4.1 These practices provide a means for evaluating traveled surface-roughness characteristics directly from a measured profile. The calculated values represent vehicular response to traveled surface roughness.
4.2 These practices provide a means of calibrating response-type road-roughness measuring equipment.4
1.1 These practices cover the calculation of vehicular response to longitudinal profiles of traveled surface roughness.
1.2 These practices utilize computer simulations to obtain two vehicle responses: (1) axle-body (sprung mass) motion or (2) body (sprung mass) acceleration, as a function of time or distance.
