Abstract
This study investigated the characteristics of outdoor advertising in downtown streets where the local governments improved and maintained. The purpose of this study was to examine how they met outdoor advertising guidelines in the basic landscape plan and how they contributed to the improvement of urban landscape. The outdoor advertising improvement project of local governments has contributed to the formation of downtown street landscape. However, as outdoor advertising is increasingly occupied in the landscape, it becomes a factor that hinders the landscape. Moreover, as outdoor advertising aims at advertisement, unique outdoor advertising has appeared, which is not matched with the surroundings. Therefore, it is necessary to take complementary measures. This study is a basic study to investigate the characteristics of outdoor advertising improvement which is a key element of urban landscape formation. Therefore, further study should be conducted on how an improved street image is evaluated.
