Abstract:The Federal Railroad Administration (FRA) has engaged in several initiatives to help improve the safety of highway-rail crossings. To that end, FRA recently funded research through the Small Business Innovation Research (SBIR) program to encourage development of a drone-based inspection system for highway-rail grade crossings. Phase 1 of this SBIR project supported VisioStack, Inc. of Greenville, South Carolina, to begin the development of AXIS: Aerial Crossing Inspection System. AXIS uses UAVs (unmanned aerial vehicles, i.e., drones) to perform grade crossing safety inspections with a high level of accuracy and efficiency. AXIS will determine the risk profile of a crossing based on several factors, such as crossing profile (humped condition), sight lines available to automotive traffic, and the location of signage, gates, and other safety appliances. AXIS integrates the major elements of an inspection, from planning to analysis and reporting. Figure 1 displays the AXIS dashboard that provides a convenient user interface to the system.
