U.S. Highway Performance Monitoring System 2023 Beta Snapshot

A beta release of the Highway Performance Monitoring System (HPMS) 2023 dataset, created by the Federal Highway Administration as of August 17, 2024. The data provides a snapshot of U.S. highway extent, usage, condition, and performance as of December 31, 2023, for national transportation program and policy analysis.

Use Cases

• Analyze highway condition and performance metrics to inform national transportation funding decisions.
• Study the extent and usage of the All Road Network of Linear Referenced Data (ARNOLD) geometry for infrastructure planning.
• Link ARNOLD geometry with Section Data attribution through linear referencing for spatial analysis of highway sections.
• Support analytical applications for national policy, understanding the data represents system averages, not real-time conditions.

Strengths

• Data is a national snapshot as of December 31, 2023, providing a consistent temporal reference point.
• Created by the authoritative Federal Highway Administration (FHWA) and part of the National Transportation Atlas Database (NTAD).
• Includes both linear geometry (ARNOLD) and detailed attribution (Section Data) linked for comprehensive analysis.

Limitations

• Dataset is labeled as a beta release, indicating potential instability or changes before a final version.
• Data represents system averages and is not suitable for real-time operational applications like navigation.
• Specific data volume metrics such as row count, column count, and file size are unknown.
