Update:
Public Rights-of-Way Rulemaking
Scott Windley, PROW Team Leader

U.S. Access Board
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....
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.
Organization of the draft (2):
►
Preamble (discussion)
--explains decision making; highlights changes
--Q&A on alterations
►
Text
--R1: general
--R2: scoping requirements
--R3: PROW technical provisions
--R4: references to other (building) technical
provisions in ADA/ABA-AG

R1 Application and Administration
R2 Scoping Requirements
R3 Technical Provisions
--Pedestrian access route (PAR)
--Alternate circulation path
--Curb ramps and blended transitions
--Detectable warning surfaces
--Pedestrian crossings
--Accessible pedestrian signals (APS)
--Street furniture
--On-street parking
--Callboxes
R4 Supplementary Technical Provisions (from ADA/ABA-AG)
PROWAG
Key Provisions: A high degree of convenient access is
easiest to achieve in new construction
NEW CONSTRUCTION: THE
‘CORN FIELD IN KANSAS’
PROWAG
Key Provisions: In alterations, you may not be able to
optimize conditions for every user (follow new
construction guidelines to the maximum extent feasible)
ALTERATIONS
RESURFACING
RECONSTRUCTION
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:
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
PROWAG
Detectable Warnings: All ramps and raised crossings must
have detectable warnings to provide notice underfoot of
the change from a pedestrian to a vehicular route.
RETROFIT PORTLAND, OR
DWs AT WHITE HOUSE
PROWAG
Detectable Warnings: Blended transitions have a slope of
less than 5%. Detectable warnings are provided across the
entire transition.
PROWAG
Detectable warnings are required at medians.
PROWAG
Accessible Pedestrian Signal (APS): When new pedestrian
signals are installed, include APS. Audible signal is
integrated in pedbutton.
PROWAG
APS: Provide 30”x48” clear ground space at all controls
within reach range.
48” HIGH
10” AWAY
APS
• 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
APS
• 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.
PROWAG
Tabled 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!
PROWAG
Temporary PARs: When the PAR is detoured, provide an
alternate route; same-side is best, if feasible (MUTCD)
PROWAG
Temporary PARs: The alternate circulation path needs
curb ramps, too
PROWAG
Roundabouts: 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 Roundabouts
• 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.
