BETA - Highway Performance Monitoring System 2023
The BETA release of the Highway Performance Monitoring System (HPMS) 2023 dataset was created using the most current data as of August 17, 2024 by 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). The data represents a snapshot of extent, usage, condition, and performance as of December 31, 2023. This file geodatabase download provides HPMS data for each state as an individual feature class. 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 âreal-timeâ 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.
