Buoyancy-Road Buoyant Lane Separator Concept by Joh Minhoo is a buoyant lane separator. If the road is covered with water or snow over the height of the traffic lane, Buoyancy-Road emerges due to its buoyant quality. This enables drivers to recognise the position of the lane markings. The system can also be manually activated in the case of a temporary lane reversal.
