Highway Performance Monitoring System 2020

Published by Federal Highway Administration (FHWA) | Department of Transportation | Catalog Last Checked: July 31, 2026 at 08:40 PM | Dataset Last Updated: May 05, 2025 at 12:00 AM
The Highway Performance Monitoring System (HPMS) 2020 dataset was compiled December 31, 2020 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 file geodatabase download provides HPMS data for each state as an individual feature class. This dataset represents the highway system as of the 2020 calendar year. HPMS provides data that reflects the extent, use, condition, and performance of the public roads in the United States. It consists of the All Road Network of Linear Referenced Data (ARNOLD) geometry and the Section Data which is the attribution. ARNOLD and Sections are linked though linear referencing and are part of the HPMS data program. These data are analytical for the purpose of supporting transportation programs, funding and policy decisions at a national level. Operational applications such as navigation and routing may take advantage of HPMS with the understanding that it represents the average and not “real-time” of the system. The Highway Performance Monitoring System Field Manual contains a detailed description of each data element including coding instructions and attribute definitions. The Field Manual is available at: https://doi.org/10.21949/1519108. A data dictionary, or other source of attribute information, is accessible at https://doi.org/10.21949/1519108
