Accessible pedestrian signals (APS), formerly known as audible pedestrian signals, advise pedestrians who are blind, visually impaired, or deaf-blind when they have the right-of-way to cross at a signalized intersection and in which direction they may cross the intersection. The City of Toronto currently has 518 signalized intersections equipped with APS. City staff is working towards retrofitting additional signalized intersections with APS in 2012.
