Effects of Vehicle Classification Methods on Noise Prediction Results of Road Traffic Noise Map

소음지도 제작 시 차량 분류방법이 소음도 예측 결과에 미치는 영향 연구

Road traffic noise map is effective method to save cost and time for environmental noise assessment. Generally, noise is calculated by using theoretical equation of noise prediction, and the calculated result can be influenced by various input factors. Especially, domestic vehicle classification method for traffic flow and heavy vehicle percentage is different from that of foreign countries. Thus, this can cause effect on the noise prediction results. In this study, noise prediction results by using domestic vehicle classification method are compared with those by foreign methods.
