ABSTRACT: A Low Ground Clearance Vehicle Detection System (LGCVDS) determines if a commercial motor vehicle can successfully clear a highway-rail grade crossing and notifies the driver when his or her vehicle cannot safely traverse the crossing. That is, differences in elevation between the roadway and track at some locations are such that certain vehicles are more likely to become immobilized with the attendant risk of being struck by an oncoming train.
