WebDifferent models of road roughness have been widely studied in the literature [19–26]. These models can be classified into two main categories. The first category relies on simulations of roads with parameters that can be adjusted to change the simulated road roughness, while the second relies on measurement taken from actual roads. WebJan 28, 2009 · The coherence function between road roughness in left and right wheel-path is studied. Empirical coherence functions are computed from 20 measured roads, with a total length of 520 km. It is found that the coherence estimates are similar, despite the wide range of studied road types. A one-parametric model, which describes the coherence …
