DESIGN GUIDELINES FOR RAILROAD PREEMPTION AT SIGNALIZED INTERSECTIONS

This paper presents guidelines for determining when a preemption capability is required at isolated intersections, and for calculating the duration of the preemption timing intervals. The guidelines is based on a queuing analysis rather than a single, apparently subjective, numerical value. The guidelines should be useful in identifying and correcting deficiencies at existing locations having railroad preemption phasing. Language: en
