Figure 11-3 - Rural Roads in Poor or Mediocre Condition by Functional Class: 1993-2002

Excel | CSV | Table Version

NOTES: Data are for the 50 U.S. 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 U.S. Department of Transportation, FHWA data published in 1993, comparisons between pre-1993 data and 1993 and later data are inappropriate.
