Effects of measurements method for vehicle speed on thee prediction results of noise map

차량속도 측정방법이 소음지도 예측결과에 미치는 영향

Noise map presents new alternatives of noise reduction counter measure and becomes important tool for making environmental policy. Many input factors such as road conditions, number of vehicles, speeds of vehicles are used for noise prediction of the noise map. However, results of noise prediction make difference depending on the values of the input factors. In this study, effect of measurement method for vehicle speeds all the prediction results of the noise map.
