Advocates for the blind are raising awareness of a technology to help make crossings safer.

The Accessible Pedestrian Signal, or APS, gives audio cues or a series of beeps to allow the visually impaired to know when the street is safe to cross.

Advocates challenged sighted people Tuesday to cross a busy White Plains intersection while blindfolded. They say their next goal is to get lawmakers to take the same challenge, hoping they might walk away with greater insight into their daily challenges.

The device costs about $3,000 to install at a crosswalk.
