Abstract

Global warming, mainly caused by CO2, is one of the on­going cataclysms of the human race. The nation­wide policy to reduce greenhouse gases (GHG) has been enforced, for which it is crucial to estimate reliable GHG emissions. The unit load of road­section CO2 emission (URSCE) is a prerequisite for the evaluation of GHG emissions from road mobile source, and it is mainly computed using vehicular velocity source. Unfortunately, there is real­world limitations to collect and analyse representative speed data for nation­wide road network. To tackle this problem, a method for the evaluation of URSCE, proposed in this study, is based on a disaggregated way using big GPS vehicle data. The method yields more accurate URSCE than an current aggregated data based approach and can be directly employed for nation­wide road systems.

지구 온난화는 인류의 재앙이며, 그 주된 원인은 이산화탄소이다. 따라서 온실가스 저감을 위한 범국가적 정책이 수행되고 있으며, 정책의 수립/집행에 있어 정확한 온실가스 배출량 산정은 매우 주요하다. 도로이동오염원에 의한 온실가스 배출량 산정을 위해서는 도로구간별 CO2 배출 원단위가 필요하며, 이는 차량의 속도자료를 이용하여 산정된다. 그러나 전국 도로망에 대한 속도자료의 수집 및 분석에는 한계가 있다. 따라서 본 연구에서는 방대한 양의 차량 내비게이션 자료를 이용한 비집계방식의 도로구간 CO2 배출량 원단위 산정방법을 제시한다. 제시된 방법론은 기존 집계방식에 의한 CO2 배출 원단위보다 정확하며, 전국 도로망에 직접적으로 적용이 가능하다.
