현재 국내 대도시권은 도시의 외연적 확장과 도로 중심의 교통물류체계 및 통행패턴으로 인하여 도로운송 시스템은 이미 포화상태에 도달하여 교통 혼잡으로 인한 물류비용의 증가, 도로 시설 유지보수 비용 증가 등 사회 경제적 비용 부담이 가중되고 있다. 화물운송시스템도 도로운송에 의존하고 있어 이산화탄소의 배출량이 많아 대기오염의 주된 요인으로 작용하며, 야간 운송에 따른 소음 유발, 교통사고 발생, 도로파손 등 사회문제를 야기하고 $\cdots$(중략)$\cdots$.

Traffic noise cost can be assessed either by the damage cost approach or by the avoidance cost method. This paper provides an overview of pertinent studies of these two approaches and shows that the damage cost approach is more universal and reliable than the avoidance cost counterpart. This study then investigated three sub-components to address the damage cost framework. First of all, unit value per person exposed to noise per year was calculated. Secondly, the area exposed to noise was determined using noise prediction equation. Thirdly, the number of people affected by noise was computed by multiplying the number of people exposed to noise with the percentage of people affected by noise. This paper also suggested a simplified equation that represents the relationship between damage costs and noise levels. Finally, the benefits of noise reduction derived from the damage cost method and those from the avoidance cost approach were compared and discussed.

A series of research to seek for the relationship between subjective responses and noise level for transportation noise have been proceeded, and their results showed similar for some cases and different for some other cases as well, which is considered due to the various conditions such as the way of survey, different scale applied, and country etc. This study aimed to analyze the relationship between sound level and subjective response for the different kinds of transportation noise. The noises recorded in real situation were played to thirty subjects with fourty nine adjectives. The percentage of people annoyed(% PA) and the percentage of people highly annoyed(% HA) were calculated from the subjective results and compared how many percent of people are annoyed and highly annoyed for the same sound level. As a result of calculating the average, the aircraft noise was highest and the white noise lowest. The relationship between window TL and average point was well correlated except the aircraft noise which was scattered because of high sound level at specific frequency and low TL at corresponding frequency. This means that appropriate rating method for airborne sound transmission should be sought for to evaluate outdoor noise which has different frequency characteristics. The Boltzmann equation for % PA and % HA was applied to predict the sound level corresponding to the percentage. It is concluded that the aircraft noise and road traffic noise have almost same response and the railway noise was same with white noise, used for the reference noise, annoyed lower than other noises about by 3 dB.

With the increase in discomfort of living by serious traffic noise pollution, the desire of relieving from discomfort is boosted up more than ever. For this reason, the researches on environmental impact assessmient and noise pollution control are highly required. This research was aimed to analyze the physical characteristics of noise caused by high-speed train in foreign countries by literature survey and field data. And with the attained results, the exterior noise level around Chon-An station, the first station planned for the high-speed train in this country, was estimated. The results of this study might be used as a tool for predicting the unavoidable noise, lessening the noise impact caused by the high-speed train, and preparing the noise prevention measures for the interior space and the exterior around stations.

In the Well-being age, many people use a city park for rest deeply think and constitutional walk. The city park is located at near side by traffic road in urban. Citizens are not satisfied with it's fuction as a haven of peace due to road traffic noise. Thus, this study is for a research on the actual noise condition of a city park in Nowon go. This study uses a prediction method called ASJ-model in order to calculate PWLs of road traffic noise. Using calculated PWLs, noise levels in a park are predicted and compared with measured values.
