Routes

Each state and territory has its own system for allocating route numbers. Many states have moved to the newer, "alphanumeric" numbering system for route allocation. Other states are still in the process of transitioning to the new system, or haven't started transitioning at all, and continue to use the "old style" numeric routes. Both route types of route numbers should be documented with the ref=* and network=* tags

Network tags

The network=* tag should be used to identify the state or territory in which a road is located, while the ref=* tag should contain the route number. For alphanumeric route numbers, the ref=* should include the route letter prefix.

Route Tagging

Alpha-numeric routes						Numeric Routes
M M1	A A1	B B10	C C123	D D1	R R1	National Route	Alt National Route	National Highway	State Route	Tourist Route
ref=route number network=AU:S/T						ref=route number network=AU:S/T:NR	ref=route number network=AU:S/T:ALT_NR	ref=route number network=AU:S/T:NH	ref=route number network=AU:S/T:S	ref=route number network=AU:S/T:T
ref=C123 network=AU:VIC Example of an alphanumeric route: C123 (C123 C123) in Victoria						ref=116 network=AU:WA:S Example of a numeric route: (State Route 116 State Route 116) in Western Australia

Route and Highway Relations

A illustrative example of how a route reference, highway name and street name can vary. This would be correctly mapped with one relation for the route number (C413), and another for the "Blue Highway".

Each route number should have its own route=road relation consisting of each constituent road.

ref=B45
type=route
route=road
network=AU:SA

Example of a route relation: B45 B45 in South Australia, consisting of Ferry Road, Langhorne Creek Road, Wellington Road, Bridge Road, and Wellington-Strathalbyn Road.

Many named routes and highways will be known by different names as they pass through towns and cities; most famously the Princes Highway. These major routes should also be given their own, separate, relation.

name=Pacific Motorway
type=route
route=road
network=AU:QLD

Example of a route relation: Pacific Motorway Pacific Motorway between Gold Coast and Brisbane, It itself is one part of the larger M1 route.

Interstate Routes

When a route crosses a state boundary, the route relation should be split into multiple single state routes and added to a "national" super-relation.

ref=B12
type=superroute
route=road
network=AU

Example of a route relation: B12 B12 between Tailem Bend, South Australia and Tooleybuc. It's members are B12 (SA) B12 (SA) and B12 (VIC) B12 (VIC).
