Fig.3. Picture of one of the mounted accelerometers (triaxial no. MP01).

In figure 4, from a set of recorded acceleration time histories three windows of 50 seconds were extracted and displayed to show differences among test tracks in terms of induced acceleration.

Fig.4. Time histories comparison among three road tracks (arbitrary windows of 50 s are considered for each track).
