The Road dataset is an aggregation of data from multiple jurisdiction sources which depicts national and accurate road based information.
Classification depending upon its purpose or importance, such as a national highway that connects capital cities, arterial roads which connect major regional centres or move large volumes of traffic across metropolitan areas, down to access roads which provide access to buildings within properties centrelines.
- Routeing, traffic flow management and economic analysis
- the development of routeing road networks for use by freight and logistics companies, emergency service / response authorities, and general public includes: shortest distance, fastest time and presence/absence of obstacles or restrictions depending upon mode of transport - name, structure, weight/height/speed limits or some other weighting
- fuel-efficient fleet management and self-drive vehicles - require full transport surface specifications including slope, camber, etc.
- predicting, analysing and modelling passenger and freight vehicle movements, and accidents, when joined with business or statistical information for analysis. May only need a list by name, but possibly also location and intersection with other roads, railways, crossings etc.
- Context for other location information
- context for other features over local or small project areas - may show location, name, surface and user access
- context for other features on topographic maps, or other regional or national tourist maps - usually name, class, surface, and route number, obstacles or barriers
- context for charts and reference maps - generally only the location of higher order roads shown
- Asset management, infrastructure protection and public safety
- asset management systems by roads authorities
- identification of infrastructure vulnerable to different hazards
- Service provision
- Being able to calculate the remoteness of communities by comparing a location to the nearest urban centres, particularly to identify areas poorly served by medical facilities
- funding determinations for infrastructure investment
- Analysis of other foundation datasets to determine
- unique addresses within a locality and its neighbours
- the location (as a boundary or an important artery) of administrative boundaries such as local government areas, localities and statistical geographies

Access and Licensing Details
- The roads component of this dataset conforms to the Intergovernmental Committee on Surveying & Mapping's roads data model and PSMA's business rules for this product
- Accuracy of data varies from:
- Approximately 2m in metropolitan areas
- 10–20m in urban fringe and rural areas
- 50–150m in remote areas. There are breaks in connectivity at state borders
Data is six months old when released to market but in rural and remote areas features have a currency of 5–20 years
- Information is available that describes:
- Type of road
- User access and physical restrictions
This information is at various levels of completeness depending upon the jurisdiction. Information may also not be consistently classified between states and territories – for example, an arterial road in one state may not be the same as an arterial road in another
- The product is GIS-ready in a range of formats depending upon the distributor
