Non-vital advance rail preemption of signalized intersections near highway-rail grade crossings (open access)

Non-vital advance rail preemption of signalized intersections near highway-rail grade crossings

Technical report examining two strategies were investigated to ensure pedestrian clearance time in intersections near highway-rail grade crossings. The first utilizes a lower-level preemption sequence to guarantee full pedestrian clearance to a terminating phase before the traffic signal starts the preemption sequence. The second strategy uses the pedestrian-omit feature to prevent the controller from activating the pedestrian interval if there is not sufficient time in advance of the start of the preemption sequence to provide full pedestrian clearance.
