9. Transportation Institute Texas Transportation Institute Texas Information Formats Barrier and/or Audible information to provide alternate route

10. Transportation Operations Group Transportation Institute Texas  MUTCD 6D.01 “The most desirable way to provide information to pedestrians with visual disabilities that is equivalent to visual signage for 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.”

11. Transportation Operations Group Transportation Institute Texas  Sponsored by TxDOT  Evaluation of information components  Message Types › Alternate Route › Warning

12. Transportation Operations Group Transportation Institute Texas  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

13. Transportation Operations Group Transportation Institute Texas  Driveways Influence Navigation Ability  Street Names Not Critical  Path Details are Reassuring
