현재 기존 철송 시스템에 있어서 문제점인 출발지와 목적지 사이 발생하는 복잡한 작업 프로세스(job process)를 간소화하여 철송 운임비감소와 물류운송의 체계 개선 및 활성화에 기여할 수 있는 시스템으로 DMT(Dual Mode Trailer) 시스템을 들 수 있다. 이에 본 기술의 국내적용 및 개발을 위해 기술동향 조사 및 국내 적용시 고려사항, 국내 적용 접합 모델 도출 등 기술성을 분석하였다.

In light of the growing traffic congestion problem and congestion cost, the container transport by railway has to be increased. The freight transport by railway can have decided advantages over trucks in terms of energy efficiency, emissions and cost for certain freight movements, just as transportation in the metropolitan region can have great advantages over driving truck. But the freight transport by truck should gain significant mobility benefits from a freight railway system. Thus, the DMT(Dual Mode Trailer) transport system which is coupled railway transport advantages with load transport advantages has been developed and used in the european countries. The DMT transport will therefore serve the areas required by transport organizers. The purpose of this paper is to estimate economical feasibility analysis for development of DMT transport system. Consequently, this study analyzed the characteristics of the DMT system. The horizontal load.unload system is being considered as an adoptable DMT system in consideration of the situation in Korea.

국가 물류 수송의 총 사회적 비용을 감소시키기 위해 기존의 물류 수송 체계를 철도 중심의 물류체계로 전환해야 할 필요성이 있다. 이를 위해 DMT와 같은 다양한 새로운 운송 수단의 도입이 고려되고 있으며, 이러한 운송수단의 도입은 기존의 도로의 수송 분담률을 낮춰줄 것으로 기대된다. 그러나 새로운 운송 수단의 도입에 따른 경제성 평가는 대부분 화물 운송 소비자의 효용함수를 도출하고, 이 효용함수로부터 수단별 운송 분담률이 어느 정도 될 것인지를 추측하는 데에 치중해왔다. 본 연구는 운송 소비자의 효용과 사회적 비용을 동시에 고려하여, 물류수송에 관여되는 사회적 비용을 최소화하는 적정 수송분담률을 구하기 위한 수리 모형을 제시하고자 한다. 이를 이용하여 컨테이너 화물에 대한 운송 수단별 적정 수송 분담률을 계산해 본다.

Many advanced nations have been developing the next generation logistic systems to effectively deal with gradually increased logistic flows over the world. Particularly, dual mode trailer(DMT) systems are significantly focused as a new alternative transportation which basically provides integrating of the land and railroad services. This paper presents new driving mechanism for DMT systems using the hydraulic pressure cylinder systems. Such is mechanically composed of supporting and rotating parts independently, which are mostly important for whole system performance. We analyze feasible operational problem occurred in driving mechanism from the conventional DMT systems and compare our proposed deign specification with the Modalohr DMT system to demonstrate its reliability and practicability.
