Laser Beam Zebra Crossings

Hanyoung Lee from the Idas-Hongik University in South Korea developed a Virtual Wall that can be installed near traffic lights or zebra crossings. The Virtual Wall is a warning signal that uses harmless plasma laser beams to create an image of a wall with people crossing. The message is powerful and eye-catching enough to alert inattentive drivers that pedestrians are in the crosswalk. In 2008 Lee won the iF Concept Award for his innovative concept that could save thousands of lives a year nationwide.
