Speed Zoning and Traffic Crash Study in New South Wales, 1965 Onward

A study from the NSW Government examines the relationship between speed zoning and traffic crashes on rural highways. The research note, dated 1976, analyzes crash histories to measure the effectiveness of speed zoning as a traffic safety countermeasure. It focuses on roads where a 50 mph prima facie speed limit was replaced with tailored absolute limits.

Use Cases

• Evaluating the effectiveness of speed zoning as a crash countermeasure based on historical crash analysis mentioned in the description
• Studying the relationship between speed variance and crash potential based on concepts described in the research note
• Analyzing traffic safety policy impacts in New South Wales based on the described study of speed-zoned highways

Strengths

• Focuses on a specific policy intervention (speed zoning) with a clear research objective stated in the description
• Produced by a government authority (NSW Government), suggesting an official data source

Limitations

• Data is presented in a PDF format, which may limit machine-readability and direct analysis
• Column-level documentation is absent; field semantics must be inferred after download
• Row count is unknown, which may limit suitability assessment
