Researchers at the Fraunhofer Institute for Physical Measurement Techniques have come up with a car-mounted laser scanner the size of a shoe box, that can survey the contours of road surfaces at speeds of up to 100 km/h (62 mph). The system detects potholes and other road damage in need of repair. According to the Institute, the Pavement Profile Scanner (or PPS) has surveyed 15,000 km of road since mid-2012, in which time it has proven cheaper, faster and more accurate than existing systems which require hefty attachments to the carrier vehicle.
