This project was part of a larger effort of the RERC-APT to research and develop methods to empower consumers and service providers in the design and evaluation of accessible transportation equipment, information services and physical environments. Data collected in this project was used to design and evaluate vehicle features, boarding technologies and design of stops and stations. Research on the anthropometry of wheeled mobility devices and their users indicated that current dimensions prescribed in US accessibility standards for transportation are inadequate, e.g. clear floor area and ramp slope. The researchers included these findings when they submitted comments in response to the Access Board’s proposal to revise and update its accessibility guidelines for buses, over-the-road buses and vans. Findings from the research were also used to provide the Niagara Frontier Transportation Authority (NFTA) with recommendations for new bus designs; two of these recommendations were incorporated in two new buses.
