I am writing to oppose both audible traffic signals, (APS) and detectable
warnings' installations at all intersections in our nation. These would be of
more use to travelers who are blind if each intersection thought by someone to
have a problem were considered individually both by the traveler and by his/her
city officials to address difficulties with the intersection.
Blanket installation of either APS signals or detectable warnings at all
walk/don't walk intersections could prove to be hazardous to blind travelers.
Overall installation would also be extremely expensive and perhaps difficult for
up-keep and/or maintenance if cement formations of certain dectectable warnings
were subjected to long-term weathering.
Thank you for your attention.
