Signal 1: Digital Traffic Wall Concept
The new digital traffic wall concept comes from LuminoCoin and is assumed to launch at around 2020 in all over the Asian countries. This concept allows highly visible hologram system which is seen without the aid of special glasses or other intermediate optics. The less visible lights of standard three-light system usually do little to catch the attention of motorist who are not focus on the road. With the digital traffic wall, drivers and pedestrians can be influenced psychologically by the optical barrier to avoid red light running.
The principle of holographic virtual wall is based on a laser projector that projects the images of moving pedestrians visible only to the drivers in front of it. If this new wave of technology can be widely used then there will have the huge effects on all fields of life including education, business and science.
But this new concept is still being questioned. For instance, the red virtual wall may cause the visual obstruction for pedestrians when ambulances and fire engines passing by. In this case, the digital wall should have a sensor device to detect the coming ambulances and turn the wall off automatically.
