Abstract: A method for monitoring road conditions includes measuring a vehicle movement quantity associated with a present road condition. A respective position at which the measuring was performed is recorded. A road condition class is assigned to each of the positions by comparison with type calibration data. The type calibration data is pre-defined relations between vehicle movement quantities and road condition classes for a specific type of measuring unit and for a specific type of vehicle. The positions and assigned road condition classes are stored in a road condition database. A consolidated road condition class is determined for a target road section, by forming a distribution of stored road condition classes for positions within the target road section and selecting the consolidated road condition class to be representative for the distribution of road condition classes. The consolidated road condition class for the target road section is presented.
