| Abstract |
The number of visitors to the COEX Mall decreased after remodeling in 2013 contrary to the prediction that the number would increase. After remodeling, visitors had inconvenience with using the mall and difficulties figuring out their locations or surroundings. They suffered problems with spatial cognition and wayfinding. This study set out to compare the spatial structure of the mall before and after remodeling and identify factors to influence visitors' spatial cognition. For methodology, the investigator employed axial map analysis and visual graph analysis(VGA) based on the space syntax theory and used integration and intelligibility as analysis indexes. The axial map analysis results show that the integration of the mall was higher before remodeling than after it. The level of integration was especially high at the main plaza, major anchor facilities and passages between them, which indicates that access to these spaces was high. These findings suggest that the utilization and access of the main plaza was high and that the availability of passages to the nearby plazas was high. The mall's intelligibility was lower after remodeling, which means that the overall spatial cognition of the mall dropped after remodeling. The VGA analysis results reveal that the integration of the mall was higher after remodeling. It was relatively high at the plazas, which indicates that access to the plaza spaces was high. After remodeling, the paths to the entrances, plazas, and major anchor facilities increased, which broadened the scope of path choice for visitors. Increased paths to space meant lower access to it. That is, a simpler path would increase access to space and thus visitors' spatial cognition. The study compared and analyzed the spatial structure of the mall before and after remodeling and found that decreased paths of action to the major anchor facilities led to fewer paths accessible by visitors and thus their increased access and spatial cognition. |
