Key findings
Traffic load
- Cardinia ranks 30 of 31 councils by matched SCATS traffic movements.
- The report covers 42 matched SCATS sites and 3,501.8M cumulative signal movements.
Site-level pressure
- The highest-volume matched SCATS site is BERWICK-BEACONSFIELD near GOFF in Beaconsfield, with 230.1M movements.
- The top 5 matched SCATS sites account for about 26.3% of the council's ranked SCATS site movements.
- The top 10 matched SCATS sites account for about 48.4% of the council's ranked SCATS site movements.
Freight evidence
- The current evidence pack has 27 matched TIRTL detector sites for this council.
- Those matched TIRTL sites record 9.8M observed trucks, with an overall matched-site truck share of about 5.61%.
- The highest observed freight detector is M1 Inbound - fifth from Cardinia entry (CH 51095), with 0.5M observed trucks. Its truck share is about 4.97%.
TIRTL figures represent matched detector coverage only, not a complete council-wide truck census.
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?
- Do the observed TIRTL freight sites require follow-up with DTP, freight stakeholders or neighbouring councils?
Suggested DTP follow-up themes
How to use this section: these themes translate the report evidence into possible questions for DTP or council officers. They should be treated as prompts for further investigation, not as formal engineering recommendations.
Priority corridor / site cluster review
- Why it appears relevant: The top 10 matched SCATS sites account for about 48.4% of ranked SCATS site movements.
- Possible DTP / officer question: Do the top 10 sites form a corridor or cluster that needs coordinated DTP review rather than isolated intersection treatment?
- Evidence basis: Top 10 SCATS share about 48.4%.
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 BERWICK-BEACONSFIELD near GOFF.
Truck share / local impact review
- Why it appears relevant: Matched TIRTL sites show a relatively high truck share of about 5.61%.
- Possible DTP / officer question: Are truck shares at the highest observed detector sites creating local amenity, safety or access issues?
- Evidence basis: Matched-site truck share about 5.61%.
| Theme | Why | Possible question |
|---|---|---|
| Priority corridor / site cluster review | The top 10 matched SCATS sites account for about 48.4% of ranked SCATS site movements. | Do the top 10 sites form a corridor or cluster that needs coordinated DTP review rather than isolated intersection treatment? |
| State arterial / freeway interface advocacy | The highest-ranked SCATS sites appear to include state arterial, freeway or major corridor interfaces. | Which top-ranked sites are DTP-controlled or state-road interfaces, and what upgrades or operational changes are planned? |
| Truck share / local impact review | Matched TIRTL sites show a relatively high truck share of about 5.61%. | Are truck shares at the highest observed detector sites creating local amenity, safety or access issues? |
Suggested reading order: start with the data-period note, use the map to locate the evidence, read the charts for the pattern, then use the SCATS and TIRTL tables for site-level detail.
Data periods and interpretation
SCATS
Long-period cumulative traffic signal movements from the project’s cleaned SCATS layer, labelled in these reports as 2014–2026.

TIRTL
Observed classified-vehicle detector records from the project’s current TIRTL layer. TIRTL coverage is corridor/detector based, not universal council-wide coverage.

Spatial assignment
SCATS and TIRTL coordinates are assigned to official council/LGA polygons. Suburb labels are geocoded/locality labels and may differ from council boundaries.

TIRTL freight coverage
This council has matched TIRTL detector coverage in the current input layer. TIRTL figures below are observed at matched detector sites, not a complete council-wide freight census.
Corridor caution: Freeway/bridge/tunnel/ramp detector: interpret as corridor coverage, assigned by detector coordinate.

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
Cardinia ranks 30 across Greater Melbourne councils by matched SCATS traffic movements, with 42 matched SCATS sites and 3,501.8M cumulative movements in the current project layer.
The busiest matched SCATS site is BERWICK-BEACONSFIELD near GOFF in/near Beaconsfield, with 230.1M movements.
