Highway Performance Monitoring System (HPMS)

The Highway Performance Monitoring System (HPMS) program is a national highway information system that monitors data on the extent, condition, performance, use, and operating characteristics of the nation's highways.

HPMS data is used extensively at the federal level in the analysis of highway system condition and performance, but more importantly in the appropriation of Federal Highway dollars and in support of federal efforts to secure increased transportation funding.

Code of Federal Regulations Title 23 Part 500.203 sets the general requirements for the state's data collection program. It directs that each state develop and implement a Traffic Monitoring System for Highways program on all roads receiving federal funds.

Non Trunkline Federal Aid Road Program (NTFA)
The NTFA program is part of the State of Michigan's Traffic Monitoring program. It was established in 2010 and is a cross-agency traffic data collection program. This program was an expansion of existing requirements set forth by the Federal Highway Administration's (FHWA) HPMS program.
