In recent years, digital technologies such as ICT and AI have been tried and introduced in the fields of infrastructure construction and maintenance. To promote data-driven infrastructure management through the use of such digital technologies, it is important to develop an infrastructure data platform to manage the information. By utilizing this platform to realize a digital twin, it is expected to improve the productivity in infrastructure management and create added value. This paper describes the digital twin with infrastructure data platforms and examples of IoT and other technologies that support it, as well as the advancement of infrastructure management and future prospects through the use of digital technologies.
