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.
