7 What is an Accessible Pedestrian Signal (APS) ?
A device that communicates information about pedestrian timing at signalized intersections to the visually impaired.

8 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
