Highway agencies use IRI thresholds to characterize road condition; for example, in the United States, an IRI of less than 95 in/mi (1.50 m/km) is generally considered by the Federal Highway Administration to be in "good" condition, an IRI from 96 to 170 in/mi (1.51 to 2.68 m/km) is considered "acceptable", and an IRI exceeding 170 in/mile (2. ...
