    • HPMS Spatial All Sections - 2024

    Metadata Updated: December 26, 2025

    A GeoJSON file with all spatial roadway data for all sections from the 2024 Highway Performance Monitoring System (HPMS) attached to the All Road Network of Linear Referenced Data (ARNOLD) network. This file was produced using what is known as the “Spatial Full Join” process in HPMS, which is a spatial dynamic segmentation of the HPMS data to create homogeneous roadway sections. To be included in the file, only one data item must be present on a section of road. See attached README file for more details.
