A traffic control preemption system monitors an operating state of a railroad crossing, without requiring an interface with railroad crossing equipment, and communicates information to a traffic controller of an adjacent signalized roadway intersection to improve vehicular traffic flow at the railroad crossing. The traffic control preemption system is configured to make real time health assessments of preemption system functionality and provide a degree of redundancy and failsafe operation to the traffic control system.
