KEY: N = data do not exist; - = value too small to report.
a Historical differences in miles not reported result from the
transition from the Present Serviceability Rating (PSR) to the International
Roughness Indicator (IRI).
b Included in row below.
NOTES
Because of the transition to a new indicator for pavement
condition beginning with U.S. Department of Transportation, Federal Highway
Administration (FHWA) data published in 1993, comparisons between pre-1993
data and 1993 and later data are difficult. Thus, trend comparisons should be
made with care. For additional information, the reader is referred to the
accuracy profile for this table in the appendix. Total mileage in this table
will not match that in table 1-5 because of a change in the method of creating
mileage-based tables derived from the Highway Performance Monitoring System,
beginning with the 1997 issue of FHWA's Highway Statistics.
Data are for the 50 states and the District of Columbia.
Numbers may not add to totals due to rounding.
