Traffic lights can be drastically changed to increase safety

There are several resources used to make people safer in traffic, traffic lights They are the best known around the world.

Thus, despite its name changing depending on the region of Brazil, the device itself remains the same, featuring the colors red, yellow and green.

Therefore, each of them indicates a type of action that the driver should take. Green means follow, red means stop and yellow means caution.

However, recent studies are proposing the addition of a new color to this traditional palette, and today we will understand the reasons behind this and what color it is.

Why do they want to add another color to the traffic lights?

The suggestion for this new measure is mainly due to the recent popularization of automobiles autonomous, that is, they do not require human direction to move.

The idea would be to add a white light to the others already existing, in order to bring more fluidity to traffic in large cities.

According to researchers at North Carolina State University, in the USA, the new color would help alert surrounding human drivers to the existence of an autonomous car nearby.

Scientists believe this would help prevent accidents and delays in vehicle traffic.

In short, the white luminosity would serve to indicate that autonomous cars are coordinating their movements, which would help prevent traffic jams or collisions.

The suggestion is that this type of car can communicate with similar ones and also with other traffic lightsso that everyone can drive better.

Finally, as here in Brazil the number of automobiles of this type is still very low, the new system might not work as well, leaving citizens to wait and see how the situation will unfold.
