  1. Selecting and Applying Indicators for Transport Project Appraisal Dr Greg Marsden G.R.Marsden@its.leeds.ac.uk

  2. Outline • Project Appraisal • Limitations with current approach • New indicators • Next steps

  3. Project Appraisal • “Appraisal is the process of checking that value for money is achieved in delivering Government aims” (UK DfT) • “to help design and select projects that contribute to the welfare of a country” (World Bank) • “to develop sound and objective information necessary for informed decision making” (FTA)

  4. Project Appraisal • Transport appraisal • UK - Required for all schemes > $9.6M Current Situation Do Nothing Option A Option B -50 -40 -30

  5. Project Appraisal • Environment • 10 sub-objectives (local air quality, noise, greenhouse gases, biodiversity, heritage…) • Economy • 5 sub-objectives (VfM, consumer and producer benefits…) • Safety • 2 sub-objectives (accidents, security) • Accessibility • 3 sub-objectives (options, severance, physical) • Integration • 3 sub-objectives (interchange, land-use, other policies)

  6. Strategic Environmental Assessment • Since July 2004 (parallel to EIS) • Applies to plans and programmes • Only requires environmental assessment • Process • Baseline, problems, indicators, alternatives… • Report on • positive / negative • scale • magnitude • time scale • frequency • duration, • direct/indirect • cumulative

  7. Limitations • Appraisal hides absolute impacts • Limit guidelines ignored • Cumulative effects ignored • Long-term impacts ‘discounted’ • Many aspects of sustainability ignored • 12 indicators reported • 3 indicators strongly related • 24 indicators not considered

  8. Limitations

  9. Limitations X X X X X X

  10. Selection • Good measures of sustainable outcomes • Total CO2, CO2/capita, CO2/trip • Capable of measurement • estimation/forecast • Sensitive to spatial change • e.g. air quality levels vs. toxic emissions • Capture distributional impacts • Understandable/rational

  11. Application • Importance of a core common approach • National guidance • Outcome indicators are vital • Avoid specifying solutions • Allows for more consistent benchmarking • Supported by meaningful process (output) indicators • Absolute and relative changes • Importance of changes
