Beyond the curb line, a clear space of 48 inches
(1220 mm) minimum by 48 inches
(1220 mm) minimum shall be provided within the width of the crosswalk and wholly outside the parallel vehicle travel lane

MASS HIGHWAY
Dear Sirs:
We are responding to the proposed rule changes in the Americans with Disabilities Act (ADA) Accessibility Guidelines for Buildings and Facilities; Architectural Barriers Act (ABA) Accessibility Guidelines; Public Rights-of-Way, published in the Federal Register in Monday, June 17, 2002.
We have reviewed the comments made by the AASHTO Committee on Highways, which have been submitted to you, and concur with them. In addition to those comments, we have one major additional concern which we believe was inadequately addressed by the committee.
Section 1103.3 Clear Width
This section provides for a 48-inch path of travel for sidewalks excluding the curb.
To obtain a 48-inch path of travel requires a minimum sidewalk width of 54 inches
We strongly urge continuation of the 36-inch path of travel and the reduction of the clear width of the pedestrian route to 32 inches
Sincerely,
Thomas F. Broderick, P.E.
Chief Engineer

Subject: ADA Public ROW Guidelines Comments
The following are comments that I had regarding the "Draft Guidelines for Accessible Public Rights-of-Way".
Under the Discussion of Provisions section, I had the following comments:
1. General Scoping: New Construction, Alterations, and Additions 1102, there should be a distinction between "minor" and "major" alterations added. There should be an exception made to this provision if the total cost of the accessibility features exceeds the total cost of the alteration project.
2. Accessible Elements and Spaces: Scoping and Technical Requirements, Minimum Clear Width 1103.3, I believe that the minimum clear width should be 36 inches
3. Accessible Elements and Spaces: Scoping and Technical Requirements, Surface Gaps at Rail Crossings 1103.7, the guideline does not clarify if the local authority or the rail road is responsible for complying with the gap and the detectable warning requirements. The local authority, in most cases, does not own or have control over the train tracks or the ground surface adjacent to the tracks.
4. Accessible Elements and Spaces: Scoping and Technical Requirements, Common Elements 1104.3, the minimum clear width should be reduced from 48 inches to 36 inches
5. Accessible Elements and Spaces: Scoping and Technical Requirements, Detectable Warnings 1104.3.2, the guideline specifies that truncated domes be used as the minimum standard detectable warning device, however, truncated domes are a severe tripping hazard for visually impaired people.
6. Accessible Elements and Spaces: Other Requirements for Curbs, Ramps and Blended Transitions 1104.3.3 - 1104.3.7, in the last bullet, it specifies a clear space of 48 x 48 inches
7. Pedestrian Crossings: Crosswalks 1105.2, the crosswalk width should be the same as the MUTCD - 72 inches
8. Accessible Pedestrian Signal Systems 1102.8, 1106, it specifies, at intersections that allow pedestrian traffic, walk indicators should include additional audible and tactile indicators. I believe this should only be required at intersections that have marked pedestrian crosswalks and not at every intersection. Another option would be to require them at intersections that have crosswalks and/or sidewalks that allow pedestrian foot traffic. However, to require them at every intersection is unreasonable and cost prohibitive.
Under the Text of Draft Guidelines section, I had the following comments:
1. 1102.10 Stairs, the contrasting color strip should be marked with a contrasting color tone and not just a different color because visually impaired persons may not see color, but can more easily distinguish differences in color tone.
2. 1103.3 Clear Width, the minimum clear width should be 36 inches
3. 1104.2.1.3 Landing, a landing should be a minimum of 36 by 36 inches
4. 1104.2.2.3 Landing, a landing should be a minimum of 36 by 36 inches
5. 1104.3.1 Width, again the minimum width should be 36 inches
6. 1104.3.7 Clear Space, the minimum width should be 36 by 36 inches
7. 1108 Detectable Warning Surfaces, General, truncated domes are not a good device to use as a tactile warning device. For visually impaired persons, truncated dome can be a tripping hazard.
If you have any questions or need additional information, please let me know.
Thanks!
RESPONSES TO DRAFT GUIDELINES FOR ACCESSIBLE PUBLIC RIGHTS-OF-WAY DATED JUNE 17, 2002
DISCUSSION OF PROVISIONS
Additions and Alterations (1102.2)
1. Definition for "substantial reconstruction" open to subjectivity
2. Definition for "limited improvements" open to subjectivity
3. Who defines "technically infeasible"?
4. Who makes the determination on a case by case basis?
5. What is the potential cost for delays during the evaluation?
6. Delays and requirements will increase overall cost of doing business in public rights-of-way significantly
Surface Gaps at Rail Crossings ( 1103.7)
1. Detectable warnings for each track approach within the railroad rights-of-way would be whose responsibility to install and maintain?
Curb Ramps and Blended Transitions (1102.6, 1104)
1. The dual ramp requirement causes several issues at existing intersections and even more issues at new intersections. At existing intersections, not only will existing storm drains and utility poles pose a problem, but also where dual curb ramps can be installed a visibility issue for vehicular traffic will exist. Dual ramps force the installation at the terminus of a curb return. In turn, the crosswalk and stop bar have to match the curb ramps; therefore, installation of a 96" cross walk, 24" stop bar and the necessary spacing between will force the vehicle stop point behind the current visibility clips at intersections.
Perpendicular Curb Ramps (1104.2.1)
1. 48" X 48" level landings at the top of ramps will require additional rights-of-way purchases to accommodate. Clear space requirements will increase this need at intersections as well.
Detectable Warnings (1104.3.2)
1. Depending on the application, the truncated domes may still cause problems for wheel chair users.
Informational Signs and Warning Signs (1102.7.2)
1. It is unclear what the expectation is from the new guidelines as to what these signs are expected to provide for visually impaired pedestrians.
Pedestrian Crossing (1102.8, 1105)
1. Profile grades of 2 percent at intersection crosswalks are normally reasonable; however, in street conditions that have over 5 percent continuous grade, this requirement will have an overwhelming affect on construction cost for new and existing intersections.
Roundabouts (1105.6)
1. This guideline will all but eliminate the use of this method of continuous flow application due to cost and the fact that continuous flow would no longer be attainable.
Lori Chapin has reviewed the new ADA regulations you sent Keith from our perspective. For the most part, the new regulations would help clear up some issues from our perspective, assuming they would also be incorporated into the Texas Accessibility Standards which is what TDLR enforces. The few items we would like to include in comments you forward back to TEXITE or whatever procedure has been set up are attached. Please give me or Lori a call if you have questions. Thanks.
Leslie Salgado-Tamayo, October 28, 2002
Please find enclosed the comments we have on the Access Board's Draft Guidelines on Accessible Public Rights of Way. Please note that we have not commented on those items that do not affect our transit facilities. I hope that this is helpful to you in the process of preparing the new guidelines on public rights-of-way. Please call me at [...], should you have any questions or comments.
Sincerely,
Leslie Salgado-Tamayo
Chief, ADA and Special Projects,
Facilities Engineering Maryland Transit Administration
Maryland Transit Administration (MTA) - Comments on the
"Draft Guidelines for Accessible Public Rights-of-Way"
1102.2.2 Alterations. Where existing elements or spaces in the public right-of-way are altered, each altered element or space shall comply with the applicable provisions of Chapter 11.
EXCEPTION:In alterations, where compliance with applicable provisions is technically infeasible, the alteration shall comply to the maximum extent feasible.
MTA's comment
- What constitutes an "alteration"? We need more definite guidelines. This is not a new problem with ADAAG.
- We need a better definition of "maximum extent feasible". Is there a dollar amount? More guidance needed.
1102.3 Alternate Circulation Path. An alternate circulation path complying with1111 shall be provided whenever the existing pedestrian access route is blocked by construction, alteration, maintenance, or other temporary conditions.
MTA's comment
- Refer to comment under 1111.
1102.7 Pedestrian Signs. Signs for pedestrian use shall comply with 1102.7.
1102.7.1 Bus Route Identification. Bus route identification signs shall comply with 703.5.1 through 703.5.4, and 703.5.7 and 703.5.8. In addition, to the maximum extent practicable, bus route identification signs shall comply with 703.5.5. Bus route identification signs located at bus shelters shall provide raised and Braille characters complying with 703.2, and shall have rounded corners.
MTA's comment
- It is not clear if providing bus route identification signs, at bus shelters, in raised and Braille characters is required only where bus route identification signs in compliance with 703.5.5 are provided. If required, at bus shelters, what are the recommended placement locations, since shelters don't have doors?
1102.8 Pedestrian Crossings. Where a pedestrian crossing is provided, it shall comply with the applicable provisions of1105.
MTA's comment
- See comment under Section 1105.
1102.10 Stairs. Where provided, stairs shall comply with 504. Stair treads shall have a 2 inch
MTA's comment
- "2 inch
1103.3 Clear Width. The minimum clear width of a pedestrian access route shall be 48 inches
MTA's comment
- This increases the minimum clear width from 36 to 48 inches
1103.7 Surface Gaps at Rail Crossings. Where the pedestrian access route crosses rail systems at grade, the horizontal gap at the inner edge of each rail shall be constructed to the minimum dimension necessary to allow passage of railroad car wheel flanges and shall not exceed 2-½ inches (64 mm).
EXCEPTION: On tracks that carry freight, a maximum horizontal gap of 3 inch
MTA's comment
Allowing the 3-inch gap helps clear an ongoing problem where transit agencies provide their services via tracks owned by freight companies.
1104.2.1.3 Landing. A landing 48 inches
MTA's comment
- This reflects the new increased width of sidewalk (from 36 to 48 inches). This will result in increased construction costs and, in some cases require additional right-of-way. We recommend that you allow 36 inches
1104.2.2.3 Landing. A landing 48 inches
MTA's comment
- This reflects the new increased width of sidewalk (from 36 to 48 inches). This will result in increased construction costs and, in some cases require additional right-of-way. We recommend that you allow 36 inches
1104.2.2.4 Diverging Sidewalks. Where a parallel curb ramp does not occupy the entire width of a sidewalk, drop-offs at diverging segments shall be protected with a barrier.
MTA's comment
- What constitutes a drop-off where a "barrier" would be required?
1104.3.2 Detectable Warnings. Detectable warning surfaces complying with1108 shall be provided, where a curb ramp, landing, or blended transition connects to a crosswalk.
MTA's comment
- This is a new requirement that will create tripping hazards and the resulting liability as well as increased maintenance costs.
1104.3.7 Clear Space. Beyond the curb line, a clear space of 48 inches
MTA's comment
- Diagram needed in order to better understand this requirement.
1105.2 Crosswalks. Crosswalks shall comply with 1105.2.
1105.2.1 Width. Marked crosswalks shall be 96 inches
MTA's comment
- This is an increase of two feet over MUTCD's 72 inch
1105.2.2 Cross Slope. The cross slope shall be 1:48
MTA's comment
- Meeting this requirement may be highly unrealistic when dealing with existing roads or parking lots that are being upgraded.
1105.5 Pedestrian Overpasses and Underpasses. Pedestrian overpasses and underpasses shall comply with 1105.5.
1105.5.1 Pedestrian Access Route. Pedestrian overpasses and underpasses shall contain a pedestrian access route complying with1103.
1105.5.2 Running Slope. The running slope shall not exceed 1:20
1105.5.3 Approach. Where the approach exceeds 1:20
MTA's comment
- This new requirement will have major design, construction, maintenance and safety impacts on our agency. The need to have a limit to the maximum rise for a ramp is understandable. However, 60 inches
1111 Alternate Circulation Path
1111.1 General. Alternate circulation paths shall comply with 1111.
1111.2 Width. The alternate circulation path shall have a width of 36 inches
1111.3 Location. The alternate circulation path shall parallel the disrupted pedestrian access route, on the same side of the street.
MTA's comment
- Providing a 36 inch
