RoadClassificationValue

Road classification is used by government to ensure that there is a feasible, logical road network throughout the country. Road classifications are set to take into account the traffic management goals and road categorisation approach of the Local Highway Authority (LHA) in England and Wales. Currently, in Scotland only Motorway A Road and B Road classifications are provided.

RoadLink, Road and Street features are attributed with a “roadClassification” with a data type of “RoadClassificationValue”. The table below describes the codes which will be used to populate this field and the description for each code.

Code	Description
Motorway	A multi-carriageway public road connecting important cities.
A Road	A major road intended to provide large-scale transport links within or between areas.
B Road	A road intended to connect different areas, and to feed traffic between A roads and smaller roads on the network.
Classified Unnumbered	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.
Unclassified	Roads intended for local traffic. NOTE 1: These may be designated Unofficial local road classifications. For example: D, E, F and G roads.
Not Classified	Roads that have not been assigned a road classification at national or local level by a designation authority.
Unknown	The classification of the road is unknown because the RoadLink is not a Motorway, A or B road and the RoadLink has not been matched to the National Street Gazetteer.
