Abstract
The National Highway Planning Network 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.
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 modeling. The NHPN is the digital source used for coding and publishing the FHWA approved National Highway System maps.

Data Quality Information
Attribute Accuracy Report
RITA/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.
Logical Consistency Report
Topological relationships of node and link and uniqueness of entity IDs are verified by the computer algorithm developed under ArcGIS 9.1 environment.
Completeness Report
The complete urban principal arterial system and arterials in rural areas as reported to FHWA by December 1992 are inventoried in the database. Functional classification as reported in HPMS 2007, NHS system and intermodal connectors are reported to the FHWA by 2003. SIGN1, LNAME, route designation, route direction and route milepost as reported in HPMS 2002 are updated. Functional classes below arterial vary on a state-by-state basis. Any addition and modification to the National Highway System as reported to the FHWA by February 2010 is also included.
Horizontal Positional Accuracy Report
The original elements of the NHPN have been conflated to the 1:100,000 DLG-3 data set, which maintains a nominal accuracy of at least ±80 meters. Where new roads have been added which are not in the DLG-3 database, link alignments have been digitized or converted from digital sources acquired from state DOTs with a map scale of at least 1:100,000. Where State data source was not available, CENSUS TIGER/Line 2000 was used.
