Curb
Ramps – American with Disabilities Act
Since the 1970s,
city planners have struggled with the requirement to install curb
ramps at all street intersections. A necessary addition to the
right-of-way, curb ramps in American with Disabilities Ac, facilitate
smoother travel for wheelchair users by effectively removing the
curb and providing a gradual transition from sidewalk to roadway.

Unfortunately,
as useful and liberating as curb ramps prove, they are equally
as confusing and dangerous for the visually impaired. Prior to
the implementation of curb ramps, visually impaired pedestrians
used the drop-off edge of the curb line to distinguish the boundary
between the sidewalk and vehicular area. With a gradual slope
and no curb line to mark the edge of the road, curb ramps are
a major source of uncertainly for those with limited to no vision.
As a compromise
between the wheelchair community and the visually impaired, a
strip of truncated dome detectable warnings are mandated on all
curb ramps. American with Disabilities Ac requires 24” of
truncated domes back from the depressed curb spanning the full
width of the ramp which is perceived adequate coverage to effectively
alert visually impaired pedestrians without creating a hazardous
or painful bumpy surface for wheelchair users.
The Americans
with Disabilities Act attempts to balance the interests of all
disability groups and other various stakeholders. With years of
research behind the current legislation, city planners can be
confident that today’s curb ramp requirements maintain a
positive equilibrium between the two parties most affected.
