Vibration generated by highway traffic is a significant form of environmental pollution that has not been studied as comprehensively as noise pollution. Vibration sources and the mechanisms of vibration propagation and attenuation must be better understood before uniform criteria for vibration pollution and corrective measures can be established. The theory of ground-borne vibration provides considerable insight into the nature of traffic-induced vibration. The relevant theory and associated experimental data have not heretofore been put into a form useful to highway engineers and transportation scientists not trained in the problem area. The highway irregularity spectrum is the most important cause of vibration. The Rayleigh wave is of primary importance to traffic-induced vibration assessment. Significant structural damage from traffic- induced vibration is rare. However, human response to vibration is both physiological and psychological, and human often classify vibration as unacceptable at levels lower than those that cause structural damage. The nature of the long wave lengths of traffic-induced vibrations makes it unlikely that attenuation measures such as trenches will be successful. Indications are that careful maintenance of the highway will be the most effective vibration preventive and that special abatement measures will be used only whete complaints have occurred.
