Computed Parameters

Computed parameters are engineering parameters or summary statistics derived from the raw LTPP data, e.g., IRI (derived from longitudinal profile data), various rut indices (derived from transverse profile data), or backcalculated moduli (derived from pavement deflection data and supplemented by pavement cross-section information. The availability of computed parameters will expedite and improve the efficiency of many future analysis projects.
