This study investigates the current management conditions of street facilities in Seoul and proposes systematic improvement strategies to enhance urban aesthetics and pedestrian safety. Despite the city's efforts to promote pedestrian-friendly environments, poorly maintained and visually intrusive street facilities continue to undermine the goals of initiatives such as “Walkable Seoul” and “Design Seoul.” Ten types of facilities with direct visual and safety implications were selected through expert consultation and field evaluation. Survey results from citizens and public officials revealed a high perceived importance of street facility management but low overall satisfaction, citing issues such as budget constraints, fragmented responsibilities, and lack of interagency collaboration. To address these challenges, the study developed an integrated maintenance framework that includes a management ledger system and complaint tracking. A 360-degree panoramic imaging technique was applied for field surveys, demonstrating high efficiency in facility mapping and condition assessment. Furthermore, a maintenance prioritization index was formulated using the Analytic Hierarchy Process (AHP), incorporating criteria such as importance, condition grade, and complaint frequency. A concept for a smart maintenance system was also proposed, integrating AI-based facility recognition and automated notification mechanisms.
The study concludes by recommending institutional reforms, including ordinance amendments to specify maintenance responsibilities, the expansion of monitoring programs, and the establishment of a dedicated maintenance coordination committee. These measures aim to enhance transparency, responsiveness, and the long-term sustainability of street facility management in Seoul.
