NOTE: Numbers may not add to 100 due to rounding.
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.

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