Overview

Advances in technology now make it possible to collect information about the condition of our roads at speed. The Traffic Speed Deflectometer (TSD) is equipped with doppler lasers, GPS, cameras, temperature probes and 3D sensors; all working together on a heavy vehicle to collect vast amounts of information whilst travelling 80km/h. This information replaces tests that required low speed or stationary vehicles. WARRIP conducted a trial to validate this test collection method and equipment, finding that this method delivered useful information. Cracking, deflection, roughness and rutting data was processed and further data collection projects using the TSD are currently underway.
