Accident Blackspots on NSW Highways: 20,000 Crashes Over 2.5 Years

Approximately 20,000 crash locations on New South Wales State highways and freeways were mapped using the Australian Map Grid over a two and a half year period. The data identified 20 rural sites with high crash frequency, defined as 200-meter road segments. This report was produced by the NSW Government.

Use Cases

• Identify high-frequency crash locations based on geospatial coordinates mentioned in the description
• Analyze rural highway safety patterns based on the reported 20 identified blackspot sites
• Support road infrastructure planning based on the 200-meter segment analysis of accident clusters

Strengths

• Approximately 20,000 crash records provide a substantial basis for analysis
• Geographic coordinates assigned using the Australian Map Grid enable spatial analysis
• Focus on 20 specific high-risk sites allows for targeted investigation

Limitations

• Column-level documentation is absent; field semantics must be inferred after download
• Data freshness should be verified; the last metadata update is dated 2026-06-26
• Data may reflect temporal and geographic bias inherent to the source and time period
