Examining the Level of Service Consequence of Transit Signal Priority During Urban Evacuation

Abstract

This research answers the question, during an urban evacuation should regional planners allow transit units signal priority when police assisted traffic controls are not an option. A case study of Washington D.C. shows allowing transit signal priority (TSP) during an urban evacuation has little to no effect on evacuation clearance time. Furthermore, four non-prioritized units are required to accomplish the task of three prioritized vehicles. © 2011 Published by Elsevier Ltd.
