정보과학기술의 발달 등으로 미래도시는 많은 변화가 예상되며, 이로 인한 여러 가지 부정적인 영향도 예측되고 있어 개인적이고 비인간적인 사회출현도 우려된다. 그러나 지금까지의 도시발달과 흐름을 살펴볼 때 급격한 사회변화에 대한 역기능에 대해 방어수단을 마련하고자 근린체계가 잘 조성된 쾌적하고, 안전하며, 그리고 무엇보다도 좀 더 인간적인 모습을 갖추기 위한 다양한 노력이 시도될 것이다. 향후 미래도시에서는 보다 인간적이고 커뮤니티가 활성화된 도시를 구축하기 위해 공원녹지도 중요 수단의 하나가 될 것으로 보인다. 미래도시 유형의 하나인 V-CITY의 발전방향을 예측하고 살펴봄으로써 공원녹지의 바람직한 발전방향을 마련해야 할 것이다.

Recently the existing urban facility management integrating with advanced IT has been created more effective and various service for solving the problems what are the inadequacy of operating system, data continuity and expandability, etc. Therefore this study analyzed the research trend of BIM based urban facility maintenance, and implemented the environment with smart facility maintenance function and facility information system. Also this suggested the BIM based maintenance system framework after considerations as system operation and construction are deducted for development of system managing urban facility like bridge and tunnel. The output will be used as preliminary data for the study of development of maintenance system and derivation of real scenarios.

In autumn 2000, the Korea Ministry of Construction and Transportation (MOCT) announced that Daejeon metropolitan city, Jeonju and Jeju were chosen to showcase deployment of Intelligent Transportation Systems(ITS). The program called the Advanced Transportation Systems Model Deployment Initiatives makes a significant step in Intelligent Transportation Infrastructure (In) in Korea. The Initiative is poised to increase the performance and efficiency of the area's roadway and transportation systems to meet growth demand. Three citie's $\$$50 million Model Deployment Initiative project is poised to increase the performance and efficiency of the area's roadway and transportation systems to meet growth demand. The effort particularly focused on the traveler information systems that should raise the level of ITS awareness in Korea. In this paper, project management, funding, private investment, procedures and detailed review of ITS Model Deployment Initiatives are discussed.

본 고는 대전광역시 첨단교통모델도시 건설사업의 일환으로 구축된 DSRC(Dedicated Short Range Communication) 기술을 활용한 교통정보시스템 구축 사례를 소개함을 목적으로 한다. 공공부문에서의 구간정보 수집 및 가공 체계 구축은 본 대전 ITS 사업이 처음이며 더욱이 DSRC 기술을 구간정보 수집에 적용한 최초의 시도이다. 이에 시스템 구축과정에서 적지 않은 쟁점이 도출되었고, 많은 시행착오를 통해 그 해법을 찾아가며 현재 운영중인 시스템을 완공하게 되었다. 노변기지국(RSE)과 차량장치(OBE)간의 통신에 의해 수집된 자료는, 필터링, 검지기 지점정보, 패턴데이터 등과의 자료합성, 평활화, 통계정보 및 패턴정보 생성 등의 과정을 거쳐 구간소통정보가 산출된다. 현재 운영중인 본 시스템은 향후 지속적으로 보완 발전시켜 나가야 하며, 이를 위해 프로브 수집체계 보완, 시스템의 성능평가, 패턴데이터의 적절한 유지관리, 알고리즘의 지속적 발전 등을 향후과제로서 제시하였다. 본 고는 ITS사업에 있어 중요 쟁점중에 한 분야인 소통정보의 가공 절차를 공유함으로써, 관련 분야의 기술개발 촉진과 향후 유사시스템 구축의 시행착오를 줄이는데 기여할 수 있으리라 판단된다.

본 연구에서는 해안 도시 하천의 범람으로 인한 홍수 재해 발생시 예상될 수 있는 피해에 대해 적절한 홍수예경보 및 피난대책을 수립하고자 대표적인 해안 도시 하천의 특성을 가지는 부산시 온천천 유역을 대상으로 수치지도에서 각종 지형자료를 추출하였고 수문 GIS 자료를 구축하였다. 그리고, 하천 수리 분석을 위한 한계유출량 산정을 위해 HEC-RAS 모형을 이용 조위의 영향을 고려하여 홍수위 및 한계유출량을 산정하였고 수문 분석을 위한 도시 돌발 홍수 기준 우량 산정을 위해 PCSWMM 2002를 이용하여 기준 우량을 산정하였다. 전형적인 해안 도시 지역 유역 특성을 나타내는 부산시 온천천 유역에 대한 경보발령 기준을 설정하기 위하여 선정지점 세 곳의 한계수심 $H_{c1},\;H_{c2},\;H_{c3},\;H_{c4}$가 발생할 수 있는 강우량(위험 홍수량을 유발하는 위험 강우량(Trigger Rainfall))을 산정하였고 PCSWMM을 이용한 모형화 기법으로 해안 도시 돌발 홍수 기준 우량을 산정하였다. 산정 결과 온천천 유역의 홍수예경보 시스템과 이에 따른 홍수예경보 발령흐름도, 운영체계가 결정되어 해안 도시 돌발 홍수예경보 방안이 구축되었다. 해안 도시의 홍수 관리는 도시 우수 시스템, 하천, 해안 특성이 복합된 문제이다. 현재 해안 도시 지역의 홍수예경보 시스템 구축 실적이 전무한 실정임을 볼 때 현실적으로 실용화 할 수 있는 시스템 개발을 해내는 것이 무엇보다도 시급하고 중요한 문제이다. 앞으로 더욱 심도있게 연구하여 주요 하천에 대한 홍수예경보 시스템 구축이 절실히 요구된다.

This study aims to find out the construction process and planning characteristics of Suwon and Hwa-sung in 18th century from the point of water system. This study has an explanatory approach. The planning intents in the water system was driven out by analyzing various planning elements in relation to water system in the process of constructing Hwa-sung in 18th century. Using Entire Map of Hwa-sung, land registration map made in 1911 and topographic map of 1/10,000 scale made in 1917, water system and interpretation of spatial structure in Hwa-sung were analyzed. The results are as follows(Planning characteristics of the water system in Haw-sung in 18th century are as follows). Firstly, in determining the spatial structure and location of Hwa-sung, water system had an important role. Secondly, integrated drainage system was planned by the organization of natural and artificial water stream. Thirdly, the main street system and land use structure were planned in relation with water system. Fourthly, territoriality of main area was planned with water stream. Fifthly, ponds were constructed for flood control and they had important role as landscape elements. Sixthly, water stream was used as intentional BiBo element. As a result of the study, the weater system of Hwa-sung in 18th century was planned by the organization of natural and artificial water stream in relation with the location of new town and wide area's spatial structure, street system, land use structure, territoriality of main area, terriflood control, water quality protection, landscape, 비보 and urban daily life.

Landuse information is base data being applied as common database in the process of executing urban project service and is very available. But, the progress of business on landuse information building is deficient yet. In this study, we'd like to deal with landuse information projet that is the base of urban project, many landuse information building and the method of extraction of efficient second-information. Also, we built system to apply actively landuse information for urban projectors. And, we'd like to present the model on urban landuse classification system that wouldn't be standard yet by studying the method of urban landuse pattern using landuse in-formation being built. Also, we can evaluate if the model of urban landuse pattern comes up to present landuse. We can expect it is a base data by extracting unsuitable area from present landuse efficiently when we construct landuse project.

The amount of energy consumed by a transportation system in a city is influenced not just by a transportation system itself but also by city's spatial character. Yet there have been very limited studies on this subject. This study investigates the factors that influence the energy consumption by a transportation system and city's spatial character. The model of an urban area confined within a definite boundary is assumed in order to develop the relationships between the energy consumption and the transportation system. Various assumptions on the character of a city and activities are made. An equation for computation of the energy consumption is derived with such factors as modal split, densities of residents and workers, as well as technological development. Using the equation, sensitivity analyses are performed in order to identify the relationships between energy consumption and influencing factors. It is found that the modal split is the most powerful factor that determines the energy consumption by the transportation system. Yet it is also found that the densities of residents and workers and the technological factors are very important in determining the amount of energy consumption as well.
