DESCRIPTION
Abstract: 2022 RatingsWisDOT, 7/2023International Roughness Index (IRI) PM2If the record doesn’t have an IRI date (IRI_DT), then it was not measured by WisDOT. There are ‘0’ values in the pavement data for these but they are not measured values.OBJECTIDObject ID is a unique, not null integer field used to uniquely identify rows in GIS attribute tablesOVLP_IDOverlap ID is a non-business, unique, system assigned value used as a primary identifier.YR_RECYear Record is the calendar year to which a record applies.RDWY_LINK_IDRoadway Link ID uniquely identifies a specific segment of a roadwayBGN_OSET_MLSBegin Offset Miles is a linear reference for the beginning of a roadway segment measuring the distance in miles from the beginning of the Roadway Link IDEND_OSET_MLSEnd Offset Miles is a linear reference for the end of a roadway segment measuring the distance in miles from the beginning of the Roadway Link IDON_RTNMOn Route Name is the familiar, non-numeric designation for a route that the link resides on.FNCT_SYSFunctional System is the FHWA approved Functional System. 1 - Interstate, 2 - Freeway/Expressway, 3 - Principal Arterial Other, 4 - Minor Arterial, 5 - Major Collector, 6 - Minor Collector, 7 - LocalFAC_TYFacility Type is the operational characteristic of the roadway. 1 - One-Way Roadway, 2 - Two-Way Roadway, 4 - Ramp, 5 - Non-Mainline, 6 - Non-Inventory Direction, 7 - Planned/unbuiltNHSNational Highway System is the NHS status of the section. 1 - Non Connector NHS, 2 - Major Airport, 3 - Major Port Facility, 4 - Major Amtrak Station, 5 - Major Rail/Truck Terminal, 6 - Major Inner City Bus Terminal, 7 - Major Public Transportation or Multi-Modal Passenger Terminal, 8 - Major Pipeline Terminal, 9 - Major Ferry TerminalRTNMRoute Number is numeric designation assigned to Interstate, U.S., and State, highwaysSTRC_TYStructure Type is an indictor of if a roadway section is entirely on a bridge, tunnel, or causeway. 1 - Bridge, 2 - Tunnel, 3 - CausewaySURF_TYSurface Type is the surface type of the section. 1 - Unpaved, 2 - Bituminous Asphalt, 3 - Jointed Plain Concrete Pavement (including whitetopping), 4 - Jointed Reinforced Concrete Pavement (including whitetopping), 5 - Continuously Reinforced Concrete Pavement (CRCP), 6 - Asphalt-Concrete (AC) Overlap over Existing AC Pavement, 7 - AC Overlay over Existing Jointed Concrete, 8 - AC (Bituminous Overlay over Existing CRCP), 9 - Unbonded Jointed Concrete Overlay on PCC Pavement, 10 - PCC Overlap on PCC Pavement, 11 - Other (e.g. plank, brick, cobblestone, etc.) THRU_LNESThrough Lanes is the number of lanes of the entire facility in a given direction of travel.URB_CDUrban Code is the U.S.Census urban area code.FATG_CRKGCracking Percent is the percent of cracking on asphalt, concrete, or continually reinforced concrete, as it is detailed in the Highway Performance Monitoring System Field ManualFLTGThe average vertical displacement between adjacent jointed concrete panels measured in inches.IRIInternational Roughness Index measured in inches per mile.IRI_DTIRI date is the date the International Roughness Index was collected.RTNGAverage Rutting measured in inches.Shape_LengGIS assigned geometry linework measurement not for business useIRI_RatingInternational Roughness Index rating for segment in accordance with Transportation Performance Management guidanceRTNG_RatingRutting rating for segment in accordance with Transportation Performance Management guidanceFLTG_RatingFaulting rating for segment in accordance with Transportation Performance Management guidanceFATG_CRKG_RatingCracking Percent rating for segment in accordance with Transportation Performance Management guidanceSEG_RatingOverall segment rating in accordance with Transportation Performance Management guidance
