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 |
|---|---|
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.
