Book excerpt: The Institute of Transportation Engineers (ITE) prepared this report to reflect the current state-of-the-practice and to provide the user with a broad overview of key considerations for the preemption of traffic signals near railroad grade crossings. Where a signalized intersection exists in close proximity to a railroad crossing and either queues from the intersection impact the crossing or queues from the crossing impact the intersection, the railroad signal control equipment and the highway traffic signal control equipment should be interconnected. The normal operation of the traffic signals controlling the intersection should be preempted to operate in a special control mode when trains are approaching. This proposed recommended practice was written primarily for an audience of engineers working for public agencies, railroads, and public transit agencies engaged in signal design and operational timing. The objective of this proposed revision is to include new information on the design and operation of traffic signal preemption that has been learned since the previous edition was published.
