ROTAFLECTOR fits securely on the top of traffic cones and can replace up to 50% of road danger lamps (every other lamp) in straight line delineation, claims its manufacturer. The wind-driven rotating reflective device has been fully tested at TRL [UK's Transport Research Laboratory] and approved for use on the network by the UK Highways Agency and the Department for Transport. Requiring no batteries, the ROTAFLECTOR is made from recycled materials and is totally recyclable itself.

INO, a world-class centre of expertise in industrial applications for optics and photonics, offers its laser rut easurement system (LRMS), a transverse profiling device that detects and characterises pavement rutting. The organisation says LRMS can acquire full 4m width profiles of a highway lane at normal traffic speeds (up to 100km/hr), using two laser profilers that digitise transverse sections of the pavement.
