RoadJunction
A RoadJunction feature is a collection of RoadNode features that share the same road junction name or number. The collection of RoadNodes will include all RoadNodes that constitute part of a “slip road” or other link between two or more crossing road features. A RoadNode could be referenced by multiple RoadJuntion features.
Motorway Junctions will be populated completely, other junctions are being supplied as data is improved for future releases. Highlighted red for clarification only.

The context diagram below shows how the RoadJunction feature relates back to the Network Elements.

RoadJunction Attributes
