Relocation of Household Dependents For a Daytime No-Notice Evacuation in a Multimodal Transportation System

Sirui Liu, Pamela Murray-Tuite and Lisa Schweitzer

Under no-notice conditions with family members collecting dependents, the locations of these pickup points becomes a crucial factor to efficient evacuation. This paper presents a mathematical program for facilities to relocate, optimally, dependents that need to be picked up. The program, solved using Lingo, is iterated with a traffic simulation model to obtain an optimal set of locations based on anticipated travel times with dependents relocated to those sites. The entire methodology is applied to a case study based on Chicago Heights with three safety thresholds. In two of the three cases, relocation improved evacuation conditions.
