Vehicle overloading is a significant factor in the degradation of road surfaces. The analysis of sensor data is particularly complicated when dealing with multiple parallel lanes and vehicles with many axles.
The algorithm enables the signals received by WIM sensors to be assigned correctly to individual axles and axle groups, even when parallel moving lanes fail to stay perfectly in lane. The analysis does not require estimation of influence lines. The data are stored in compressed form and can be rapidly retrieved.
