Integrated Evacuation Network Optimization and Emergency Vehicle Assignment

Abstract

Three treatments are combined in the design of evacuation network operating plans: reversing lanes, eliminating intersection crossings, and reserving lanes for use by emergency vehicles. An optimization approach is taken and casts the problem as a form of discrete network design, with constraints imposed by emergency vehicle lane assignment. What have previously been separate strands of work examining ways of configuring road networks for effective evacuation performance are integrated. A case study for a network around a nuclear power plant illustrates the usefulness of this integrated approach.
