The 1990 Americans with Disabilities Act is impacting transit requirements. This law insists that new transit bus designs be easy to access for people with physical problems, including those who must travel in wheelchairs. Low floors are becoming mandatory. However, because of the need to get past the axles, these buses do not have true low floors, in that they do not extend the full length of the vehicle at one and the same low level. Matters are further hampered by budget constraints, rising fuel and maintenance costs, and axle-weight limitations. These trends are combining to render the conventional diesel-powered heavy-duty transit bus ever more untenable as time goes on. An alternative that is needed is the hybrid electric bus. Hybrid electric propulsion offers solutions to many of the problems associated with the mechanically driven diesel buses of today, and is expected to revolutionize the transit bus industry over the next decade.
