a These data are derived from the Transit Economic Requirements
Model (TERM). TERM uses statistically determined decay curves to simulate the
deterioration of the Nation's transit vehicles, facilities, and other
infrastructure components. National
Transit Database (NTD) data are applied to these decay curves to estimate
conditions. Only the condition of
directly operated facilities are provided for 1995, 1997 and 2000. The NTD began gathering information on
facilities owned by bus systems providing services under contract in 1999
(known as purchased transportation), however, TERM did not base condition
estimates on this full set of facilities until 2002.
