General Information
The International Roughness Index (IRI) defines roughness of pavements in a way that correlates to the movement of a simulated vehicle moving at ~50 mph. Bumps and dips in the pavement which would be experienced by the vehicle driver or rider would increase the IRI. Roughness smaller than a tire footprint that cannot be felt in a vehicle, such as small cracks, should not affect IRI values.

The Average Roughness Rating is based on the Average IRI broken down as such:
Good - IRI less than 95
Fair - IRI between 95 and 170
Poor - IRI greater than 170

All Interstates and state routes on the National Highway System (NHS) are collected in both directions annually. State routes not on the NHS are collected in one direction every other year.

This data is for the 2 year cycle of 2021-2022.
