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

  1. 1. Evacuation Transportation Modeling and Analysis<br />Florida APA<br />September 8, 2011<br />Bob Hamm, PE<br />Wilbur Smith Associates<br />
  2. 2. Transportation Objectives<br /><ul><li>Satisfy State Requirements</li></ul> Standardized definitions for clearance times<br /><ul><li>Statewide Consistency</li></ul> All RPC regions use same transportation methodology<br /><ul><li>Single or Multi-Region Analysis</li></ul> Each RPC has ability to conduct own analysis<br /><ul><li>Model Interface</li></ul> Allows users ability to easily create and run evacuation scenarios<br />
  3. 3. Model Structure<br /><ul><li>Cube Voyager Platform</li></ul> Consistent with FDOT and all MPOs in Florida<br /><ul><li>Cube Avenue Dynamic Traffic Assignment
  4. 4. Model Structure includes:</li></ul> Behavioral Data – provided by SRESP behavioral studies<br /> Demographic Data – provided by RPCs<br /> Evacuation Network – provided by RPCs<br /> Evacuation Zones – provided by counties based on SLOSH data<br />
  5. 5. Behavioral Data<br /><ul><li>Statewide Behavioral Studies </li></ul> Studies complete in all RPC regions<br /><ul><li>Provides Important Data for Modeling:</li></ul> Who is evacuating?<br /> Where are they going?<br /> When are they leaving?<br />
  6. 6. Small Area Data<br /><ul><li>Regional Demographic Studies </li></ul> RPC regions developing updated demographics<br /><ul><li>Provides Important Data for Modeling:</li></ul> Where/how many people?<br /> Where/how many households?<br /> Where/how many vehicles?<br /> Where/how many mobile homes?<br /> Where/how many hotel/motels?<br /> Where/how many shelters/capacity?<br />
  7. 7. Evacuation Network<br /><ul><li>FDOT Statewide Model Network</li></ul> Used as a starting point – consistent statewide on consistent GIS projection<br /><ul><li>Updated with RPC Evacuation Route input</li></ul> RPCs developing evacuation route data<br /><ul><li>Provides Important Data for Modeling: </li></ul> Roadway locations and number of lanes<br /> Preferred evacuation routes<br /> Traffic control strategies<br />
  8. 8. Evacuation Zones<br /><ul><li>Vulnerability Analysis</li></ul> Evacuation zones will be developed by counties based onresults of SLOSH modeling and easily recognized geographic features (e.g. major roads)<br /><ul><li>Provides Important Data for Modeling: </li></ul> Defines areas that will evacuate (both primary and shadow areas)<br />
  9. 9. Model Process<br /><ul><li>Detailed Methodology is Documented in Volume 8 – Chapter II</li></li></ul><li>Model Process<br />Specify Evacuation Conditions and Initialize Model<br />Split Trips into Destination Purposes<br />Determine<br />Number of Evacuation Trips<br />Distribute Trips Throughout<br />Study Area<br />Determine<br />Time<br />Segment Trips<br />Estimate<br />Background<br />Traffic<br />Post Process Model Outputs<br />Load Trips<br />onto Highway<br />Network<br />
