alterations. These issues have been addressed in this second draft. Changes include the following: • referenced Manual on Uniform Traffic Control Devices (MUTCD) for crosswalk width; • reduced scoping in on -street parking to be consistent with parking lots; • set walking speed at 3.5 fps (consistent with new recommendations currently under consideration by the National Committee on Uniform Traffic Control Devices); • eliminated the provision requiring elevators to provide pedestrian access at overpasses and underpasses (either ramps, lifts, or elevators may be used); • modified scoping and technical provisions for alternate circulation routes to be consistent with current MUTCD requirements and alterations requirements, which would permit opposite side routes if same -side routes are not feasible; • provided relief (up to 5%) for maximum cross slope limits in pedestrian crosswalks at midblock and through -street locations where the roadway slope will necessarily exceed 2%; • clarified the placement of detectable warnings on curb ramps, landings, and blended transitions; • clarified the scoping in new construction and alterations of accessible pedestrian signals (APS); • limited pedestrian signalization at roundabouts and channelized turn lanes to pedestrian crossings (to the splitter) of two lanes of traffic or more; and • clarified the scope of alterations to include only that work included in the limits, boundaries, or scope of a planned project; clarified that there is no obligation in the guidelines to expand the scope or limits of a project to include other or adjacent work. Other changes included the addition of significant advisory material throughout the document. Advisory notes are for informational purposes only. The Board also considered industry recommendations that the guidelines be re -formatted to use transportation metrics and language and to be better coordinated with industry standards and documents, particularly the Manual on Uniform Traffic Control Devices (MUTCD). This draft is now formatted as a stand-alone document that expresses its dimensioning requirements first in international units, as is done in other industry documents. Its provisions have been harmonized with current MUTCD standards, support, options, and guidance. Industry terms and phrases have been adopted, and industry practices recognized where feasible. The Board is placing the revised draft in the docket to facilitate the gathering of cost data necessary for the next step in this rulemaking which is the preparation of a regulatory assessment for government review and approval prior to issuing a Notice of Proposed Rulemaking (NPRM). In order to develop an accurate picture of the potential costs and benefits of this rulemaking, the Board must work closely with the transportation industry representatives who have data on both current cost and industry practices and the knowledge and skills to assess potential effects. The Board is not seeking comments on this draft. Readers will have an opportunity to provide input when the NPRM is published. Additional figures will be included in the NPRM. 4
