Road Class Matrix

Road Authorities currently use a confusing array of road hierarchies to group roads.

The table below is an attempt to make sense of the confusion, and to compare the road classes used in different hierarchies.
Many of the criteria listed, are based on those used in developing the Perth Metropolitan Road Hierarchy.
