This dataset presents a description of the hierarchy role performed by different parts of the road network. It also provides criteria to describe each road role type. The role type designated to each road should represent the role that the road is intended to perform. It may not necessarily reflect the current conditions on the road. A total of six hierarchy types are used for roads in Western Australia. The Road Hierarchy provides a high level description of the hierarchy performed by roads in the network across WA. Road management is guided by the hierarchy type of each road.
This data presents the road hierarchy in Western Australia as of December 2017. AURIN took the data in August 2018.
