Definition
Federal Highway Administration Highway Performance Monitoring System. Requires state DOTs to report IRI, cracking percentage, rutting depth, and faulting for NHS roads. Road Triage delivers the cracking percentage metric via smartphone collection. With SSI profiler hardware (Enterprise Tier), all four HPMS metrics are captured from a single survey pass.
In context
State DOTs report cracking, rutting, faulting, and roughness to FHWA HPMS each year.
