Road surface description forms the basis of vehicle response prediction, but in most cases precise description of a particular road is of less value than a description representative of a class of roads. In these circumstances an analytical road surface model has special advantages. In modelling a road surface, rather than a single road profile, the hypothesis of isotropy is shown to provide a useful basis, and the paper shows how a particular profile spectral density, together with the assumption of isotropy, can be used to define an effective surface model. Coherence functions derived from the proposed model are validated by comparison with coherencies based on measurement. /Author/TRRL/
