Temporary Traffic Control

Messages for audible information devices

Audible information devices are intended to provide information to pedestrians with visual disabilities that is equivalent to visual signing for notification of sidewalk closures and to indicate a temporary path around a construction area, using a speech message.

Researchers tested nine messages to identify key components or phrases that should be used within audio messages to provide visually impaired pedestrians with information regarding work zones that would affect their travel.  The example messages are provided here are based on that research, with some modifications and additional suggestions by Accessible Design for the Blind.
