An analytical model is presented for calculating the power spectral density of relatively short wavelength guideway irregularities associated with surface roughness. The results are presented in terms of design tolerances which can be interpreted in terms of the familiar California profile index or in terms of measurable deviations from a straight edge. Digital computer numerical simulation techniques are used to verify the model.
