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.
