With the exception of the evacuation network, the package operates entirely on data available from official sources and uses models that have been estimated from observed evacuation behavior in past hurricanes. In the package, population is synthesized from census data, storm data is downloaded from the National Hurricane Center, and evacuation behavior is predicted in terms of the number of households evacuating in each 6-hour period, their destination, mode of travel, type of refuge, route, and the resulting traffic flow on the network. A user specifies a past or current storm to be analyzed, the area to be evacuated, if and when evacuation orders and/or contraflow are to be implemented, and the package estimates the consequences of the scenario in terms of average travel time, delay, speed, and degree of migration in each time period.125
