State Road Access Control Areas in Western Australia

Control of Access identifies sections of state roads where direct vehicle and pedestrian access from adjacent land is legally restricted by Main Roads Western Australia. This spatial dataset covers all State Roads, with ramps universally under control but potentially not displayed. The data is maintained by the Commissioner of Main Roads and shared under a Creative Commons Attribution license.

Use Cases

• Map declared Control of Access zones on State Roads to analyze road safety and traffic flow management.
• Identify road segments where adjoining land rights are revoked for direct access to support urban planning.
• Integrate with other road network layers to assess infrastructure connectivity and access point regulations.

Strengths

• Authoritative source from Main Roads Western Australia, the statutory road authority.
• Available in multiple geospatial formats including GeoJSON, KML, and CSV for diverse tool compatibility.
• Explicitly covers all State Roads within the jurisdiction.

Limitations

• Sample data and specific row/column counts are unavailable, limiting pre-download assessment of structure.
• The layer may not fully display all State Road ramps, despite them having declared Control of Access.
• Data is subject to changes per the license disclaimer, requiring users to verify currentness.
