Roads & Highways

LAIRA's road and highway matrices cover the regulatory frameworks that govern federal-aid, state, local, and DoD-installation roadways, plus parking lots. The core compliance methodology is ASTM D6433 for the PCI surveys, FHWA 23 CFR Part 490 for federal performance reporting, and AASHTO's automated-method standards for the underlying measurement procedures.
