This document summarizes the history and capabilities of the ProVAL longitudinal profile analysis tool. It discusses how ProVAL has evolved from early profiling devices in the 1940s-1980s to current inertial and 3D profilers. It then outlines ProVAL's profiling analyses, import/export capabilities, and technical support. ProVAL is sponsored by FHWA and the LTPP program and allows users to view, analyze, filter and simulate profiles for various applications like ride quality, grinding, fault measurement and WIM site location.
