The Road and Path Networks are topologically structured together. Connecting Links have been introduced to enable a connection between the Road Network and the Path Network. A Connecting Link feature is a linear spatial object which represents a logical connection between the Path Network and the Road Network, and they do not represent a feature in the real world. A Connecting Link will always reference a Path Node and a Connecting Node.
The earliest date on which you can request a one-off snapshot of a date in the past for data in this feature type is 29 September 2022.
The following sub-sections provide details about the attributes included with this feature type, their data types in the different output formats, and other important metadata about them.
Primary identifier for the feature. The OSID is a Globally Unique Identifier (GUID) and requires no centralised authority to ensure uniqueness. Note that the same OSID can occur in more than one feature type when a single feature is represented multiple times in the OS NGD.

A Connecting Node is a point feature that identifies the point along the Road Link which the Path Link connects to. The Connecting Node connects to the start or end of one or more Road Links and provides a reference to one of the Road Links it connects to. Connecting Nodes are spatially coincident with Road Nodes and can share the same identifier. The Connecting Node is referenced by a Connecting Link.

A Ferry Link is a linear spatial object which represents the connectivity of a vehicular ferry route across a body of water. A Ferry Link will only be captured where both terminals are located within Great Britain and where there is a timetabled service which is available to the public. Ferry routes with a terminal located outside of Great Britain are not captured (for example, Dover to Calais) and neither are ferry routes where the service is not available to the public.

The OS NGD Transport Network Collection provides a topologically structured link and node representation of Great Britain's road, ferry, rail and path networks. This collection provides information on road classification; road and path function; primary routes; road node classification; names associated with the road and path networks; path surface type, and connectivity between the road network and the ferry, rail, and path networks.
In September 2023, a rail network was added to the OS NGD Transport Network Collection with the addition of the three feature types: Railway Link, Railway Link Set, and Railway Node. Furthermore, the presence of pavements on the road network was supplied against Road Link features, and the Pavement Link Feature Type was also added to the collection.
From March 2024, tram track attribution indicating the presence of tram tracks on a road has been supplied against Road Link features, and the Tram On Road Feature Type was added to the collection.
Images showing the feature types available in the collection are shown below:
The OS NGD Transport Network Collection allows you to:
Ensure your transport data is always up to date with monthly updates.
Identify the authority responsible for naming, numbering and maintaining a street.
View ferry routes which start and end in Great Britain.
Create statistics for evidence-based policy making, such as school transport allocation, funding distribution and meeting sustainable transport policies.
Visualise the connectivity between the road network and path network.
Examine the surface type, function and names associated with paths.
Visualise a simplified topographic representation of rail networks across Great Britain, thereby providing better understanding of connectivity for passengers and freight.
Identify Road Links which have pavements associated with them and visualise the extent of pavements on the road network.
Identify Road Links which have a tram track on them and visualise the extent of tram tracks on the road network.
Monthly updates to data.
Plug and play – the data is simple and quick to implement as you don't need to pre-process it before you use it.
Rich attribution ensures the data is straightforward to navigate and query.
Simplified attribute naming helps make names easier to understand.
Persistent unique identifiers with lifecycle information.
New cross-references make it easy for you to link data in this collection with data from other OS NGD collections.
Geometry available for every feature.
Great Britain.
British National Grid + ODN Height (EPSG: 7405) for most feature types in the collection; British National Grid (EPSG: 27700) for the Ferry Terminal, Path, Road, Road Junction, Street and Pavement Link Feature Types.

The Ferry and Road Network elements are linked together through a Ferry Terminal feature. A Ferry Terminal is a logical connection between the two networks, and therefore there is no geometry supplied with these features. They will reference one Road Node and one Ferry Node. The Ferry Terminals will also provide a reference to the related Site representation of the same Ferry Terminal.
The earliest date on which you can request a one-off snapshot of a date in the past for data in this feature type is 29 September 2022.

A Path Link is a linear spatial object that defines the geometry and connectivity of the Path Network between two points in the network. Path Links will be split for connectivity purposes (for example, at junctions) and Path Nodes will connect the Path Links together. Each Path Link will provide a reference to the Path Nodes at the start and end of the Path Link.
Path Links will be captured where:
They provide a route that cannot be inferred from the Road Network
They provide connectivity between Road Networks
There is a canal path or tow path
There are paths over footbridges and under subways
Path Links will not be captured where:
They run parallel to the Road Network (for example, a pavement)
They are connected to a motorway
There is a physical obstruction which prevents connectivity
They are non-public paths (for example, in a school, prison, or military area)
They do not meet validation criteria in place to maintain network quality (for example, isolated links with no connectivity to another link)
The earliest date on which you can request a one-off snapshot of a date in the past for data in this feature type is 29 September 2022.

A Road feature is a link set which represents a collection of Road Link features that share the same name (for example, Bilston Road) or classification number (for example, A41), used primarily by motorised vehicles. A road will reference the complete collection of Road Link features, irrespective of which authority boundary it falls within. The feature type will include Motorways, A Roads, B Roads, and Named Thoroughfares (roads).
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 Road Link feature may be referenced by multiple Road features.
The earliest date on which you can request a one-off snapshot of a date in the past for data in this feature type is 29 September 2022.

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 feature
Where a one-way routing feature starts or ends
Where a tunnel starts or ends
Change of local highway authority
Where there is a connection to the Path Network
As part of a data enhancement programme in late Spring 2023, we have now captured what were previously Site Routing Point features as Road Node features. This means that there are now additional Road Node features contained within this feature type. These additional nodes make it even easier to create a routable network which considers access to Site features.
The earliest date on which you can request a one-off snapshot of a date in the past for data in this feature type is 29 September 2022.
The following sub-sections provide details about the attributes included with this feature type, their data types in the different output formats, and other important metadata about them.

A Road Link 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. Road Links will be split for connectivity purposes (for example, at junctions) and Road Nodes will connect the Road Links together. Each Road Link will provide a reference to the Road Nodes at the start and end of the Road Link.
