... is applied. For U.S. highways, the autocorrelations of the terrain profiles do not decay, which indicates a highly correlated, autoregressive process. Figures 1 2 illustrate a typical U.S. highway profile and its corresponding autocorrelation function. The measured profile shown in Fig. 1 exhibits...
