Usage can include distance traveled, optionally associated with particular ranges GC of speed or road type. In a calibration phase, auxiliary measurements, for instance based on GPS signals, are used to determine a 0 relationship between the vibration signal and usage. In a monitoring phase, the determined relationship is used to infer usage from N the vibration signal.
