The TIRTL Traffic Counts and Classification dataset aggregates speed and vehicle classification into 15 minute time bins. Each rows represents the detected vehicle volume for the given 15 minute period by Austroads vehicle class, speed bin, site, and heading. The Site Key can be joined to the TIRTL Site table for site reference information. DISCLAIMER: The data is considered to be of high accuracy, although it is important to note that mis-classifications can occur, especially during periods of high throughput. Additionally, the devices may experience outages or be decommissioned which results in a unique temporal range for each location.  speed traffic vehicle class volume TIRTL Sites documentDigital Data on the TIRTL site locations.
