The Highway Performance Monitoring System (HPMS) is a national level highway information system that includes data on the extent, condition, performance, use and operating characteristics of the nation's highways. The HPMS contains administrative and extent of system information on all public roads, while information on other characteristics is represented in HPMS as a mix of universe and sample data for arterial and collector functional systems. Limited information on travel and paved miles is included in summary form for the lowest functional systems.
HPMS was developed in 1978 as a continuing database, replacing the special biennial condition studies that had been conducted since 1965. The HPMS has been modified several times since its inception. Changes have been made to reflect changes in the highway systems, legislation, and national priorities, to reflect new technology, and to consolidate or streamline reporting requirements.
The Michigan Department of Transportation (MDOT) is responsible for the collection of data to the Federal Highway Administration (FHWA) as outlined in the Overview of the HPMS for FHWA Filed Offices – April 2003 Primer.
MDOT requests annually for their transportation planning partners in both the Urban and Rural Transportation Programs to assist in this data collection effort utilizing the HPMS Guidelines and the HPMS Field Manual as a guide.
