This study examines and redefines the transportation policy directions for Seoul, focusing on the diagnosis of existing traffic management strategies and the establishment of new policy directions. The research analyzes major transportation policies implemented in Seoul from 2015 to 2024 and evaluates key initiatives within the city’s mid-term urban transportation improvement plan (2022-2026). Based on this evaluation, new policy directions are proposed, emphasizing "traffic efficiency," "traffic safety," and "citizen convenience," while also incorporating "sustainable eco-friendly approaches" and the "establishment of institutional foundations." In addition to existing initiatives, this study highlights the need for further focus on "technological innovation and development," "environmental sustainability," and "improvements in laws, institutions, and administration." A comprehensive roadmap is developed, offering short, medium, and long-term action plans for the improvement of traffic operations. Key recommendations include the advancement of smart signal systems using AI and big data, the introduction of an integrated mobility platform, the enhancement of safety for vulnerable road users through autonomous driving technologies, and the development of eco-friendly transport systems. The study emphasizes the importance of adapting to rapid social and technological changes through proactive policy formulation and administrative streamlining.
