New pedestrian guidelines:New pedestrian guidelines:

The Access Board began work on public rights-of-way guidelines (PROWAG) to supplement ADAAG in 1992:

► section 14 (NPRM 2002/IFR 1994); ► sidewalk video and design manual (1997);► advisory committee (1999);► PROWAAC report (2001);► draft PROWAG NoA (June ‘02);► revised draft PROWAG NoA (November ’05)

PROWAG adapts ADAAG, but....PROWAG adapts ADAAG, but....

The PROWAG draft adapts ADAAG to the rights-of-way environment. The new guidelines will be a stand-alone document using rights-of-way industry measures and language.

Key differences: ► the slope limits of an accessible route are not

applied to sidewalks; ► there is no path-of-travel requirement, ► new communications features (DW, APS) are

required, and► metric units lead.

PROWAG PROWAG Key Provisions: A high degree of convenient access is easiest to achieve in new construction

NEW CONSTRUCTION: THE ‘CORN FIELD IN KANSAS’

PROWAGPROWAGKey Provisions: In alterations, you may not be able to optimize conditions for every user (follow new construction guidelines to the maximum extent feasible)

Next steps in rulemaking:Next steps in rulemaking:

We are currently working with key highway industry stakeholders to develop the data we need to analyze cost/benefit issues for the regulatory assessment:

► AASHTO ► APWA► FHWA► ITE► Tx DOT► TRB

Key cost issues identified:Key cost issues identified:

Highway industry stakeholders reviewed the draft guidelines and a 2001 industry cost study of the PROWAAC recommendations over the course of several meetings. By consensus, five cost items were identified as significant:

► detectable warnings (savings from reduced area) ► APS (integration may lower cost)► tabled intersections► temporary pedestrian routes► roundabout signalization

PROWAGPROWAGDetectable Warnings: All ramps and raised crossings must have detectable warnings to provide notice underfoot of the change from a pedestrian to a vehicular route.

DWs AT WHITE HOUSERETROFIT PORTLAND, OR

PROWAGPROWAGDetectable Warnings: Blended transitions have a slope of less than 5%. Detectable warnings are provided across the entire transition.

PROWAGPROWAGDetectable warnings are required at medians.

PROWAGPROWAGAccessible Pedestrian Signal (APS): When new pedestrian signals are installed, include APS. Audible signal is integrated in pedbutton.

PROWAGPROWAGAPS: Provide 30”x48” clear ground space at all controls within reach range.

10” AWAY

48” HIGH

APSAPS

• While we don’t know what is happening everywhere we do know…• The State of Maryland has a policy in

place to include APS in all new Ped signal installations

• FHWA encourage the use of the draft in absence of specific PROW standards

APSAPS

• The draft ties installation of APS to:• Providing pedestrian signals (in new

construction and alterations)• It is NOT a retrofit requirement and is

NOT tied to the marking of crosswalks.

• NCHRP 3-62 has helped the signals technical committee develop language for MUTCD which the Access Board will coordinate with for consistancy.

PROWAGPROWAGTabled Intersections: Where two directions of travel intersect at corners (or where a turn must be made), the PAR must be ‘level’ (2% in both directions) or ‘tabled’. (5% where intersection has no stop control)

THIS… ….NOT THIS!

PROWAGPROWAGTemporary PARs: When the PAR is detoured, provide an alternate route; same-side is best, if feasible (MUTCD)

PROWAGPROWAGTemporary PARs: The alternate circulation path needscurb ramps, too

PROWAGPROWAGRoundabouts: Provide pedestrian signals at roundabouts where pedestrian crossings are more than one lane.

TWO HEADS MAY BE BETTER THAN THREE (AND RARELY USED…)

Signalization of Signalization of RoundaboutsRoundabouts• Applies to multi-lane roundabouts• We currently do not know what

jurisdictions are doing.• The Access Board with FHWA are

trying to do some experimentation.• There is also a NCHRP project (3-78)

doing research.
