NOTES: Data are for the 50 states and the District of Columbia. The terms poor and mediocre as used here are Federal Highway Administration (FHWA) pavement condition criteria term categories for quantitative International Roughness Index and Present Serviceability Ratings. (See, http://www.fhwa.dot.gov/policy/2002cpr/ch3b.htm, Exhibit 3.3 for further detailed information.) Because of the transition to a new indicator for pavement condition beginning with FHWA data published in 1993, comparisons between pre-1993 data and 1993 and later data are inappropriate.
