초록
화물차량의 통행패턴은 여객통행에 비해 연구 성과의 누적이 상대적으로 적은 분야이다. 그럼에도 불구하고 도시 내통행에서 화물차가 차지하는 중요성에 대한 인식이 증가하고 있으며, 자가용 화물 차주들의 능동적 사업 비율이 증가하고있어 이 분야에 대한 더 많은 연구의 필요성이 대두된다. 본 연구는, 여객통행에서의 활동기반 수요추정 이론의 발달에 부합하는 화물통행에서의 의사결정 원리에 대한 연구의 기초로서, 화물차량 통행실태 조사의 자료를 분석하여 화물차량 톤급별 평균 통행 특성, 운행효율성, 도착지-도착지유형-적재품목 통행연쇄의 특성을 확인하였다. 분석 결과 이들 화물차량 통행 특성들은 톤급별로 분명한 차이가 있음을 확인하였으며, 그 자체 화물차의 톤급별 특징을 잘 보여주었다. 연구 결과는화물차량 통행 관련 교통정책 수단 개발에 긍정적 기여를 할 수 있을 것으로 기대된다.
Abstract
Freight travel pattern has been less studied comparing with the field of passenger travel. Nonetheless, the importance of the freight travel has been increasing in urban travel sector, and the research needs on the freight travel demand hence is increasing. The current paper aims to identify,by tons of freight trucks and cargos, the characteristics of mean travel pattern, efficiency or performance, and the characteristics of freight trip chain regarding destination location, destination type and freight type. The study analyzed the nation-wide data of freight travel behavior survey. This study intended to set the starting framework of decision-making principle in freight travel,which has already been popular in passenger travel study. Findings suggest that those characteristics are clearly distinguished among trucks and cargos of different sizes of tons. The results are expected to provide important insight to the development of relevant transportation policy measures.
