Mid-States Highway-Rail Crossing Safety Conference Larry J. Colclasure, P.E. Director of Transportation Operations Texas Department of Transportation Waco District firstname.lastname@example.org
Pedestrian Issues to Consider: How to account for pedestrians. How to handle ped walk time? How to handle ped clearance time?
Vehicular Issues to Consider: How much time is needed to clear the queue? How much time is needed for track clearance green? Is preemption affected by the signal being in different phases? What is preemption delay time?
Railroad Issues to Consider: How much preemption time do I need? How much advance preemption time is needed? How much total preemption time do I have available?
Recent TxDOT Research on Preemption 0-4265 Improved Traffic Signal Operation near Railroad Grade Crossings with Active Devices 0-4746 Non-Vital Advance Rail Preemption of Signalized Intersections near Highway –Rail Grade Crossings 0-5629 Best TxDOT Practices for Signal Timing & Detection Design at Intersection
Recent Tools Developed: LADOT Preemption Form with Gate Interaction (Sean Skehan) Texas Signal Coordination Optimization [Preemption page] (Michael Pratt & James Bonneson)
