Traffic Monitoring

We undertake traffic counting throughout Western Australia. Our focus is on providing information about the State Road Network and significant Local Government roads.

Traffic data is obtained by installing equipment on the road. We install at night when traffic volumes are lower to ensure the safety of road users and workers. Our traffic counters are identified with the Main Roads logo and contact number. The counts are on the road for approximately four days.

If a counter is creating a hazard to road users or is causing distress to residents due to noise, please contact 138 138 for advice.

Perth Metropolitan Traffic Counts 

Each year traffic counting is undertaken at approximately 1500 locations in the Perth Metropolitan Area to obtain a sample of information about the road network.

Traffic counts provide information about the number of vehicles travelling at locations. Some locations have information about the type of vehicle (based on Austroads 1994 Vehicle Classification ) and speed of travel.

Continuous Traffic Monitoring Locations

Traffic is monitored continuously at around 150 locations statewide. These sites provide information about strategic locations 24hrs a day, 7 days a week.

There are three types of information gathered as continuous traffic data:

  •  Bicycle monitoring captures travel on cycle paths predominantly in the Perth Metropolitan Area
  • Vehicle Mass is provided at some locations in addition to classification information
  •  Classification sites record the number and type of vehicles (based on Austroads 1994 Classification Scheme). Speed information can also be obtained from these counts

Statewide Traffic Digest

This report summarises the average number of vehicles travelling at locations within Western Australia. Traffic volumes and freight (given as a percentage) are provided for the latest available six years.

Ramp and Rotary Diagrams

Whilst we aim to describe traffic count locations using road names as they would appear on a map or street sign, some locations counted near on/off ramps or rotaries (roundabouts) may be identified using Main Roads internal road numbering system i.e. H704. The Ramp and Rotary Diagrams show these relative to the adjoining roads and include the road numbers for reference;
