  1. Cycling ScotlandRevamping Cycle Design Guidelines with New Innovations Photo by Patrick Lingwood

  2. ProWalk/ProBike Revamping Cycle Design Guidelines with New Innovations Presented by: Tom Bertulis, PE Engineering Manager Cycling Scotland September 6, 2006

  3. Presentation Outline • Part I: Background to the Guidelines

  4. Presentation Outline • Part I: Background to the Guidelines • Part II: Changes to the Guidelines

  5. Presentation Outline • Part I: Background to the Guidelines • Part II: Changes to the Guidelines • Part III: New Innovations

  6. Part I Background to the Guidelines

  7. Who do we have here today?

  8. A story …

  9. Design Manual for Roads and Bridges

  10. Manual for Streets Guidelines on Urban Design Manual for Streets

  11. Cycle Friendly Infrastructure (CFI)

  12. Cycle Friendly Infrastructure (CFI)

  13. Cycle Friendly Infrastructure (CFI) • First published in 1996

  14. Cycle Friendly Infrastructure (CFI) • First published in 1996 • “Time for an update!”

  15. My role was: • as a consultant • reviewing the guidelines • submitting comments • representing the devolved state of Scotland.

  16. Part II Changes to the Guidelines

  17. Changes to the Guidelines • Cyclist’s Dynamic Envelope • Maintenance • Advanced Stop Lines (ASL’s) • Side Road Crossings • Access Control • Invisible Infrastructure

  18. How much space does a bicyclist need on the road?

  19. Cyclist’s Dynamic Envelope

  20. Cyclist’s Dynamic Envelope

  21. Cyclist’s Dynamic Envelope

  22. Maintenance • Create a maintenance hotline • Inspect by bicycle • Budget early for maintenance

  23. Maintenance This handy maintenance checklist will be included

  24. Advanced Stop Lines (ASL’s) • No adverse impacton traffic capacity • Results in 25-35% accidentreduction for cyclists • Inexpensive

  25. Advanced Stop Lines

  26. Advanced Stop Lines

  27. Are cyclists safer on off-road cycle paths?

  28. The short answer:

  29. No. (the long answer: it depends)

  30. in the Hierarchy of Solutions …

  31. … providing cycle paths are your last choice Hierarchy of Solutions (1) Traffic Reduction (2) Traffic Calming (3) Intersection Treatment (4) Roadway Redistribution (5) Segregated Facilities First Priority Last Priority

  32. Why are they not safer?

  33. Why are they not safer?

  34. Side Road Crossing = danger! Michael Ronkin

  35. Bend In

  36. In Line

  37. In Line Rob Marshall

  38. In Line Rob Marshall

  39. Bend Out

  40. Bend Out Patrick Lingwood

  41. When should you use access control?
