This national harmonised dataset uses daily updates from State and Territory roadworks endpoints (APIs) to build a nationally consistent, harmonised historic database of roadworks and road closures over time across all of Australia. By doing the work of collecting and harmonising data to the national level, the NFDH generates efficiencies and saves multiple stakeholders' resources doing the same data collection and harmonisation work for different systems and projects. For example, this data set could be used to understand (and potentially predict and manage) road damage and road closures and improve resilience in the context of natural disasters or disruptions. The following visualisation illustrates the roadworks and road closure information contained in this dataset.
