Analysing and Mitigating Queues at Signalized Intersections Adjacent to Railway Crossings (Poster)

Traffic signal control and railway crossing active warning systems provide the highest degree of control available at intersections and railway crossings, short of grade separation. Two issues may occur due to the close proximity of traffic signals and a railway crossing with an active warning system: Influence Zone (signal to tracks) queue; Gate Spill Back (tracks to signal) queue. Where a signalized intersection exists in close proximity to a railway crossing, signal pre-emption may be used, which requires coordination between traffic signals and the railway warning system. Signal pre-emption serves to ensure that the actions of these separate traffic control devices complement rather than conflict with each other. The Region of York identified six signalized intersections that appeared to be regularly extending from the traffic signals past a nearby set of railway tracks. According to the Transport Canada RTD-10 guidelines, signal pre-emption should be considered. The Region wished to examine the underlying causal factors that were contributing to the queues at these locations, in order to determine alternative solutions (other than signal pre-emption). The purpose of this project is to present a methodology for analyzing and characterizing queues at signalized intersections in addition to identifying techniques for evaluating the effectiveness of potential mitigating solutions.
