9/8 thur 10:45 | statewide regional evacuation study program 1
DESCRIPTION
Earl J. Baker With an updated Evacuation Study for each of the 11 regions, Florida has one of the only statewide evacuation studies in the Nation. This session will educate participants on its fundamentals, including HOW and WHY it was created and its implementation across a variety of planning disciplines. Explanations of the major components of the Evacuation Study, including its complex evacuation transportation models, statewide coordination, behavioral surveys, and associated behavioral assumptions and advanced GIS modeling tools. Planners will gain a better understanding of the purpose, data and methodology of the Studies and how to implement its findings in their planning documents.TRANSCRIPT

Behavioral Assumptions for Planning
Coastal Counties 6 zones 5 storm categories 2 house types 7 behaviors*
▪ Evacuation participation rate▪ Type of refuge (4)▪ In vs. out of county destinations▪ Vehicle use
Maximum Probable Evacuation Participation Rates Storm Threat Scenario
Site-built Homes Cat 1 Cat 2 Cat 3 Cat 4 Cat 5
Cat 1 Surge Evacuation Zone 55 65 75 85 95

Evacuation rate indicates the percent of residents who will leave their homes to go someplace safer from each zone in each storm threat scenario. Figures are based on the assumption that officialsorder evacuation for surge evacuation zones corresponding to storm category, plus all mobile homes and manufactured homes. Figures also assume that the actual storm track passes very close to the area being evacuated.
