Abstract
Recently, Audible Pedestrian Signals (APS) that provide audible information (to pedestrians who are blind) from pushbutton location have been introduced in the United States. In some of these pushbutton integrated signals, speech messages are being used to indicate the walk interval information, as well as additional information when the pedestrian pushbutton is pushed during the "don't walk" and "flashing don't walk" intervals. This research on speech messages for APS was undertaken to develop recommendations based on data from stakeholders to form the basis for the establishment of recommended practice for the structure and content of walk messages and pushbutton messages for directly audible accessible pedestrian signals.
