1. Journey to Work and Carbon Emissions Kaitie Fernandez Maryville College Budhendra Bhaduri Computational Sciences and Engineering Division August 2009

2. 2Managed by UT-Battelle for the U.S. Department of Energy Overview Background Explanation of Problem Methodology Used Calculated Results Concluding Analysis Acknowledgments

3. 3Managed by UT-Battelle for the U.S. Department of Energy Background Homes Schools Gas stations (regional) Shop Banks (state) Work Cleaners Gas stations (regional) Energy challenges – Regional to national vs. local Useful insight – Characterizing interactions between humans, energy, and transportation networks Success of strategies – Understanding complexity and consequences of proposed systems

4. 4Managed by UT-Battelle for the U.S. Department of Energy Managing and reducing our carbon footprint Modeling and simulation – LandScan USA – Behavior observation over large spatial and temporal scales

5. 5Managed by UT-Battelle for the U.S. Department of Energy Project Objectives Prove or disprove proposed hypothesis – 80% of Americans work in the same county they live in or an adjacent county Determine the number of links and nodes – By county and surrounding counties Observe all if any patterns between workers and links and nodes Relate findings to carbon emissions

6. 6Managed by UT-Battelle for the U.S. Department of Energy Methods ArcMap – Model Builder – Writing scripts LandScan USA – Worker commute model – Links and nodes model Microsoft Access – Managing data – Queries
