Abstract:The Federal Highway Administration's Federal Lands Highway Innovation and Research Council Research Program funded this research to identify opportunities and challenges related to using uncrewed aircraft systems (UAS) to support condition inspections for Federal Land Management Agency Roads. The report synthesizes the current state of the practice, identifies ways that UAS-acquired data can be integrated with existing road condition rating approaches, and describes the outcomes of a demonstration to fly UAS equipped with various sensors at a National Wildlife Refuge to collect information necessary to automate road distress detection. Results from the demonstration are compared to results from an inspection of the same roads using customary approaches.
