    RE: Draft Guidelines for Accessible Public Rights-of-Way

    The American Public Transportation Association (APTA) is pleased to respond to the Architectural and Transportation Barriers Compliance Board's (Access Board) draft guidelines addressing accessibility in the public right-of-way.

    About APTA

    APTA is a nonprofit international association of over 1,500 public and private member organizations including transit systems and commuter rail operators; planning, design, construction and finance firms; product and service providers; academic institutions, transit associations and state departments of transportation. APTA members serve the public interest by providing safe, efficient and economical transit services and products. Over ninety percent of persons using public transportation in the United States and Canada are served by APTA members.

    Comments

    APTA has been part of this rulemaking from its inception and will continue to participate in the development of guidelines related to accessibility in the public right-of-way. Indeed, since 1999, APTA has contributed its input to the Public Rights of Way Access Advisory Committee. Now, with the release of the draft guidelines, APTA has the following comments:

    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.

    Comment: Remove requirement for Braille and raised letter route identifications. It is common for transit agencies to change schedules and routes three or four times per year. Transit agencies also replace or install bus shelters often. For signs to withstand normal use, weather conditions and vandalism, it is necessary to make them of durable materials such as aluminum. This requires a separate die to be fabricated for each bus stop; the average cost of having dies fabricated begins at fifteen hundred dollars. In short, the expense of fabricating signs and the logistics of installing/replacing Braille and raised letter signs would be prohibitive to transit authorities. We suggest that the Access Board explore ways that could more practically address this issue, including new technologies.

    Some stops have up to 30 or more different vehicle routes stopping at one location. The proposed change, which would lower the mid-sign reach of 48 inches

    1103.3 Pedestrian Access Route Clear Width. The minimum clear width of a pedestrian access route shall be 48 inches

    Comment: It could be very impractical to provide a total clear width of 54", from face of curb to the back of the sidewalk, for the accessible route due to tight right-of-ways. Many sidewalks are about 42" wide with utility poles right in the middle. Some cities also have a 24" - 36" clear zone from the face of curb where no utility poles/trees/bus signs shall be installed. Adding the 24" utility-clear zone, plus the diameter of utility pole base (about 12"-18") to the 48" ADA clear width, the sidewalk width would be 84" wide. Any such sidewalk improvement would require acquiring property from adjacent owners, which will definitely increase project cost. Such a provision would discourage local jurisdictions from improving their sidewalks.

    This paragraph also may preclude a transit system from installing a bus sign on a sidewalk with less than 72" (6 ft) wide (24" clear zone from face of curb and 48" ADA clear zone). We are also concerned about the definition on accessibility clearances around the bus stop or information sign. If the 48" ruling applies around the entire sign, this poses another significant problem.

    1104.3.2 Detectable Warnings. Detectable warning surfaces complying with 1108 shall be provided, where a curb ramp, landing, or blended transition connects to a crosswalk.

    1108.1 General. Detectable warnings shall consist of a surface of truncated domes aligned in a square grid pattern and shall comply with 1108.

    1108.1.4 Size. Detectable warning surfaces shall extend 24 inches

    Comment: We recommend that truncated domes not be required at curb ramps, landings and blended transitions. In our view, truncated domes generally should only be used on transit platform edges. Truncated domes can set off muscle spasms for persons with spinal injuries in wheelchairs. Moreover, use of truncated domes in curb ramps, crosswalks, and blended transitions may cause persons with visual impairments to become confused as to where they are and could lead to serious injury. Currently, truncated domes are used at rail stations to indicate to persons with visual impairments to stop; in contrast, the guideline proposes to use truncated domes at curb ramps to indicate to a person with visual impairments to proceed. An alternative tactile tile must be used in this application. If the provision is not removed the minimum should be 36 inches

    1102.3 Alternate Circulation Path. An alternate circulation path complying with 1111 shall be provided whenever the existing pedestrian access route is blocked by construction, alteration, maintenance, or other temporary conditions.

    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.

    1111.4 Protection. The alternate circulation path shall comply with 307 and shall be protected with a barricade complying with 1111.6 to separate the pedestrian access route and alternate circulation path from any adjacent construction, drop-offs, openings, or other hazards.

    Comment: The requirement for the alternate circulation path to be parallel to the disrupted pedestrian access route and on the same side of the street is very often not possible due to the nature of constructions projects which are causing the disruption. In situations where entire rights-of-way are being built or redesigned there is often no safe area to establish a pedestrian access route which meets this guideline. We recommend that the proposed guideline be changed to read that the alternate circulation path shall be located in the safest and most direct route feasible within the scope of the construction project.

    Conclusion

    We appreciate the opportunity to comment on this proposal and look forward to an NPRM that accommodates the comments of all affected parties. For further information, please contact Kristin O'Grady at [... ].

    SUBJECT: Comments and Recommendations on the Draft Guidelines for Accessible Public Rights-of- Way submitted by the Kansas Department of Transportation.

    Please accept this letter as the comments and recommendations of the Kansas Department of Transportation (KDOT) on the Draft Guidelines for Accessible Public Rights-of- Way. KDOT had in-house experts, in the fields of traffic engineering, design, construction, maintenance and legal review the draft guidelines. The attached comments are not based upon speculation or conjecture, but are real problems that will need to be addressed at some point.

    KDOT personnel also had the opportunity to participate in the comments and recommendations submitted by the American Association of State Highway and Transportation Officials and would like the Access Board to consider the comments in that document as being incorporated into this letter.

    Overall issues and concerns:

    Maintenance issues:

    The scoping requirements make it clear that the accessibility guidelines apply to new construction, alterations, and additions. However, it can be implied that the affected areas will have to be maintained to the guidelines. The cost and time associated with inspecting facilities to make sure they comply with the guidelines would seriously deplete governmental resources.

    In addition, the guidelines could be used as a new standard by which right of way facilities need

    to be maintained for all persons, not just the disabled. For instance, changes in elevation in a

    pedestrian path must not be greater than Y4 inch

    level that is 3/8 of an inch will the responsible governmental entity be held liable. In most jurisdictions, governmental entities are held to maintaining right of way in a condition reasonably safe for its intended purpose. If the proposed guidelines are construed as creating a new standard for maintenance, governmental entities will payout more settlements and judgments. In addition, the cost of maintenance would most likely be a budget breaker.

    Cost implications:

    When the ADA was enacted, proponents cited numerous examples where complying with the ADA requirements in new construction did not cost much more than not complying with the requirements. However, that doesn't appear to be the case with the Accessibility Guidelines for Public Rights-of-Way. The cost of installing elevators at overpasses is estimated to almost double the cost of an overpass. The cost of complying with the requirements for alternate circulation paths could add ten fold or more to the cost of conducting a short term maintenance operation on a sidewalk. Governmental entities are cutting back in most areas in an attempt to accommodate ever shrinking budgets. The guidelines as currently written would be a huge cost item competing with essential services in governmental budgets.

    Conflicts with other standards:

    The Proposed Guidelines for Accessible Public Rights-of-Way do not appear to consider the fact that many of the provisions contained in the Guidelines conflict with existing standards and regulations. Like many governmental entities, KDOT is legally required to follow the Manual on Uniform Traffic Control Devices (MUTCD). The Proposed Guidelines for Accessible Public Rights of Way require traffic control in locations where it may not be warranted by the MUTCD. Additionally, KDOT follows the American Association of State Highway and Traffic Officials (AASHTO) A Policy on Geometric Design of Streets and Highways (Green Book) for criteria in designing roadways. Following the proposed guidelines will interfere with meeting the criteria set out in the Green Book. For instance, meeting the cross slope requirement at cross walks on streets with vertical curves could affect the design speed of the roadway. Complying with the proposed guidelines could also affect numerous other federally mandated requirements regarding air quality, environmental issues, and historic preservation.

    1101.3 Defined Terms:

    Pedestrian Access Route: KDOT recommends that the definition of "Pedestrian Access Route" be changed to "An accessible corridor intended for pedestrian use within the public right-of - way." KDOT has defended numerous claims brought by pedestrians who were hurt when using a location that wasn't intended for pedestrian use, i.e. a pedestrian on an Interstate highway; a sledder on Interstate right-of-way; and a pedestrian on a controlled access facility. Without the word "intended" being included in the definition there would be arguments that paved shoulders, county roads, grassy medians, etc. need to comply with the provisions for a pedestrian access route.

    1102 Scoping Requirements:

    1102.2.2 Alterations (of existing Public rights-of-way]: It is KDOT's recommendation that provision governing "Alterations" specifically state that maintenance work does not trigger the need for accessibility improvements.

    Additionally, KDOT recommends that a percentage limit be put on the amount spent making an "alteration" accessible. A requirement that alterations trigger the need to make accessibility improvements without any dollar limit to be spent on the accessibility improvement could cause governmental entities to not do planned alterations. Of course, if an alteration is not done because of the cost associated with making the accessibility improvements it leaves disabled and non-disabled people alike without upgrades to their pedestrian access system.

    The scoping provision on alterations also provides that alterations do not have to be in compliance with the requirements if compliance is "technically infeasible". More often than not an alteration in compliance with the standards will be technically feasible, but will not be reasonable because of the amount of right of way required, the cost of making the alteration, the destruction of historic elements, and the conflicts between the accessibility guidelines and engineering standards. KDOT would request that alterations be in reasonable compliance with the accessibility guidelines.

    1102.3 Alternate Circulation Path: This section requires that an alternate circulation path be provided whenever a pedestrian access route is blocked by construction, alteration, maintenance, or other temporary conditions. KDOT recommends that the words "other temporary conditions" be removed from the requirement. "Other temporary conditions" is far too general to give the proposed guideline any sense of reasonableness. A temporary condition could be when a van with a lift is unloading passengers onto the sidewalk, there is snow or ice on the sidewalk, or a family is moving and has boxes stacked on the sidewalk. Therefore, KDOT recommends the removal of the words "other temporary conditions" from the requirement in 1102.3.

    1102.8 Pedestrian Crossings: This section requires that pedestrian crossings comply with the provisions of 1105. 1105 appears to apply to locations where pedestrians cross streets. In the State of Kansas the only location where it is illegal for a pedestrian to cross a street is between two signal controlled intersections and crossing those facilities where pedestrians are prohibited. Therefore, the guideline could be read as requiring all locations on Kansas streets that are not between two signal controlled intersections or on pedestrian prohibited facilities as having to comply with the provisions of 1105. KDOT recommends that the section be rewritten to apply only to marked crosswalks including any medians, pedestrian overpasses and underpasses; and any stairs or escalators.

    1103 Pedestrian Access Route

    1103.3 Clear Width [of Pedestrian access routes]: This section requires the minimum clear width of a pedestrian access route to be 48 inches

    1104 Curb Ramps and Blended Transitions:

    1104.3.4 Grade Breaks [at curb ramps and blended transitions]: This section provides that grade breaks shall not be permitted on curb ramps, blended transitions, landings, and gutter areas. KDOT recommends that an exception be written in that makes it clear that water drainage areas with grade breaks between the road cross slope and the back of the curb be allowed. There is no way to avoid a grade break in this area and still carry runoff down the street.

    1105 Pedestrian Crossings:

    1105.2.1 Width [of a crosswalk]: This section provides that crosswalks shall be a minimum of 96 inches

    1105.2.2 Cross Slope [of a crosswalk]: The proposed guidelines require that the cross slope on crosswalks be 1:48

    Second, the primary purpose of the streets is to accommodate vehicular traffic. Flattening the crosswalks in areas of hilly terrain could cause control and safety problems for vehicular traffic. This is even more of a concern for emergency vehicles. If a vehicle loses control in an intersection it is the pedestrians who are not protected and in the way of an errant vehicle.

    Finally, the cost of constructing the flattened crosswalk and then making the necessary adjustments to the street, the sidewalks, utilities, and drainage would be cost prohibitive. In addition, there is the cost associated with the damaging effect on vehicles traveling through the flattened area and the costs: property, medical, time off work, and legal, surrounding foreseeable accidents in the intersection.

    KDOT recommends that the guidelines require a crosswalk to be constructed with the minimum cross slope achievable while staying within generally accepted and prevailing highway design criteria.

    1105.3 Pedestrian Signal Phase Timing: This section requires that pedestrian signal phase timing be calculated at 3.0 feet

    1105.5.3 Approach [of pedestrian overpasses and underpasses]: The proposed guidelines mandate that elevators be installed where the rise to a pedestrian overpass exceeds 60 inches

    1105.6.1 Separation [at roundabouts]: The accessibility guidelines provide that barriers be provided along the street side of the sidewalk where pedestrian crossing is prohibited at a roundabout. No other guidance is provided about what type of barrier should be used at such a location. A barrier used in this type of situation will need to be crashworthy, have tested end treatments, and not be a restriction for sight distance of the motorists. Even if such a barrier could be designed and manufactured, a barrier complying with the requirements on crashworthiness and not impairing sight distance will add substantially to the cost of constructing a roundabout. KDOT recommends this provision be dropped.

    1105.6.2 Signals [at roundabouts]: This section mandates the installation of pedestrian signal devices at crosswalks on a roundabout. KDOT has serious misgivings about this requirement. Stop control signals on roundabouts defeats the purpose of roundabouts. Roundabouts keep traffic moving at a reduced speed. This in turn increases traffic capacity, reduces the severity of crashes, and reduces harmful emissions. A requirement for the installation of pedestrian signals at crosswalks in roundabouts will seriously reduce the number of roundabouts constructed. In addition, a stop control on a roundabout is unexpected by drivers. Unexpected conditions increase the likelihood of vehicle crashes injuring vehicle occupants as well as pedestrians. Finally, the proposed guidelines' mandatory provision totally ignores whether the MUTCD warrants the installation of a pedestrian signal at the crosswalk or not. KDOT recommends that this provision be removed. In the alternative, KDOT recommends that the provision be reserved until the Transportation Research Board's National Cooperative Highway Research Program Project 3-65, Applying Roundabouts in the Untied States is complete. The research project can be used as a basis for writing appropriate accessibility provisions for roundabouts.

    1105.7 Turn Lanes at Intersection: This provision mimics the provision concerning pedestrian signals at roundabouts. Consequently, KDOT shares the same concerns with this provision as it does on the provision governing signals at roundabouts.

    1106 Accessible Pedestrian Signal Systems: The provisions governing accessible pedestrian signal systems cover items such as audible and vibrotactile indications of the walk interval; the location of the signals; the minimum distance from other signals, (which prohibits the use of two signal heads on the same support); locator tones on the pedestrian push button; and directional and information signs that must provide information in both tactile and visual forms. KDOT's concern is the cost associated with the design, construction and maintenance of such elaborate pedestrian signals. KDOT recommends that the Access Board wait for information obtained in the National Cooperative Highway Research Program Project 3-62, Guidelines for Accessible Pedestrian Signals before setting regulations in this area.

    1108 Detectable Warning Surfaces: KDOT recommends that the Access Board exclude the requirement for truncated domes on curb cuts with a slope of I: 15 or steeper. There have always been concerns over the use of truncated domes. It is known that truncated domes are difficult to maintain in winter weather, and that they cause hardships for mobility impaired persons. Allowing a curb cut that is steep enough to be noticeable to the visually impaired, not a difficult maneuver for those with mobility impairments, and is not a maintenance problem for governmental entities benefits all concerned parties.

    1111 Alternate Circulation Path: This series of provisions set out the requirements for routes to be used when a pedestrian access route is closed. KDOT has serious concerns with the provisions for alternate circulation paths. A major concern of KDOT's is that no time period for the construction or maintenance activity that closes the pedestrian access route be required before triggering the requirement for an alternate circulation path. On projects that do not last more than one day the cost associated with designing an alternate path, bringing in the barrier and setting it up, signing the alternate path and then taking the alternate path down when the activity is over would significantly increase the time and cost involved in doing any type of work that requires closure of a pedestrian access route.

    1111.3 Location [of alternate circulation paths]: This provision requires the alternate circulation path to be on the same side of the street as the disrupted one. In many cases this would be extremely expensive or cause a safety concern. To place the alternate circulation path on the same side of the street would require that easements be acquired and private property torn up to build a temporary walkway, or that the street be used as the pedestrian route and vehicular traffic be detoured. The first choice results in a use of taxpayer dollars that would not be supported by the public and the second results in a safety issue for both pedestrians and drivers. Furthermore, attempting to accommodate both construction traffic and the alternate circulation path would be difficult if not dangerous to pedestrians.

    1111.4 Protection [of the alternate circulation path] and 111.6 Barricades [to provide protection to the alternate circulation path]: These two provisions require that barricades be placed around an alternate circulation path. KDOT's first concern is that it appears the Access Board wants to require barricades to protect pedestrians. Barricades do not provide protection. Barricades provide delineation. A barrier provides protection. However, KDOT also has concerns over using barriers around alternate circulation paths. Before a barrier is used it must be determined if the barrier, which is an obstacle to vehicular traffic, will prevent more injuries than it will cause if hit. Installation of a barrier may be acceptable at locations with high vehicle traffic and high pedestrian traffic, but at many locations a barrier would not be warranted. In addition, the barrier would have to be crash worthy in case an errant vehicle ran into it. KDOT is unaware of any product approved for this type of situation.

    KDOT recommends that the requirements for alternate circulation paths follow the provisions of the MUTCD. As written the proposed guidelines are too costly, dangerous to both pedestrians and drivers, increase the time length for small jobs on the pedestrian access route, and could be impossible to apply in a reasonable manner during some types of operations.

    Conclusion:

    The Kansas Department of Transportation has serious concerns about the proposed guidelines. Implementing the guidelines as currently written will significantly increase construction and maintenance cost. Many provisions in the guidelines conflict with accepted practices and established guidelines for highway and street design and, if followed, could easily increase the risk of accident for both drivers and pedestrians. Numerous provisions in the guidelines create mandatory traffic control where it is not warranted under existing standards. The guidelines require engineers to choose between following the guidelines and using engineering judgment in deciding upon an appropriate and safe design.

    The Kansas Department of Transportation would like to thank the Access Board for considering KDOT's comments and recommendations.
