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 and truck hotspots, while quality gates prevent incomplete observation windows from being presented as confirmed traffic growth.

Media angle
Fresh DTP open data can be turned into same-day traffic and freight intelligence while complete-window checks separate reliable volume findings from provisional or suppressed change candidates.

SCATS: busiest locations and provisional movement changes

SCATS data is summarised by named traffic signal sites. Tables below use the current update window and show top locations by total movement and provisional first-window versus latest-window comparisons. These change rows remain provisional until a separate SCATS completeness gate is applied. Site IDs and location names are clickable map links where coordinates are available.

Quality review, method and caveats

Quality-controlled change reporting

Change claims require complete and comparable observation windows. Rows that fail those requirements are retained as QA evidence and excluded from the public uplift ranking.

TIRTL quality gate passed - incomplete comparisons are not presented as traffic growth

SCATS activation / anomaly candidates - provisional

Low or missing baseline sites with meaningful latest-window volumes. These are data or site-review leads, not confirmed traffic growth.

TIRTL comparison rules

Latest complete Monday-Sunday week versus the median of up to four preceding complete Monday-Sunday weeks. A valid day requires at least 92 of 96 intervals. Publication requires at least 2 complete baseline weeks, at least 500 latest trucks per day, at least 20.0% truck growth and at least 2.0 percentage points of truck-share growth.

Responsible use

  • TIRTL figures are classified passings, not unique vehicles or journeys.
  • The same vehicle may be counted at multiple monitoring locations.
  • Volume and truck-share rankings do not establish cause.
  • SCATS first/latest change rows remain provisional pending their own completeness gate.
  • Check names, coordinates and unusual road text before publication.
