"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.  ",,,,,,
