Roads classification exists to ensure that there is a feasible, logical road network throughout the country. Roads classifications should be set to take into account the traffic management goals and road categorisation approach of the Local Highway Authority (LHA). RoadClassificationValue A multi-carriageway public road connecting important cities, classified by the DfT. A Motorway does not form part of the official Road Classification scheme as it is a Special Road. However it has been included to allow them to be classified. Motorway A major road intended to provide large-scale transport links within or between areas. A Road A road intended to connect different areas, and to feed traffic between A roads and smaller roads on the network. B Road Smaller roads intended to connect together unclassified roads with A and B roads, and often linking a housing estate or a village to the rest of the network. NOTE 1: A Street may be assigned a local classification number by the Local Highways Authority. Classified Unnumbered Roads intended for local traffic. NOTE 1: These may be designed Unofficial local road classifications. For example: D, E, F and G roads. Unclassified Roads that have not been assigned a road classification at national or local level by a designation authority. Not Classified The classification of the road is unknown, this is either because the RoadLink is not a Motorway, A or B road and another classification has not been recorded in the National Street Gazetteer or because the RoadLink is not a Motorway, A or B road and the RoadLink that has not been matched to the National Street Gazetteer.
