Traffic Digest: traffic volume at count sites - Western Australia

The location of traffic count sites across selected roads on the road network. This layer provides the average number of vehicles and heavy vehicles for the latest year of traffic data available. The traffic volumes in this layer are expressed as the average number of vehicles at each location on a typical weekday (Monday to Friday) for the metropolitan area, and a typical day (Monday to Sunday) for regions outside the metropolitan area.

Main Roads undertakes traffic counting throughout Western Australia. Strategic locations are monitored on a continuous basis and are referred to as Network Performance Sites (NPS). Sampling of the wider network is performed using portable equipment over a short period. Although many Local Government roads are counted the focus is on providing information about the State road network. The Integrated Road Information System (IRIS) Reporting Centre provides a number of reports that provide traffic volume and vehicle classification reports.
