  1. Towards Geographies of Consumption Measuring energy consumption fromtransportation in metropolitan areas. Rob Neff Geography and Environmental Systems UMBC neff@umbc.edu Presented at Baltimore Ecosystem StudyUMBC, October 18-19, 2006

  2. Representing the consumptive landscape Transportation and patterns of energy consumption Patterns of division at work and at home Conclusions Future directions Outline

  3. Representing the Consumptive Landscape • All-or-Nothing traffic assignment model • Origin-Destination data from the Census • Emissions from commuters who drove alone • Commuting patterns for all commuters • GHG emissions assigned to residences and workplaces • Hotspots: workplaces with above-average emissions • Results for each hotspot visualized as statistical surfaces • Work-sheds • Car-sheds • Emission-sheds

  4. Study Area

  5. Selected Totals

  6. Selected Efficiency Measures

  7. Center City Commuters Emissions Solo Drivers

  8. Center City Workplace Diversity

  9. Center City Transit & Earnings

  10. King of Prussia Commuters Emissions Solo Drivers

  11. King of Prussia Workplace Diversity

  12. King of Prussia Transit & Earnings

  13. NE Philadelphia Commuters Emissions Solo Drivers

  14. NE Philadelphia Workplace Diversity

  15. NE Philadelphia Transit & Earnings

  16. Emissions Cross Tabulations

  17. Efficiency Cross Tabulations

  18. Conclusions • Urban workplaces were more efficient, per commuter and per driver. • Suburban workplaces were less efficient • ~65% of all commuters • ~76% of all emissions • The pattern of energy consumption is centrifugal • Raw numbers increase away from the city • Efficiency decreases away from the city • Emissions increase away from hotspots • Areas of highest energy consumption also are areas of the greatest racial exclusion • Urban/Suburban dichotomy in both sets of patterns • Northeast Philadelphia as a counter example

  19. Future Directions • Comparative studies • Software development • Extension to air quality issues • Economic, cultural and social drivers of regional consumption patterns • Links to land use • Strengthening links to other scales and places
