Abstract

Light-duty trucks are a major means of transporting domestic short-haul road freight, and the importance of light-duty trucks is expected to increase with the expansion of electronic commerce. However, light-duty trucks are perceived as the main cause of fine dust in the city center due to vehicle deterioration, frequent driving and idling. This study aims to derive the technical factors and alternatives (electric, hybrid and DPF-equipped trucks) to convert light-duty trucks into eco-friendly trucks through an expert survey. To this end, the relative importance of the retrofit technology was evaluated using the analytic hierarchy process method. Results confirmed that the retrofit and maintenance costs should be considered as the first priority when evaluating alternative truck technology. In addition, the government needs to reduce the economic burden of truck owners through various subsidies to convert light-duty trucks into eco-friendly trucks. We hope that the results of this study can be used as a basic evaluation index in the development of eco-friendly truck conversion technology and design of policy for converting old trucks.

소형 경유 트럭은 국내에서 발생하는 단거리 도로 화물을 운송하는 주요 수송 수단으로, 전자상거래의 발달로 그 중요성은 더욱 증가할 전망이다. 하지만 소형 경유 트럭은 노후화, 잦은 주정차 및 공회전 증가 등으로 도심 미세먼지의 주범으로 인식되고 있다. 이에 본 연구는 전문가 설문조사를 통해 소형 경유 트럭을 친환경 트럭으로 개조시키기 위한 기술요소 및 대안(전기트럭, 하이브리드트럭, DPF 장착 트럭)을 도출하였으며, 요인들에 대한 상대적 중요도를 계층분석법(AHP)을 활용하여 평가하였다. 분석 결과, 친환경 트럭 기술 대안들을 평가할 때 개조비용 및 유지보수 비용을 가장 우선적으로 검토해야 하는 것으로 나타났다. 또한, 정부는 소형 경유 트럭을 친환경 트럭으로 개조 시 다양한 지원 정책을 통해 차주들의 경제적 부담을 경감시킬 필요가 있는 것으로 조사되었다. 소형 경유 트럭을 친환경 트럭으로 개조함에 있어 고려되어야 할 주요 요인들을 도출하고, 요인들 간의 상대적 중요도를 파악하여 최적의 기술 대안을 제시한 본 연구의 결과가 친환경 트럭 개조 기술 개발 및 노후트럭 지원 정책 설계 시 기초 평가 지표로 활용될 수 있기를 기대한다.
