Which of these is a feature of audible pedestrian crosswalk signals apex?

An audible pedestrian crosswalk signal is a feature that helps visually impaired pedestrians navigate safely across the streets. These signals emit a sound, usually a beeping or chirping noise, to alert pedestrians when it is safe to cross. This helps ensure that pedestrians with visual impairments can cross the street with confidence and reduce the risk of accidents. Audible pedestrian crosswalk signals are typically installed at intersections or crosswalks where there is a high volume of pedestrian traffic. They are an important accessibility feature that promotes inclusivity and safety in urban environments.
