The Austroads Road Asset Data Standard provides road agencies and their suppliers in Australia and New Zealand with a specification for the data that supports common operational activities.

The Data Standard also provides road network funding agencies with a specification to inform structure of reports and submissions requested from road agencies, to enable more equitable evidence‑based investment decision-making. Specifically, the Standard establishes a common understanding of the meaning or semantics of the data to ensure appropriate use and interpretation of the data by its stakeholders.

The Standard also provides information on Priority Data Sets that can support harmonisation activities for both local and state road managers. Accordingly, the Standard will benefit any road industry stakeholder who utilises data for road research, policy development, expenditure comparisons, funding approvals, supporting national reforms, national reporting, innovation, shared services, and inter-organisation communications.

The Austroads Road Asset Data Standard is available in three machine readable formats:

  • Comma Separated Value (CSV)
  • JavaScript Object Notation (JSON)
  • Extensible Markup Language (XML).

Download a zipped folder (8.4 MB) containing the PDF version and machine readable versions with instructions.
