Abstract
Preemption of traffic signal controllers near railroad grade crossings equipped with active warning devices is often required because queues from the intersection can extend back over the tracks, thereby creating the potential for a serious vehicle-train accident. The purpose of this article is to present guidelines for determining when a preemption capability is required at isolated intersections and for calculating the duration of the preemption timing intervals.
