Passed by Congress in 1990, this civil rights legislation mandates equal opportunities for person with disabilities in the areas of employment, transportation, communications and public accommodations. ADA mandates that persons with disabilities cannot be denied access to public transportation facilities and services, and that those services must be comparable to those provided to the general public. ADA provisions require that all newly acquired and modified vehicles operated by public and private transportation providers be accessible, and mandate that public transit agencies provide ADA paratransit services that complement their fixed-route services for people who cannot used those fixed-route services. ADA paratransit services must be comparable in terms of response times, fares, geographic service area, and hours/days of service. They may not restrict the number of trips an individual can make or prioritize service based on the rider's trip purpose. Under this Act, transit providers must assure system-wide accessibility of their demand-responsive services to persons with disabilities. The regulations require only curb-to-curb service, but the grantee may provide a higher level of service.
