철도는 1899년 9월18일(노량진∼제물포)개통된 우리나라 최초의 대량교통수단임. 우리나라철도부설은 일본에 의해 대륙진출의 수단으로 이용된 타율적인면이 강했음. 그러나 호남선부설등에서는 우리민족의 자력적인 철도건설노력도 보였음. 대부분의 철도망은 식민지시대에 완성되었고, 철도네트워크는 경부선과 호남선, 경원선, 경의선을 중심으로 X자형으로 이루어져 있으며, 전쟁이후 우리나라는 산업선의 발달, 도시철도의 탄생등 주요한 교통수단으로 발전을 거듭해 오고 있음. 1960년대 중반이후 철도의 분담율이 저하되었는데 이는 자동차의 발달에 기인했다고 할 수 있으며, 이와같은 추세는 세계적인 추세였음.

Because railways themselves are not enough to provide door-to-door service, they need to be complemented by a transportation system access the stations and a convenient transfer system to access other railway lines. User friendly service policies include a faster, interconnected, and intermodal transportation system. It becomes more important to use deep subterranean space from an economical standpoint in order to promote railway construction projects. In this research, the authors dealt with construction plan for strengthening capacity of deep subterranean railways. Since deep subterranean railways are situated deeper underground than other railways, they are more difficult to access and transfer to, in addition to psychological pressure. Moreover, deep subterranean railways with high speed add access difficulties as the distance between stations increases. Therefore, the authors discuss not only systemization for uniting deep subterranean railways and other transportation facilities but also reinforcement strategies. The purpose of these strategies is so that deep subterranean railways provide mobility while established railways provide accessibility to overcome this problem.

Ecological networks can be generally classified into core areas, buffer zones, and corridors. Particularly, buffer zones connect core areas or ecological corridors, and preserve ecological network by reducing the impact from outside. We examined related laws and researches about buffer zone establishment associated with the resources of high ecological and conservation value to find out more researches are needed. In this study, we investigated various examples of the criteria for establishing buffer zones at domestic and overseas. Based on the results of railway environmental impact assessment and railway construction guidelines, we analyzed the application methods applicable to the railway development area and proposed the criteria to evaluate land cover status, species diversity, rarity, and connectivity. Through this study, the environmental and ecological value around the development area of the railroad was examined to reduce the environmental damage from railroad construction.

Recently, despite a decrease in the number of working days and an increase in the number of non-working days due to an increase in the abnormal climate and the revision of the Labor Standards Act, a standard construction period reflecting this has not been established. For this reason, even if the appropriate construction period is calculated at the site, there is a situation where delays occur due to unexpected circumstances. Therefore, this study proposes a method of calculating the number of non-working days for railway bridgework construction that reflects changes in construction conditions and climate change and reflects this to railway bridgework construction, and the number of working days was calculated. As a result, the number of non-working days by region and month in Korea was derived, and through this, the necessity of regulations and standards for appropriate construction periods reflecting regional characteristics and characteristics of each construction type was presented.

Since many resources are put into the work of changing the railway operation within limited time, it is important to have a specific work plan and safety management. For this reason, the work schedule is shared in advance, and parallel work is being carried out simultaneously by rail system, such as tracks, trolly wires, and signals. However, due to the nature of the transfer work, the work is carried out at night when the railway operation is finished, and many resources are put into the limited area of the operating line, so the risk of safety accidents and failure to change the operating line is recognized as high. Nevertheless, there is still not enough research done in korea regarding the operation line change construction. Therefore, this study is conducted a survey on the track exchange work of railroad for working people, and analyzed the results of the survey. Finally, a standard work process was suggested to reduce the risk of track exchange work.

This study aims to examine the influence of the Daegu Subway Line 3 construction on apartment price fluctuation and to find the factors causing the apartment price fluctuation in the station area of the Daegu Subway Line 3. Empirical results of this study are as follows: first, the apartment price is more fluctuated or increased at the time of completion of subway construction than at the time of breaking ground; second, the opening of the Daegu Subway Line 3 has positive impact on apartment price nearby the station area of the Daegu Subway Line 3, especially apartment prices in the second station area (200-600m) are positively related to the opening of the Daegu Subway Line 3; third, medium-large size ($85-135m^2$) and large size (excess of $135m^2$) apartment are sensitively related to the apartment price fluctuation by the Daegu Subway Line 3 construction; and fourth, Buk-gu and Suseong-gu areas are the main beneficiaries. The results of this study suggest implications for tax and redistribution policies in the station areas.

Construction and Transportation R&D budget is increased every year. Therefore, outcome is important issue. Also, we must try for practical use of outcome. And we need strategy for practical use of outcome. This is research for the application of research and development outcome. Specially, this research studies about way for construction standard. And this proposes a institutional improvement. First, it catch a problem point with present condition analysis. Second, It executes a survey and analysis. Finally it presents some policy suggestion. This research solves two problems. This applies to the field of research and development outcome. Another this amend construction standard.
