I am writing to express my support for the PROWAC's (Public Right of Way
Advisory Committee) recommendations on accessible pedestrian signals and
detectable warnings. I have visited cities in the United States that are in the
vanguard of giving information available to sighted pedestrians to non-sighted
pedestrians via audible signals. These signals are distinct and make it very
easy for non-sighted pedestrians to cross intersections with much greater
safety. I do not find these signals confusing and they do not interfer with
traffic noise, which is used by some non-sighted pedestrians
use as an indicator. I also think that these signals are a much more effective
means of determining whether it is safe to proceed than traffic noise. In very
large and busy intersections it is extremely difficult to discern the difference
in direction for traffice. Finally, with the recent introduction of electric and
gas and electric cars which make little or noise, it is imperative that another
means of notification other than traffic noise be instituted.
Thank you for taking my comments.
