Data Description:

Abstract Major Roads is a subset of the National Roads dataset, filtered for highways, arterial and sub-arterial roads. National Roads is a digital representation of the road network of Australia. National Roads contains linear features to describe surfaces that have been improved to enable vehicular, pedestrian and bicycle transportation on land and ferry routes that enable vehicles to cross water bodies. National Roads does not include railways, tramways, driveways or passenger ferry routes. This dataset provides an optimised aggregated national view of road geometry and attribution. The dataset is created from multiple sources including jurisdictional data which is revised regularly and supplied in varying formats and at different levels of quality. The purpose of Roads is to provide a single national digital representation of Australian roads with detailed attribution to enable clients to undertake activities including visualisation, analysis and logistics planning at both a national and local scale. The area covers the land mass of Australia, including offshore islands. Norfolk Island is currently not included. Currency Date modified: February 2024 Modification frequency: Monthly Data Extent Spatial Extent West: 96° South: -44° East: 160° North: -9° Source Information The data was obtained from Geoscape Australia. Geoscience Australia is providing this data to the public under a Creative Commons Attribution 4.0 license. Geoscience Australia catalog entry: Major Roads Lineage Statement National Roads provides a single national digital view of road centrelines across the entirety of Australia. Roads is continuously built through sourcing a broad range of datasets from many organisations. This data is quality assured, standardised, integrated and topology-corrected before publication. Road centrelines are primarily sourced from State and Territory governments and form the basis for the Roads network. Roads additional to the State and Territory provisions are digitised or integrated where reliable sources of road centrelines are identified that improves the quality and/or consistency of Roads nationally. For attribution of Roads data sources refer to this webpage: geoscape.com.au/legal/data-copyright-and-disclaimer/. The Digital Atlas of Australia team have published a feature layer for Major roads in GDA2020 format. Major roads is a filtered subset of the National roads dataset that have an operational status, and roads with a hierarchy value of National or State highway, arterial, or sub-arterial.

Attribute Name Description:

road_id Persistent identifier for a roads feature

contributor_id The contributor’s identifier for a Roads segment

jurisdictional_control The Jurisdiction with control of the road as defined by the source State or Territory Jurisdiction (e.g. TRANSPORT FOR NEW SOUTH WALES)

operator The operator of the road

date_created Date this record was created in the data custodian’s system. Where this date is not available, then the first date on which the feature was processed for inclusion within Roads

date_modified Date this record was last updated

national_route A route number to identify a route of National significance (e.g. C30)

state_route A route number to identify a route of State significance (e.g. A20)

full_street_name The full official road name, which is a concatenation of street_name, street_type, and street_suffix attributes (e.g. PARKES PLACE WEST)

street_name Name of the road (e.g. SMITH AND JOHN)

street_name_label Name of the road in Title Case (e.g. Smith and John)

street_type Type of road (e.g. ROAD, STREET, CIRCUIT, LANE)

street_type_label Type of road in Title Case (e.g. Road, Street)

street_suffix Suffix of road (e.g. WEST)

street_suffix_label Suffix of road in Title Case (e.g. West)

street_alias_name A secondary name of the road

street_alias_type A secondary type of the road

street_alias_suffix A secondary suffix of the road

feature_type The classification of a road according to its physical characteristics (e.g. MOTORWAY, SINGLE CARRIAGEWAY)

hierarchy Hierarchy of the road (e.g. NATIONAL OR STATE HIGHWAY)

subtype Physical type of a road (e.g. ROUNDABOUT)

ground_relationship The relationship the road has with the ground (e.g. ABOVE GROUND, ON GROUND, BELOW GROUND)

lane_count Number of physical lanes represented as a total count

lane_description Description of the physical lane count of a road

one_way Indicates if the road supports one-way or two-way traffic direction

status Lifecycle stage of a road (e.g. OPERATIONAL)

surface Surface of the road (e.g. SEALED)

trafficability Indicates the minimum type of vehicle advised to traverse the road (e.g. 2WD)

travel_direction Direction a vehicle is allowed to travel

speed Posted speed limit for the section of road to which it is attributed

state Indicates the State or Territory abbreviation of the jurisdiction its linear geometry predominantly intersects (e.g. NSW)

horizontal_accuracy The horizontal accuracy of the line feature in relation to the real-world location in metres
