چکیده انگلیسی
In road roughness literature different stochastic models of parallel road tracks are suggested. A new method is proposed to evaluate their accuracy, by comparison of measured parallel tracks and synthetic parallel tracks, realized from a stochastic model. A model is judged accurate if synthetic and measured roads induce a similar amount of fatigue damage to a vehicle. A lack-of-fit measure is assigned to the evaluated models, facilitating a quick and simple comparison. The uncertainty of the vehicle fatigue indicated for the measured profile is considered in the definition of the lack-of-fit measure. A bootstrap technique is applied to estimate the uncertainty.
