To Whom It May Concern:
My first experience with audible signals took place up in Littleton, Colorado.
The problem it presented was it distracted me from attending to my ability to
cross the street safely.
Audible signals may be beneficial when a street crossing is complex, such as
crossing ten lanes or diagonal crossings. A placement on a difficult
intersection would assist a blind person in performing a safe crossing. However,
on a simple street intersection, audible signals on each corner would confuse
the blind pedestrian and may cause bodily harm.
