Currently, around 65 percent of all traffic lights in the City of Wien are equipped with additional facilities for visually impaired and blind people. In addition to acoustic signals, tactile signs and floor grooves help you cross the street safely.
Volunteers of the Hilfsgemeinschaft der Blinden und Sehschwachen Österreichs (Austrian Association for the Blind and Visually Impaired) check ATA (Akustisch-Taktile-Ampel) systems, often called "traffic lights for the blind", once a month. These are the small boxes on many traffic light poles that make a rhythmic noise. They have a push button at the bottom, and when you push that, a loud, rapid "Tac, Tac, Tac" sounds as soon as it turns green.
This way, a blind pedestrian hears that he can now cross over.976 traffic lights have to be reviewed every year
