EXECUTIVE SUMMARY

Spotswood Trailers turns Department of Transport and Planning open data into rapid, media-ready intelligence on Melbourne's roads and freight network. This monthly brief combines SCATS traffic signal data and TIRTL classified vehicle data to identify high-volume locations, truck hotspots and emerging changes that may warrant closer review.

Media angle
Fresh DTP open data can now be turned into same-day traffic and freight intelligence, highlighting high-volume signal sites, truck-heavy corridors and emerging movement changes.

Watchlist and responsible-use notes

Watchlist rows are designed for rapid review. They are useful story leads, but should not be treated as automatic proof of causation.

Watchlist only - not a claim of cause

SCATS activation / anomaly candidates

Low or missing baseline sites with meaningful latest-week volumes.

Method

The pipeline downloads the latest DTP open data releases, ingests SCATS and TIRTL records into DuckDB, creates safe reporting views, joins site IDs to friendly names and coordinates, and renders this PDF-ready media brief. Supporting CSVs, named site tables, map images and methodology notes can be supplied with the media pack.

Publication checklist

  • Check the top named locations manually.
  • Check any unusual road-name text before publication.
  • Treat anomaly rows as leads, not conclusions.
  • Frame the story as open-data intelligence.
