  1. Beyond Business as Usual: Ensuring the Network We Want is the Network We Get RESULTS David Levinson, Norah Montes de Oca and Feng Xie Mn/DOT Final TAP Meeting May 30th, 2006

  2. Project Outline • Interviews • Develop flowcharts • Develop IF…THEN RULES • Develop models • Update simulation program data • Incorporate all models • Compare different scenarios • Analyze results • Make conclusions and suggestions

  3. General Framework

  4. Investment Model

  5. Models used: Correlation results:

  6. Models used: (continuation)

  7. Calibration RMSE= 33% Average peak hour difference = 0.78%

  8. Constraints

  9. Legacy Links

  10. Scenarios Tested

  11. Scenario 1. Baseline - State

  12. Scenario 2. Most Structured - State

  13. Scenario 3. Least Structured - State

  14. Scenario 4. Budget Increase400% - State

  15. Scenario 5. Budget split25-75%State

  16. Scenario 6. LK (legacy links) Model - State

  17. Scenario 7. LK (new choice set) Model - State

  18. Scenario 1.Baseline - Counties

  19. Scenario 2. Most Structured - Counties

  20. Scenario 3. Least Structured - Counties

  21. Scenario 4. Budget Increase400% - Counties

  22. Scenario 5. Budget split25-75%Counties

  23. Scenario 6. LK (legacy links) Model - Counties

  24. Scenario 7. LK (new choice set) Model - Counties

  25. New Link Construction

  26. Link Expansion

  27. MOE: Accessibility

  28. MOE:Trip time

  29. MOE: Trip length

  30. MOE: VKT

  31. MOE: VHT

  32. As budget rises: vkt rises Network expands Accessibilityincreases Users spend less time on the road vht declines Future Work: Reduce Step length - five year model to one year model Reasons: To test an evolutionary model of network growth Only a percentage of work trips would change destinations in a given year Finer level of resolution Conclusions
