도시 중심가를 오가는 전동차의 경우 도시 사이를 운행하는 일반 기존선과는 다른 소음 특성을 가진다. 가장 두드러진 특징으로는 일반 기존선은 주로 디젤기관(디젤전기기관차 포함)에서 얻어지는 추진력을 이용하여 운행되나 도시철도에 사용되는 전동차의 경우는 그 추진력을 공급된 전기에너지에 의해 그 추진력을 얻는 것이다. 따라서 주요한 소음원의 특성도 상이하며, 또한 개활지를 중심으로 운행되는 기존선 열차에 반해 도시 전동차는 주로 터널내부에서 운행되고 있다. 따라서 본 연구에서는 도시 전동차의 소음원의 특성에 대해 측정 사례를 중심으로 나타내었다.

"바람직하지 않은 소리", "불쾌한 소리"로 총칭되는 소음은 현대산업에서 만들어지는 많은 환경적 오염물질(오염원)중의 예이다. 전체 인구의 60%이상은 매일 소음환경에 노출되고 있으며 도시 내 소음도는 10년마다 배로 증가하는 추세이다. 도시지역 신경질환의 70%는 소음이 그 원인이며, 각종 피해증상(수면부족, 두통, 불쾌감, 불안감, 소화불량, 신경질 등)의 호소가 급증하고 있다. 공항지역(86~91dB) 주민의 50%가 불쾌감이나 정서적 불안을 느끼는 것도 소음에서 기인한다.(중략)끼는 것도 소음에서 기인한다.(중략)

이동의 편리함과 주행안정성을 주기 위해 개발된 도로가 소음을 발생시켜 운전자 및 소비자의 쾌적성을 저해하는 요소로 작용하고 있다. 이러한 문제를 해결하기 위해 연도거리확보 또는 방음벽 등의 소음억제 방법을 사용하고 있으나 미관을 저해하고 용지사용이 비효율적이어서 외국의 경우 저소음 포장 연구를 통한 근본적은 소음 발생원을 차단하기 위한 노력이 진행되고 있다. 국내에서도 신도시 개발 등으로 도로건설에 따른 급속한 교통량 증가 및 차량의 고속주행으로 인하여 도시소음의 주요인으로 부각되고 있고 시민들의 높은 생활수준과 소음 환경에 대한 기본생활권 추구 성향이 증대되어 지역 주민의 교통소음 저감 대책 및 보상에 대한 법적 소송이 빈번히 발생하고 있어 차량 주행 소음 저감을 위한 방법으로 방음벽 설치가 널리 사용되고 있으나 이는 경제적 손실뿐만 아니라 도시미관을 해치는 문제가 발생하고 있다. 도로사업의 환경성 강화는 국토해양부의 2009년 주요도로정책 중 하나일 정도로 국가정책의 중요한 지침으로써, 향후 추진되는 신도시 및 단지조성공사 시 도로 환경성과 소음, 진동, 그리고 생태통로에 대한 친환경 도로설계 및 시공 등에 적절히 대응하기 위하여 교통소음을 개선하기 위해서는 교통소음 발생 요소를 파악하고 신도시 및 단지조성시 주변도로에 친환경적 포장공법 설계기술의 개발 및 적용을 위한 단계적 연구가 필요하다. 따라서 본 연구에서는 친환경 저소음 포장공법의 종류에 대하여 알아보고자 한다.

Depending on the transportation, information and communication technology development, urban such as the superficial spreading and the changing structure of internal space of the organism has various shape and speed of the changes. In particular, the main cause of these changes is the development of the traffic and this transport system is having a close connection with land use. This study presents the results about characteristics and changes of noise on each land use zoning. Therefore the result shows that the measured data could be used to evaluate noise distributions on urban land use and then make up the basis process for producing noise maps of land use zoning.

Noise pollution on the residential areas adjacent to urban expressway is a very severe situation. There has been a significant increases in the number of residential areas near urban expressway, and the quality of life in such areas is being degraded due to increased traffic volume and speed. In this study, several factors such as traffic volume, speed, and distance from noise source, etc. that affect the noise level were investigated for the residential areas near urban expressway. A correlation and regression model was built to examine the relationship between such traffic factors and noise. The study result found that traffic volume had a closer relationship with noise than speed had. Therefore, to decrease road traffic noise, it is more imperative to control traffic volume than traffic speed.

Increasing population in the cities, it has been demanded that urban planner should consider environmental problem. In this regard compact city has been strongly suggested as an environmental urban form which can reduce energy consumption. However, compact city can also cause noise problem, because residential buildings have to be located near roads and railways. In order to solve this problem, it is necessary for urban planner to examine the types of roads and railways before they are established. Noise map is able to be useful tool for the task.

The noise problem became more serious by the rapid urban population growth and traffic. This study estimates the noise level considering actual traffic volume and building shape and location. Based on the state of the arts noise level, changing amount of noise that was controlled by the speed control and truck and passenger car restriction is calculated. Some conclusion is found out. The 2-D type more than 3-D type is more than over standard of noise pollution and night time's over rate is larger than day time. And in the case of various solutions are used instead of applying one solution, noise pollution is effectively reduced.

Traffic noise pollution is a growing problem that highly affects the health of people in urban areas. In order to implement effective measures against traffic noise the noise mapping about its distribution is imperative. Urban traffic noise maps will help to establish the existing baseline so that we will be able to look for the effective way to control the noise. They will also let us see in an understandable and visual way how noise spreads from roads into residential areas. In this paper we considered three development types between roads and residential areas, and applied the interpolation of ArcGIS for noise attenuation with distance from the roads to find the noise level at the parcels positions in residential areas, and then generated the noise map using the interpolated results. Therefore we present results that the traffic noise level within residential areas exceed the national noise standard and also can estimate the noise level of individual parcels. These results can be used for traffic noise control planning or assessment of officially assessed land price in near future.

Noise and air pollution, which accompany the development of industry and the increase of population, contribute to the deterioration of urban environment. The air pollution level of Seoul has gradually increased and the city residents are suffering from a high pollution of noise. If no measures were taken against pollution, the amount of emission of pollutant into air would be 36.7 thousand tons per year per square kilometer in 1975, three times more than that of 1970, and it would be the same level as that of United States in 1968. The main sources of air pollution in Seoul are the exhaust has from vehicles and the combustion of bunker-C oil for heating purpose. Thus, it is urgent that an exhaust gas cleaner should be instaled to every car and the fuel substituted by less sulfur-contained-oil to prevent the pollution. Transportation noise (vehicular noise and train noise) is the main component of urban noise problem. The average noise level in downtown area is about 75㏈ with maximum of 85㏈ and the vehicular homing was checked 100㏈ up and down. Therefore, the reduction of the number of bus-stop the strict regulation of homing in downtown area and a better maintenance of car should be an effective measures against noise pollution in urban areas. Within the distance of 200 metres from railroad, the train noise exceeds the limit specified by the pollution control law in Korea. Especially, the level of noise and steam-whistle of train as measured by the ISO evaluation can adversely affect the community activities of residents. To prevent environmental destruction, many developed countries have taken more positive action against worsening pollution and such an action is now urgently required in this country.
