Appendix A to Part 37 - Modifications to Standards for Accessible Transportation Facilities
49:1.0.1.1.27.10.43.1.21 : Appendix A
Appendix A to Part 37 - Modifications to Standards for Accessible
Transportation Facilities
The Department of Transportation, in § 37.9 of this part, adopts
as its regulatory standards for accessible transportation
facilities the revised Americans with Disabilities Act Guidelines
(ADAGG) issued by the Access Board on July 23, 2004. The ADAGG is
codified in the Code of Federal Regulations in Appendices B and D
of 36 CFR part 1191. Note the ADAAG may also be found via a
hyperlink on the Internet at the following address:
http://www.access-board.gov/ada-aba/final.htm. Like all
regulations, the ADAAG also can be found by using the electronic
Code of Federal Regulations at
http://www.gpoaccess.gov/ecfr. Because the ADAAG has been
established as a Federal consensus standard by the Access Board,
the Department is not republishing the regulations in their
entirety, but is adopting them by cross-reference as permitted
under 1 CFR 21.21(c)(4). In a few instances, the Department has
modified the language of the ADAAG as it applies to entities
subject to 49 CFR part 37. These entities must comply with the
modified language in this Appendix rather than the language of
Appendices B and D to 36 CFR part 1191.
206.3 Location - Modification to 206.3 of Appendix B to 36 CFR Part
1191
Accessible routes shall coincide with, or be located in the same
area as general circulation paths. Where circulation
paths are interior, required accessible routes shall
also be interior. Elements such as ramps, elevators, or other
circulation devices, fare vending or other ticketing areas, and
fare collection areas shall be placed to minimize the distance
which wheelchair users and other persons who cannot negotiate steps
may have to travel compared to the general public.
406.8 - Modification to 406 of Appendix D to 36 CFR Part 1191
A curb ramp shall have a detectable warning complying with 705.
The detectable warning shall extend the full width of the curb ramp
(exclusive of flared sides) and shall extend either the full depth
of the curb ramp or 24 inches (610 mm) deep minimum measured from
the back of the curb on the ramp surface.
810.2.2 Dimensions - Modification to 810.2.2 of Appendix D to 36
CFR Part 1191
Bus boarding and alighting areas shall provide a clear length of
96 inches (2440 mm), measured perpendicular to the curb or vehicle
roadway edge, and a clear width of 60 inches (1525 mm), measured
parallel to the vehicle roadway. Public entities shall ensure that
the construction of bus boarding and alighting areas comply with
810.2.2, to the extent the construction specifications are within
their control.
810.5.3 Platform and Vehicle Floor Coordination - Modification to
810.5.3 of Appendix D to 36 CFR Part 1191
Station platforms shall be positioned to coordinate with
vehicles in accordance with the applicable requirements of 36 CFR
part 1192. Low-level platforms shall be 8 inches (205 mm) minimum
above top of rail. In light rail, commuter rail, and intercity rail
systems where it is not operationally or structurally feasible to
meet the horizontal gap or vertical difference requirements of part
1192 or 49 CFR part 38, mini-high platforms, car-borne or
platform-mounted lifts, ramps or bridge plates or similarly
manually deployed devices, meeting the requirements of 49 CFR part
38, shall suffice.
EXCEPTION: Where vehicles are boarded from sidewalks or
street-level, low-level platforms shall be permitted to be less
than 8 inches (205 mm).
