This study aims to explore the potential and limitations of utilizing digital out-of-home (DOOH) advertising as a medium for disaster information dissemination and, based on this, propose directions for establishing an integrated management system. Accordingly, this study focused on whether digital out-of-home advertising, installed in public spaces with high visibility and repetitive exposure characteristics, can function as a complementary medium for disaster communication. To this end, expert in-depth interviews were conducted to derive its role as a disaster information delivery medium, effective types of disaster information, suitable media and installation locations, institutional and operational limitations, and directions for establishing an integrated management system. Interview results revealed that digital outdoor advertising is recognized as a medium capable of effective information delivery during disasters due to its spatial-based nature, forced exposure, and real-time capability. It was particularly found suitable for conveying information requiring immediate recognition and action during natural and social disasters. Conversely, the absence of an integrated management system, insufficient legal basis, unclear operational responsibility, and limitations in the financial support structure were identified as major constraints. Therefore, to establish digital outdoor advertising as disaster communication infrastructure, we propose the establishment of an integrated management system, legal and institutional improvements, technological standardization, and the introduction of an operational model based on public-private cooperation.
