Abstract

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.

도시고속도로 주변 지역에 인접한 주거지역의 도로교통소음은 매우 심각한 실정이다. 도시고속도로 주변의 주거지역은 90년대 들어 크게 증가하였으나 많은 교통량과 높은 속도로 인해 거주민들의 삶의 질은 계속 저하되고 있다. 본 연구에서는 이러한 도시고속도로 주변의 주거지역에 대해 교통조건을 고려한 소음도에 영향을 미치는 인자(교통량, 속도, 수음점에서의 거리 등)에 대해 고찰하였다. 소음도에 대한 교통량과 속도와의 관계를 고찰해보기 위해 이 식에서 주요 요인으로 사용한 교통량과 속도의 두 요인 중에서 무엇이 더 큰 영향을 가지는지를 상관관계 분석과 회귀분석을 통해 교통량이 속도보다 더 밀접한 관계가 있음을 알 수 있었다. 따라서, 도시고속도로 구간에서 도로교통소음을 저감하기 위해서는 차량의 속도도 중요하지만 근본적으로 교통량을 저감하기 위한 대책이 더 중요하다고 볼 수 있다.
