which should be used mainly at intersections. “This signal should appear if there are more autonomous vehicles around. Thanks to the signaling device, it could communicate better with each other and each of them would create their time plan on how they would go through the intersection, ”concludes the expert.
