10/24/24: TTAP Online Workshop – Preemption of Traffic Signals near Railroad Grade Crossings

August 8, 2024

This workshop will familiarize participants with the basics of the preemption of traffic signals at an intersection adjacent to a railroad grade crossing. The course will include a basic overview of the preemption process, two case studies, a description of the infrastructure requirements, a review of preemption strategies, and the development of preemption timing parameters.

(9:00 a.m. – 3:00 p.m. Eastern Time)

PDHs AVAILABLE

5 Professional Development Hours can be granted for this course. No partial credit available. Attendees must attend at least 90% of the webinar to get 5 PDHs.
