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 layer shows the location of Structures on all public access roads in Western Australia and is provided for information only.Note that you are accessing this data pursuant to a Creative Commons (Attribution) Licence which has a disclaimer of warranties and limitation of liability.

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.

This layer shows the location of regulatory signs & Main Roads Western Australia is the responsible authority. The term regulatory sign describes a range of signs that are used to indicate or reinforce traffic laws, regulations or requirements which apply either at all times or at specified times or places upon a street or highway, the disregard of which may constitute a violation. One type of regulatory signs are stop signs or give way signs, intended to instruct road users on what they must or should do (or not do) under a given set of circumstances. Signs can be on the State Road Network or other public access roads and is provided for information only.Note that you are accessing this data pursuant to a Creative Commons (Attribution) Licence which has a disclaimer of warranties and limitation of liability.

This layer indicates the location of culverts managed and controlled by Main Roads Western Australia. A culvert is a drain or pipe that allows water to flow under a road, railroad, trail, or similar obstruction. Culverts differ from bridges mainly in size and construction.Note that you are accessing this data pursuant to a Creative Commons (Attribution) Licence which has a disclaimer of warranties and limitation of liability.

Focal Point Markers are signs placed on the left side of the road and read in the direction of travel. Focal Point Markers provides road users with a distance to larger town centres, roadhouses or well known features along roads in remote localities.This layer indicates the location of Focal Point Markers on the State Road Network and is provided for information only.Note that you are accessing this data pursuant to a Creative Commons (Attribution) Licence which has a disclaimer of warranties and limitation of liability.

This layer indicates the administrative boundaries of all Main Roads Regions. \nMain Roads Regions do not necessarily align themselves to other Western \nAustralian State Government Management Regions, but each region has a Main Roads \nregional presence with an office in the major regional centre. In Western \nAustralia, each Local Government is grouped into a Main Roads Region.

SLKs or Straight Line Kilometers are a location reference system used by Main Roads Western Australia to define the location of features or events along a road. This layer shows SLK points (every 100m) along the left and single carriageways for all State and Local Roads, Main Roads controlled paths contained within the road centreline of Main Roads road asset database. The purpose of this layer is to identify and label the measure of SLK along a particular route and is provided for information only. The SLK points are based on geometric measure and include points of equation. This means that you may notice “jumps” in the SLK between two points that are not equal to 100m. This is as a result of network changes that have been incorporated into the spatial road centr eline.A point of equation is a business term used to describe a point on the road network, which has two SLK references, one for the section leading up to it, and one for the section leaving from it. A Point of Equation is either: •A gap, which occurs when the new deviation/realignment is built shorter than the existing road. An SLK range is missing. •An overlap, which occurs when the new deviation/realignment is built longer than the existing road. An SLK range is duplicatedNote that you are accessing this data pursuant to a Creative Commons (Attribution) Licence, which has a disclaimer of warranties and limitation of liability.

The pavement is that portion of the carriageway placed above the subgrade for the support of, and to form a running surface for, vehicular traffic. It is comprised of the trafficable part of the carriageway (i.e. the traffic lanes), plus the sealed and unsealed portion of the shoulder. When a road is widened the definition of the pavement extends to include the widening. Pavement details are recorded for each carriageway and left and right shoulders of a road.Physical Model Note that you are accessing this data pursuant to a Creative Commons (Attribution) Licence which has a disclaimer of warranties and limitation of liability.
