11B-810 TRANSPORTATION FACILITIES
Stations shall not be designed or constructed so as to require persons with disabilities to board or alight from a vehicle at a location other than one used by the general public.
Bus boarding and alighting areas shall comply with Section 11B-810.2.
[2010 ADAS] Advisory 810.2 Bus Boarding and Alighting Areas. At bus stops where a shelter is provided, the bus stop pad can be located either within or outside of the shelter.
Bus stop boarding and alighting areas shall have a firm, stable surface.
Bus stop boarding and alighting areas shall provide a clear length of 96 inches (2438 mm) minimum, measured perpendicular to the curb or vehicle roadway edge, and a clear width of 60 inches (1524 mm) minimum, measured parallel to the vehicle roadway.
U.S. Access Board's Note to Reader:
The Department of Transportation's ADA Standards indicate that compliance is required to the extent construction specifications are within a public entity's control:
[ADA Title II - Public Transportation] 810.2.2 Dimensions. 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.
DIMENSIONS OF BUS BOARDING AND ALIGHTING AREAS
Bus stop boarding and alighting areas shall be connected to streets, sidewalks, or pedestrian paths by an accessible route complying with Section 11B-402. Newly constructed bus stop boarding and alighting areas shall provide a detectable transition between the boarding/alighting area and the roadway; the detectable transition shall consist of a curb with the face sloped at 35 degrees maximum from vertical or detectable warnings complying with Sections 11B-705.1.1 and 11B-705.1.2.4.
Parallel to the roadway, the slope of the bus stop boarding and alighting area shall be the same as the roadway, to the maximum extent practicable. Perpendicular to the roadway, the slope of the bus stop boarding and alighting area shall not be steeper than 1:48.
Bus shelters shall provide a minimum clear floor or ground space complying with Section 11B-305 entirely within the shelter. Bus shelters shall be connected by an accessible route complying with Section 11B-402 to a boarding and alighting area complying with Section 11B-810.2.
Bus route identification signs shall comply with Sections 11B-703.5.1 _|Finish and Contrast|_ through 11B-703.5.4 _|Character Proportions|_, and Sections 11B-703.5.7 _|Stroke Thickness|_ and 11B- 703.5.8 _|Character Spacing|_. In addition, to the maximum extent practicable, bus route identification signs shall comply with Section 11B-703.5.5 _|Character Height|_.
Exception: Bus schedules, timetables and maps that are posted at the bus stop or bus bay shall not be required to comply.
Rail platforms shall comply with Section 11B-810.5.
Rail platforms shall not exceed a slope of 1:48 in all directions.
Exception: Where platforms serve vehicles operating on existing track or track laid in existing roadway, the slope of the platform parallel to the track shall be permitted to be equal to the slope (grade) of the roadway or existing track.
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 (203 mm) minimum above top of rail.
Exception: Where vehicles are boarded from sidewalks or street-level, low-level platforms shall be permitted to be less than 8 inches (203 mm).
U.S. Access Board's Note to Reader:
The Department of Transportation's ADA Standards note permitted alternatives where compliance is not operationally or structurally feasible in light rail, commuter rail, or intercity rail systems:
[ADA Title II - Public Transportation] 810.5.3 Platform and Vehicle Floor Coordination. 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).
[2010 ADAS] Advisory 810.5.3 Platform and Vehicle Floor Coordination. The height and position of a platform must be coordinated with the floor of the vehicles it serves to minimize the vertical and horizontal gaps, in accordance with the ADA Accessibility Guidelines for Transportation Vehicles (36 CFR Part 1192). The vehicle guidelines, divided by bus, van, light rail, rapid rail, commuter rail, intercity rail, are available at http://www.access-board.gov/. The preferred alignment is a high platform, level with the vehicle floor. In some cases, the vehicle guidelines permit use of a low platform in conjunction with a lift or ramp. Most such low platforms must have a minimum height of eight inches above the top of the rail. Some vehicles are designed to be boarded from a street or the sidewalk along the street and the exception permits such boarding areas to be less than eight inches high.
Rail station signs shall comply with Section 11B-810.6.
[2010 ADAS] Advisory 810.6 Rail Station Signs Exception. Emerging technologies such as an audible sign system using infrared transmitters and receivers may provide greater accessibility in the transit environment than traditional Braille and raised letter signs. The transmitters are placed on or next to print signs and transmit their information to an infrared receiver that is held by a person. By scanning an area, the person will hear the sign. This means that signs can be placed well out of reach of Braille readers, even on parapet walls and on walls beyond barriers. Additionally, such signs can be used to provide wayfinding information that cannot be efficiently conveyed on Braille signs.
Where signs identify a station or its entrance, at least one sign at each entrance shall comply with Section 11B-703.2 _|Signs; Raised Characters|_ and shall be placed in uniform locations to the maximum extent practicable. Where signs identify a station that has no defined entrance, at least one sign shall comply with Section 11B-703.2 and shall be placed in a central location.
Lists of stations, routes and destinations served by the station which are located on boarding areas, platforms, or mezzanines shall comply with Section 11B-703.5 _|Signs; Visual Characters|_. At least one tactile sign identifying the specific station and complying with Section 11B-703.2 _|Signs; Raised Characters|_ shall be provided on each platform or boarding area. Signs covered by this requirement shall, to the maximum extent practicable, be placed in uniform locations within the system.
Exception: Where sign space is limited, characters shall not be required to exceed 3 inches (76 mm).
[2010 ADAS] Advisory 810.6.2 Routes and Destinations. Route maps are not required to comply with the informational sign requirements in this document.
Stations covered by this section shall have identification signs complying with Section 11B-703.5 _|Signs; Visual Characters|_. Signs shall be clearly visible and within the sight lines of standing and sitting passengers from within the vehicle on both sides when not obstructed by another vehicle.
[2010 ADAS] Advisory 810.6.3 Station Names. It is also important to place signs at intervals in the station where passengers in the vehicle will be able to see a sign when the vehicle is either stopped at the station or about to come to a stop in the station. The number of signs necessary may be directly related to the size of the lettering displayed on the sign.
Where public address systems convey audible information to the public, the same or equivalent information shall be provided in a visual format.
Where clocks are provided for use by the public, the clock face shall be uncluttered so that its elements are clearly visible. Hands, numerals and digits shall contrast with the background either light-on-dark or dark-on-light. Where clocks are installed overhead, numerals and digits shall comply with Section 11B-703.5.
Where provided, escalators shall comply with the sections 184.108.40.206.6 and 220.127.116.11.5 of ASME A17.1 and shall have a clear width of 32 inches (813 mm) minimum.
Exception: Existing escalators in key stations shall not be required to comply with Section 11B-810.9.
