The nationwide fleet of lift- or ramp-equipped transit buses increased to 87 percent (58,785 buses) in 2001 from 52 percent of the bus fleet (29,088 buses) in 1993 (figure 48). While increased compliance with Americans with Disabilities Act (ADA) requirements (see box) occurred from 1993 to 2001, the rate of compliance has differed among bus types (figure 49). The large bus fleet had the highest level of compliance in 1993 and articulated buses the lowest. By 2001, the large bus fleet continued to have the highest rate (95 percent, or 40,501 vehicles), followed by medium buses with 94 percent (7,337 vehicles). Meanwhile, small buses had the lowest level of compliance (85 percent, or 9,176 vehicles). Articulated bus compliance fell in the middle at 89 percent, or 1,771 vehicles .
Rail transit infrastructure consists of trackand stations. In 2001, 50 percent (1,374) stations were ADA accessible, serving automated guideway transit, cable cars, commuter rail, heavy rail, inclined plane, light rail, monorail, and the Alaska Railroad. In 2001, light-rail riders enjoyed 76 percent accessibility (408 stations), followed by commuter-rail riders with 50 percent accessibility (583 stations) and heavy-rail riders with 35 percent accessibility (352 stations) .
