A point spatial object that is used to break up the road network for connectivity. The road network splits for the following circumstances:
The location where an attribute recorded on the road link changes for example its name or form.
The intersection or crossing of Roads (including bridges, flyovers and tunnels where there is no connectivity).
The start/end of a Road.
Where a One-Way Routing feature starts or ends.
Where a tunnel starts or ends.
Where there is a connection to the Path Network.
The context diagram below shows how the RoadNode has been inherited from INSPIRE and the attribution held on the RoadNode.
A point representing either the start/end of a road, the connectivity between two or more roads or where one of the recorded attributes changes along a road.

This section describes the features which make up OS MasterMap Highways Network - Roads. The attributes associated with these feature types are listed below along with a brief description of their data properties.
Many of the attributes which have been inherited from the INSPIRE Transport Network model have a stereotype of ‘voidable’, for example, “beginLifespanVersion”. Where these attributes have not been populated then there is a requirement to give a reason for this. This will be specified in the GML through an attribute called “nilReason”.
A FerryLink is a linear spatial object which represents the connectivity of a vehicular ferry route across a body of water. A FerryLink will only be captured where both terminals are within Great Britain, and there is a timetabled service which is available to the public. Ferry routes with a terminal outside of Great Britain are not captured, for example Dover to Calais, or where the service is not available to the public.
The context diagram shows how the FerryLink has been inherited from INSPIRE, the attribution held on the FerryLink and how it relates to the other Ferry components.

A Road feature is a link set which represents a collection of RoadLink features used primarily by motorised vehicles that share the same name (e.g. Bilston Road) or classification number (e.g. A41). A Road will reference the complete collection of RoadLink features irrespective of which authority boundary it falls within. The feature will include Motorways, A Roads, B Roads and Named Thoroughfares (roads), as illustrated above.
The link set may not be contiguous across junctions or where a classified road consists of separate sections, which may be separated by some considerable distance. In addition, the same RoadLink feature may be referenced by multiple Road features.
The context diagram shows how the Road has been inherited from INSPIRE and the attribution held on the Road.

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).
In the definitions below, users should read the term Highways as Roads when applied to streets in Scotland.
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.

A RoadLink is a linear spatial object that defines the geometry and connectivity of a road network between two points in the network. Road links can represent single carriageways, dual carriageways, slip roads, roundabouts and indicative trajectories across traffic squares. RoadLinks will be split for connectivity purposes (for example at junctions) and RoadNodes will connect the RoadLinks together. Each RoadLink will provide a reference to the RoadNodes at the start and end of the RoadLink.
RoadLinks will split where two links cross over or under one another when there is no connectivity, for example at bridges and flyovers. Therefore, the attributes “startGradeSeparation” and “endGradeSeparation” have been populated on the RoadLink. The Grade Separation attribute will indicate where there is or is not a physical connection between the roads in the real world. Grade Separation will determine if a RoadLink is above another; if the two RoadLinks, when referencing the same RoadNode, have different values then it is not possible to move between them at that point.
Where a RoadLink crosses a PathLink at a different level, both the RoadLink and PathLink will split. The attributes “startGradeSeparation” and “endGradeSeparation” will be populated on the RoadLink and PathLink. The Grade Separation attribute will indicate where there is or is not a physical connection between the road and path in the real world. Where the two links cross, the Road Node and Path Node will have the same identifier. Grade Separation will determine if one link is above another. If the two links, when referencing a Road Node and Path Node with the same TOID, have different grade separation values then it is not possible to move between them at that point.
The context diagram shows how the RoadLink has been inherited from INSPIRE and the attribution held on the RoadLink.
