  1. Assisting Handicapped Pedestrians Through Work Zones: Meeting the ADA Requirements Brooke R. Ullman, P.E. Texas Transportation Institute

  2. Pedestrians with disabilities • Mobility disabilities • Visual disabilities

  3. Visually Impaired Pedestrians

  4. What can cause problems? • Unexpected closure on “normal” route • Non-detectable route markings/delineation • Lack of barriers • Signs within a pathway

  5. Accessible Design for the Blind

  6. Accessible Design for the Blind Free of hazardous protruding objects?

  7. Route information in usable formats?

  8. Information Formats Barrier and/or Audible information to provide alternate route

  9. MUTCD Guidance • MUTCD 6D.01 “The most desirable way to provide information to pedestrians with visual disabilities that is equivalent to visual signagefor notification of sidewalk closures is a speech message provided by an audible information device.” • MUTCD 6F.13 “An audible information device is needed when the detectable barricade or barrier for an alternate channelized route is not continuous.”

  10. Audible Information Study • Sponsored by TxDOT • Evaluation of information components • Message Types • Alternate Route • Warning

  11. Audible Information Recommendations • Clearly State Intended Path • “Use Opposite Side of the Street” • “Sidewalk Is Open” • “In Street” • Use Blocks or Landmarks to Identify Travel Distance • Critical Elements • Initial Turning or Crossing Instruction • Distance to Follow Alternate Path

  12. Recommendations (con’t) • Driveways Influence Navigation Ability • Street Names Not Critical • Path Details are Reassuring

  13. Barrier Information • Detectable pathway edge • Detectable channelizing devices

  14. Not a good start…

  15. Mobility Impaired

  16. What can cause problems? • Inconsistent or unpassable surfaces • No accessible route at closure • Disconnect in accessibility • Path width

  17. Wide enough for passage?

  18. Improvements • Following slides show some improved examples • Ramps • Accessible paths

  19. Another view

  20. Conclusions • Visually Impaired • “Equivalent to Visual Signage” • Barrier • Audible • Mobility Impaired • Continuity • Access • Surfaces • Not an after thought!

  21. Resources and Information • MUTCD Part 6 • Draft Public Rights-of-Way Accessibility Guidelines • US Access Board Technical Assistance at (800) 872-2253 or row@access-board.gov • TTI Research on Pedestrians in Work Zones • http://tti.tamu.edu/documents/0-5237-P1.pdf • http://tti.tamu.edu/documents/0-5237-1.pdf

  22. Questions / Discussion • Thanks to Lois Thibault, US Access Board, and Janet Barlow, Accessible Design for the Blind, for many of the photos used. • Brooke Ullman • b-ullman@tamu.edu • Gerald (Jerry) Ullman • g-ullman@tamu.edu
