САЖЕТАК / ABSTRACT:

In recent years, the advanced usage of underground spaces has progressed, and facilities such as underground shopping arcades, stations, and walkways, have combined to form networks covering wide areas. Furthermore, cities have developed by connecting the basement levels of buildings to underground spaces, creating urban areas where above-ground, underground, indoor, and outdoor spaces, have all become interconnected. While urban areas  expect to see improvements in accessibility, complicated connections lead to issues such as maze.

In order to respond to these challenges, the Ministry of Land, Infrastructure, Transport and Tourism of Japan (MLIT) has created 3D foundation maps that combine information from above and below ground, through balancing 3D city models, BIM models, etc., and is developing and conducting proof-of-concept tests on navigation systems that use these maps, under the PLATEAU project creating digital twins of Japan cities promoted by MLIT. This paper introduces an overview of the project and the usefulness of digital twin technology for underground spaces.
