  1. NCHRP Report 708 – A Guidebook for Sustainability Performance Measurement for Transportation Agencies - Presentation to the TRB Committee on Transportation and Sustainability (ADD40)

  2. Project Team • Project Lead -Texas Transportation Institute (TTI) • Partners: • Cambridge Systematics • CH2MHill • High Street Consulting • Dr. Steven Muench (University of Washington) • Dr. Henrik Gudmundsson (DTU) • Dr. Ralph Hall (Virginia Tech) • Dr. Greg Marsden (University of Leeds)

  3. Project Goal To develop guidance for state departments of transportation (DOTs) and other transportation agencies to understand and apply concepts of sustainability through performance measurement to enhance their planning, operations, and decision making.

  4. Research Approach Literature review Case studies/interviews Developed a generally applicable framework Developed a user-friendly guidebook and compendium of performance measures Identified future research needs and avenues for dissemination

  5. Research Products Guidebook for practitioners Spreadsheet-based “compendium” of performance measures Final research report

  6. Principles of Sustainability • Sustainability entails meeting human needs for the present and future, while: • preserving and restoring environmental and ecological systems; • fostering community health and vitality; • promoting economic development and prosperity; and • ensuring equity between and among population groups and over generations.

  7. Illustration of the Principles • Equity is overarching – reinforces the environmental, economic and social principles

  8. Approach to Applying Sustainability Definition of sustainability will be contested, but principles of sustainability are non-negotiable Implications of “strong” versus “weak” approach Balance a holistic view with sector-specific considerations Use goals, objectives and performance measures

  9. Performance Measures for Sustainability Performance measures (or indicators) – quantifiable criteria that can be used to evaluate progress toward achieving goals Hierarchy of goals objectives measures can help define robust performance measures. No single indicator/measure is a “sustainability measure” in isolation – a set of measures need to be applied appropriately.

  10. Sustainability Framework

  11. Sustainability Goals • Safety • Basic Accessibility • Equity/Equal Mobility • System Efficiency • Security • Prosperity • Economic Viability • Ecosystems • Waste Generation • Resource Consumption • Emissions and Air Quality

  12. Mapping Goals to Principles • Mapping of the goals to the first three principles: • Using a Yes/No binary score • A rating scale • Comment indicating to what extent the goal addresses the principle. • Mapping of the goals to the equity principle -qualitative judgment of how equity is addressed in the specific context

  13. Template for Mapping Goals

  14. Development of Objectives • Objectives – linked to goals • Specific to particular “focus areas” – • Planning • Programming • Project development • Construction • Operations • Maintenance

  15. Selection and Development of Performance Measures • Linked to objectives • Performance measures • Process measures • Output measures • Outcome measures • Compendium of objectives and measures for 11 goals

  16. Performance Measurement Implementation • Measure refinement • Application level • Focus areas/business units • Whole agency • Application type • Describe • Evaluate • Accountability • Decision Support • Communication

  17. Spreadsheet-Based Compendium • Available on CD with guidebook or on project website • Contains objectives and performance measures organized by the 11 recommended goals • Useful starting point to identify and refine performance measures • Over 400 performance measures listed

  18. Compendium Features • Filter and select measures by: • Goal • Objective • Program relevance • Freight, transit, bike/pedestrian, safety, land use • Principles • Measure type and organizational applicability • Selected measures can be exported into separate sheet.

  19. Conclusions • Key steps are to understand sustainability and apply it in the relevant context • This research provides: • Guidebook with flexible framework • Compendium of measures • Project report
