Abstract

This study examined how the emissions of pollutants affect the volume of traffic of freight vehicles in the transport sector. Multiple regression analysis was conducted considering several variables, including population by region, area of urban district, GDP, and the number of businesses by industry, e.g., agriculture, forestry, fishery, manufacturing, wholesale, and retail. These variables differ according to the characteristics of the freight vehicles (industry, by the ton). Therefore, it is essential to fully consider the volume of traffic of the specific freight vehicles by region before implementing relevant programs and policies, such as specific restrictions on the operation of vehicles. Some specific areas, in which logistic centers are located have heavy freight traffic, and these centers deserve extra consideration. Thus, in this study, different regional factors that affect the traffic of freight vehicles should be considered before determining the areas that will be subject to restrictions on the operation of these vehicles.

본 연구는 수송부문에서 오염물질 배출 비중이 큰 화물차의 통행량에 영향을 미치는 요인을 분석하기 위하여 다중회귀모형을 추정하였으며, 모형 추정 결과 지역별 인구수, 도시지역 면적, GDP, 업종별(농업, 임업 및 어업, 광업, 제조업, 도매 및 소매업) 사업체수 등이 주요 변수로 검토되었다. 이러한 변수는 화물차 특성(업종, 톤급)에 따라 상이하게 나타나므로 차량 운행제한 등 관련 정책 추진 시에는 지역별 화물차 특성에 따른 통행량을 충분히 고려해야 할 필요가 있다. 특히 물류터미널 등 화물차 통행량이 많은 물류거점이 위치하지 않은 지역에 대해서는 화물차 통행에 영향을 미치는 지역별 요인을 고려하여 차량 운행제한 대상 지역을 검토해야 할 필요가 있다. 특히 본 연구의 결과에서 제시된 바와 같이 화물차 통행량과 지역 내 인구수는 양의 상관관계를 가지기 때문에 인구밀집지역에서는 화물차를 포함한 차량운행제한 검토가 필요하다. 본 연구 결과의 신뢰도를 높이기 위해서는 실제 통행량 자료를 기반으로 다중회귀모형 외 다양한 모형 추정을 통하여 추정 결과에 대한 오차를 줄여야 할 필요가 있다.
