... • Traffic noise prediction models updated using the noise source distributions obtained in the current study can serve as a resource for state and federal agencies to examine the effectiveness of highway noise mitigation strategies, such as the use of quieter pavements or barrier design. • Novel information obtained for noise source distributions on trucks, as well as the measurement technique developed in the course of the study, are recommended to truck manufacturers for further studies of potential source- or pathtargeting treatments.

... cycles, as well as other noise sources such as construction equipment, etc. • The approach developed in the study can be used for exploring in greater detail the effects of varying pavement types and terrains on noise generated by different vehicle types, including the effects on vertical noise source distribution and tire–pavement interaction.
