In this study, we analyzed the current situation and problems of the clustered settlement for the efficient housing redevelopment. For this, it was suggested that the alternative ways to promote the clustered settlement redevelopment. First, the result of the development types of the 10 districts, better urban development project than urban renewal project in Uiwang-si, Guri-si. Also the results of the feasibility study identified that a feasible plan of two development types about only 1 site of 10 sites and the rest of 9 sites was a appropriate for replotting method. The clustered settlement redevelopment has a limitation of projects due to the lack of feasibility and development density limit, excessive land compensation. For that reason, the settlement redevelopment are judged to promote replotting method. In particular, land expropriation method was showing the difference of feasibility, depending on the development conditions by settlements. Finally, it is necessary to improve the system for ensuring proper project feasibility, such as the abolition of urban planning facilities, additional release of green belt. And need to support from the government to induce a balance of publicity.

Land uses and land prices form a cluster spatially influenced by adjacent area and the cluster changes temporally. However, previous studies in Korea are limited to verifying a spatial autocorrelation of land price or to confirming the superiority of price models adjusting spatial characteristics. It is needed to confirm spatio-temporal changes in land market and to determine their characteristics. This study analyzed the land price volatility in time series at all local areas nationwide to confirm the spatial autocorrelation of land price. Moran index of land price change was calculated; relevance between Moran index and economic variables were analyzed and their local spatial distribution patterns were analyzed. Spatial characteristics of land price fluctuation with time in Korean land market were derived and their implication for a policy decision was drawn. As a result, spatial autocorrelation of land price fluctuation differed with time at both nationwide market and Seoul metropolitan market. The spatial autocorrelation showed an inverse proportion to land price volatility and national income. Moreover, the cluster area where the land price volatility forms a group was variable temporally.

This study categorizes types of Seoul’s subway station areas by the diurnal pattern of transit ridership at peak and non-peak times using cluster analysis. Principal component analysis was then conducted to reduce many overlapping land use variables to latent factors, which in turn were used in a multinomial logit model to analyze the relationship between the diurnal pattern of rail ridership and the land use patterns of different station areas. Unlike studies that use a fixed time frame for morning and afternoon peak periods, this study identifies the position of a ridership concentration for each station by comparing the average ridership of half-hour intervals throughout the day. The study finds six main categories of ridership diurnal pattern and shows that the starting position and duration of peak periods vary by station area and that the level of transfer ridership also varies by time and by station type. Moreover, the results demonstrate that the diurnal pattern of subway ridership is closely related to land use, block and lot size, and accessibility of bus services in the station areas.
