TRB’s Transit Cooperative Research Program (TCRP) Report 119: Improving ADA Complementary Paratransit Demand Estimation examines tools and methods designed to predict demand for complementary paratransit service by public transit agencies that comply with legal requirements for level of service as specified by the Americans with Disabilities Act of 1990 (ADA) and implementing regulations. The ADA created a requirement for complementary paratransit service for all public transit agencies that provide fixed-route service. Complementary paratransit service is intended to complement the fixed-route service and serve individuals who, because of their disabilities, are unable to use the fixed-route transit system.
