Abstract

Purpose: Greenhouse gases are one of the major causes of global warming, a global disaster. In this study, the priority that affects when calculating the GHG emissions in the road sector is accurately calculated based on the speed of individual vehicles from the existing section average speed. I have the purpose of finding a possible factor. Method: A comparative analysis is conducted between the conventional method of the general passage section, the rest area section, the entrance section, and the confluence section of the highway and the speed-based emission calculation method of individual vehicles. Result: As a result of analyzing a total of 6 sections of the Gyeongbu Expressway, it was found that the standard deviation of the speed and the congestion of the sections had a great influence. Conclusion: When comparing the existing GHG emission calculation method with the speed-based emission calculation method of individual vehicles, it is clear that the speed-based method of individual vehicles is more precise. However, since it is difficult to apply it all over the country, this study compares the existing method with the speed-based method of individual vehicles and presents factors that have a significant difference.

연구목적:온실가스는 전 세계적인 재난인 지구 온난화의 주요 원인 중 하나이다.본 연구에서는 도로부문 온실가스 배출량 산정을 기존의 구간평균속도에서 개별차량의 속도기반으로 정밀하게 산정할 때 영향을 주는 우선순위를 판별할 수 있는 요인을 찾아내는 목적을 가진다. 연구방법:고속도로의 일반 통행구간, 휴게소 구간, 진입구간, 합류부 구간의 기존 방법과 개별차량의 속도기반 배출량 산정 방법의 비교 분석을 진행한다. 연구결과:경부 고속도로의 총 6 구간에 대해 분석을 진행한 결과 속도의 표준편차와 구간의 혼잡이 큰 영향을 주는 결과가 나왔다. 결론: 기존의 온실가스 배출량 산정 방법과 개별차량의 속도기반 배출량 산정 방법을 비교하면 개별차량의 속도기반 방법이 더 정밀한 것은 확실하다. 하지만 이를 전국에 일괄 적용하기는 어렵기 때문에 본 연구에서는 기존 방법과 개별차량의 속도기반 방법을 비교하여 크게 차이가 나게 영향을 주는 요인을 제시한다.
