      <abstract>The NHPN is a Geographical Information System (GIS) database that contains line features representing over 450,000 miles of current and planned highways in the United States, including the National Highway System (NHS), the Strategic Highway Network (STRANET), and rural minor arterial. The current NHPN contains a set of data attributes that are suited to analytical modelling of large-scale transportation activities.</abstract>
      <purpose>The primary purpose of this geospatial data set is to serve the FHWA needs in highway planning, policy analysis, visualization of the Highway Performance Monitoring System (HPMS) database and network modelling.</purpose>

      <attraccr>OST-R/BTS quality checks were for cross referencing purposes . The dataset was cross-referenced with the state dataset to determine if the spatial data and attribute data were accurate within each state.</attraccr>

    <logic>The uniqueness of entity IDs and the values of begin and end milepost values were generated by the computer algorithm developed under ArcGIS 10.1 environment.</logic>
    <complete>All NHPN links with HPMS 2010 GIS network representation have been conflated to the NHPN. HPMS attributes State_Code, Year_Record, Route_ID, Begin_Point, End_Point, F_SYSTEM has been transferred. the Begin_Point, End_Point fields have been calibrated based on shape length and sequence when a link was split.</complete>
    <posacc>
      <horizpa>
        <horizpar>The original elements of the NHPN have been conflated to the HPMS 2010 GIS network, which requires spatial resolution of 1:100,000 or better. However, most of the state submitted data has spatial resolution between 1:5,000 to 1:10,000.</horizpar>
