LinkReference

When a feature occurs along a complete single RoadLink, a Link Reference will be used. Geometry is not provided for these features. The direction along the RoadLink for which the feature applies is supplied through the applicableDirection. If the feature applies to the RoadLink, regardless of which direction you travel along it (for example, Traffic Calming), then the value will be both directions. If the feature applies to the RoadLink in a specific direction of travel (for example, a One-Way road), the direction will be given in relation to the digitisation of the RoadLink (the order of coordinates).

The feature types which use a Link Reference are TurnRestriction and Structure.
