What benefit items from railroad investment are evaluated, and how those items are quantified have profound impacts on the feasibility of the proposed investments. They also have implications on the projects priorities, not to mention on intermodal comparison between highway and railroad. Evaluation procedures currently being utilized in Korea show limits in fully evaluating railroads' investment impacts. Economic and practical implications are evaluated for including revenues for railroad investment. Based on the critical evaluation of procedures in other countries, and based on the analysis of Korea's national transportation goals, new and improved benefit items are redefined and quantification guidelines are proposed.

This study measures the investment effects of railroad industries on Korean economics, using the table of industry relation analysis. Until now, few studies have analyzed the economic effects of railroad in Korea so that this study can have a big implication for transportation policies in making decisions on its investment level as top priority. This study finds that railroad investment effects are larger than those of road on the national economics and, thus, impling that the expansion of railroad investment is required to grow continuously national economics as well as a major modal of transportation networks.

It is a plan the government increases a railroad section SOC investment, and to activate railroad construction while a railroad wins the spotlight with green transportation. But an error of the demand forecast that is a base of a railroad investment evaluation follows in occurring big, there is it with an operation with an obstacle of a railroad investment. Case of the Incheon International Airport Railroad which went into operation recently, While a present transportation demand showed about 10% than a demand forecasted in a past conference, it was magnified in a social problem. A lot of research was gone on in road project about traffic demand forecast and error, a study to find out the error cause is an insufficient situation although errors of a railroad occurs big. So, this study looked for errors and causes about trip generation model and modes sharing model of railroad demand forecast but it was defined causes so that it can occur similar problems in the future. Especially it investigated causes after comparing rate of development plan for the realization and O/D size in trip generation model and after comparing rate of modes sharing of past and current and conducting a survey for airport users. In conclusion, it suggested method to reduce errors of railroad demand forecasting in the future.

Korean government announced long-term railway safety investment plan for the safety improvement by 2020. But no research have been done about differential analysis on railroad safety investment and safety improvement. In this study, recent 10 year data on safety investments and accident data are analysed for the differential analysis. Three main safety investments are analysed on regard to accident rate and accident fatalities. Three safety measures include level crossing accident, platform fatalities, and track trespass fatalities. About 90% of railway accident fatalities are caused by these three kind of accidents. Differential analysis shows about 4 to 6 years delay after railroad safety investment and safety improvement. This result can be utilized for the decision making on safety measures and safety target. Which required long term approach.

Each nation of the world is intensively propelling the R&D investment to solve the financial crisis and worldwide economic recession occurred from last year. This means the world economic is under economic system based on the knowledge. So, The R&D is continuously propelled for possession of the technology through the R&D stock and which is core in the knowledge based economic system. In this world stream, our government is also increasing the R&D investment and checked the technology level through surveying the R&D stock and corn parison of each industry or world. The R&D investment of the railroad is continued but there is no data of the R&D stock. So, surveying the railroad R&D stock and comparing with korea industry is processed.

신성장이론에서 R&D Stock은 노동과 자본 외에 제3의 생산요소이다. 이 관점에서 R&D Stock은 기존의 자본처럼 비용이 투입되어야만 축적이 가능한 자본의 위치를 차지하게 되며 이것을 지식자본이라고 한다. 이러한 지식자본을 향상시키기 위한 노력이 R&D투자이며 이의 축적이 R&D Stock이다. R&D Stock과 총요소생산 성과의 관계를 추정함으로써 경제성장의 기여도, R&D 투자의 수익률 등을 분석한다. 본 논문에서는 철도 R&D 투자에 대한 R&D Stock을 분석하고 기술수준과 비교 한 결과 R&D Stock이 증가하면 기술수준도 비례적으로 증가되었다. 그리고 GDP에 대한 철도산업의 비중과 전 부문에 대한 철도 R&D Stock 비중을 비교한 결과 철도산업의 비중에 비해 철도 R&D Stock 비중이 상대적으로 작아 지속적인 철도 R&D 투자가 필요함을 알 수 있다.

국제적인 철도 사업은 개도국의 재정 부족 등 다양한 대외적 환경변화로 인해 재정사업에서 민간 투자사업(PPP)으로의 변경이 보편화되고 있다. 하지만, 철도 시설물은 도로 등 다른 인프라 시설물 보다는 철도 생애주기 특성상 사업개발, 건설 및 운영단계까지 막대한 건설자금 및 O&M 비용이 소요된다. 따라서 투자 대비 일정 수준의 수익률이 보장되지 않는다면 해외 특히 예측불허한 상황들이 발생하는 개발도상국에서의 해외철도 민간투자사업의 수행은 매우 어려운 실정이다. 본 연구에서는 글로벌 철도시장 동향 정보 및 기존 문헌 고찰을 통해 국내기업의 해외철도 민간투자사업 진출시 취약점 및 위험요인들을 살펴보고 그 의미와 대응 방안들에 대한 논의를 통하여 해외철도사업 진출시 국내기업의 경쟁력을 강화하는 방향을 제시하고자 한다.

Reliable external cost must be estimated to achieve the optimal market share between transportation modes. In this paper, we determined the market share between railroad and road on the cost minimization base. The results show that optimal market share is achieved by increasing investment on railroad.

최근 정부는 지속가능한 녹색성장을 위하여 도로 중심의 교통체계에서 친환경 고효율의 교통수단인 철도중심의 교통체계로의 전환을 적극 추진하고 있다. 철도망을 통해 국토를 통합 다핵 개방형 구조로 재편하고자 철도부문 최상위 계획인 제2차 국가철도망구축계획을 고시('11.4)하였으며, 전국 주요거점을 일상 통근시간대인 1시간 30분대로 연결하여 하나의 도시권으로 통합하고자 하고 있다. 그러나, SOC사업의 타당성분석을 위한 비용편익분석방법론에는 철도사업의 특성이 반영되지 않아 철도사업이 도로사업에 비해 불리한 실정이었다. 이를 개선하기 위하여 철도시설공단에서는 철도투자 평가체계 개선방안 연구를 시행하였으며, 기획재정부에서는 철도투자평가체계 개선방안에 대한 많은 내용을 도입하여 철도부문 예비타당성조사에 대한 개선사항을 예타지침에 적용하였다. 본 논문에서는 철도투자 평가체계 개선방안에서 주요하게 논의된 사항인, 분석기간, 할인율, 통행시간절감편익, 교통사고절감편익, 차량대체 투자비 및 고속철도 운영유지보수비 부분에 대한 고찰을 하였으며, 아울러, 추가로 연구되어야할 부분에 대하여 알아보고자 한다. 이러한 개선 방안들이 향후 철도부문 타당성평가 방법론에 반영됨으로써 합리적 객관적인 철도투자 평가체계 구축이 가능할 것이며, 또한 선순환적인 철도투자가 이루어질 수 있을 것이다.

PURPOSES : Lots of criticism such as over/duplication investment, inconsistency of the policies among local governments and national plans etc. has been aroused due to the policy of supply-driven construction for transportation facilities. Recently, according to the environmental-friendly transportation policy, the investment of railroad has been expanded gradually, however the duplication with existing road facility makes it difficult to construct railroad. Thus it is necessary to evaluate the interrelationship between new project and existing facilities in the planning stage. However the method and the criteria for analyzing the duplication and over-investment of projects are not established in the manual, thus the feasibility of these projects are carried out from the economic point of view. METHODS: First, It reviewed about interrelationship criteria(domestic, overseas) and proposed implications and this study directions. Next, It developed the methods of evaluating independency, competitiveness and complementarity. RESULTS : In this study, the methods of evaluating independency, competitiveness and complementarity etc. are suggested to analyze the interrelationship between transportation facilities. The case study was carried out to examine the applicability of the methods. CONCLUSIONS: The methods raise rationality of decision-making compared to existing one. In the future, these methods are introduced into the manual of pre-feasibility study and feasibility study, more efficient decision-making and investment are expected.
