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 Managed by UT-Battellefor 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 Managed by UT-Battellefor 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 Managed by UT-Battellefor 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
