Abstract

Atmospheric pollutants such as Nitrogen Oxides(NOx), Carbon Monoxide(CO), Carbon Dioxide($CO_2$), Particulate Matter(PM) and Hydrocarbons(HC) come from vehicle exhaust gases. Emission curves based on average travel speeds have been employed for estimating on-road emissions as well as evaluating environmental impacts of transportation plans and policies in Korea. Recently, there is a growing interest in estimation methods of vehicle emissions considering relationship between vehicle dynamic driving characteristics and emissions, and incorporating such emission estimators into traffic simulation models. MOVES Lite, a simplified version of MOVES, is one of the estimation methods. In this study, the authors performed a study to develop an adaptable version of MOVES Lite for Korea, called MOVES Lite-K. Vehicle types, driving characteristics, emission rates, and emission standards of Korea were reflected in MOVES Lite-K. The characteristics of emission calculation of MOVES Lite-K and NIER emission curves were compared and the adaptability of MOVES Lite-K were examined.

차량의 배기가스에는 질소산화물(NOx), 일산화탄소(CO), 이산화탄소($CO_2$), 입자상 물질(PM), 탄화수소(HC)와 같은 대기 오염물질이 포함되어 있다. 이러한 도로이동오염원의 배출량을 산정하기 위하여 한국에서는 평균속도 기반의 배출계수 곡선식을 사용하고 있으며 교통 계획과 교통 정책의 대안 평가에서 환경적 영향을 분석할 때 활용하고 있다. 그러나 최근에는 차량의 동적 운행 특성과 배출량의 관계를 보다 정확하게 반영하여 배출량을 산정할 수 있는 방법론과 이 방법론을 교통 시뮬레이션 모형에 통합하는 것에 대한 관심이 증가하고 있다. MOVES Lite는 MOVES의 간략 버전으로서 교통 시뮬레이션 모형에 통합될 수 있도록 개발된 운행모드 기반 배출량 산정모형이다. 본 연구에서는 한국의 차종, 주행특성, 배출계수, 배출규제등을 반영하여 MOVES Lite를 개량한 MOVES Lite-K를 개발하기 위한 연구를 수행하였고, 국내의 대표적 배출량 산정 방법인 평균속도 기반의 배출계수 곡선식과 MOVES Lite-K의 배출량 산정 특성을 비교하여 두 방법론의 차이와 국내 적용성을 살펴보았다.
