Major Highways And Arterial Roads Of Australia

Australia's land mass and offshore islands are covered by this geospatial dataset representing highways, arterial, and sub-arterial roads. The dataset provides an aggregated national view of road geometry and attribution, created from multiple jurisdictional sources. It excludes railways, tramways, driveways, and passenger ferry routes.

Use Cases

• Analyze road geometry for national transportation network planning and infrastructure assessment
• Map highway and arterial road attribution to support regional connectivity studies
• Integrate jurisdictional road data into a unified national geospatial database for cross-regional analysis

Strengths

• National coverage includes the entire Australian land mass and offshore islands
• Aggregated view consolidates road data from multiple jurisdictional sources
• Focus on major transportation routes (highways, arterial, sub-arterial) provides a filtered subset for core network analysis

Limitations

• Excludes railways, tramways, driveways, and passenger ferry routes, limiting multimodal transport analysis
• Data quality varies as source jurisdictional data is supplied in different formats and at different levels
• Norfolk Island is currently not included in the geographic coverage
