Light rail and Heavy rail Grade crossings are regulated by the Federal Transit Administration. The Federal Transit Administration defines two types of Grade crossings: (1) At grade, mixed, and cross traffic crossings, meaning railway right-of-way over which other traffic moving in the same direction or other cross directions may pass. This includes city street right-of-way; (2) At grade with cross traffic crossings, meaning railway right-of-way over which no other traffic may pass, except to cross at grade-level crossings. This can include median strip rights-of-way with grade level crossings at intersecting streets.
Commuter rail Grade crossings are regulated by the Federal Railroad Administration. The Federal Railroad Administration defines a Grade crossing as a location where a public highway, road, street, or private roadway, including associated sidewalks and pathways, crosses one or more railroad tracks at grade.
The drop in the number of Injuries beginning from 2002 is due largely to a change in definitions by the Federal Transit Administration. The Injury threshold for filing an incident report changed to be two or more Injuries requiring immediate medical transportation away from the scene, or one or more Injuries requiring immediate medical transportation away from the scene in the case of incidents at grade crossings or along rail right-of-ways in 2002. Previously, any Injury was reportable. Further, there were National Transportation Database definition changes made in 2008 to simplify the Injury thresholds for filing an incident report. FTA simplified this threshold to being simply one or more Injuries requiring immediate medical transportation away from the scene. This simplification resulted in larger reported number in Injuries since 2008.
