Footnotes

1/ Some States elect to report International Roughness Index (IRI) for these systems; some report IRI for some sections and PSR for some sections. Some differences from other tables may be noted because these are estimated from sample data.

2/ Data are reported as the IRI in inches per mile. Reference: World Bank Technical Paper Number 46, 1986. Lower IRI represents smoother riding roadways; to obtain a comprehensive assessment of pavement condition, additional measures of pavement distress are needed.

3/ The " Present Serviceability Rating " (PSR) is a subjective, primarily ride-based system adapted from the " AASHO ROAD TESTS " conducted in the late 1950’s and early 1960’s. Reference: Highway Special Report 61E, 1962. The PSR values range from 0.1 to 5.0; higher PSR values represent smoother riding roadways.

4/ Excludes 770 miles of Federal agency owned roads.

5/ 2004 data used.
