What are APS? Audible pedestrian signals (APS) provides audible and/or vibrotactile information coinciding with visual pedestrian signals to let pedestrians who are blind know precisely when the WALK interval begins. This information is useful in analyzing an intersection and preparing to cross.
Pedestrians who know when the crossing interval begins will be able to start a crossing before turning cars enter the Intersection and can complete a crossing with less delay. Audible signals can also provide directional guidance, which is particularly useful at non-perpendicular intersections and at wide multi-lane crossings. (source: US Access Board[link 1]
