초록
군집주행이란, 운전자가 직접 운전하는 선두 차량과 차량 탑재 센서 및 V2V, V2I 통신을활용하여 선두 차량의 주행 경로를 따르는 한 대 이상의 추종 차량이 하나의 군집을 이루며주행하는 형태를 말한다. 그중 화물차 군집주행은 증가하는 화물량 및 교통물류 체계 첨단화수요에 맞추어 등장하였으며, 도입 시 도로 용량 증대, 인건비 절감, 연료 소비량 절감 등의효과가 있을 것으로 기대되고 있다. 그러나 일반 승용차에 비해 화물차의 자율주행 관련 연구및 효과에 대한 검증은 부족한 실정이다. 따라서 본 연구에서는 화물차 군집주행의 효과를 주제로 메타분석을 수행하여, 기존의 군집주행 효과 관련 연구 결과를 하나의 신뢰도 높고 일반화·객관화된 요약 추정치로 통합하였다. 결론적으로, 군집주행 도입 시 13.93%의 용량 증가, 38.76%의 상충 감소, 8.13%의 연료 소비량 감소 효과가 나타날 것으로 분석되었다.
Abstract
The platooning refers to a form in which one or more following vehicles along the path of the leading vehicle(directly driven by the driver) drive in one platoon using V2V, V2I communication and vehicle-mounted sensor. Platooning has emerged in line with the increasing demand for cargo volume and advanced transportation logistics systems, and is expected to have effects such as increasing capacity, reducing labor costs, and reducing fuel consumption. However, compared to general passenger cars, research on autonomous driving of trucks and verification of their effects are insufficient. Therefore, in this study, meta-analysis was conducted on the theme of the effect of truck platooning, and the results of existing studies related to platooning effects were integrated into one reliable, generalized, and objective summary estimate. In conclusion, it was analyzed that the introduction of truck platooning would have an effect of 13.93% increase in capacity, 38.76% decrease in conflict, and 8.13% decrease in fuel consumption.
