F Is For Fantastic Charlier

  1. 1. F is for fantastic New Directions in Transportation LOS Jim Charlier Charlier Associates, Inc.
  2. 2. This Morning Jim Charlier, Charlier Associates Introduction to LOS Ronald Milam, Fehr & Peers State of the Practice Mark Jackson, City of Fort Collins Implementation Experience Discussion, Q & A
  3. 3. Introduction: The Issue What is LOS? Why do we do things this way? How is it working?
  4. 4. What is LOS? Road supply performance measure Measurement: Volume / capacity (V/C) Average delay Current and forecast
  5. 5. Traditional Definition A= Free flow B=Reasonably free flow C=Stable flow D=Approaching unstable flow E=Unstable flow F=Forced or breakdown flow
  6. 6. Measured For: Links (segments of roads) Intersections Averaged along corridors Average across a cordon line Averaged in districts
  7. 7. (Traffic) LOS Used For: Sizing of Roads & Streets Corridor studies Roadway design Right of way Traffic Impact Studies Entitlement of development Sub –area planning Growth Management Systems Concurrency/adequate public facilities
  8. 8. Introduction: The Issue What is LOS? Why do we do things this way? How is it working?
  9. 9. From no roads…
  10. 10. Major Phases in 1893 New U.S. History Frontier Millennium Closes Expansion Exploration, Initial Settlement of Cities & ??? Suburbs 300 millions 200 100 population 1600 1700 1800 1900 2000
  11. 11. Our Learned Approach Build it quick, build it cheap Faster, straighter, wider = better Don’t worry about land uses Just get ‘er done Role of LOS How big should the “pipes” be? What has the highest priority?
  12. 12. Supply Side Focus
  13. 13. “Oops”
  14. 14. Introduction: The Issue What is LOS? Why do we do things this way? How is it working?
  15. 15. Not Very Well Congestion alleviation = sprawl We need networks, not corridors Streets are more than “facilities” Streets should be multimodal
  16. 16. Have you ever noticed...? Predict Growth Forecast Traffic Widen Streets
  17. 17. Induced Traffic
  18. 18. Types of Induced Traffic Changes in travel route ………………… Immediate Changes in mode of travel ……………. < 6 months Changes in time of travel ……………. < 6 months Changes in amount of travel ..…….. < 6 months Changes in origins & destinations…… < 10 years
  19. 19. % of new capacity consumed by induced traffic… 100% Long Term: five to 10 years 80% 60% Short Term: less than five years 40% 20%
  20. 20. Are we responding to traffic growth… …or are we causing it? “Project & Provide”
  21. 21. Effects of “Project & Provide” High rates of driving High risk of accidents Lower rates of walking High of air pollution, esp. ozone High levels of GHG emissions No reduction in congestion delay
  22. 22. Road Building Has Not Reduced Delay
  23. 23. What we’ve learned about “congestion alleviation” 1. Congestion Alleviation = Sprawl 2. Sprawl = More Traffic 3. Traffic Forecasting ≠ Planning
  24. 24. Not Very Well Congestion alleviation = sprawl We need networks, not corridors Streets are more than “facilities” Streets should be multimodal
  25. 25. Networks not Corridors
  26. 26. Poor Connectivity Means: “You can’t get there from here . . .” (without driving on an arterial)
  27. 27. Lakewood, CO
  28. 28. Aurora
  29. 29. Focusing on Corridors Redmond, WA
  30. 30. Facility-Centered Approach Redmond, WA
  31. 31. Not Very Well Congestion alleviation = sprawl We need networks, not corridors Streets are more than “facilities” Streets should be multimodal
  32. 32. St. Louis Region
  33. 33. Newbury, Boston
  34. 34. Neighborhood Abutting Abutting Property Property Street
  35. 35. Neighborhood Street Abutting Property
  36. 36. Lakewood, CO
  37. 37. Boulder
  38. 38. Portland
  39. 39. You can’t design a street like this… Oahu
  40. 40. …and expect this to result. Boulder
  41. 41. Anywhere, USA
  42. 42. Berkeley, CA
  43. 43. Not Very Well Congestion alleviation = sprawl We need networks, not corridors Streets are more than “facilities” Streets should be multimodal
  44. 44. Multimodal Streets?
  45. 45. Multimodal Streets
  46. 46. This Morning Jim Charlier, Charlier Associates Introduction to LOS Ronald Milam, Fehr & Peers State of the Practice Mark Jackson, City of Fort Collins Implementation Experience Discussion, Q & A
