Paper summarised the proposals of fourteen new alternative indexes intended for road roughness evaluation of longitudinal road profile, which have been introduced in the last decade approximately. The main advantages of proposed indexes are: (1) effort to reflect the most of ride quality aspects such as ride comfort, ride safety and dynamic load of road or cargo; (2) using the in situ measurements of vibration response or subjective perception of vibration; (3) effort to reflect the vehicle responses such as roll and pitch vibration, or longitudinal and lateral vibration; (4) effort to detect the critical parts of road in a spatial domain; and (5) effort to reflect a vehicle velocity. The main limitations of proposed indexes are: (1) many proposals are only alternative to the international roughness index (IRI) or are based on the IRI procedure; (2) a simple one-dimensional vehicle model is often used with the constant parameters and velocity; and (3) orientation to one vibration response category as ride comfort.

“…Further, Prigogine and Lewis et al defined entropy as a measure of ignorance [37], regarding the gain in entropy as loss of information [38]. In transportation-related research, Baslamisli et al proposed an approach to identify the surface type of road by calculating the entropies of the sprung mass vertical acceleration of a vehicle running over roads with different qualities [39]. Tan et al used the entropy of driver steering angle to measure discontinuity and to evaluate the effectiveness of drivers' steering controls to distinguish driving skill levels [40].…”
