Traffic lights have been the same now for thirty years. High time for an update, Dennis van Melick decided. He designed a completely new traffic regulation system based on Red Green Blue LEDs, which guides road users through traffic more safely than ever. “Three to One is more compact, more efficient, and boasts more features than current traffic lights,” explains Van Melick. Red is a square, orange a triangle and green a circle: colour-blindness is no longer a problem. With its clear signals the display can close a lane, create a bus lane, or signal ambulances, police cars and fire engines. An innovative suspension system makes installation easy and vandal-proof.
