The idea of using a laser instead of the traffic offered to the wall designer Hanyoung Lee. The virtual wall is planned to show three-dimensional images of pedestrians, which is formed by lasers. This wall will be perfectly visible in all weather conditions, which sometimes can not be said about the traffic lights faded, which is why sometimes there are assaults on pedestrians and accidents.
There is a huge plus for such a wall, because the drivers will be psychologically difficult to move a virtual pedestrian.
When you are running this innovation in the production and put into practice as yet unknown.
