Highway Performance Monitoring System (HPMS) - Tables

<b>Description from the original website</b><br><br>The Federal Highway Administration (FHWA) has been receiving Highway inventory, usage, condition and performance data from State Departments of Transportation (DOT) since 1978 to support the program mission of the FHWA. Specifically, HPMS consists of detailed road segment data for higher order systems, sample attributes for collector systems, and summary data for the local roads.<br>States DOTs submit HPMS data annually to the FHWA following a prescribed format outlined in the HPMS Field Manual. New requirements for HPMS took effect in 2014 that required State DOTs to expand their Linear Referencing Systems (LRS), a statewide geospatial representation of their road system that includes all public roads. This requirement was put in place to support highway safety.<br>HPMS public data consists of geospatial reference files and several tables (County Summaries, Urban Summaries, Statewide Summaries, Non-Federal Aid Summaries, and Roadway Sections). Also included in the HPMS public data is the Sample Table. State Departments of Transportation provide these data tables every June following the data year it represents. Generally, these files will be available to the public by September, after FHWA's review and acceptance of the data. The FHWA does not alter the data provided by State DOTs other than removing data that fails basic format violations. <br>The following views of HPMS are intended to provide flexibility for different user groups to effectively analyze the data in HPMS in the most efficient manner.<br><br><b>Comments</b><br><br>The HPMS data sets are split into three parts. The first part are geospatial data for the years of 2018 to 2024 (https://www.datalumos.org/datalumos/project/240301/version/V2/view). The data sets are provided in geopackage (gpkg) format. The Data Element Dictionary and HPMS Field Manual are included there. The second part comprises the years 2011 to 2017 and are in shape file format (https://www.datalumos.org/datalumos/project/240303/version/V1/view). This data set here is the third part, tabular data provided as CSV. <br><br><br><br>
