As the lack of management for HAZMAT transportation leads to fatal accidents, the interest in the problem is rapidly increasing in the world. Thus UN-RTDG recommends to establish regulations for HAZMAT transportation, and related ministries in Korea make rules and policies according to the regulations. However, there are few researches carried out on railway HAZMAT transportation. In this paper, issues such as present condition of laws and policies related to railway HAZMAT transportation, HAZMAT transportation procedure and regulations, HAZMAT signs of railway etc. are analyzed. Through analyzing these issues the problems and improvements of railway HAZMAT transportation are drawn. These results are respected to help to establish regulations and policies for HAZMAT transportation management. In the future, more detailed plan is needed for putting these improvements to practices.

This study is to develop the model of alignment optimization based on design criteria by approaching through alignment of railway design and problems in economy, environment and technology for satisfying traffic volume of the main roads caused by economical and social developments. Now, Geographic Information System isn't applied when designing a present railway in home. And the design of railway alignment is still set on importance of transition curves and cant according to passenger comfort in abroad so tile study of railway alignment is at initiation phase so far. This paper is about decision of optimal alignment between two stations such as starting point and ending point automatically using GIS in optimization of railway alignment. A route between Sungsan city and Shinpung city is the training area and the study compared and evaluated optimal railway route by GIS automatically with present railway route designed. Present optimal fomulas was used in this study for optimization of railway alignment. The model of optimization of railway alignment was developed through topographical elements and it was mentioned by the model of road alignment because of the similarity in design of alignment. But the design of lateral track irregularities, cant fur passenger comfort and motion sickness fellowed by train rolling have to be considered more. Anyway, this study farmed the basis of using GIS and the study should be keep going on in the future.

현재 운영되고 있는 광역도시철도 시스템에서는 표정속도의 저하에 따라 평균 출퇴근 시간도 계속 증가하고 있으며 이는 도시철도 이용률의 저하와 타 교통수단 대비 졍쟁력 저하로 이어지게 된다. 따라서 열차의 표정속도를 대폭 향상시킬 수 있는 광역도시철도의 효율적인 급행화 방안이 요구되고 있다. 이번 연구에서는 가감속도와 최고속도 성능을 향상시킨 고성능 전동차 투입을 고려하여 급행과 완행으로 분리 투입시 획득 할 수 있는 시간 단축 효과와 경제성을 기준으로, 광역철도간 급행화 방안들을 제안 및 그 결과를 비교 분석하였다. 또한 대피선 설치를 최소화 할 수 있는 최적의 급행화 방안을 분석결과로 제안하였다.

유동인구 자료는 도시의 동적 활동을 파악하는 지표로서, 도시철도 등 교통 분야에서 장기적 측면의 계획 수립에 유용한 자료로 활용 가치가 높다. 하지만 현재 유동인구 자료는 현장 조사 및 이동통신 자료에 기반한 사후 수집 방식으로, 장래 계획 수립에 활용성이 낮은 실정이다. 이에 본 연구에서는 유동인구에 영향을 미치는 다양한 요인들에 대한 분석을 통해 향후 유동인구 예측을 위한 기초를 마련하였다. 이를 위해 2013년 12월에 수집된 서울시 6개 구(강남구, 서초구, 송파구, 영등포구, 종로구, 중구)의 유동인구 자료를 활용하여 음이항 회귀모형을 구축하였으며, 모형 구축 결과, 세대수, 종사자수, 지하철 역사수 및 버스 노선수 변수가 유동인구 예측에 통계적으로 유의성을 가지는 것으로 나타났다. 이처럼 유동인구에 영향을 미치는 요인에 대한 분석을 통해 향후 도시철도 등 교통 분야의 장기적 계획 수립에 해당 자료의 활용성을 높일 수 있을 것으로 판단된다.

The first high speed railway in Korea was opened to traffic on April 1, 2004 and the second phase will be opened on November 1. 2010. Many technical problems that occurred during construction have been solved. In its early period of project, difficulties were encountered in design, construction of high speed line. because most of Korean railway engineers were familiar only with conventional railway. Now they understand the various phenomena occuring during operation of the KTX and have accumulated extensive technical knowhow. Valuable experiences and knowledges that have been obtained from frials and errors will lead to further improvement for the future project.

TTX(Tilting Train Express), which has improved traveling performance on curved track, is being designed in cope with future railway circumstance. Nowadays, in the world, many efforts are focussed on railway safety. Especially, a variety of researches on train crashworthiness have been conducted. As a part of these efforts, some equipments on TTX are designed to reduce fatalities and casualties in crash accidents. This paper introduces impact energy absorbtion characteristics on the initial design of the front end structure. Some comments are made briefly for improvement of initial structural design and future following researches.

Studied was a strategic plan for the Korean High-Speed Train system to penetrate the Chinese railway market in exchange of the technology of KHST. Firstly, taken was a glance at Chinese Government plans to extend total length of his railway lines and to construct the Beijing~Shanghai high-speed railway line. Then, disparity of railway technology in Korea and China was reviewed. From the review, SWOT Analysis were carried out to penetrate the foreign markets. Countermeasures to cope with SWOT were also considered. Strategical governmental supports and the establishment of the special organization to be in charge of penetration of KHST into foreign markets were proposed. Finally, also proposed was the transfer of KHST technology to Chinese counterparts in exchange of tangible benefits for Korean side. The benefits may include (1) adoption of KHST as the type of rolling stock for the Beijing~Shanghai line, (2) guarantee of participation in the project and royalty for the KHST technology used for the future high-speed railway line construction, (3) prior written approval and partnership when making its way to third country, and (4) participation of Korean construction companies in Chinese railway construction project, etc. Adoption of KHST in China indeed gives chance to integrate the high-speed railway network after reunification of Korean peninsular, and enhance the economic ties between two countries.

TSI(Technical Specification for Interoperability) is the highest technical specification in the Europe Railway and is composed by assessment items and essential requirements included by safety, reliability, availability, health, environment protection and technical compatibility. It is used on the research and development in the next generation railway technical. Currently, TSI procedures have been asked to bid for high speed rail business in Europe and Brazil. Also, all the railway systems such as infrastructure, signaling, electric and rolling stock system corresponding with standard of TSI procedures are exported and imported. Recently, Safety Critical System which has been studied on future railway R&D business in Korea is the state of the art train control system. And it is needed for system assessment of TSI procedures before system test and operation. In this paper, basic research is performed for analyzing TSI procedures suitable for the state of the art train control system in Korean railway.

The purpose of this thesis is to know and understand the user requirements to provide with intelligent railway information service in response to the Ubiquitous environment. The railroad specially has a disadvantage of door-to-door service, however by using the information and communication techniques, we can provide the passengers who are using the intermodal transportation means with the realtime information, therefore we can overcome the above disadvantage. To deduce the passenger's needs for providing the future-type railway information service, we introduce the results of the questionnaire. In chapter 2, we studies on the concepts of intelligent railway information service, and in chapter 3, we investigate the cases of Japan and China, and in chapter 4, we study the passager's satisfaction by the questionnaire concerning the railway information service and suggest the needs for information offering.

In order to promote economic cooperation and future reunification in Korean peninsula, this study is conducted to initiate a reconnecting plan for north and south Korean railways. When practical works to interconnect two counties' railway systems begin, the differences of railway systems such as rail track, railway facilities, communication systems, electrical power systems would be emerged as barrier. In this paper, to solve this problems, plan for the secure system-operational technology is presented. It also could be used for shaping the national transport network and constructing railway operating systems.
