Abstract:

The American Association of State Highway and Transportation Officials' (AASHTO’s) definition of low-volume roads (LVRs) includes paved roads that receive less than 1 million equivalent single-axle loads (ESALs) during their service period. In the United States, 60% of all roads are LVRs, as both urban and rural communities rely on them. In a recent event, a Category 4 hurricane made landfall in the Houston, Texas, metropolitan area, inflicting serious damage on civil and transportation infrastructures. Low-volume arterial roads were affected by the flooding and by the high volume of trucks that collected the enormous amount of debris left by the massive destruction of homes and their contents. The University of Texas at Arlington (UTA) conducted research to investigate safe and efficient methods for monitoring LVRs with unmanned aerial vehicles that are equipped with a camera for close-range photogrammetry (UAV-CRP). A visible range camera was mounted on an unmanned aerial platform to collect images that were processed into 3D models to provide metric and qualitative information. By analyzing these models, different attributes of the LVRs were obtained, including surficial cracks, deformations, elevation profiles, etc. Information pertaining to the volume and location of debris piled up on areas adjacent to roads was also provided. UAV-CRP technology has proven to be cost-effective and efficient for inspections. It is also an important reconnaissance tool post-natural disasters, when agencies are insufficiently staffed to conduct LVR infrastructure monitoring tasks while also performing rescue and recovery tasks.
