1. August 20, 2015 Transportation Analysis Meeting 2015 Update Tampa Bay Region Roberto O. Miquel, AICP

2. Agenda  Introductions  SRESP Transportation Element Objectives  Clearance Time Definitions  Changes to Study  Analysis Results  Questions/Comments 2

3. Transportation Objectives  Satisfy State Requirements  Standardized definitions for clearance times  Statewide Consistency  All RPC regions use same transportation methodology  Single or Multi-Region Analysis  Each RPC has ability to conduct own analysis  Graphic User Interface  Allows users ability to easily create and run evacuation scenarios 3

4. Clearance Time Definitions  Clearance Time, To Shelter  Clearance Time, In-County  Clearance Time, Out-of-County  Regional Clearance Time 4

5. 1. Clearance Time, To Shelter  The time necessary to safely evacuate vulnerable residents and visitors to a “point of safety” within the county based on a specific hazard, behavioral assumptions and evacuation scenario. Calculated from the point in time when the evacuation order is given to the point in time when the last vehicle reaches a point of safety within the county.  All in-county trips reach their destination w/in county.  Does not include any out-of-county trips. 5

6. 2. Clearance Time, In-County  The time required from the point an evacuation order is given until the last evacuee can either leave the evacuation zone or arrive at safe shelter within the County. This does not include those evacuees leaving the County, on their own.  All in-county trips reach their destination w/in county  All out-of-county trips exit the evacuation zone, but may still be located in the county  Does not include out-of-county pass-through trips from adjacent counties, unless they evacuate through an evacuation zone 6

7. 3. Clearance Time, Out of County  The time necessary to safely evacuate vulnerable residents and visitors to a “point of safety” within the county based on a specific hazard, behavioral assumptions and evacuation scenario. Calculated from the point an evacuation order is given to the point in time when the last vehicle assigned an external destination exits the county.  Roadway network within county is clear.  All out-of-county trips exit the county, including out-of-county pass- through trips from adjacent counties.  All in-county trips reach their destination. 7

8. 4. Regional Clearance Time  The time necessary to safely evacuate vulnerable residents and visitors to a “point of safety” within the (RPC) region based on a specific hazard, behavioral assumptions and evacuation scenario. Calculated from the point in time when the evacuation order is given to the point in time when the last vehicle assigned an external destination exits the region.  Roadway network within RPC is clear.  All out-of-county trips exit the RPC, including out-of-county pass- through trips from adjacent counties.  All in-county trips reach their destination. 8

9. Changes to Study  Small Area Data based on 2010 Census  Scenario years are now 2015 and 2020  Traffic Routing Algorithm has been modified to improve the stability of model results  Some regions have updated evacuation zones  Transportation projects have been updated to reflect 2015 and planned 2020 conditions  Shelter locations and capacities have been updated where necessary 9
