  • Description:
    The Access Board, with authority to enforce provisions of the American Disabilities Act (ADA), initially determined

    that roundabouts are not accessible by blind pedestrians and drafted proposed guidelines to require pedestrian

    signals at all roundabouts. More recently, the Access Board proposed final guidelines requiring pedestrian signals

    at all roundabouts with two or more lanes. It is possible that if these guidelines become Federal regulations through

    the Federal rule making process, and low-cost pedestrian signals are not developed, the growth of roundabouts

    could diminish greatly throughout Kansas and the USA. This will, in effect, deny motorists and public transportation

    organizations a safe, cost-effective means of intersection traffic control which potentially could result in many lives not

    saved and injuries not prevented. It has been projected that when stop controlled and signal controlled intersections

    are replaced by roundabouts there is a 76% reduction in injury crashes and a projected 90% decrease in fatalities.

    Kansas has been a national leader in design and construction of roundabouts and Kansas motorists would suffer a

    loss of these safety benefits if roundabout growth were slowed or halted. Roundabouts also have proven benefits

    in reduction of intersection delay and stopping as well as reduction in air pollution. These benefits could be lost or

    diminished as well.
