Abstract: A method for measuring a vehicle moving on a roadway, in particular a bridge, by means of at least one sensor measuring the deformation under load of the roadway includes recording the time curve of the sensor-measured value while the vehicle moves past the sensor; repeating a minimization, in which a measure of the deviation from the recorded curve by a parametrized reference function comprising a sum of a number of rational functions is minimized by adapting the parameters thereof, wherein a different number is used in every repetition and, in fact, as often as necessary until the deviation measure falls below a limit value, and then selecting the reference function associated with this deviation measure as the selected reference function; and determining the number of rational functions of the selected reference function as the number of axles of the vehicle.
