Construction of metro transportation infra is a large-scale project requiring tremendous financial resources. This study suggests operation method to use for rapid transit line existing infra such as Gyeongbu line and spare line capacity following second phase KTX construction. Reviewing various constraints of metro rapid transit operation, we found that the conditions for metro rapid transit operation are already satisfied in Daegu area, just like the case of Gyeongbu line in Seoul Metro area. Also, the evaluation of the economic feasibility of metro rapid transit operation in Daegu area shows that B/C is about 2.4, which implies that there is sufficient economic feasibility. According to the result of sensitivity analysis, the project is economically feasible unless the passenger demand decreases 15% and construction costs increases more than 70%. B/C is evaluated large because the utilization of already exiting infra lowers the initial cost. As one of mass transportation system of large capacity, metro rapid transit can generate significant spillover effect: It will strengthen competitiveness of metro area by connecting cities within the area and by extending one-day life zone of the area, to say nothing of the benefit of improving traffic condition. The construction of metro rapid transit network is necessary for the mass transportation system of Yeongnam area as well as Daegu area, and it may work as a starting point for uniting Daegu and Gyeongbuk and strengthening regional competitiveness.

PRT(Personal Rapid Transit) is alternation mode of auto and advanced transportation system as future transportation mode cope with the situation caused by increasing traffic demand, vehicle, environment, energy problem. but there is no place where PRT is operated therefore it is necessary of study on application of PRT The purpose of this study is putting into shape of fundamental notion and role of PRT as transit system and studying of domestic application possibility We expect that PRT make transit will make variety and be able to connect with mass transportation facility, have a connection between trunk line and branch line, be a effective local transportation system within CBD, be a transportation system within leisure complex. This study focus on connection with mass transportation facility in the middle of 5 type, we class as. and we investigate application of PRT by process of making a choice applicable case area

There are many exclusive freight cars in railway freight transportation system. Gondola is one kind of freight cars. Gondolas have a role to carry bulk-type cargo such as coals and ores. A few problems are occurring due to exclusive freight cars. Operation company has redundant freight cars because exclusive freight cars can carry limited items. And purchasing cost of freight cars is higher and higher because of irregular bid. Operation efficiency of gondola is very low because return time of gondola is much longer than that of container car. In this study, we analysed the introduction effect of hopper-type container for through transit. First, we identified the characteristics of spatial distribution on freight stations. And we provided the effect of hopper-type container in terms of operation efficiency, cost reduction, new demand excavation and image enhancement of eco-friendly railroad.

There should be a need for measures to build up environmentally friendly transport system with new town for residence being built near metropolitan area. In order to promote the development of station influence area, convenience for public transport users and LRT(Light Rail Transit) construction, request for the speed improvement of urban transit is on the rise for easy access to the metropolitan area. This paper delves into the efficient operation of high speed train suitable for passenger demand estimates, and seeks to ensure integrated transportation system with subway Line 9 following the construction of Gimpo urban railway.

The interests of the government and civil business owner against the Light rail transit are increasing, it may be caused by the enterprise conception which does not consider a city circumstance that the construction plan is insensitively performed. This article present the forecast method of minimum transportation demand which secures a profitability. If It is in advance investigated the number of passenger using the existing traffic system of the area, it will be possible that the LRT project is planned on a realistic basis.

Promote competition in local government and the construction of a subway construction in the vicious cycle of debt due to the operating deficit as a greater burden on local finances was leave. This government policy of public transport in the center of the metro construction costs affordable and to respond appropriately to public transport demand new transit LRT(Light rail Transit) by introducing the current Busan was the opening of Line 4, yongin line, Busan - Gimhae line, parliamentary and barge construction or ready for the opening. What is light rail, compared to the existing subway and cheaper construction cost, the existing road or bridge that runs along the track is installed, etc. Manless system construction cost and operating expenses as a possible new railway transportation has been a leading state-of-the-art mad. However, the domestic business system engineering of light rail-related companies in the developed countries are doing to advance to the national to the local engineering skills of the self-free, hurry will have to be secured. Therefore, this paper applies local light rail project on the status of the systems engineering analysis and based on this source of the latest engineering technology-intensive systems engineering to provide direction to the development of technology.

The Bimodal Tram being developed in Korea is a new transit system that provides both benefits of rail and bus systems in terms of accessibility and fixed time schedule. This study accomplished a feasibility study for introducing the Bimodal Tram system by considering the travel demand and existing transit system at a city level based on its population. The feasibility of Bimodal Tram system varies depending on cities with respect to demographic scale, mode shares, and operational distances. The strategies introduced here will help any cities where transport agencies are trying to introduce the Bimodal Tram as a new transit system.

The existing city which consists of the downtown in Korea has been built spontaneously, and it is in difficulties for the distribution problem and traffic congestion since undersupply of social facilities cannot afford to handle the increasing traffic demand. So the traffic facilities have been reinforced to increase the competitiveness of the city and solve the related problems. The need of a new transit system considering the transport capacity and environment-friendliness is emerging as revitalization of public transportation is needed for reduce of personal transportation. In case of local governments that the Self-Reliance Ratio of local finance is high, if they promote the business by tram transit low which period could be shorten, it can correspond the traffic policy and invigorate the introduction of the new traffic system.

New transport technologies have been rapidly developed and various transport systems are ready to introduce. However, there no exists effective decision making tools for pre-feasibility studies on transport systems. The pre-feasibility studies should provide reliable solutions about whether a certain transport system is feasible or not by cost-benefit analysis and effectiveness test of enhancing regional economy. This study introduces the smart transport investment/information system (SMARTIS) for supporting decision making with ease, fast and reliable methods. The SMARTIS incorporates travel demand estimates into the process of feasibility studies with automatic data processing methods to give reliable solutions quickly. The SMARTIS is expected to be informative for transit agencies, planners, and operators.

The Bimodal Tram being developed in Korea is a new transit system that provides both benefits of rail and bus systems in terns of accessibility and fixed time schedule. The Bimodal Tram will change the role of transit system in Korea. This study developed a strategy of introducing the Bimodal Tram system by considering the travel demand and existing transit system at a city level. The transport/transit system varies depending on cities with respect to demographic characteristics, financial capabilities, etc. The strategies introduced here will help any cities where transport agencies are trying to introduce the Bimodal Tram as a new transit system.
