Along with container freights keep increasing globally, lots of containers used for inland distribution increase steadily too. In Korea, there are many modes to transfer container freights such as roadway, railroad, coastal shipment. The roadway transportation is the most common but it is considered as the most inefficient mode. This paper studies about reasons that affect to the inefficiency of roadway transport and finds solution to resolve the problem. First backhaul transportation is addressed and some suggested solutions are presented such as construction of inland inspection center or managing efficiently container management. Then mathematical model is used to show the quantitative evaluation of backhaul transport solution.

본(本) 연구(硏究)에서는 우리나라 화물자동차운송산업(貨物自動車運送産業)에 대한 각종 정부규제(政府規制)의 문제점(問題點)과 개선방안(改善方案)을 제시하였다. 주요 개선방안으로서는 사업구성제한(事業區城制限)의 폐지(廢止), 사업공탁금제도(事業供託金制度)의 도입(導入)을 통한 면허제도(免許制度)의 개선(改善), 톤급에 의한 업종구분(業種區分)의 폐지(廢止) 등을 제시하였다. 종합적으로 고찰해 볼 때, 현재의 업계관항(業界慣行)은 이미 높은 경쟁상태에 도달하여 있으며, 정부의 비현실적인 규제가 오히려 건전한 경쟁질서(競爭秩序)의 확립에 장애(障碍)가 되고 있다고 할 수 있다. 따라서, 정부규제(政府規制)가 현실의 시장상황(市場狀況)과 사업자들의 합리적(合理的) 사업욕구(事業欲求)를 따라가지 못하고 있다고 말할 수 있으며, 화물자동차운송산업(貨物自動車運送産業)에 있어서의 정부규제개선(政府規制改善)이란 정부규제(政府規制)의 현실화(現實化)로 표현할 수 있을 것이다. 또한, 지입제(持?制)의 억제(抑制), 직관기업화(直管企業化)의 추진(推進)등의 정책목표(政策目標)의 타당성(妥當性)과 정책수단(政策手段)의 실효성(實效性)에 대한 근본적인 재검토가 필요하다고 하겠다.

Recently, the Supreme Court of Korea delivered a milestone judgment about air related multimodal transport. At there, the mattered cargo, some expensive jewellery, was transported from Qingdao, China to downtown office of consignee at Seoul via Incheon airport in Korea. As an air waybill was issued in this case, there was an air transport agreement between consignor and air courier operator. After arriving at Incheon airport, the shipment was transport by land arranged by the air courier operator, who was a defendant in this case. Upon arriving at the final destination, it was found that the jewellery was lost partly and based on circumstantial evidence, the damage presumed to be occurred during the land transport. As a subrogee, the insurance company who paid for consignee filed an action against the air courier operator for damage compensation. Defendant contended that Montreal convention should be applicable in this case mainly for limited liability. The lower court of this case confirmed that applying the limited liability clause under Montreal Convention is improper under the reason that the damage in this case was or presumed to be occurred during surface transport. It was focused on the Montreal Convention article 18 which says that the period of the carriage by air does not extend to any carriage by land, by sea or by inland waterway performed outside an airport. However, the Supreme Court overturned the lower court's decision. The delivered opinion is that the terms of condition on the air waybill including limited liability clause should be prevailed in this case. It seems that the final judgment was considered the fact that the only contract made in this case was about air transport. This article is for analysis the above decisions from the perspective that it is distinguishable between a pure multimodal transport and an expanded air transport. The main idea of this article is that under the expanded air transport, any carriage by land, sea or inland waterway only for the performance of a contract for carriage by air, for the purpose of loading, delivery or transhipment is still within the scop of air transport.

Recently, the government of Russia has been cooperating with developed countries such as Germany, which have an advanced railroad system. They have been establishing a strategy to activate the Siberia Trans Railway. Thus, it is possible that a part of cargo will be transported by TSR (Trans Siberia Railway) instead of shipping. If there is a railroad system, connecting the North and the South Korea via the Busan port, a new freight route linking to Europe will be reached. This paper aim to investigate the intention of shipping companies, shipper, forwarders, who are prospective customers and/or competitors of TSR. An analysis of the competitiveness between TSR system and the waterway transportation will be also mentioned.

Interest and demand in heavy cargo logistics is increasing and becoming more diverse as economic scales have expanded and manufacturing activity has increased. Although cargo moves via maritime and/or land transportation, there is currently insufficient research on the actual condition of heavy cargo logistics. The purpose of this study is to carry out an in-depth analysis of heavy cargo laws, systems, logistics patterns, and current transportation status. By proposing measures to solve existing problems, this study aims to make an important and ongoing contribution to the scarcely studied field of heavy cargo logistics. The result of regression analysis on the main seven factors show that transportation frequency and law/system structure have a positive effect on working conditions. Furthermore, the result of correlation analysis on the main seven factors show that the cargo weight variable is highly positively correlated with cargo size. Also, the working conditions variable is highly positively correlated with the law/system structure. Detailed proposal measures to solve existing problems are summarized as follows. First, it is necessary to establish a clear concept of heavy cargo as numerous existing definitions differ. Second, laws and provisions relating to maritime and land transportation of heavy cargo need to be established and consolidated as current applicable legislation is insufficient. Third, the classification system for heavy cargo transportation needs improvement. Fourth, it is necessary to improve transportation performance statistics and the aggregate criteria system. Finally, the management system of heavy cargo also needs improvement.

Rail transport has been considered an environmental-friendly transport mode compared with other transport modes such as ship, truck, and aircraft. However, air pollutions emitted by diesel locomotives have emerged as social issues. In addition, the railway industry may not be able to avoid a duty of alleviating greenhouse gases emission owing to the Korean government policies for green growth which is an economic paradigm that simultaneously pursues growth and environmental improvement. Moreover, rising oil prices has burdened a train operating company. The purpose of this paper is to develop a methodology of determining an economical speed of diesel freight locomotive from the viewpoint of the train operating company. In the methodology, we first define an operational cost function based on various cost factors and then suggest formula to calculate an economical speed of diesel freight locomotive. To estimate the influence of cost factors such as diesel price, carbon taxes, and time costs on the speed of diesel freight locomotive, sensitivity analysis was conducted.

Currently, urban areas face congestion problems that diminish personal mobility and freight-transport productivity. An increasing number of experts suggest that separating freight traffic from passenger traffic makes sense in terms of economics, the environment, and safety. Some experts suggest that tube transportation is the solution. The objective of this paper is to evaluate the potential benefits and limitations of tube transportation system as a viable mode of transport that can alleviate congestion on roadways. Specifically, this research employs theoretical and practical method identifying, evaluating, and selecting appropriate freight pipeline systems; evaluating the technical and economic feasibility of tube transportation; and estimating environmental, energy, and safety benefits.

The improvement in logistics competitiveness is the key element of corporate competitiveness in the era of severe competition among companies and high oil prices due to globalization. For this reason, this study analyzed the effect of transportation mode selection factors of Indonesian export companies on the logistic performance in accordance with the logistics environment. The results of the analysis show that only the cargo characteristics, which are the transportation mode selection factor of export companies, had a significant effect on logistics; the services, time, and expenses, on the other hand, had no effect on logistics performances. This result reflects the poor logistic infrastructure of Indonesia. While the export company considers service, time, and expenses when choosing transportation mode, it had no effect on logistic performances due to poor logistic infrastructure. The poor logistic infrastructure of Indonesia has caused a rise in the overall logistic expenses of companies due to excessive transportation time over the transportation distance, unavailability of on-time acceptance and delivery, and increase in the transportation expenses and subsidiary expenses. These are also the factors that decrease the competitiveness of export companies and affect the promotion of the manufacturing industry and foreign investment for the purpose of job creation and industrialization by the Indonesian government. Therefore, the logistics infrastructure must be improved initially. This study determines various points in terms of the logistics infrastructure environment of Indonesia, a developing country, using previous studies and provides their implications.
