What role do audible cues play in traffic signals?

Audible cues play a crucial role in traffic signals by providing important information to pedestrians, particularly those who are visually impaired. These cues can include sounds that indicate when it is safe to cross the street or alert pedestrians to changing signal statuses. This auditory feedback allows individuals to navigate intersections more safely and independently, reducing the risk of accidents. The implementation of audible cues is an integral part of making transportation systems more accessible and inclusive for everyone, thereby enhancing pedestrian safety overall.
