Western Australia Road Traffic Counts and Vehicle Averages

Western Australia traffic count sites provide average daily vehicle and heavy vehicle volumes for the latest available year. Main Roads Western Australia collects this data through continuous Network Performance Sites and portable equipment sampling, focusing on the state road network. The dataset includes average weekday volumes for metropolitan areas and average daily volumes for regional areas.

Use Cases

• Model average vehicle and heavy vehicle traffic flows across the Western Australia road network.
• Analyze spatial patterns of traffic volume using site location data for infrastructure planning.
• Compare metropolitan weekday traffic averages with regional daily averages to assess network usage differences.

Strengths

• Data is provided by the authoritative state road authority, Main Roads Western Australia.
• Includes distinct average volume calculations for metropolitan weekdays and regional daily traffic.
• Covers both continuous monitoring sites and wider network sampling for broader coverage.

Limitations

• Specific row count, column details, and sample size are unavailable from the input.
• Data represents averages for a single latest year, limiting longitudinal trend analysis.
• Focus on the State road network may underrepresent traffic on Local Government roads.
