Aggregate-level demand management in evacuation planning
Without successful large-scale regional evacuations, threats such as hurricanes and wild-fires can cause a large loss of life. In this context, automobiles are oftentimes an essential transportation mode for evacuations, but the ensuing traffic typically overwhelms the roadway capacity and causes congestion on a massive scale. Congestion leads to many problems including longer, costlier, and mo...
متن کاملA Novel Approach to Evacuation Route Planning
Shashi Shekhar Qingsong Lu, and Sangho Kim AHPCRC-UM The goal of evacuation route planning is to identify routes that canbe used to minimize the time required to move vulnerable populations to safe destinations. Evacuation route planning is a key component of effective disaster emergency management and homeland defense preparation. As such, it is an important challenge facing the U.S. Army, whi...

متن کاملA capacitated network flow optimization approach for short notice evacuation planning
We present a capacity constrained network flow optimization approach for finding evacuation paths, flows and schedules so as to maximize the total evacuees for short notice evacuation planning (SNEP). Due to dynamic nature of this optimization problem, we first construct a time-expanded network that expands the static network over the planning horizon for every time interval. Since the resultin...
متن کاملChallenges in Evacuation Route Planning for Incident Management
The recent loss of lives and traffic jams (Figure 1) for tens of miles as hurricanes Rita and Katrina approached the Gulf coast demonstrate the enormous difficulty in evacuating urban areas [6]. Besides hurricanes, evacuation may be necessary due to other potential disasters, e.g., fire, terrorism, and nuclear or chemical plant accidents. Thus, the local emergency management community engages i...
