최근 도시 인프라의 건설과 운영을 위하여 민자유치사업들이 급증하고 있다. 이러한 민자유치 인프라 프로젝트들은 국가 재정 부족의 보완과 창의성 및 효율성 향상을 통해 지역발전을 촉진하기 위한 것이라고 강조되지만, 실제 시장 메커니즘에 따른 민간자본의 새로운 투자 영역 확대와 이윤기회의 보장이라는 신자유주의적 도시정책에 따른 것이라고 할 수 있다. 이로 인해 한국에서도 1994년 이후 이러한 민자유치사업이 본격화되고 있지만, 실제 여러 가지 문제점들을 노정시키고 있다. 본 연구의 사례 분석 결과, 민자유치에 위한 범안로의 건설 및 운영에 있어 과다한 계획 교통량 예측 문제, 공사비 과다 계상 및 부대사업 조건의 문제, 사업 주체의 비합리적 운영과 회계 문제, 실시협약 내용 변경의 문제, 최소운영수입 보장 문제 등이 지적될 수 있다. 이러한 문제들을 안고 있는 범안로의 합리적 운영을 위해 가능한 대책으로, 통행료 수입 존대 방안, 재정 지원 축소 방안, 일부 구간 운영권 회수 방안, 전체 구간 운영권 회수 방안 등이 고려될 수 있다.

This paper is concerned with an estimation of optimal investment of road sector in 1996-2005. The main method is a Computable General Equilibrium (CGE) Model for Korea in which the optimal solution is derived in a recursively dynamic path. The model is composed of three main modules: the supply, the demand and the price. In this paper, the investment demand for the road is optimized with subject to national economic growth and price inflation. If the annual inflation level and the economic growth rate during 1996-2005 are set to 4.5%-5.0% and 6.0%-6.5% respectively, the optimal demand for the road investment is estimated as 155.1-180.1 trillion Won or 3.33%-3.89% of the GDP for ten years. It implies that the additional increase of the road investment by 0.61%-1.15% of the GDP is required for sustainable economic development, since the share of the road investment in the GDP of the latest 5 years has stayed around 2.27%. However, it is necessary to reduce construction investments on housing as well as to promote private financing of the road in order to maximize an efficiency of resource allocation.

PURPOSES : This study is to suggest the Influence of road capital to industry and productivity growth in South Korea. METHODS : Based on the literature review, The relevant policy questions addressed in this report are : cost reduction and Scale elasticities of road, effect of road capital stock on demand for labor, capital and materials, marginal effect of road, industry TFP growth decomposition. RESULTS : The marginal benefits of the road capital at the industry level were calculated using the estimated cost elasticities. Demand for the road capital services varies across industries as do the marginal effects. The marginal benefits are positive for the principal industries. This suggests that for these industries the existing stock of road capital may be under supplied. The contribution of road capital to TFP growth is positive in principal industries. The main contribution of road capital is in the manufacturing industries ; the magnitudes of contribution varies among industries. These results indicate that growth in exogenous demand is most important contributor to TFP growth. CONCLUSIONS : The road capital have a significant effect on employment, private capital and demand for materials inputs in all industries. At a given level of output, an increase in road capital lead to variety to demand for all inputs in all industries.

It is very costly to construct transportation facilities such as roads, bridges, tunnels, and public parking lots mainly because land price is very high in metropolis like Seoul. Private car oweners use these facilities more extensively than public transportation users. However, the government does not impose proper charges for using these facilities. Such improper charge causes traffic congestion and then decreases social welfare in efficiency and equity. To solve problem, many traffic demand management policies are used. Traffic management policies which are currently used or under consideration by the City Government of Seoul include the imposition of road tolls, increase of parking fees in public parking lots, increase of gasoline taxes, expanded implementation of bus only lanes, and shippujae, which requires one(1) non-driving day for 10 calendar days. This study examined the impacts of such policies on the different income classes using simulation analysis. We found that the impacts of market-oriented policies such as the imposition of road tolls and the increase of gasoline taxes is regressive. Also, we found that while the low and middle income private car users have incentive have incentive for public transportation use, the high income private car users have no incentive for public transportation use in many cases.

We design level 1 traffic thematic map for common data structure. Level 1 means the road that can passing cars. If public office and private company use this form, they can save amount of money from overlapping update. And widely use of traffic analysis, navigation and traffic information system. For design common data structure we compared several data structure(traffic thematic map, ITS standard node/link, Car navigation map), and generalization these characteristic data. After generalization we considered about application parts. It can use of public part(traffic analysis, road management, accident management) and private part(car navigation, map product, marketing by variable analysis) etc.

The purpose of this study is to classify the building layout and plan types according to the urban location, use and function of civil and to analyze the characteristics by the type classified. After constructing a framework (Mathia type, Nagaya type, Detached House type) for analyzing Modern Private Housing Architecture in Gunsan, the research was conducted on 30 representative buildings, and a plot plan, a floor plan and elevation were created. After analyzing the relationship between the lot of land and the urban street, we classified the type of arrangement into Mathia type and Nagaya type which directly enter the building from the road, and derived the Detached House type which indirectly enters from the road. When we look at the use of the derived arrangement types, most of the Mathia type are commercial and residential buildings, and some of them are specially designed for commercial buildings. The Nagaya type appears in the form of commercial and residential house or residential private house, and the Detached House type is classified as residential style. As a relation with the urban street, the Mathia type and the Nagaya type are generally located on the main urban street, whereas the Detached House type is located on the small urban street. As a result of analyzing, the floor plan was changed according to the plot plan. The plan of the Mathia and Nagaya type are arranged to enter directly from the street, with commercial space being mainly located on the street, and the residential space being composed on the back or the second floor. the plan of the Detached House is a type that enters indirectly into the interior through a separate space (Courtyard), and forms an organic space between the residential interior and the front and rear yard. The purpose of this study is to investigate the Characteristics of a plot plan and a floor plan of Modern Private Housing Architecture in Gunsan by means of analysis considering the urban street, Uses of buildings, Construction method and the yard through actual measurement.

Recently, BIM has been widely applying in civil engineering projects centering on the private construction industry in order to establish self guidelines for spreading in practice. However, most BIM technologies and software are based on the architectural projects. In these environments, it is not easy to apply the BIM to a infrastructure field. Even BIM standards with IFC (Industry Foundation Classes) are also focusing on architectural projects. Especially, both private and public sectors do not know about how BIM delivery system should be performed, and how such deliverable should be submitted to the government yet. Thus, we need to analyze an application level of BIM S/W (Software) in real projects and verify their interoperability. Besides, since there are not any common standards that can exchange IFC models for civil engineering projects, we have many issues in converting as-built infrastructure models into IFC and delivering their design documents to the government. Accordingly, this study aims to perform a BIM process with commercial software for real road project after a detailed design process is finished and verify interoperability between diverse BIM software for securing BIM data reliability.
