  • The government makes an effort to disperse the centralization of Seoul through the its surroundings development for relieving the various social problems caused by the capital region concentration. But, the planless development of rail system in the capital region have made it difficult to approach into Seoul city center from its surroundings. Through Seoul metro line 9, constructed by private company first in Korea, that has operation plan with normal and express train together, we would like to study up on promotion of passenger service quality such as "the improvement of the accessibility to Seoul city center from its surroundings" and "service of various pattern of trains"

  • Seoul Metro Line 9 (SML9) will link Gimpo Airport to the Gangnam district opening in May 2009. SML9 has a new model in Korea constructed by metropolitan government and private company and operated by specialized public transportation service provider. SML9 is confronted with tough environment of stagnated public transportation and strong competitor, Olympic city expressway. Consequently SML9 must lead the maximum efficiency by using its material and human resource. Hereupon, I propose renovation plans from 3 viewpoints of operation field of SML9: Rapid-Local combination, close connection with other transportation and direct connecting service into Incheon Air-port Railroad(AREX).

  • Over the years, the Social Republic of Vietnam has demonstrated its high annual growth rate over 8%. In order to secure its sustainable economic growth, its has also demonstrated its sharp concerns on building up core infrastructures by luring foreign investments on a large scale, which would underpin the nation's economic propulsion. Among others, transport infrastructures and networks centering on railway systems are obviously seen as the most urgent to be built to continue its growth. Seoul Metro recently took a significant step forward in Vietnam to launch railway business by executing its export project of 6 units of metro cars to Hanoi as on July 10, 2008. Those 6 cars are scheduled to be put on the tracks linking Yen Bian, Hanoi with Ha Long, for demonstrative running, around October, 2008, carrying tourists on that 163kms of the National Railway line serving the region. A successful running on the track will duly entail further export of additional 54 units of Seoul Metro cars to Vietnam. In this thesis, description will be noted on the reuse and economic value of the Seoul Metro's de-commissioned metro cars, reflecting on the current urban railway law at home regulating the service life of rolling stocks domestically. This thesis will also study the points at issue, and the recommendable future orientation of the Vietnam railway business project.

  • A new subway, line 9 linking Western and Eastern Seoul began its services for citizens between Gimpo airport and Gangnam area within 30 minutes by express transit service. Seoul Metro Line 9 Corporation plans to operate both local transit service which will stop at every station, and express transit service that will stop at several key stations including junctions. The passengers on line 9 will be able to transfer to lines 2, 3, 5, 8, Bundang and Incheon International Airport. The Line 9 is expected to disperse the demand for line 2, having the most number of subway users, and will provide passengers with less crowded travel. The new line will also help residents in southern Seoul outskirts and Gyeonggi provincial cities including Bundang vicinity, and Gangdong area commuters get better access to Gimpo and incheon Airports. The Corporation expects to transfer 560,000 passengers daily by the subway line 9. Seoul Development Institute conducted network reshuffle study for Seoul Metro system to sort out congestion problem due to its irrational line alignments and inconvenient transfer. Among several candidate plans of network reshuffling, the direct connection of line 9 with line 5 was chosen as a pilot study. The study found that direct connection of the 2 lines is essential for enhancing transit utility and reducing automobile commuters.

  • Preliminary feasibility study on Busan metro line #1 in Yangsan line (Nopo-Bukjeong) depending on active volume of mass transportation between Yangsan city and Busan city was conducted. As the study concluded that it's valid, the necessity to establish the metro railroad network connecting to Busan, Ulsan and Gyeongnam Province is demanded to improve the transportation issues in Ungsang area vulnerable to metro service and to drive the balanced development between metropolitan cities. In addition, the volume of transportation depending on methods in target areas and road traffic assignment are surveyed to put a stress on the necessity to establish the metro railroad network. As the demand of transportation for alternative lines is predicted, the budget and benefits for construction for each alternative line set for the rough economic analysis depending on traffic volume for each method and traffic assignment results. The total project budget necessary for construction of proposal line #1 set as effective one among target three lines in this project is calculated in 794.32 billion won. Construction accounts for the most expensive in expenses for project and contingency allowances, purchases for vehicles and collateral expense are followed in orders. However, compensation for lands is not counted. In particular, according to economic analysis in proposal #1, ratio of benefit/cost (B/C) is 0.584, net present value (NPV) is -217.47 billion won, the internal rate of return (IRR) is analyzed in 0.604 %. At the current stage, it is not economically feasible, but the B/C is 0.737 in long-term upon construction of Yangsan line between Wolpheong and Yongdang which is proposal line #3. Therefore, when Busan metro basic plan is reorganized to aim the benefit of residents in Ungsang area vulnerable to the metro service, we think it must be necessary to establish the metro railroad network connecting to Busan-Yangsan-Ulsan which is proposal line #2 by extending the existing Sinjeong line and including this task line in high-ranked plan related to metro railroad.

  • The inspection periods for the metro EMU maintenances vary variously according to the countries and railway operators. And the inspection systems vary according to the safety, economical, technical aspects, and also the social environments like passengers and maintenance qualities, etc. Also, in economic point of view, maintenance requires the man power, facilities, equipments, purchasing of parts and the loss of not being in revenue service during the maintenance period. Recently, there is a tendency that the inspection periods are extended gradually owing to the increased reliabilities of the equipments and parts of EMUs. Even if it is the EMUs that are already be in service, once the inspection method is innovated, the inspection time can be reduced. The inspection management innovation scheme includes such methods as the complete module to module replacement when trouble shooting a faulty parts before putting the EMU back to revenue service, the replacements of parts in complete set unit for the heavy maintenance, the establishments of exchange periods for the wasting parts, modernization of inspection equipments, introduction of RAMS for the reliability improvement and computerization of EMU maintenance management, etc. I think it is possible to optimize the inspection scopes and periods per parts and equipments by the introduction of RAMS.

  • While attention has been paid to 'core information poor' with low-level information literacy, public libraries are to be social agencies to set policies, and are to provide them with cultural experiences and services as well. In this regard, this study intends to shed light on the current status of public library services for such 'information-poor' as the urban poor, the handicapped, and the aged in Busan metro area. Exploring the statistical data, observations and interviews, the study attempts to illustrate current status and trends. It, specifically, focuses on the following characteristics of information service strategies: types of services provided; infra-structure including facilities and specialized collection; and, barriers and limitation of library and information use.
