Although infrastructure cost comprises the great proportion of residential development cost, all of it tends to be borne by land developers which develop large area. This brings about free-riding by adjacent small development or built-up area, followed by the equity problem in terms of infrastructure development cost sharing and the privatization of development gain. This study aims to establish the method to analyze free-riding on the transportation infrastructure(roads) and investigate empirically how much the free-riding occurs. It sets several development scenarios to calculate the part generated by Bucheon Sangdong district, the case area of this study, of all the traffic flow on the roads. The Network analysis is used to estimate the proportion, by development scenarios, of traffic flow, travel time, and travel cost. As a result, the developer of Bucheon Sangdong district is responsible for 83% of the construction cost of selected roads. The methodology and empirical result of this study would contribute to determine who are liable for the infrastructure facilitation and to estimate how much of the cost the obligators have to share.

Urban design is a specific and detailed action plan which regulates from the development plan to the architectural characteristics of every building and now many new towns by Urban design has been developed after 2000. But recently doubts about the effectiveness of Urban design have been raised in locals. The purpose of this study is to verify the effectiveness of urban design in terms of residents, through case study and the survey of resident's satisfaction on Urban design guidelines. The result of survey of resident's satisfaction on Urban design were above-average satisfaction. And main factors influencing to the resident's satisfaction are the public infrastructure factors, transportation factors, development density factors, and pedestrian environment factors, urban landscape factors. And the total satisfaction was most influenced by the public infrastructure factors among the five factors. To improve the effectiveness of urban design, it is necessary to build specific planning and guidelines to the general.

사전재해영향성검토 협의제도는 개발로 인해 발생할 수 있는 재해유발 요인을 사전에 검토하여 이를 사전에 제거하는 것이 목적이다. 사전재해영향성 검토는 1996년부터 시행한 재해영향평가의 한계점을 보완하기 위하여, 2005년 개정된 자연재해대책법에서는 사전재해영향성 검토협의제도를 포함하였으며, 2005년 8월 17일 동법 시행령을 개정 공포하여 사전재해영향성검토 협의제도를 본격적으로 시행하게 되었다. 본고에서는 사업 대상 지구를 "부산장안지구 택지개발사업(1단계)"로 선정하였으며, 개발에 따른 재해 발생요인, 즉 유출량 증가에 따른 하류부의 홍수피해 가중, 토공 공사에 따른 토사유출량 증가, 절 성토계획 따라 유발되는 사면의 불안정에 대한 사전검토를 목적으로 하였다. 사업시행에 따른 개발중 토사유출량의 증가와, 개발후 홍수유출량의 증가로 재해의 위험이 예상되어 개발 중의 임시저류지 겸 침사지 2개소와 개발 후의 영구저류지 1개소를 계획하여 홍수유출량을 $2.48m^3/sec$을 줄이고, 토사유출을 90% 포착하였다.

The purpose of this study is to analyse the pedestrian environment of the residential area in residential development. The result of the research are follows; first, the pedestrian environment in the apartment quarter is better than independent residential quarter. second, the pedestrian and the automobile use together the street, because the side walk ist not established from the road where the width is narrow. finally, the condition of side walk paving ist bad, so that the pedestrian environmental level decreased badly

${\cdot}$ 한국토지개발공사는 전국 37개 택지개발사업지구에서 단독주택지 5,493필지(361,127평), 상업용지 및 업무용지 1,465필지(389,736평)을 수의계약의 방법으로 매각하고 있다. ${\cdot}$ 수의계약으로 매각하는 단독주택지를 매입하는 경우에는 주택공급에 관한 규칙 제 17조의 규정에 의한 아파트 재당첨금지 규정 (민영 5년, 국민 10년)이 적용되지 않는다. ${\cdot}$ 토지시장이 비수기이고 현재 토지가격이 부동산 경기의 침체국면에 있는 가격임을 고려할 때 실수요자에게는 유리한 상황이라 할 수 있다.

최근 국내 주택시장에서의 관심은 수요와 공급의 불일치 해소이다. 이를 위해서는 정확한 수요권역 설정에 의한 사업지구별 수요예측이 필수적이다. 본 연구에서는 주택시장권역 설정 시 선행연구에서 사용하는 가구이동자료 기준의 수요권역과 청약자 주소지에 의한 실제 수요권역의 차이를 비교분석 하였다. 수도권 3개 택지개발지구를 대상으로 한 실증분석 결과, 청약자료에 의한 실제 수요권역은 가구이동자료 기준의 수요권역에 비해 확대되는 것으로 나타나 기존의 가구이동자료 기준에 의한 수요권역 설정의 보완이 필요한 것으로 판단된다. 특히 사업지구와 서울 도심과의 거리, 핵심 수요권과 배후수요권의 수요구성비와 같은 입지경쟁력, 개발규모(신도시급 여부) 등의 변수가 정확한 수요권역의 설정을 위해 우선적으로 보완되어야 할 변수로 나타났다. 또한 동일 사업지구에 있어서도 임대/분양과 같은 주택유형, 주택의 규모에 따라 수요권역의 차이를 보였다. 아울러 부동산경기 역시 수요권역의 범위형성에 영향을 미치고 있으며 정확한 수요권역 분석을 위해서는 주택가격, 사업지구 입지경쟁력 등이 함께 복합적으로 고려되어야 할 필요성이 확인되었다.

Residential land development projects are tending upwards recently. However, an indiscreet residential land development has tended to damage environment by destroying existing green lands and trees of target lands and generating many cut slopes with transformation of its topography. There are Prior Environmental Review(PER) for district designation and Environmental Impact Assessment(EIA) before approval on development plans. PER is implemented after developing a residential land development plan and EIA is implemented after completing a detail design. As the result, many of residential land development projects are passive to reduce potential environmental problems on the designated sites. Object of this study is to construct an evaluation system on alternatives in the early step of site designation for implementing residential land development projects with environment-friendly and sustainable way. For this, alternative evaluation model is constructed by using Fuzzy Inference and Analytic Hierarchy Process(AHP) method based on Environmental Evaluation Factors of residential land development project, which are proposed in the precedent research. If a decision maker evaluates environment damage by ten-point method, the point is transformed Environmental Performance(EP) by Fuzzy Inference, and then, applying weight that is already calculated by AHP method, Total Environmental Performance(TEP) is calculated. After all, an alternative with the highest TEP is selected as the best one. Using this evaluation system, more than two alternatives of residential land development project site, which can hold location appropriateness in the early under undecided land use plan, can be evaluated quantitatively. As environmental damages, which can be generated by implementing a residential land development project, can be detected in the early step, environmental damages can be removed or reduced at the source.

The purpose of this study is to analyze the impact which the plan characteristics of Residential Land Development Projects have on land price changes in the project district and to derive policy implications for the efficient promotion of these projects. For this purpose, we analyzed the promotion land price change progress of Residential Land Development Projects step-by-step. After theoretical consideration and a review of the references, 16 plan characteristics of Residential Land Development Projects affecting land price changes were selected ((1) The rate of land price change, (2) Business area, (3) Residential land ratio, (4) Commercial land ratio, (5) Semi-residential land ratio, (6) Neighborhood facilities land ratio, (7) Apartment house ratio, (8) Street ratio, (9) Park & green ratio, (10) Ratio of land for schools, (11) Site development cost for $1m^2$, (12) General residential area ratio, (13) Semi-residential area ratio, (14) Commercial area ratio, (15) Semi-Industrial area ratio, and Natural green area ratio). We used SPSS Version 20.0 to analyze the impact of the 16 selected plan characteristics on the land price changes. As a result, it was found that the land price began to rise two years (before/after?) the appointment of the district and became stabilized after the completion of the project. The plan characteristics that affect the land price changes were found to be the (2) Business area, (4) Commercial land ratio, (6) Neighborhood facilities land ratio, (8) Street ratio, (11) Site development cost for $1m^2$, and (12) General residential area ratio.

This paper aims to suggest the problems of land-use plan which causes the lack of parking space and to study the improvement of the problems. The land-use plan and the parking plan of the Gyo-dong 2 land development project are examined and the land use and the parking conditions are surveyed. The major cause of parking problem is not to have planned land use realistically. Because of the non-realistic land use plan, the parking demands are underestimated and it has resulted in decreasing the supply of parking space. In addition, the land use and parking managements have been negligent since the land development. In order to improve the parking problem, the change of land use should be considered in land use plan. And actual land use and parking plans should be made and land use management which considers the change of parking demands should be practiced.
