Urban DTC for Creating Optimized Smart Cities Attentive to the Individual

Creating Smart Cities through Digital Twins▼Abstract

We describe our initiatives in creating smart
cities using digital twin (DT) technology. In
these Feature Articles on Urban DTC for
Creating Optimized Smart Cities Attentive to theIndividual, we first outline the concept of a
totally optimized smart city. We then describe avariety of services that use digitalized data andartificial intelligence (AI), an integrated platformthat achieves total optimization by interlinking
those services, examples of services that linkareas over a wide region, and the AI value
platform that makes it easy to provide suchcross-domain services.
