Stonnington Traffic & Freight Intelligence Report
Independent council-area traffic and freight report generated from SCATS and TIRTL project outputs. Generated: 2026-06-22 16:34
Key findings
Traffic load
- Stonnington ranks 15 of 31 councils by matched SCATS traffic movements.
- The report covers 119 matched SCATS sites and 17,510.8M cumulative signal movements.
Site-level pressure
- The highest-volume matched SCATS site is Princes Highway East near THE AVENUE in Windsor, with 470.3M movements.
- The top 5 matched SCATS sites account for about 12.0% of the council's ranked SCATS site movements.
- The top 10 matched SCATS sites account for about 21.8% of the council's ranked SCATS site movements.
Freight evidence
- No matched TIRTL detector sites are available for this council in the current input layer.
- This should be treated as a freight detector coverage gap, not evidence of no truck activity.
How to read this
- SCATS evidence shows long-period traffic signal movements at matched signal sites.
- TIRTL evidence shows observed detector coverage where matched detectors exist.
- Use the map first to locate the evidence, then use charts and tables for detail.
Useful questions for council / DTP
- Which of the highest-volume SCATS sites align with current local traffic, safety or corridor priorities?
- Do the mapped high-pressure sites match the locations residents and councillors complain about most often?
- Should the highest-ranked sites be reviewed for signal timing, pedestrian safety, freight impacts or state-road advocacy?
- Would better TIRTL or freight detector coverage help the council understand truck activity more clearly?
Suggested DTP follow-up themes
Freight detector coverage request
- Why it appears relevant: No matched TIRTL detector sites are available for this council in the current input layer.
- Possible DTP / officer question: Can DTP provide better truck/freight evidence or detector coverage for this LGA?
- Evidence basis: TIRTL coverage gap in current matched detector layer.
State arterial / freeway interface advocacy
- Why it appears relevant: The highest-ranked SCATS sites appear to include state arterial, freeway or major corridor interfaces.
- Possible DTP / officer question: Which top-ranked sites are DTP-controlled or state-road interfaces, and what upgrades or operational changes are planned?
- Evidence basis: Top SCATS evidence includes Princes Highway East near THE AVENUE.
High-intensity site review
- Why it appears relevant: Average movement per matched SCATS site is high compared with other councils.
- Possible DTP / officer question: Are a smaller number of very heavily loaded sites carrying disproportionate traffic pressure?
- Evidence basis: Average 147.1M movements per matched SCATS site.

Data periods and interpretation
Long-period cumulative traffic signal movements from the project’s cleaned SCATS layer, labelled in these reports as 2014–2026.
Observed classified-vehicle detector records from the project’s current TIRTL layer. TIRTL coverage is corridor/detector based, not universal council-wide coverage.
SCATS and TIRTL coordinates are assigned to official council/LGA polygons. Suburb labels are geocoded/locality labels and may differ from council boundaries.
Sensor map
Bright blue circles show matched SCATS traffic signal sites. Bright orange-red circles show matched TIRTL detector sites where TIRTL coverage exists. The black outline shows the official council/LGA boundary. Sites are assigned to council areas by coordinate inside the official LGA polygon.
No matched TIRTL detector coordinates are available for this council in the current input layer. The map still shows matched SCATS sites.

Method and interpretation notes
SCATS site coordinates and TIRTL detector coordinates are assigned to official council/LGA polygons using point-in-polygon spatial joins. SCATS figures are long-period cumulative traffic signal movements from the project’s cleaned SCATS layer. TIRTL figures are observed classified-vehicle counts from matched detector sites and should be interpreted as corridor/detector evidence rather than a full council-wide truck census.
The “Geocoded suburb/locality” column comes from the site lookup/geocoding layer. It is useful for orientation, but the council assignment is controlled by the site coordinate falling within the official council/LGA polygon.
Executive summary
Stonnington ranks 15 across Greater Melbourne councils by matched SCATS traffic movements, with 119 matched SCATS sites and 17,510.8M cumulative movements in the current project layer.
The busiest matched SCATS site is Princes Highway East near THE AVENUE in/near Windsor, with 470.3M movements.
