Multiple track crossings have unique operations that can affect the operation of the traffic signal. Multiple tracks mean there is potential for back-to-back trains and preemption events. Depending on when the subsequent train enters the track circuit, the traffic signal may go from one preemption event and to another with little or no green time for the exit phase before returning to track clearance green. Crossings with multiple tracks should be designed to operate with the track clearance interval as the exit phase to minimize confusion to motorists. If a new preemption event occurs during the exit phase, the traffic signal should restart the track clearance interval and remain in track clearance green until the gate down input is received.
