Under Department of Transportation (DOT) Americans with Disabilities Act (ADA) regulations at 49 C.F.R. Section 37.131(a)(1)(i), transit entities must “provide complementary paratransit service to origins and destinations within corridors with a width of three-fourths of a mile on each side of each fixed route.” The measurement to destinations within the three-fourths of a mile corridor on each side of a fixed route is measured “as the crow flies” and does not vary based upon driving distance.
