SCATS Sample Data

​Sydney Coordinated Adaptive Traffic System (SCATS) collects traffic volume data using detectors at traffic signals (located near stop lines).  SCATS data is captured 24 hours a day (midnight to midnight). Data is available at all signalised intersections (including pelican/puffin crossings) across the state. This data can be used to measure traffic volume including lane and/or turning counts (where available).

 

Request SCATS Data using the online request form. 
 
 
Please allow between 3-5 business working days to receive SCATS volume data.
 

When requesting SCATS DATA consider the following

  • When identifying intersections include the names of at least two (2) intersecting roads
  • Information for pelican/puffin crossings will require the road name of the crossing, and intersecting road names before and after the crossing
  • Latest full week is for seven (7) days, Monday to Sunday. Public and school holidays are excluded from counts
  • The custom date range option is inclusive of all dates within the range and needs to be greater than a 24 hour period
  • Historical counts older than two (2) years are not available
  • Road works will affect traffic volumes and faulty detectors will not detect vehicles
  • Data may not be available on slip lanes where there are no detectors or signals
  • Data recorded is for traffic volume only and does not include vehicle types moving through the intersections, such as trucks, bus or motorcycles

 

SCATS Data Output Samples

Column (Standard and Separate Row)
 
Column - Standard
 
Traffic Management companies will find this output suitable for their needs.  Traffic volume data outputs can be provided in intervals of 5, 15, 30 or 60 minutes; the 60 minute (hourly) output being the most applicable for traffic volumes.
 
Sample 1: Column - Standard below shows a two (2) day count of Traffic volume data for 11 detectors side by side with totals by 60 minute time intervals and totals for each row over a 24 hour period.  This output is provided in text file format.

Sample 2: Column - Separate Row below shows one (1) day count for two (2) detectors (named as approaches) by 60 minute (hourly) time intervals.  Here the detectors are listed separately below each other and includes the traffic volume totals for each detector and a sub total column for each detector. This output is provided in text file format.

Table (Standard and Separate Row)

Table - Standard

Traffic consultancies may find this output suitable for their use.  Traffic volume data outputs can be provided in intervals of 5, 15, 30 or 60 minutes. 

 
Sample 3: Table - Standard below shows a two (2) day count for seven (7) detectors by 60 minute (hourly) time interval.  The traffic volumes are a combined total of all seven (7) detectors.  The table is separated into two (2) halves showing 12 hour time interval.  The output is provided in text file format.

Sample 4: Table - Separate Row below shows a one (1) day count for four (4) detectors by 60 minute (hourly) time interval. The traffic volumes are listed in a separate table (row) for each detector.  The table format is separated into two (2) halves each half showing 12 hours by time interval for each detector.

SCATS Sample Graph Format

Graph (Standard and Separate Row)
 
Graph - Standard
 
Traffic consultancies may find this output suitable for their use.  Outputs can be provided in intervals of 5, 15, 30 or 60 minutes.
 
Sample 5: Graph - Standard displays all available detectors as a combined volume total over 24 hour day by 60 minute (hourly) time interval as a line graph.  Customers should also request SCATS maps to ensure that all approaching lanes do contain a detector.  Many left turn slip lanes do not contain detectors and volumes may be missing from the intersection.  The output is provided in image file format.

Graph - Separate Row
 
Traffic consultancies may find this output suitable for their use. Traffic volume data outputs can be provided in intervals of 5, 15, 30 or 60 minutes.
 
Sample 6: Graph - Separate Row below shows three (3) detectors as a separate line volume total over 24 hour day by 60 minute (hourly) time interval as a line graph.  Customers should also request SCATS maps to ensure that all approaching lanes do contain detectors.  Many left turn slip lanes do not contain detectors and volumes may be missing from the intersection.  The output format is provided in image file format.

SCATS Map Sample

The sample SCATS Map below shows the intersection of Stirling Hwy/Broadway/Hampden Rd (Intersection TCS 66).  The following points will assist users in understanding a SCATS Map:

  • 13 detectors are shown near stop or give way lines
  • The numbers allocated to each detector on the SCATS map correlates with the SCATS Column, Table and Graph output data 
  • The map shows 8 traffic light phases
  • The sample includes a detailed layout view of all through-lanes and slip-lanes (where applicable)

Sample Light Maintenance Drawings

 
Light Maintenance (LM) Drawings are generally used so show “As Constructed” Traffic Signal Plans (drawing type A) and Line and Sign markings (drawing type B) at any traffic signal controlled intersection.  LM drawings are typically provided in PDF.

Drawings/Plans/Charts

 
Things to consider:
  • LM Drawings are useful when an intersection has been modified and can be used to reference data prior to the change
  • LM Drawings may not be available if the plans have not been handed over by a Main Roads contractor on completion of the project
  • LM Drawings are provided in PDF or ACAD format

 

Other SCATS Information

 
Customers seeking to analyse traffic behaviour can request Link and Split Plan Information (to check if traffic signals are interconnected), Strategic Monitor Chart (see sample below) or a number of SCATS System Files, which are provided by our Traffic Operations Centre.
