Agenda

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

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

4

Clearance Time Definitions

Clearance Time, To Shelter Clearance Time, In-County Clearance Time, Out-of-County Regional Clearance Time

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.

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

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.

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.

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
