Since 2014, Japan has implemented a policy for forming a compact urban structure at a national level through an urban planning technique called a location normalization plan. A residence-induced zone included in the location normalization plan is considered as the essence of forming a compact urban structure and can be characterized as a policy that compactifies cities for a long period not only by inducing residence functions into the inside of the zones but also by applying regulations to the outside of the zones. This study examined the status of the dichotomous compact city policy applied in reality by analyzing various cases in Japan that established location normalization plans, and its implications. The conditions commonly observed in the induced zone in model cities indicated that the validity of residence-induced zones—how and where residence-induced zones had to be designated—was prioritized in many cases. Some cities, however, designated independent zones that maintained a certain level of residential functions outside the induced zones. Utilizing independent zones in non-induced zones can be assessed not as an act of simply dividing cities by a dichotomous way but as an attempt to reflect the situations and characteristics of individual cities.

This study begins with a hypothesis that pedestrian movement can be considered as an outcome of two distinct components -(1) the configuration of street network and (2) the location of specific attractions (urban facilities -shops, offices, pubic buildings etc.) within a network. The objective of this research is to investigate the relationship between geometrical factors of street network and socio-economic process between urban attractors and pedestrians. With this purpose, a new analytical model will be developed, whereby two well-known analytical methods of spatial analysis in architectural or urban field is combinednetwork analysis and multi agent system. Mainly centrality measures of network analysis will be compared to the volume of pedestrian flow from the agent simulation model. This comparison will generate a picture that demonstrates the existence of two types of factors in the performance of urban spaces. -1) from the street network which is geometrical, static, predictable, 2) from the process which is relatively probabilistic, complex and unpredictable. This paper is the 1st step of continuous research, to determine the necessary concept through critical review of the two methods, establish an outline of the new model, and simulation of a small virtual street network.

Stores along commercial streets display their information to the outside using their facades facing the street to attract pedestrians, who are potential customers. Pedestrians, who are visitors to the commercial area, are exploring stores to meet the purpose of their visit. During this process, pedestrians experience the city space. This paper proposes a methodology for the sequential analysis of a commercial street from the viewpoint of pedestrian movement based on business type, which might be the most important factor for the formation of the atmosphere of a certain street, and location relationships between the pedestrians and stores on a street. To construct a quantitative model, the distribution of stores was first divided into a certain unit considering the recognition distance of pedestrians. In a divided unit, the business type of each store was replaced with a different point source individually and stacked vertically according to the location inside the building. By calculating the sequential change in intensity of the point sources, a final analytical model was obtained as the standing point of pedestrian movement. For the case study, the developed model was applied to Jungangro and Myeongdong-gil in Myeongdong and verified that the difference in store influence on pedestrians depended on the width of the street or number of floors where the store was located.

Recently, gentrification has occurred not only in Seoul, the capital, but also nationwide in Korea. In other countries such as the United States and Europe, it occurs in various areas such as housing, commerce, and culture, but in Korea, it occurs in most commercial areas. In addition, the resulting social problems are also very serious, and the pace of occurrence and progress is also very fast. The present study was conducted on Korean cities, especially local cities where gentrification occurred due to the government’s urban regeneration project. A system was established to analyze the occurrence phenomenon from a supply perspective and a demand perspective, and to synthesize them to predict the stages that proceed when gentrification occurs by period. Through this, it will be possible to observe and predict gentrification phenomena and respond in advance.
