The Highway Performance Monitoring System (HPMS) is the official Federal government source of data on the extent, condition, performance, use, and operating characteristics of the nation’s highways. HPMS data are used for assessing and reporting highway system performance under FHWA’s strategic planning process. HPMS data also forms the basis of the analyses that supports the Conditions and Performance Report to Congress and are the source for a substantial portion of the information published in the annual Highway Statistics publication and in other FHWA publications including information that is reported to the media. Importantly, HPMS is the primary source of transportation data that FHWA uses to determine Alaska's share of millions of dollars in annual federal transportation funds.
Each state is required to prepare an annual submittal of HPMS data in accordance with the procedures, formats, and codes specified in the FHWA HPMS Field Manual. Submittals are due June 15th of each year and they include data representing the prior calendar year.
HPMS has nearly 70 data fields, some of the important ones include:
