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).
