Abstract :

The investigation of road vehicle dynamics has to take into account the influence of road irregularities. To do this various road profiles have been surveyed. Samples of road profile heights can be used as input of vehicle dynamics simulation or to fit appropriate random road models to the data. For supporting this modeling part the paper presents some statistical characteristics of a number of road profile samples.
