Low Ground Clearance Vehicle Detection and Warning
The Federal Railroad Administration’s (FRA) Office of Research, Development and Technology (RD&T) sponsored a Small Business Innovation Research (SBIR) Phase II project from July 31, 2014, to July 29, 2016. This took place at the Advanced Technology and Research Corporation (ATR) facility in Beltsville, MD, to advance the Low Ground Clearance Vehicle Detection System (LGCVDS) concept for highway-rail grade crossings to provide a qualitative and quantitative assessment of the system under a set of representative conditions. A significant portion of the effort was devoted to assembling a viable sensor system. As the crossing profile is a critical component for the hang-up assessment, ATR developed a workflow to ingest crossing data collected by ENSCO, Inc., in order to derive a crossing profile representation that is suitable for the LGCVDS.
