This layer comprises road centrelines for all roads controlled by Main Roads (State Roads) and all roads controlled by Local Government (Local Roads) that are assigned road numbers in the state of Western Australia. Other centreline is also included for paths and unknown roads. The Road Network are attributed with a road number as identified in Main Roads’ corporate Integrated Road Information System (IRIS) and the local government Road Management database (ROMAN). The purpose of this layer is to identify roads as identified in IRIS. This data presents the road network in Western Australia as of August 2018.

Layer of Structures (road and pedestrian bridges, rail bridges, sign gantries and tunnels), in Western Australia. This layer provides general inventory information for all Structures on State roads, Local roads or Department of Environment and Conservation (DEC) roads. A road structure is that portion of the carriageway that carries vehicular, pedestrian, and bicycle traffic over or under an obstruction such as a watercourse, another road or railway line.

This dataset presents the location of electronic traffic signals, designed, owned and or controlled and maintained by Main Roads Western Australia, that control vehicle and pedestrian traffic at an intersection or on a road are identified in this data set. The signal can be red, yellow, green or white light displays, and can include circular and arrow signals, pedestrian signals, bicycle crossing signals, B (bus) signals, overhead lane control signals, and twin red or yellow signals. This dataset was developed to identify the location of Main Roads' controlled electronic signals across Western Australia and assist in the management of this asset. Additionally, it records attribute information which includes the LM No (Asset ID.), Service Status, Signal Type, Intersection Name and Intersection Description. This data presents the traffic signal sites of Western Australia as of June 2018. AURIN took the data in August 2018. For more information please visit the MRWA Open Data Portal.

This layer shows intersections on the road network stored in the Integrated Road Information System (IRIS). An intersection is a road junction where two or more roads either meet or cross at grade (they are at the same level). The layer also details the IRIS Intersection Number. This data presents the intersections in Western Australia as of December 2017 and AURIN took the data in August 2018. For more information please visit the MRWA Open Data Portal.

This document contains maps of roads identified as State Road or part Regional Road, under the administrative agreements with Local Government. These roads are also legally classified as Freeway, Tollway, State Highway, Main Road or Tourist Road under the Roads Act 1993. A summary listing is also included.

Special Use roads are public roads administered by Local Governments, which have a separate use in addition to their typical Road Hierarchy function. Categories of Special Use roads include Aboriginal Access Roads, Industrial Roads and Laneways. Aboriginal Access Roads typically are the main access roads to Aboriginal communities; Industrial Roads are found in designated industrial areas, and Laneways are typically short narrow roads providing access to residential areas.
