Audible Pedestrian Signs Unveiled In New York

The city debuted the installation of audible pedestrian signals at 25 intersections throughout the city on Wednesday. The new system will aid pedestrians, specifically the visually impaired and elderly cross streets.

21 of the 25 intersections are already equipped with the devices, which release a clicking sound in order to alert pedestrians when the 'walk' phase is available to them.

Transportation Commissioner Janette Sadik-Khan was joined by city council members at West 23rd Street and 7th Avenue for the announcement on Wednesday. The intersection is known for its high volume traffic and busy movement.

Sadik-Khan explained the significance of the new system:

Audible signals are literally sound investments that will help improve the safety and quality of life for the most vulnerable New Yorkers who use our streets. My dad was blind, so I know firsthand the challenges that visually impaired people face every single day.

The intersections can be found at the following locations:

East 25th Street (between 3rd and Lexington Avenues)
7th Avenue and West 32nd Street

Queens and Woodhaven Boulevards
57th Avenue and Marathon Parkway

Morris Park Avenue pedestrian crossing @ Albert Einstein College of Medicine

Adams Street Pedestrian Crossing, midblock between Fulton and Johnson Streets
Nevins and Fulton Streets at Flatbush Avenue
Adams Street/Boerum Place and Livingston Streets
Adams Street and Atlantic Avenue
