Western Australia Restricted Heavy Vehicle Road Network

Western Australia's Tri Drive Network 3.2 dataset details roads with conditions for restricted heavy vehicle access. The Commissioner of Main Roads creates and owns this data, which is updated weekly. Users must confirm information is current via the official Main Roads WA website.

Use Cases

• Map permissible routes for Tri Drive Concessional Level 2 vehicles using road condition attributes
• Analyze spatial coverage of HVS networks across Western Australia for infrastructure planning
• Integrate road table data with the RAV Mapping Tool for visual route validation

Strengths

• Weekly update frequency ensures regular data refresh
• Spatial coverage is explicitly defined for Western Australia
• Provided in multiple formats including GEOJSON, CSV, and KML for interoperability

Limitations

• Specific row counts, column names, and sample data are unavailable for assessing dataset scale and structure
• Users bear responsibility for verifying data currency against the official source, introducing a manual validation step
