This data product includes the national transportation performance measure infrastructure conditions, specifically the Good, Fair, & Poor condition ratings. These condition ratings, depending on surface type, are based on roughness, cracking, rutting & faulting.<br /></div><div style="font-family:"Avenir Next W01", "Avenir Next W00", "Avenir Next", Avenir, "Helvetica Neue", sans-serif; font-size:16px;"><br /></div><div style="font-family:"Avenir Next W01", "Avenir Next W00", "Avenir Next", Avenir, "Helvetica Neue", sans-serif; font-size:16px;">MDOT SHA Pavement Condition NHS data is owned & maintained by the MDOT SHA Office of Materials Technology (OMT). This data product is consistently updated on an annual basis for the prior year. This data product is for the year 2021. Though this data product as a whole is owned & maintained by MDOT SHA, the pavement conditions along roadways maintained by other Federal, State, County, and local government agencies are included within this data product. Roadway maintenance responsibility information can be further understood through the attribute values related to each linear segment.<br /></div><div style="font-family:"Avenir Next W01", "Avenir Next W00", "Avenir Next", Avenir, "Helvetica Neue", sans-serif; font-size:16px;"><br /></div><div style="font-family:"Avenir Next W01", "Avenir Next W00", "Avenir Next", Avenir, "Helvetica Neue", sans-serif; font-size:16px;"><div style="font-family:inherit;">MDOT SHA Pavement Condition (NHS) data includes performance measures for pavements that are based on three condition ratings of <b>Good</b>, <b>Fair</b>, & <b>Poor </b>calculated for each pavement section, as described in Detailed in “National Performance Management Measures for Assessing Pavement Condition,” 23 CFR 490 Subpart C (Code of Federal Regulations). </div><div style="font-family:inherit;"><br /></div></div><div style="font-family:"Avenir Next W01", "Avenir Next W00", "Avenir Next", Avenir, "Helvetica Neue", sans-serif; font-size:16px;">The included <b>Condition Ratings </b>are determined or calculated as follows:<br /></div><div style="font-family:"Avenir Next W01", "Avenir Next W00", "Avenir Next", Avenir, "Helvetica Neue", sans-serif; font-size:16px;"><br /></div><div style="font-family:"Avenir Next W01", "Avenir Next W00", "Avenir Next", Avenir, "Helvetica Neue", sans-serif; font-size:16px;"><b>International Roughness Index (IRI) Condition Rating</b> shall be determined / calculated for all pavement types using the following criteria.
