National Transportation Atlas Database
The National Highway Planning Network (NHPN) dataset was compiled on May 01, 2014 from the Federal Highway Administration (FHWA) and is part of the U.S. Department of Transportation (USDOT)/Bureau of Transportation Statistics (BTS) National Transportation Atlas Database (NTAD). This dataset is a comprehensive network database of the nation's major highway system. It consists of the nation's highways comprised of Rural Arterials, Urban Principal Arterials and all National Highway System routes. The data set covers the 48 contiguous States plus the District of Columbia, Alaska, Hawaii, and Puerto Rico. The nominal scale of the data set is 1:100,000 with a maximal positional error of 80 meters.
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.

Data set is considered complete for the information presented, as described in the abstract. Users are advised to read the rest of the metadata record carefully for additional details.
The National Highway Planning Network was created by building the Node-Link Geometry for conflation. Steps include splitting line at intersection using ArcGIS planarize tool, creating node point features for the intersections, removing uncommon points in overpass/underpass. Conflation of NHPN is based on HPMS. Attribute is then conflated. Dual carriage treatments covert dual carriage from HPMS to a centerline. Simplify features using custom built ArcGIS tool. Mile marker calibration and line direction fix using custom built ArcGIS tool that takes into account the connectivity of adjacent links and the shape lengths. Dangling errors fix for overshoot and undershoot errors. Connectivity errors fix for overshoot and undershoot errors. Edge matching to connect interstates and other appropriate links from adjacent states. Topology validations to remove overlap errors. Record ID assignments using computer program to ensure unique ID assignment and to keep a connection to previous version of NHPN.
