__Figure 2: Economic Framework for Estimating Benefits from
Changes in Generalized Access Cost__

This graph shows a hypothetical
demand curve for facility "*k*." The *x* axis is labeled "Number of
Facility *k* Uses Per Period" and the *y* axis is labeled
"Generalized Facility *k *Access and Use Cost." The demand curve for
facility *k* slopes downward from left to right. The graph shows that
when the time it takes to access facility *k* goes down from point P_{0}
to P_{1} on the *y* axis due to accessibility improvements from
the proposed regulations, then the number of uses by persons with disabilities
increases from point Q_{0} to Q_{1 }on the *x* axis. The
result is an increase in user benefits. Total user benefits are depicted as a
shaded rectangular area under the demand curve bordered by the points [P_{0}
a b P_{1}], where point *a* on the demand curve is located at the
intersection of P_{0} and Q_{0}, and point *b* on the
demand curve is the located at the intersection of P_{1 }and_{ }Q_{1.}
