642.3 Americans with Disabilities Act of 1990
The Americans with Disabilities Act of 1990 (ADA) is legislation which prohibits discrimination on the basis of disability. Other Federal laws which affect the design, construction, alteration, and operation of facilities include the Architectural Barriers Act of 1968 (ABA), and the Rehabilitation Act of 1973. These laws apply to all federally funded facilities. The ADA applies to facilities, both public (Title II) and private (Title III), which are not federally funded. Newly constructed and altered facilities covered by Titles II and III of the ADA must be readily accessible to and usable by people with disabilities.
The Department of Justice (DOJ) has rulemaking authority and enforcement responsibility for Title II, while USDOT is legally obligated to implement compliance procedures relating to transportation, including those for highways, streets, and traffic management. The FHWA Office of Civil Rights oversees the DOT requirements in these areas.
The guidelines provided in MoDOT standards are based upon the federal requirements contained in the 2010 ADA Standards for Accessible Design, based on ADAAG. Exceptions will be where the federal standards do not provide specific ADA accessibility aspects/requirements. In those cases, guidelines and best practices will be used based on the proposed Public Rights-of-Way Accessibility Guide (PROWAG) or other available FHWA guidelines. Where applicable, best practice references will be specifically cited in the guidelines.
The Manual on Uniform Traffic Control Devices has been developed with the cooperation of the Access Board and can be considered the standard for traffic control regulations. Part 4, Chapter 4E specifically addresses traffic signals and Part 6, Chapter 6D addresses work zones. Other sections include pedestrian considerations as needed.
