which of these is a feature of audible pedestrian crosswalk signals?\na. emergency instructions\nb. pedestrian tracking\nc. button location signaling\nd. responses to voice commands
Answer
Brief Explanations:
Audible pedestrian crosswalk signals are designed to assist visually - impaired pedestrians. Button location signaling helps them find the push - button for the crosswalk signal. Emergency instructions are not a typical feature. Pedestrian tracking is not part of their function and they do not respond to voice commands.
