Historic Traffic Link Statistics with Congestion and Delay Metrics

Traffic Links Stats is a dataset containing historic traffic link definitions and performance statistics, including geometry, from the Australian Capital Territory government. The data is archived from a real-time API, with historical samples captured every 5 minutes. The dataset was last updated by www.data.act.gov.au in December 2023.

Use Cases

• Predicting link-level Congestion or Delay using features like Speed, IsFreeway, and Length.
• Analyzing traffic Trend and Score over time using the IntervalStart timestamp.
• Modeling travel time (TT, MinTT) based on road characteristics such as MinNumberOfLanes and Direction.
• Identifying recurring bottlenecks by correlating ExcessDelay with specific OriginSiteId and DestSiteId pairs.

Strengths

• Includes 20 distinct features covering traffic performance, geometry, and network topology.
• Data is sampled from a real-time source updated every 30 seconds, providing a high-frequency base.

Limitations

• The historical archive samples only every 5 minutes, potentially missing short-term fluctuations.
• Sample size and temporal coverage are unknown, limiting assessment of statistical representativeness.
