What is an Accessible Pedestrian Signal (APS) ?

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

Features•Locator tone: provides info regarding existence and location of ped pushbuttons•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

Ped-actuated Pedestrian Crossing

Pre-timed & Rest-in-Walk Pedestrian Crossing

• Pushbutton activates accessible ped signals only. WALK interval is on recall.
