Urbanization is under way rapidly worldwide, and more people are expected to live in cities in the future. Along with urbanization, various urban problems are occurring such as traffic congestion, increase in crime, and environmental pollution, and people have begun to pursue a more convenient way of living by resolving the issues that cause inconveniences in their lives. Cities are transforming into sustainable “smart cities” where new urban services are provided by applying advanced technologies.

Unlike existing urban planning, smart cities have a vision of improving the quality of life by providing services using smart technologies. Accordingly, smart city projects can be conducted successfully by establishing and operating quality smart city services in smart cities. In Korea, public smart city services are mainstream, as they are mostly established through public projects. As a result, it is difficult to generate a profit, making it hard to secure expenses for operation and maintenance. In this case, the services cannot be provided in a sustainable way.
