The urban streets as a featured and well performing public space for people should be organized in a way that can work as a whole system through network as well as that can provide amenities fur pedestrian. This is a study on Seattle's 'Blue Ring' project for an analysis focused on how its street weaving system organized and what are the design characteristics of the streets. The results are as followings. (1)Pedestrian oriented design, (2)Urban street as a part of open space that can accommodate human activities, (3)Integrated, not isolated with outer/ other open space, (4)Organically networked in a hierarchical manner that can promote pedestrian movement, (5)Utilization of regionally identical design elements. And Smart Growth concept lies in the core of 'Blue Ring' project.

Pedestrian environment not only affects the quantitative degree in pedestrian movement, but also an impact on the local economics and environment that speaks within the greater dialogue of the qualitative life in an urban context. Recent urban planning issues have matured from a linear street development to a conversion of pedestrian friendly streets that synchronizes the entire pedestrian movement structures as a whole. Subject cases, Myung-Dong and Kwanchul-Dong, were selected from time regulated pedestrian streets in Seoul. Analysis of these streets was done through field studies and interviews. From the research, the outcome was helpful in providing the developers a greater perspective with the pedestrian movement structure that is not confined to a certain parameter, but in a larger scale within the urban environment. It was also useful in justifying ambiguous locations of pedestrian-only streets and crosswalks. Also, It aided in planning optimal scheme that concurs with the predictable pedestrian movement.

Pedestrians and vehicle users should be treated with equal importance in urban street design. However, current street design suggests that the design criteria for sidewalks is based on the functional hierarchy of the vehicles, therefore it is necessary to develop sidewalk design standards that give more weight to pedestrians rather than vehicles. For this, this study suggests that the level of service of pedestrians should be considered in the process of designing sidewalks. Currently, level of service (LOS) criteria for pedestrians in the Korean Highway Capacity Manual are based on pedestrian volume, but the volume of pedestrians is seldomly estimated in practice. So, the current LOS criteria has limitations in terms of practical use. Also, the study assumes that the pedestrian flow rate is hardly the dominant factor that could affect the LOS of pedestrians at most urban sidewalks. In this context, the study considers a new LOS for sidewalk design based on the comfort of pedestrians while passing pedestrians coming from the opposite direction. Then the study attempts to link the new LOS criteria to the land use patterns using data of pedestrian traffic characteristics acquired from the field. In addition to this, the scope in which the suggested criteria can be applied is suggested.

경제적인 풍요가 어느정도 이루어지면서 깨끗한 도시환경속에서 삶을 누리고자 하는 욕구도 증가되었다. 이를 반영하듯이 최근들어 환경에 대한 시민들의 관심이 어느때 보다 더욱 커져만 가고 있다. 이와 더불어 도시계획적 흐름도 물적계획에서 비물적계획인 인간중심 위주의 가치관으로 전환되고 있으며, 공원녹지체계의 정립, 도시경관관리방안, 자전거도로의 도입, 보행자도로의 계획과 설계, 대중교통의 활성화 등 많은 환경친화적 프로젝트들이 수행되어져 왔다. 본 연구에서도 기존의 주요 보행자공간으로 다루어져 온 보도공간에 대하여 조사연구하였으며, 도심의 외곽에 위치하고는 있지만 대구시의 남북을 관통하는 주요간선도로변에 접해 있고 보행량에 비해 보도가 지나치게 넓어 비효율적인 토지이용을 보이는 보도공간을 대상으로 하였다. 특히 도심의 외곽지 보도에 관한 연구는 통행량이 많은 도심지의 상업지나 주택지의 보도에 밀려 상대적으로 소홀히 다루어져 왔다. 이 가운데 대표성과 보편성을 가지는 곳으로 선정하여 연구를 수행한 결과 기존의 단순목적 보도공간을 4개의 공간 즉 보행자공간, 자전거도로공간, 차단 및 가로시설공간, 녹지 및 편익공간으로 재구성하였다. 이는 적은 비용과 노력으로 보행의 순기능인 쾌적성과 안전성을 보다 강화시켜나갈 수 있었다. 매연과 소음이 없고 도시민의 건강성를 확보한다는 이유로 여러 선진국에서는 수 년전부터 각광을 받고 있는 것이 보행교통과 자전거교통의 개념인 녹색교통이다. 이러한 녹색교통은 공해감소의 편익도 있지만 무엇보다 매력적인 도시환경의 창출과 인간중심적이라는 가치관에 그 의의가 있겠다.

Although numerous studies have analyzed the relationship between subway travel demand (STD) and various characteristics of subway catchment area (SCA), a few studies examined the relationship between STD and the structure of pedestrian networks within each SCA. Hence, this study evaluates the structure of pedestrian networks within 79 SCAs in the city of Busan using Space syntax and investigates the relationship between STD and several characteristics of SCA including the spatial structure of pedestrian network. The analysis results show that the spatial integration of pedestrian networks within the SCAs, which represents the magnitudes of walking accessibility to subway station, is positively associated with STD among the three spatial indexes such as integration, connectivity, and intelligibility. In addition, the results show that STD significantly increases as the number of travel gathering facilities and the average floor area ratio within the SCAs increase. This study ultimately corroborates that designing the grid pedestrian network and assigning the travel gathering facilities to the compact buildings within SCAs are needed to ameliorate the spatial structure of SCA in the city of Busan as transit-oriented development system.

It is important to know pedestrian volume to carry out pedestrian safety analysis and pedestrian friendly design. However, it is too difficult to come across research work related to pedestrian volume analysis in the field of transport, due to lack of interests on pedestrian movement. Most transport research has been focused on vehicles and highways rather than pedestrian. On the other hand, in the field of urban studies, there comes an effective tool to estimate pedestrian volumes using Space Syntax theory. This theory twins out to be effective and economic because it only requires network information, which is easy to acquire from maps and field survey. However, this method is different in the way representing networks from the way that is common in the field of transport. To make up for this point, this paper develops a novel measure for estimating pedestrian volume using Dial's algorithm, and applies the model in the two test networks; Insadong and Soongryemoon networks. The application results reveals that developed measure is an effective tool to explain pedestrian volume; a correlation coefficient between the measure and pedestrian volume is 0.713 in Insadong and 0.492 in Soongryemoon, and the goodness of fit($R^2$) of regression models are 0.893 in Insadong and 0.671 in Soongryemoon. This estimation method is significantly less complicated to estimate the effect of a pedestrian network change than Space Syntax theory, which requires special softwares not readily available.

It becomes more and more important to develop various infiltration facilities for healthy water cycle and reduction of urban storm water runoff. In this study, a infiltration facility by utilizing tree box was developed. The developed facility is capable of reducing storm water road runoff, improving urban water cycle, and performing other sustainable and environmental functions. Because the facility can be manufactured to a smaller size than an existing runoff reduction facility, it can be installed at various road types of not only existing urban areas, but new developed areas. If the facility is applied to four-lane roadways, it is expected to reduce 65% of rainfall runoff discharge. Urban flood control improvement can be accomplished by a wide application of the developed technique.

Signboards are standardized according to national legislation for the safety of pedestrians and disaster prevention in urban areas. Signboards should be installed according to the standard. However, it is not easy to manage the signboards systematically due to the number of signboards that have been installed for a long time and frequently changing stores. In this study, we proposed a methodology for distinguishing signboards that deviated from the standard. To this end, the signboard was photographed using a stereo camera, and then the three-dimensional coordinates of the signboard were determined from the signboard image to calculate the signboard's horizontal and vertical dimensions to determine the signboard's specifications. In order to determine the interior and relative orientation parameters of the stereo camera, an outdoor three-dimensional building was used as the test field. Then, the image coordinates of four vertices of the signboard were extracted from the signboard image taken from about 15m ~ 22m distance using deep learning. After determining the signboard's three-dimensional coordinates by using the interior and relative orientation parameters of the stereo camera and the image coordinates of the four vertices of the signboard, the horizontal and vertical sizes of the signboard were calculated, resulting in an error of about 2.7cm on average. The specifications for the ten flat-type signboards showed that all of the horizontal sizes were compliant with the specifications, but the vertical sizes exceeded about 36.5cm on average. Through this, it was found that maintenance of flat-type signboards is needed overall.
