This is to provide comments about Audible Traffic Signals as well as Detectable Warning Strips.

In most cases Audible traffic Signals are not needed for blind persons to safely cross the intersections. In fact they may be a distraction. The added noise of the Audible Signal may mask other traffic or environmental noises which are necessary clues for the safe navigation of the intersection. While there may be some occasions where there are not sufficient clues where these Signals may be helpful, I believe they are few and far between.

When there are places such as medians or islands where there are no other detectable markings, Detectable Warning Strips could be of use: however, in most cases, proper use of a cane or dog guide should provide quite adequate warning for the blind traveler.

If it is decided that there needs to be audible Traffic signals on almost every corner, I feel, this would be a tremendous waste of limited funds. The funds which would be allocated to these projects might be more effectively used for a widespread educational program to better inform both drivers and pedestrians of proper safety rules.

Sincerely
