A Street feature is the definition of the street as defined in the National or Scottish Street Gazetteer. A Street includes aggregated geometry. Where possible, the geometry of streets captured by a Roads or Highway Authority is spatially matched to the geometry of OS RoadLinks.
If any of the Street’s Elementary Street Unit(s) (ESUs) have been matched to a RoadLink(s) then the aggregated geometry of the RoadLink(s) will be provided.
If none of the Street’s ESUs have been matched to a RoadLink then the aggregated geometry of the ESUs will be provided.
The provenance of this geometry can be identified through the “geometryProvenance” attribute. They will represent either the complete Street or a section of a Street within an Administrative Unit, Town, or Locality and provides additional information about who is responsible for its naming and or numbering. A RoadLink can be referenced by multiple Street features.
The Street extends the Road to provide the additional attribution required to adhere to BS 7666:
USRN: The Unique Street Reference Number is the unique and persistent identifier of a Street assigned by the Roads or Highway Authority.
Street Type: The type of Gazetteer record for which the USRN relates. It is mandatory for all USRNs to be assigned a Street Type.
Operational State: indicates whether the Street is proposed, under construction, open, or closed (permanently or temporarily).
Responsible Authority: reference to the authority who performs an administrative function – notably naming and numbering.
A Street will split when it crosses the boundary of an Administrative Area where the local maintenance responsibility changes. A Street could also split at a town or locality boundary to allow properties to be located uniquely upon a street via a unique identifier (i.e. USRN).
Any road, footway, path, cycletrack, track or passageway that forms a highway. A highway represents individual subsections of Road which are managed (naming/numbering) by a specified responsible authority.
Constraints: A Street shall have at least one of designatedName (Type 1), descriptor (Type 2), nationalRoadCode (Type 3), localRoadCode (Type 3), or localName (Type 4). If a Street has a descriptor, it shall not have a designatedName. If geometryProvenance does not = "Ordnance Survey" then 'link' shall be null. If the roadClassification = "Motorway" or "A Road" or "B Road" then the nationalRoadCode shall not be null.
