  • 자동차에 의해 발생되는 도로교통소음을 예측할 수 있는 기본모델을 개발하고저 한다. 이를 위 해 기존도로중에서 통행방법 등을 조사하고저 통행량, 속도등의 통행방법 및 측정거리가 조사되었고, 소 음평가량으로서 등가소음수준 Leq와 소음수준 중앙치 L\sub 50\도 측정되었다. 본 연구에서는 이와 같 은 자료를 토대로 측정된 자료를 토대로 선형회귀분석 방법을 사용한다. 이렇게 개발된 모델을 동일한 조건에서 실측된 자료에 적용한 결과 정확도가 상당히 높았다. 다른 지역에서 이미 개발된 모델로서는 수학적인 모델과 통계적인 모델들이 있다. 이미 개발된 모델들과는 실측치와 예측치와의 오차의 제곱을 합계한 값으로서 비교했다.

  • Because many people suffer from physical and mental damage caused by the noise created by transportation infrastructure, including road traffic, rail, and aircraft, developed countries have conducted research on predicting and solving the impact to human health from being exposed to transportation noise. Therefore, this study suggests a fundamental plan to assess the health impact of transportation noise on the basis of domestic and foreign prediction results regarding the health impact of transportation noise. The domestic and foreign exposure-response expressions, including the noise index and the health impact indicator of annoyance and sleep disturbance, are compared, and it is found that domestic individuals show a more sensitive response to transportation noise. Based on domestic and foreign research, and a case study regarding the health impact of transportation noise, a fundamental plan to assess the health impact of transportation noise comprises the preparation of objective assessment standards through the improvement of exposure-response models, and the establishment of reduction measures which can improve the quality of the transportation noise environment.

  • Domestic economic development, industrialization, and urbanization have brought along not only increased highway traffic but also elevated traffic noise levels. Thus, it is necessary to accurately predict the traffic noise levels in order to address the public demand of alleviating the noise levels in urban areas. In this study, the method of evaluating the sound power level of road traffic was investigated in terms of considering the types of road surface and vehicle, based on previous researches. Regarding CPX (Close Proximity Test) and Pass-by test, the measured noise data of Test Road of Korea Highway Corporation were utilized in order to construct the database of sound power levels of various vehicles. Specifically, the 38 noise measurement and analysis in 1/1-octave band frequencies at 12 pre-selected sites were carried out, considering topography and road surface. Finally, the comparison study was conducted between predicted and measured data in terms of traffic noise. The traffic noise prediction was based on the KRON (Korea Road Noise) program, which was developed being equipped wit 3-dimensional GUI. In addition, the traffic noise characteristics were evaluated in terms of vehicle types and pavement surface conditions.

  • 고속도로에 아스팔트 저소음포장이 시공된 현장의 소음조사를 통하여 저소음 아스팔트 포장의 소음저감효과를 분석하였다. 교통량 및 시공시기에 차이가 있는 세 현장에 대하여 측정 시기를 달리하여 저소음포장의 사용 기간에 따른 소음저감효과의 변화를 분석하였으며, 공동주택의 소음대책을 위해 시공된 현장에서는 세대내에서 실질적인 저감효과에 대해 분석하였다. 이 결과를 토대로 저소음포장을 도로소음 대책수단으로 적용을 검토할 경우 설계자가 고려해야할 사항을 제시하고자 하였다.

  • The noise map has been applied to predicting the effect of noise and establishing the noise abatement measure for several years overseas. However the introduction of the noise map in Korea is at the initial stage. Thus, we surveyed the several prediction models for road traffic noise used in EU, and the method of applying the noise map in noise impact assessment. In order to improve the noise impact assessment we have to apply the noise map, and propose the guideline of predicting the road traffic noise. We intend to obtain coherency and accuracy of prediction results. As a result of this study, we know that the prediction guideline is an essential prerequisite in order to predict the unified and accurate road traffic noise.

  • 고속도로 교통 소음 저감을 위해 상용소음예측프로그램인 SoundPLAN과 소음예측 시 주로 사용하는 도로 교통 소음예측식인 RLS-90을 이용하여 경제적이고 효율적인 방음대책 설계방안에 대한 연구를 하였다. 대상지역에서 측정한 실제 소음도와 예측 소음도의 차이를 비교하여 모델을 검증하고 장래교통량에 대하여 소음을 예측하여 방음대책을 설계하였다. 방음벽의 높이와 길이, 저소음 포장의 길이를 조절하고 저소음 포장과 방음벽을 혼용했을 경우에 대하여 소음규제 기준에 적합하게 설계하였고 각각의 설치 단가를 이용하여 경제성을 비교하여 보다 효율적인 방음대책을 알아보았다.
