MetRoad - Road Condition with Laser Backscattering
MetRoad is a laser sensor for monitoring road condition such as dry, wet, icy and snowy and estimating the friction between the road and the wheels of vehicle. The MetRoad uses patented technology for non intrusive monitoring of the road surface. Information from MetRoad can be used to warn a driver of low road friction or hazardous road conditions, or sent to a central location for implementation into maintenance decision support systems. The working principle is spectral analysis of backscattered laser.
