Automated Road Condition Survey Using Laser Imaging and Ranging Detection - June 2022

Infrastructure Committee conducted an Automated Road Condition Survey using Laser Imaging and Ranging Detection in June 2022. The survey covered 5835 km of roads with a value of $7B. It included sub-arterial, arterial roads, and industrial access, with key indicators for performance criteria. The survey also assessed flood-affected roads post a significant event in February 2022, utilizing modern survey practices. Various technologies like Laser Deflection Truck and Laser Van were employed for assessing road conditions. The practices included GPS positioning, pavement distress analysis, roughness evaluation, and crack detection systems. Source: Australian Road Research Board.
