Railroad Bridge Inspections for Maintenance and Replacement Prioritization Using Unmanned Aerial (UAVs) with Laser Scanning Capabilities

This research includes a concept test of integrating unmanned aerial vehicles (UAVs) and 3D laser technologies to assess the structural condition of simply supported spans conforming steel railroad bridges, thereby informing subsequent prioritization of the need for more detailed inspections. The end result will include a feasibility and cost analysis of using and developing UAVs and 3D laser technologies for railroad bridge inspections and assessment at the network level (i.e., for multiple spans and multiple bridges within a given territory). The main emphasis of this research is freight traffic and transportation, but the application is expected to assist any other type of railroad operations such as passenger and intercity passenger rail.
