A newly introduced comfort indicator was defined as the discomfort criterion (DiC). Based on several real-life driving scenarios and realistic assumptions. This criterion identified the comfort of a vehicle quantitatively, and therefore, it is possible to compare different types of vehicles in terms of ride comfort. The criterion was proposed in accordance with part one of the ISO 2631standard for mechanical vibration and shock evaluation of human exposure to whole-body vibration. Also, road surface conditions were extracted from ISO 8608 for mechanical vibration road surface profiles by applying the power spectral density (PSD) of a specific road class. Knowing that during the ride of a vehicle, occupants are exposed to vibrations from the road surface which causes the feeling of discomfort, reduces working ability, which i
