  7. Performance Measure Challenges • Some measures only applicable to certain scales • How do we establish outputs vs outcomes? • Many measures come from models and not real world observations (many assumptions) • Conflicting or contradictory goals • Correlation does not mean causation • Redundancy in measures based on common initial variable

  8. Needs Assessment Performance Measures Travel Demand Model Output Composite Analysis Measures

  9. Regional Travel Demand

  10. 2010 Travel Sheds from CBD by Time of Day

  11. Scenario Quadrilaterals

  12. Potential Walking Demand Measure • 10 minute walking sheds • “Potential demand” for short walking trips • Proximity to retail/service • Street Network • Number of households • Desired to match demand with infrastructure improvement

  13. Potential Walking Demand Measure Retail & Service Employment * Households * Intersections Retail & Service Employment + Households + Intersections

  14. Potential Walking Demand Measure

  15. Potential Walking Demand Measure Cumberland Perimeter Center Lindbergh Buckhead Midtown Decatur Downtown VAHighlands

  16. Potential Walking Demand Measure

  17. Potential Walking Demand Measure Transit Stations LCI Areas

  18. Multimodal Accessibility Measure • Looked at travel times to employment by different modes using the travel demand model • 30 minutes by car • 15 minutes by foot • 45 minutes by transit • Areas with the ability to reach employment by multiple modes score better

  19. Multimodal Accessibility Measure 2010

  20. Multimodal Accessibility Measure

  21. Multimodal Accessibility Measure Envision 6 2040

  22. Multimodal Accessibility Measure Concept 3 2040

  23. Congestion Ranking – Intensity • Measures peak daily expected congestion • Maximum value from AM/PM weighted TTI

  24. Congestion Ranking – Duration • Measures how much time of the day a facility is congested • Weighted V/C ratio by time and distance

  25. Congestion Ranking – Extent • Measures the number of people impacted • Total facility vehicle hours of delay

  26. Congestion Ranking – Most Congested

  27. Needs Assessment Conclusions • Intercounty travel demand is expected to increase • Rail travel offers good reliability • Sprawling development hinders mode choice • Measures serve as a tool for future project evaluation • Increasing walkability and mode options helps: • Reduce emissions • Improve public health • Improve transportation equity
