摘要：AbstractWith an increasing number of PTs and SUVs on the roadways nowadays, it is hypothesized that traffic noise would go up because the size of these vehicles and the tires used are generally larger than those of the passenger cars. This study investigates the noise impact due to these vehicles by collecting and analyzing field data. A comparison is made with the existing FHWA Traffic noise model and significant differences are found between the field measured noise data and the calculated values from the model.
