Audible beaconing is the use of an audible signal in such a way that blind pedestrians can home in on the signal coming from the target corner as they cross the street.

Hello. This question is incomplete. The full question is:

"Which of these is a feature of audible pedestrian crosswalk signals?  A. Emergency instructions  B. Responses to voice commands  C. Intersection information  D. Pedestrian tracking"

C. Intersection information

Explanation:

The audible signal is activated by a button and beeps to inform the blind or visually impaired person when the signal is open for pedestrian crossing. That way, the person can cross the street safely. Based on this, we can say that the main function of this type of signal is to provide intersection information.

The equipment is for the exclusive use of the visually impaired and people with low vision, allowing these people to be able to walk safely and autonomously.
