In recent years, not only has big data enabled the collection of information about social infrastructure services but the spread of IoT (Internet of Things) has been steadily realizing bidirectional services between users of services and providers. Urban design is expected to be innovated by efficiently utilizing technologies postulating bidirectionality composed of soft infrastructure, which is based on sharing economies such as car sharing. An information infrastructure utilizing various types of big data is one of the necessary elements for such innovative urban design and must be applied to the management and evaluation of diverse policies and services relating to residents and their activity areas. In this way, the following can be evaluated and managed:
- Evaluation of QoL in diverse segmentations.
- Evaluation of bidirectional services with fast data cycles.
- Knowledge sharing among stakeholders.
