However, it seems that in the future, maybe our traffic lights could be smart enough where no buttons are necessary and that they would simply turn red when it detects that we want to cross the street. This was developed using computer vision by Austrian researchers where it uses a camera to scan for pedestrians.
When it detects that there are pedestrians standing in the “right” position that indicates their intention to cross, it will then send a signal to the traffic lights. According to the researchers, they claim that this method is actually about 3-4 seconds faster compared to if pedestrians were to reach for a button.
In addition to being able to scan for pedestrians, it also helps create a dynamic system where if it detects an abnormally large group of pedestrians attempting to cross, it could extend the duration of the greenlight to allow more pedestrians to cross the street. There are plans to begin rolling out this system over in Vienna by a company called Günther Pincher.
