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.

Highway Administration, Highway Statistics, Washington, DC: annual editions,
