This paper presents a network capacity model that can be used as an analytical tool for strategic planning and resource allocation for multimodal transportation systems. In the context of freight transportation, the multimodal network capacity problem (MNCP) is formulated as a mathematical model of nonlinear bi-level optimization problem. Given network configuration and freight demand for multiple origin-destination pairs, the MNCP model is designed to determine the maximum flow that the network can accommodate. To solve the MNCP, a heuristic solution algorithm is developed on the basis of a linear approximation method. A hypothetical exercise shows that the MNCP model and solution algorithm can be successfully implemented and applied to not only estimate the capacity of multimodal network, but also to identify the capacity gaps over all individual facilities in the network, including intermodal facilities. Transportation agencies and planners would benefit from the MNCP model in identifying investment priorities and thus developing sustainable transportation systems in a manner that considers all feasible modes as well as low-cost capacity improvements.

Purpose - This study is a study to investigate the problem of the selection of means of transportation in international logistics by studying the basics of logistics activities, selection factors of transportation methods, and multimodal transportation. Research design, data, methodology - This study is composed of 5 chapters through literature study. Chapter 1 describes the functions and transportation system of international logistics, Chapter 2 selects transportation, Chapter 3 deals with maritime transportation and multimodal transportation, Chapter 4 describes multimodal transportation in terms of customer service, Chapter 5 addresses the implications and conclusions. Results - When looking at the problem of selecting a means of transportation, it is important that the parties involved in the transportation choose which means of transportation for their convenience and profit during the transportation process. Here, there will be factors to consider, including transportation cost, when selecting a means of transportation, and each means of transportation may have characteristics or advantages and disadvantages. Considering all these points, the adoption of multimodal transportation from a customer service point of view may be the answer. Conclusions - This study pays attention to the academic understanding related to the selection of means of transportation and to how usefully this thesis can be used in the selection of transportation related persons, especially shippers, from a practical level.

The purpose of this paper is to introduce the limitation of liabilities of multimodal transport operators(MTO) in Korea. Also, this paper reviews the revised draft of Korean Commercial Code in 2015. This paper analyzes Korean multimodal transport systemand the limitation of liabilities of MTO by analyzing articles, regulations and practices of Korean Commercial Code and it's the draft in 2015. The paper, also, studies multimodal transport rules by comparing specifically international treaty, rules, or practices. In Korea, Article 816 of Commercial Code treats multimodal transportation adopting the network liability regime. The Article describes only the case of the multimodal transportation where the maritime carriage is engaged. Korea proposed the draft of multimodal transport regulation of Commercial Code in 2015 because present law could not apply for the multimodal transportation involved in the air or land carriage. This paper support the draft of Korean Commercial Code in 2015 because it is necessary to make a predictable legal system of multimodal transport and the limitation of liability reflecting practices or customs.

This paper reviews search methods of multiple reasonable paths to implement multimodal public transportation network of Seoul. Such a large scale multimodal public transportation network as Seoul, the computation time of path finding algorithm is a key and the result of path should reflect route choice behavior of public transportation passengers. Search method of alternative path is divided by removing path method and deviation path method. It analyzes previous researches based on the complexity of algorithm for large-scale network. Applying path finding algorithm in public transportation network, transfer and loop constraints must be included to be able to reflect real behavior. It constructs the generalized cost function based on the smart card data to reflect travel behavior of public transportation. To validate the availability of algorithm, experiments conducted with Seoul metropolitan public multimodal transportation network consisted with 22,109 nodes and 215,859 links by using the deviation path method, suitable for large-scale network.

Recently, there has been an increase in interest from the aspects of transshipment and connection between the means of transportation. Not only for passengers but also for freight transportation as the need for transportation efficiency is growing while the importance of logistic railway transportation is emerging. The domestic freight transportation is carried out by roads, railroads, ships, and port. However, as other means of transportation, except road, is impossible for Door to Door Service, multimodal transportation accompanied by road transportation is carried out. Here, even though 'transshipment' occurs, because of the lack of basic data regarding this, it is difficult to reflect it in the demand forecasting. With respect to the Korean freight O-D, it was very difficult to have equivalent comparison on the competitiveness and availability of transportation services between the point of departure and the final destination. Taking into account the study of implementation of logit model considering the time and cost of transshipment of multimodal transportation and the transshipment resistance value upon selecting means of freight transportation on multimodal transportation was comparatively insufficient. This study consisted of questionnaire targeting shippers, and based on this, transshipment resistance value was calculated by deriving utility function. By doing so, I intend to examine the effect 'transshipment' has on selecting the means of transportation occurring from freight transportation.

The transport a administration in Korea is meeting demands of developing international multimodal transport system. In the past, as Korea transport policy has been emphasizing on the passenger traffic, the physical distribution sector is far behind international trend. Regarding the urging necessities of reducting costs in transport in order to upgrade the competitive edge of industries, Korea has to develop the most efficient transport system so called international multimodal transport system. The existing transport system is inefficient because each transport mode is separate, so this system is aiming at reducing cost and time and developing freight transport. The scope and scheme of this thesis should be as following. Chapter 2.

도시의 교통문제 증가로 대중교통의 중요성과 역할에 대한 인식이 높아져가고 있다. 이러한 패러다임의 변화에 반해 기존 대중교통 통행배정과 관련한 연구는 여러 측면에서 한계가 있다. 복합대중교통망의 경우, 독립수단으로 이루어지는 도로교통과는 달리 수단간 환승, 운행시간 스케줄, 대기시간, 통행요금과 같은 복잡하고 다양한 특성을 포함하기 때문에 그 분석의 어려움은 배가 될 수밖에 없다. 특히, 수도권 대중교통 통합 환승할인제의 시행에 따른 대중교통 수단간 환승통행의 증가와 이에 따른 경로선택의 변화로 대중교통의 통행행태가 변하고 있으나, 기존의 대중교통교통망 구축방법으로는 이러한 변화를 반영하기에는 한계가 있다. 최근 첨단기술의 발달에 따라 대중교통이용자의 통행정보가 실시간으로 기록되는 첨단교통카드체계가 구축 운영 중에 있다. 이러한 첨단기술의 도입은 복합대중교통망 분석에 대한 새로운 접근방법에 대한 연구를 가능하게 하였다. 이에 본 연구에서는 교통카드자료의 통행정보를 효과적으로 활용할 수 있는 대중교통망을 구축하기 위해 정류장의 위치정보와 노선정보를 활용해서 새로운 복합대중교통망을 구축하는 방안을 다음과 같이 제시하였다. 첫째, 교통카드자료의 통행정보를 활용하기 위하여 정류장 기반의 통합교통망을 구축하는 방안을 제시하였다. 둘째, 컴퓨터 기반의 프로그래밍기법을 활용한 단절된 링크의 연결방안을 통해 대중교통의 환승문제를 해결하고자 하였다. 마지막으로, 복합대중교통망의 경로탐색에 있어 가장 큰 문제가 되는 다수단간의 경로탐색에 대한 방안을 제시하였다. 본 연구에서 제시한 방안으로 복합교통망을 구축할 경우, 기존 정류장 좌표와 대중교통의 노선정보를 그대로 활용하여 교통망을 구축할 수 있어 교통망 구축이 쉬울 뿐만 아니라, 환승링크 연결과 같은 별도의 교통망 작업 없이도 대규모 교통망에서의 활용이 가능해 진다.
