Inspired by the success of the High-line project in New York, The Seoul Metropolitan Government launched a project to convert an overpass near Seoul station into a pedestrian park. Seoullo 7017 went through instant success after its opening in May 2017; however, there is a continuous controversy over its long-term impact as shown in the exemplary cases like the High-line project. This study aims for quantitative investigation through the comparative analysis between Seoullo 7017 and the High-Line in the perspectives of spatial configuration. Space Syntax was chosen as the analysis method for this research. Integration (3) in Space Syntax is known to have a high correlation with pedestrian volume; thus, by using this method, spatial structure was analyzed by comparing the statistically verified results of changes in the spatial structure of the Highline with those in Seoul. The results indicated that the influence of Seoullo 7017 was less than that of the High-line in terms of spatial configuration. The reason for this difference is spatial configuration between Manhattan and Seoul. The High-line is located in Manhattan which has an urban grid structure, whereas Seoul has non-geometric urban structure, the neighborhood unit in Korea. Also the center of the overpass isn't connected well with its surroundings.

Due to the decline of a rural community, traditional periodic markets regarded as a center of an agricultural village have been gradually downsized. While researchers have made a counterproposal to revitalize the traditional periodic markets, there has limit in examining how space structure of the traditional periodic markets affect visitors. Thus this study aims to analyze space structure and visitor circulation using a space syntax, a quantitative analysis focusing on PyeongChang Daehwa market. The finding revealed high degree of unification and clearness which means overall space structure was efficient for visitors to recognize and move across the space. However, there is required to build strategies encouraging consumption. The result of analyzing visitor circulation showed the degree of unification is the highest in visitor circulation where center of the market or main facilities is located. In sum, in order to revitalize deserted traditional periodic markets, rural communities need to work out strategies to encourage consumption and expand both information desk and convenience facilities.

The spaces have a variety of sizes dependent upon their function and significance as well as their geometric shape. An architect Adolf Loos (1870-1933) had incorporated a correlation between the unconstrained formation of space into design. He had noticeably revealed the features of space that are unconstrained and mutually related with each other, for the space compositions among modern architects. This study is about to analyze the feature of space structure for houses of Adolf Loos through Space syntax which is the quantitative space analyzing method for the subject of his detached houses. These houses were emphasized for functional aspects of space without unnecessary decorations. Le Corbusier's Villa Savoye was analysed along with it to review a comparative point of view of his house's characteristic. Based on this, the features of the spatial structure of Loos' house were examined in conjunction with his views space as essence. A J-Graph and VGA for Adolf Loos' detached house revealed the structure's spatial characteristics in which the interior space is located deeply removed from exterior yet it is integrated as a whole. Also, it revealed that the experiments of the various spatial structures shown in Adolf Loos' detached house and European rationalist architects like Le Corbusier affected each other at the same time.

Ensuring walkability in a city where pedestrians and vehicles coexist is an issue of critical importance. The relative relationship between vehicle transit and walkability improvements complicates the evaluation of walkability, which thus necessitates the formation of a quantitative standard by which a methodological measurement of walkability can be achieved inside the pedestrian network. Therefore, a model is determined whereby quantitative indices such as, but not limited to, experiences of accessibility, mobility, and convenience within the network are estimated. This research proposes the integration of space syntax theory and the logit path choice model in the evaluation of walkability. Space syntax theory assesses adequacy of the constructed pedestrian network through calculation of the link integration value, while the logit model estimates its safety, mobility, and accessibility using probability. The advantage of the integrated model hence lies in its ability to sufficiently reflect such evaluation measures as the integration value, mobility convenience, accessibility potential, and safety experienced by the demand in a quantitative manner through probability computation. In this research, the Dial Algorithm is used to arrive at a solution to the logit model. This process requires that the physical distance of the pedestrian network and the perceptive distance of space syntax theory be made equivalent. In this, the research makes use of network expansion to reflect wait times. The evaluation index calculated through the integrated model is reviewed and using the results of this sample network, the applicability of the model is assessed.

This study aims to develop a framework to estimate mobile source emissions with the macroscopic travel demand model including enhanced estimates of intra-zonal travel emissions using Space Syntax analysis. It is acknowledged that "the land-use and transportation interaction model explains the influence of urban structure on accessibility and mobility pattern". Based upon this theory, the estimation model of intra-zonal travel emissions is presented with the models of total travel distance, total travel demand, and average travel speed of intra-zonal trips. Thess statistical models include several spatial indices derived from the Space Syntax analysis. It explains that urban spatial structure is a critical factor for intra-zonal travel emissions, which is lower in compact zone with smaller portion of land area, lower sprawl indicator, and more grid-type of road network. Also the suggested framework is applied in the evaluation of the effectiveness of bicycle lane project in Suwon, Korea. The estimated emissions including intra-zonal travel is as double as the results only with inter-zonal demands, which shows better performance of the suggested framework for more realistic outcomes. This framework is applicable to the estimation of mobile source emissions in nation-wide and the assessment of transportation-environment policies in regional level.

The spatial structure analysis using the existing space syntax has a weakness only to apply the road factor. Hence, it is necessary to perform a new spatial structure analysis considering the regional characteristics factor as well as the road factor. The purpose of this study is to propose a modified spatial structure analysis which adopts road and regional characteristics factors using the existing space syntax and GIS and then to apply it to the spatial structure analysis of the urbanized areas in Hapdeok town. For the new analysis, the experts' survey has been conducted to derive the spatial structure factors of the area and their relative weights. Specifically, it drew the road factor as well as the regional characteristics factors such as road, district, land value, and building density. This study shows that the existing spatial structure analysis considering only the road factor does not reflect the actual spatial structure but the modified spatial structure analysis considering the road factor and the regional characteristics factors more accurately analyzes the spatial structure of Hapdeok town. Hapdeok is not an area where road networks were developed along main development axis and its centrality was changed, but an area where road networks were developed by effectiveness and equity and its centrality was changed by downtown decline. The towns like Hapdeok is more suitable for applying the modified spatial structure analysis method considering the regional characteristics factors. Further research is required for selecting characteristics factors and appropriate parameters in the modified spatial structure analysis. Further case studies await in other cities for conducting its verification.

This study aimed to systematically adjust rural area development projects that have been carried out by a variety of government departments for activation of rural areas and overcome inefficient problems caused by the policies and projects promoted separately. As its alternative, this study aimed to explore efficient improvement scheme of rural villages associated with various projects. Major agriculture/rural policies and projects that have been promoted were classified by the target space of the policies and projects as Environment space, living space, and production space. Each space was categorized into five sub-items without duplication. By assessment results of rural area improvement level and preference by Analytic Hierarchy Process(AHP) method, maintenance of rural areas was classified into four types. And outer space structure was analyzed by using Space Syntax Method(SSM). Based on the analysis result above, facilities for improvement of rural villages were placed around representative facilities. Facility allocation was based on selection and concentration in terms of facility maintenance and on type attributes in terms of spatial aspects. And finally, alternatives schemes for setting up the basic direction of improvement of rural villages are local area characteristics and environmentally conscious business plan.
