Public Right-of-Way Access Advisory Board (PROWAAC)

From the PROWAAC Website:

“The Public Rights-of-Way Access Advisory Committee (PROWAAC) was established in October 1999 as the first step in developing additional ADAAG provisions and special application sections… Committee members represented the diverse interests of those affected by this rulemaking including persons with disabilities, federal, state, and local public works and transportation agencies, organizations representing design professionals, pedestrian and bicycle organizations, standard-setting organizations, and organizations representing the access needs of individuals with disabilities.”

“The committee began its work by reviewing available information related to providing access for persons with disabilities in public rights-of-way. The committee reviewed the section 14 document included in ADAAG under the Access Board's interim final rule issued in June 1994, the Board's Accessible Rights-of-Way Design Guide, the Federal Highway Administration's Designing Sidewalks and Trails for Access, and other similar information. They also examined and discussed approaches used by states and local governments to meet access responsibilities in the absence of specific ADAAG guidance, and discussed pending design documents such as the American Association of State Highway and Transportation Officials' (AASHTO) Pedestrian Design Guide.”

Basic Principles

Continued from the PROWAAC Website:

PROWAAC's basic principles for accessibility standards for the public should:

  • Provide for equal opportunity
  • Maximize accessibility for all users
  • Be reasonable
  • Be clear, simple and understandable
  • Be enforceable and measurable
  • Be constructible and maintainable within today's technological capabilities
  • Address safety for both pedestrians and motor vehicle operators
  • Provide guidance for implementing agencies and the public
  • Be flexible enough to include future technologies
  • Be consistent with ADAAG
  • Support independent use by persons with disabilities

“The advisory committee explored many approaches and compromised in many areas to reach agreement on recommended accessibility standards for new and altered public rights-of-way covered by the ADA. The standards proposed by the committee and presented in this report include consideration of the latest available information and design and construction practices.”
