  1. Georgia Tech Seminar – October 29, 2007Implementing Sustainable Transportation at State DOT’sBy Joe Zietsman, Ph.D., P.E.Texas Transportation Institute

  2. Towards a Sustainable Transportation System • Understanding Sustainable Transportation • Quantifying Sustainable Transportation • Applying Sustainable Transportation

  3. Highway 59 On a Good Day

  4. Highway 59 On a Bad Day

  5. Los Angeles, 1956

  6. Los Angeles, Today

  7. Emissions Versus Model Year

  8. Los Angeles, Without Pollution Controls

  9. Interaction of Economy on Ecological System

  10. Air pollution Noise pollution Accidents Global warming Energy use Congestion Social disruption Consumption of land Loss of habitat Hazardous materials Vibration Visual intrusion Waste disposal Water pollution Negative Externalities

  11. Evolution of Sustainable Development • 1700’s - Improvement in standard of living = population surge • 1960’s – Concern over the human impact on the environment • 1970’s – Specific concerns identified: global warming, acid rain, population growth, and loss of tropical forests • 1980 – Sustainable Development used as a term for the first time • 1987 – Brundland Report • 1992 – UN Conference in Rio de Janeiro • 2002 – UN Conference in Johannesburg

  12. Defining Sustainable Transportation Some Appropriate Measure Sustainability Resources Technology Needs Environment Ecology Time

  13. Defining Sustainable Development Sustainable development is development that ensures intergenerational equity by simultaneously addressing the multi-dimensional components of economic development, environmental stewardship, and social equity. It is a dynamic process, which considers the changing needs of society over space and time. Sustainable development can be viewed as a continuum, representing various degrees of sustainability. It must, however, be achieved within resource, environmental, and ecological constraints.

  14. Key Challenges for Sustainable Transportation Sustainable Transportation Understand Apply Quantify

  15. Performance Measures • Simplify • Quantify • Communicate

  16. Categories of Performance Measures I N D E X Input Output Outcome

  17. Acceptable Affordable Measurable Relevant Sensitive Show trends Understandable Benchmark Attributes of a Good Performance Measure

  18. Zoning Speed Mobility Supply Output Efficiency Process Activities Aggregate Bottom-up Integration Mobility Accessibility Demand Outcome Effectiveness Product Results Disaggregate Top-down Old and New Paradigms

  19. TxDOT Goals

  20. Goals of Other Areas - Pretoria, South Africa

  21. Pretoria Corridor Improve mobility and accessibility Safety and security Economic growth Protect the environment Integrate LU and TRP Regulate transit Houston Corridor Improve mobility and accessibility Safety and security Economic growth Protect the environment Integrate LU and TRP Multi-modal system Conserve energy Goals

  22. TCEQ, 5/24/06 Texas Showing Nonattainment Areas

  23. Test Corridor

  24. Goals and Performance Measures Social, economic, environmental

  25. Formulations

  26. Index Formulation 1 1 1 0 0 0 Emissions Energy use Safety Travel cost Travel rate
