The RoadLink feature is attributed with a “routeHierarchy” with a data type of “RoadFunctionValue”. The table below describes the codes used to populate this field and the description for each code. In addition, INSPIRE provides an attribute “Functional Road Class” which identifies the importance of the role that the road performs in the road network. Therefore, these values have been mapped to the INSPIRE values.
