Traffic Control Devices
Traffic control devices are used to control, calm, slow or impede the movement of traffic. They include roundabouts, gates, stock grids, level crossings, tolls and barriers
Traffic control devices are markers, signs, signal devices, marking, light or device, installed on a road. Used to inform and guide traffic control including pedestrians, bicyclist and motorist
- 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
- predicting, analysing and modelling traffic flows, accidents, when joined with business or statistical information - 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 authorities
- identification of infrastructure vulnerable to different hazards
- identification of controls on livestock during pandemics (gates and stock grids only)
- Service provision
- funding determinations for infrastructure investment
Standards and Specifications
Access and Licensing
Access and Licensing Details
- Only includes data from Victoria and Tasmania
- No Fixed speed camera or pedestrian crossing information included.
- Accuracy of data varies from:
- Approximately 2m in metropolitan areas. Does not include light rail networks in urban 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
In each jurisdiction, the land management or mapping agency creates and manages datasets representing the location of a traffic control device, which may be integrated from data held by transport authorities, or derived from GPS data, previous mapping, or from interpretation from satellite- or airborne imagery.
Data captured under Commonwealth mapping programs has not integrated with state and territory datasets.
There is currently no single vertical integration of all transport datasets, as listed, for the national coverage.
- Dataset custodianship will sit with the relevant state and territory land management authority.
- National custodianship of the national dataset needs to be identified significant stakeholders include:
- Department of Infrastructure and Regional Development, as the lead Australian Government agency on transport and regional affairs
- Geoscience Australia, due to its role as the national mapping authority and its close collaboration with state and territory agencies in maintaining all topographic information, its role in maintaining information on exposure of infrastructure to hazards, and its underpinning role in providing spatial advice to other parts of Australian Government.
- The National Topographic Information Coordination Initiative will continue to address consistency issues in dataset content, and compliance with the ICSM Roads Data Model, by:
- Integrating the GEODATA Topo-250K data content into datasets managed by the states and territories, with subsequent aggregation by PSMA Australia
- National information products will be made available as web services.
- Provide a nationally consistent roads dataset which supports and delivers transport information through the vertical and horizontal integration of the listed datasets. This will allow linking of location of these features across all themes.
- Traffic control device information included in national topographic mapping products will be derived from the datasets in states and territories
- Data held by transport authorities which is categorised as part of the foundation will be integrated with the foundation datasets.
- Traffic control devices will be captured no worse than 1m in urban areas and between 2m and 10m in remote areas if captured from imagery.
- National information products will have near-real-time currency.
- All national information products will be available under open access arrangements (for example, by CCBY) at zero cost.
- Be expanded to include pedestrian crossing, traffic lights and fixed speed cameras.
