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.
