Title: Does Non-Compliance with Route/Destination Assignment Compromise Evacuation Efficiency?

Abstract

This paper documents studies of two real-world network evacuation cases, each with a different, but proven, simulation software package. The purpose of these studies was to examine whether the rate of evacuees' compliance with predetermined route/destination assignments would have an impact on the efficiency of evacuation operations. Results from both cases suggest that a rate of less than 100% compliance does not compromise evacuation efficiency. In fact, although this is counter-intuitive, evacuation efficiency would actually improve as a result of "sensible" non-compliance on the part of the evacuees. A closer observation of the results revealed that the somewhat unexpected improvement results from a reduction in congestion along designated evacuation routes as evacuees spread out to less prominent parallel streets and other non-congested outbound routes. This suggests that by being limited by the zone-to-zone and one-to-one assignment framework, conventional evacuation plans may have fallen short of providing the most efficient guidance to evacuees. To address this issue, some systematic means, perhaps simulation-based, should be performed to assess the zone partitions, route designations, and destination assignments in existing evacuation plans. Thus, evacuation planning with route/destination assignments based on origin zones may be flawed and may deserve reconsideration.
