A device that communicates information about pedestrian timing at signalized intersections to the visually impaired.

Push button: places a call for the “WALK” signal and activates the APS
Vibro-tactile arrow: indicates the direction of travel and emits a distinguishable tone as it vibrates during “WALK” phases

Pushbutton activates accessible ped signal and the WALK interval

10. Pre-timed & Rest-in-Walk Pedestrian Crossing
Pushbutton activates accessible ped signals only. WALK interval is on recall.
