I am writing in support of the PROWHAC report.  As a vision impaired senior citizen I find city travel (which I must undertake almost daily since I live in Pittsburgh and travel to many cities in the Eastern United States) more and more challenging. Heavily trafficked streets can be very hazardous if one loses focus even temporarily. I am always please therefore when I hear that audible signals have been installed ANYWHERE. Of course such signals cannot be installed everywhere both because they are not needed everywhere and because it would eventually prove costwise prohibitive.

Just as walk signs, white/yellow lines, arrows, etc. facilitate movement for both pedestrians and motorists with sight, so can audible signals and detectable warnings at railroad and subway stops make travel more safe for blind or vision impaired

I endorse the work of the Access Board.

Sincerely,

A. H. Evancic
