Sejong Special Self-Governing City is a purpose-built administrative capital of South Korea, established in 2012 to decentralise government functions from Seoul. Its masterplan is designed as a smart city from the ground up, with integrated digital infrastructure, smart mobility corridors, and real-time city operating systems. Sejong’s population is growing rapidly and the city is designed to eventually host the majority of South Korea’s central government ministries.

Sejong Smart City is South Korea’s flagship national smart city project, designated as a testbed for Fourth Industrial Revolution technologies. Its strategy centres on a decentralised mobility-as-a-service (MaaS) ecosystem featuring autonomous shuttles, AI-powered traffic and energy management, a citizen data sovereignty platform, and a living-lab approach to public participation. Managed jointly by the Ministry of Land, Infrastructure and Transport, Sejong serves as South Korea’s primary smart city export model.
