TRB's National Cooperative Highway Research Program (NCHRP) Synthesis 507: Traffic Signal Preemption at Intersections Near Highway–Rail Grade Crossings documents the current practices of traffic signal preemption deployed at intersections adjacent to railway grade crossing in both the United States and Canada. The study provides information on practices dealing with traffic signal preemption, maintenance, funding, and operations.
