KEY: N = data do not exist.
NOTE: In 2000, the Federal Highway Administration began reporting road
condition for urban minor arterials and urban collectors using the
International Roughness Index, if available.
In prior years, data were only available using the Present
Serviceability Rating.
NOTE FOR DATA ON THIS PAGE: Road condition is based on measured
pavement roughness using the International Roughness Index (IRI). IRI is a
measure of surface condition. A comprehensive measure of pavement condition would require data on other
pavement distresses such as rutting, cracking, and faulting.
SOURCE FOR DATA ON THIS PAGE: U.S. Department of Transportation, Federal Highway Administration,
Highway Statistics, Washington, DC: annual editions, tables HM-63 and HM-64, available at
http://www.fhwa.dot.gov/ as of Feb. 1, 2002.
