The goal of this study is to quantitatively evaluate the effects of the additional construction of urban railroads. To this end, 1) establish accessibility as a measure of quantitative evaluation of construction effects; 2) select the 'Integration' of Space Syntax as a quantifiable indicator of accessibility; 3) represent the Seoul railroads as a network; 4) calculate the 'Integration' form the network before and after the additional construction of the urban railroads. By calculating the change of the 'Integration' of the individual nodes and the change of the sum of the 'Integration' of given zones, the change in accessibility of a particular node and the change in accessibility of a particular region were calculated. After analyzing the change in accessibility in nodes and areas as well, it was confirmed that the additional construction of urban railroads was improving accessibility as a whole of Seoul. It was also identified that there was a degree of difference in the extent of the accessibility change for the different areas. It is particularly noteworthy that changes occur in the accessibility ranking. While certain regions were improving relative rankings, others fell in rank. With this finding, it could be argued that active consideration of the areas in which the relative decline occurs is needed when the planned urban railroad is being built.

Considering the situation in the early 20th century when the existing urban system centered on urban areas began to change, the biggest factors causing urban structural changes in urban areas are construction of railroad and urban dismantling. The change process of Eupseong, in the microscopic viewpoint, can be understood as a process of change in the course of dismantlement of town's demarcation, improvement of accessibility and urban expansion due to the construction of railroads, process of urban expansion following the crumbling boundaries and structural changes. This study aimed to look at the transformation process of the Eupseong in the early 20th century, focusing on the demolition of the castle and the railway construction from a microscopic point of view of city.

In spite of numerous advantages in railroads such as mass transportation, high reliability, and environmental soundness etc., the value of railroad construction is relatively underestimated compared to road. This is because the current method of evaluation focuses mainly on economic effect. In this study, considering recent research results, the environmental value of railroad construction was assessed by calculating the effect of reduction of emissions and water contamination. With these two benefits, the environmental effect produced by railroads and road construction was calculated and compared to each other using EMME/3. As a result, the senario 4 which considers 'Hot/Cold start' condition and water contamination had highest benefits. Furthermore, the environmental effect produced by railroad is 55~101% higher than road construction. If the suggested method is used in the current appraisal system, the environment-friendly mode like railway would be highly valued, much more than before.

For the construction of railroads in Metropolytan area based upon the outcome of the future demand forecast, a total of 21 lines including electrified double track segment of Ui-Jung-Bu↔Dong-Du-Chun(18.9km) in Kyung-Won Line is expected. Considering the financial difficulties and investment effect of the lines, this in the sequel brings about an important matter of deforming priority Investment plan to build electrified lines among the candidates. In the case of Japan, Tokyo metropolytan area covered In total by 2,070.1km of various lines, i.e., subway lines(241km), private lines(952.7km), JR lines(876.4km), provides convenient means of transportation for the coummuters and makes a contribution to the development of its neighboring areas and to the expansion of settlement areas. Comparing the total length per 1,000$\textrm{km}^2$, Tokyo(105), Paris(117), and London(115) are at least 6 times as large as ours(15). The purpose of this study is two fold provide a basic scheme for building railroads in metropolytan area and determine priority order in accordance with some evaluation criteria.

The Incheon International Amort Railroad (IIAR) is the railroad that connects Incheon International Airport, Gimpo Airport and Seoul Station. IIAR is now under construction, and it will be finished to Gimpo Amort by 2006, to Seoul Station by 2008. But IIAR is not only so late to start but also has no discussion about effective connecting methods to existing railroads and fine operation plan. Therefore, after IIAR opens, it is possible for IIAR to lose to limousine bus using highway. So, this paper proposes 4 effective connecting methods for IIAR - (1) Shuttle transport, (2) Short-distance connecting transport (Inside IIAR, Seoul Subway Line 9, 'Han-River line') (3) Mid-distance connecting transport (Jung-ang, Tae-baek, Young-dong line) (4) Long-distance connecting transport (Korean Train express (korean high speed railroad)) These methods can increase the connectivity of IIAR with existing railroads and the competition power of IIAR against highway.

Transportation routes by land like a human being blood vessel should exist for economic and trade exchange in Northeast Asia. Thinking from this point of view. I believe that TSR(Trans Siberian Railroad) and TCR(Trans Chinese Railroad). which will be connected with I would like to talk about .not only the effects of various international railroads and their connections but also economic activation TKR(Trans Korean Railroad). can play important roles. In this study, and effects in Northeast Asia which will be resulted from various international railroads construction. I tried to figure out comparative superiority and comparative advantage of the trade structure and industries in South and North Korea to find out the possibility of economic unification in East Asia. especial1y in Northeast Asia. This study also includes the effort to find out how trade exchange between South and North Korea can be expanded as a result of being a member of East Asia economic zone.

Purpose - Given the increasing interest in the Eurasian Initiative, government-wide studies for the construction of the Silk Road Express are currently being conducted. However, the Korean Government has no experience in operating international freight railroads and has not encountered problems in train service plans, international conventions, and customs clearance, which will arise when TKR is connected to TSR, TCR, and TMGR. Research design, data and methodology - Given these conditions, the cases of direct services in international freight railroads between China and Europe are investigated to identify the possible problems in the connection between TKR and continental railroads. This study also identifies the plans for activating Eurasian railroad logistics. Results - For the service of international freight trains, Korea needs to join international conventions, such as OJSD, as a regular member. Furthermore, any relevant international conference after the conclusion of such an agreement is needed for the agreement on train service schedules, fees, and procedures for passing border stations. Conclusions - Customs clearance and relevant documents must be standardized to address the differences in clearance systems between nations.

중앙아시아 횡단철도는 가스피해 횡단철도, 카자린스크 철도, 투르케스탄-시베리아 철도, 카자흐스탄 횡단철도 등으로 구성된다. 중앙아시아 인구의 약 1/5에 해당하는 주민들이 이 철도를 중심으로 거주하고 있으며, 중앙아시아 경제의 70%정도가 이 횡단철도를 기반으로 하고 있다. 유라시아의 심장지역으로 간주되고 있는 중앙아시아 횡단철도의 건설은 해양세력과의 지정학적 경쟁, 변경지역과 중심지역간의 연계 강화 및 중앙아시아 경제의 특성화가 주 목적이었다. 구소련의 붕괴 이후 중앙아시아 각국의 모든 철로망이 주로 러시아와 연계를 맺고 있지만, 그 외 인근국가들과의 연계망이 미흡한 상태에 있다. 장기적으로 중앙아시아 횡단철도의 발전을 위해 해결해야 할 과제가 많지만, 그럼에도 불구하고 동서로는 동아시아와 유럽을, 그리고 남북으로는 러시아/발틱해와 인도양/페르시아만을 연결하는 대륙의 교량으로서의 역할은 여전히 유효하다.

2013년에 개발된 지능형 철도선형계획 프로그램(ei-Rail)은 주로 해외의 신규 철도건설사업 사전 기획 분석 및 설계 결과 검증 등에 활용되어왔다. 그러나 한국 철도산업의 해외 진출 대상국인 개발도상국에서는 대규모 비용이 소요되는 신규 철도건설사업 보다는 기존 철도의 선형개량을 통한 증속, 또는 단선철도의 복선화 등의 사업이 보다 필요하고 실행가능성이 높은 것으로 판단되며, 이런 유형의 사업수요가 지속적으로 발생하고 있다. 이에 본 연구에서는 기존의 신규 철도건설 사업 분석기능 중심의 ei-Rail 프로그램에 철도복선화 사업 분석기능을 추가하고자, 철도 복선화사업 모듈을 개발하였다. 기존에 운행 중인 철도 선형자료를 기반으로 복선화 사업의 종류와 규모를 반영하고 대상 지역별 공종 단가를 적용하여 공사비를 산출하고 설계도면 제작을 자동화할 수 있도록 하였다. 그리고 해외의 사례 적용을 통하여 ei-Rail의 복선화 사업 분석기능을 검증하였다. 향후 해외를 대상으로 하는 철도 복선화 사업의 기획 및 분석결과 검증을 보다 효율적으로 수행할 수 있을 것으로 기대한다.

Improvement is required to solve problems depending on long term use of signal equipment in the existing city railroad and to raise quality of passenger services. Accordingly, for more efficient improvement, we examined the procedure of executing construction of the communication based train control system in Korean city railroads, which is globally studied. The procedure of executing construction of the system is to present a plan for construction first of ail and then to prepare a strategy for construction of the system. It is required to establish a procedure for execution in each step depending on the prepared strategy and then to establish a detailed execution plan. We studied such an execution procedure, divided the execution procedure for application of the train control system through five steps to prepare the execution procedure.
