- Abstract
- National Highway Planning Network Points is a point theme representing nodes in the major highway system of the United States. 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.
- Supplemental Information
- The NHPN version 2005.08 contains 8 polyline features (RECIDs 4000057, 4000855, 41000287, 41002220, 48000952, 72001074, 72001170, and 72001488) that are each defined by more than 500 shape points. These features will not import correctly into the workstation version of ArcInfo, which has a 500 shapepoint limit. When importing into the workstation version of ArcInfo, the 8 features will be automatically split into 2 features each. As part of this process, attributes are simply duplicated on the split features. Because of this, additional nodes are added. The additional nodes will have incomplete attribution.

- Data Quality Information
- Attribute Accuracy Report
- RITA/BTS quality checks were to cross reference the dataset with the state dataset to determine if the spatial data and attribute data were accurate within each state. Further QA/QC revealed that the NHPN version 2005.08 contains 8 polyline features (RECIDs 4000057, 4000855, 41000287, 41002220, 48000952, 72001074, 72001170, and 72001488) that are each defined by more than 500 shape points. These features will not import correctly into the workstation version of ArcInfo, which has a 500 shapepoint limit. When importing into the workstation version of ArcInfo, the 8 features will be automatically split into 2 features each. As part of this process, attributes are simply duplicated on the split features. Because of this, additional nodes are added. The additional nodes will have incomplete attribution.
- 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. Further QA/QC revealed that the NHPN version 2005.08 contains 8 polyline features (RECIDs 4000057, 4000855, 41000287, 41002220, 48000952, 72001074, 72001170, and 72001488) that are each defined by more than 500 shape points. These features will not import correctly into the workstation version of ArcInfo, which has a 500 shapepoint limit. When importing into the workstation version of ArcInfo, the 8 features will be automatically split into 2 features each. As part of this process, attributes are simply duplicated on the split features. Because of this, additional nodes are added. The additional nodes will have incomplete attribution.
- 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 2002, NHS system and intermodal connectors aw 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 2004 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.
