  • The purpose of this study is to propose a spatial network reproduction method based on 'integration of bus stop network into existing spatial network' for urban spatial analysis and to verify its effectiveness. To achieve this goal, first, a method of integrating a spatial network based on a 'bus stop network' with an existing 'street network' and a 'integration of subway network into street network' based spatial network was proposed. Next, in order to verify the effectiveness of the spatial networks based on the 'integration of bus stop network into street network' and 'integrated bus stop network, street network and subway network', a correlation analysis between the space syntax analysis result of Seoul and the actual floating population was conducted. As a result of the analysis, the correlation value of 'integration of bus stop network into street network' was slightly higher than that of existing 'street network', and 'integrated bus stop network, street network and subway network' showed a little lower correlation value compared to existing 'integration of street network into subway network'. In conclusion, when the space syntax is applied to urban spatial analysis, the "bus stop network" implies that there is a limit to improving the performance of the spatial analysis model.

  • In this study, the effects of the construction of Gwangju-Jeonnam Innovation City were examined on the existing urban context around the city in the respect of urban spatial structure, and improvement directions of the broader region of Gwangju and Naju were discussed. Focusing on the wide-range region from Gwangju Metropolitan City to Naju City including the innovative city, comparative analyses were conducted of the wide-range spatial structures before and after construction of the innovative city using Primal Spatial Network-based Spatial Analysis. As a result, it was found that Gwangju-Jeonnam Innovative City had more influence on Gwangju Metropolitan City, than Naju City. After construction of the innovative city, Gwangju City showed clear differentiation of accessibility and centrality by region. The centrality has moved to the southern areas of Gwangsan-gu and Nam-gu, and accessibility has increased on the arterial roads connecting the innovative city and Gwangju. However, the accessibility of those roads did not spread to urban cores. Rather, it was found that the accessibility was lowered on the second ring road and the arterial roads connected to it, and the centrality in the urban cores was lowered than before construction of the innovative city. In this regard, Gwangju Metropolitan City is expected to increase the likelihood of development in the outskirts of the city, which is a boundary area with Naju, due to the innovative city. While it is expected that the centrality of the urban cores is shifting, and some urban cores will decline or even become hollow. Moreover, the phenomenon of decline of the old urban core is more concerned than other regions in that the centrality of the old urban core has already begun to decrease before the construction of the innovative city.
