Kier are the managing agent contractor for Area 3 responsible for Network management and maintenance on behalf of Highways England. Within their contract they are responsible for a range of asset management surveys, including the reflectivity performance / condition of road signs. This survey information in turn informs the development of maintenance and renewal schemes.
The survey vehicle has the capability to survey road signs at road speed (up to 70 mph on motorways), measuring the retro-reflectivity of the sign background, it’s legend, it’s gps position, and the sign dimensions and height above the carriageway. In effect, collecting a full asset inventory of the signs. The AMAC system operates at night, enabling real world accurate data recording, with reduced traffic disruption, and no requirement for traffic management.
