Key findings

Traffic load

  • Darebin ranks 10 of 31 councils by matched SCATS traffic movements.
  • The report covers 122 matched SCATS sites and 18,921.8M cumulative signal movements.

Site-level pressure

  • The highest-volume matched SCATS site is Bell / High in Preston, with 492.4M movements.
  • The top 5 matched SCATS sites account for about 10.5% of the council's ranked SCATS site movements.
  • The top 10 matched SCATS sites account for about 18.4% of the council's ranked SCATS site movements.

Freight evidence

  • The current evidence pack has 2 matched TIRTL detector sites for this council.
  • Those matched TIRTL sites record 0.1M observed trucks, with an overall matched-site truck share of about 1.16%.
  • The highest observed freight detector is Plenty Rd NR Larundel (NB), with 0.1M observed trucks. Its truck share is about 1.17%.
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.

Signal timing / arterial optimisation review

  • Why it appears relevant: Darebin ranks 10 of 31 by matched SCATS traffic movements.
  • Possible DTP / officer question: Can DTP review arterial signal coordination and corridor performance at the highest-volume matched SCATS sites?
  • Evidence basis: SCATS rank 10/31; 18,921.8M movements across 122 matched SCATS sites.

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 155.1M movements per matched SCATS site.

Network coordination review

  • Why it appears relevant: The council has broad SCATS coverage with 122 matched sites.
  • Possible DTP / officer question: Should DTP review signal coordination across the broader council network rather than only the largest individual sites?
  • Evidence basis: 122 matched SCATS sites; rank 10/31.

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.

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.

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

Darebin ranks 10 across Greater Melbourne councils by matched SCATS traffic movements, with 122 matched SCATS sites and 18,921.8M cumulative movements in the current project layer.

The busiest matched SCATS site is Bell / High in/near Preston, with 492.4M movements.
