2018 HPMS Public Release

Dataset Description

Provides the Full Extent attributes for HPMS ARNOLD.

The files have been compressed utilizing the zip file format and are organized by State reflecting highways that are part of the HPMS-defined Federal-Aid System:

  • 1 Interstate
  • 2 Principal Arterial – Other Freeways and Expressways
  • 3 Principal Arterial – Other
  • 4 Minor Arterial
  • 5 Major Collector
  • 6 Urban Minor Collector
  • Additionally, any other highways that are designated as part of the National Highway System

The following considerations should be adhered to:

  • ARNOLD will be used as the base.
  • The LRS will be maintained on all of the geometry.
  • Attributtes will be attached through Dynamic Segmentation which will have moderate recalculation of the Begin and End Points.
  • The geodetic accuracy and topological structure of the linework have not been evaluated. Use of these data for navigation is not recommended. The user assumes the risk.
  • National summaries created by aggregating this data may render different results from the information presented in FHWA's Highway Statistics tables. Although the same data was used to produce both formats, GIS processing that linked route data to attribute data may not have been successful and have impacted results in some areas. Data in this spatial format may not completely cover all Federal-aid highways. The information portrayed in the Highway Statistics tables represent the official calculations for national Extent, Condition and performance data and are compiled by enterprise database methodologies.
  • This information represented in these Data is a compilation of data collected from many State Departments of Transportation (DOT's). The FHWA extensively reviews the data for consistency and accuracy prior to publication. There may be some remaining discrepancies at the section level. Ultimately, the source of this data is the State DOT's. Subsequent errors that are detected will be passed back to the State DOT for investigation and if confirmed, will be corrected in the following HPMS cycle.

The HPMS Public Release has the following schema:
