Bolduc, Smiley & Associates, Inc. is responding to the request for comments about the referenced guidelines that were published in the Federal Register on Monday, June 17, 2002.  We are a professional transportation engineering firm in Phoenix, AZ.
 
In general, we are respectfully recommending that the Access Board not adopt the proposed requirements for the following subjects.  Further research and joint discussions with the professionals who deal with pedestrian, bicycle and vehicular movements on public rights-of-way are highly recommended, as well discussions with representatives of the National Federation of the Blind.
 
The subjects, along with brief comments are shown below.
 
Pedestrian Signal Phase Timing
A walking speed of 3.0 feet per second is not safe and is not reasonable everywhere.  Currently professional transportation engineers adjust walking speeds based upon users requirements.
 
Pedestrian Activated Crossing Signals at each Roundabout Crosswalk and Right or Left Turn Slip Lanes
This requirement, while undoubtedly well intentioned, unfortunately has the very real potential to be a primary cause of thousands of rear-end crashes and substantially increase congestion and delay.  It is my understanding that the National Federation of the Blind (NFB) and the Rehabilitation Services Administration (RSA) of the U.S. Department of Education both strongly support proper orientation and mobility training over this sort of unnecessary assistive device.
 
Accessible Pedestrian Signal Systems
It is not justified everywhere that “push buttons be equipped with a locator tone integrated into the signaling device to indicate that pedestrian activation is necessary and to identify the location of the push button”.  The professional transportation engineers currently cooperate with the crossing needs for vision impaired pedestrians when they are made aware of specific locations needing special attention.
 
Roundabout Barriers
The draft guidelines would require a continuous barrier along the street side of the sidewalk where pedestrian crossing is prohibited.  This requirement is unsafe, unreasonable, not justified and unsupported by either research or the NFB or RSA.
 
Please consider these comments before moving forward with the proposed requirements.
 
Sincerely,
 
Stephen L. Bolduc, P.E.
