초록
The prospect of the highway traffic road construction has led to resistance from residents, partly based on noise and vibration issues. Particularly, as tracks often pass closely to residential dwellings, constructors are then required to take account of noise and vibration. So the prediction of noise and vibration for highway traffic is very important thing. The highway traffic noise and vibration make one specific issue. For the highway traffic road, this paper concerns the noise by the wheel/tire and the structure-borne noise by the road. Based on the results, this paper proposes the source model of highway traffic noise and the calculation model for highway traffic noise. Also prediction model is presented with traffic noise which are calculated by considering the power level of a source for one-third octave band, ground absorption and barrier deflection. A lot of empirical data is needed to predict the noise and vibration. And one of the best ways to control the wayside noise is to analyze the noise level.
