Title:

Model of Household Trip Chain Sequencing in an Emergency Evacuation

Abstract:

This paper presents an evacuation modeling framework that bridges the gap between observed household behavior and traditional evacuation models. The gap between observed behavior and theoretical models leads to longer-than-expected evacuation times. Through a series of two linear integer programs, this paper provides an expression for the household behavior in evacuation conditions. The first formulation determines the meeting location for the household members. The second formulation determines which drivers pick up each of the family members and the sequence of the collection. Tying these linear programs to traffic simulation software allows for a more complete evacuation simulation. Furthermore, information supply strategies may be incorporated into the simulation.
