Busan Metropolitan City Extends MOU with Korea Land and Geospatial Informatix Corporation (LX): Secures Exclusive Rights to “1365 Twin”

내용

Busan Metropolitan City (Mayor Park Heong-joon) announced that it will extend its Memorandum of Understanding (MOU) with Korea Land and Geospatial Informatix Corporation (LX), originally signed on May 22, 2023, by mutual agreement for an additional three years ahead of its expiration, in order to strengthen competitiveness in digital twin technology.

A digital twin refers to a digital replica that accurately reproduces objects or systems from the real world in a virtual environment, continuously reflecting and monitoring their status and changes through real-time data.

Based on the MOU signed with LX, a national institution specializing in digital twin technology, to enhance digital twin competitiveness, Busan Metropolitan City significantly contributed to being selected for the 2024 Digital Twin Pilot Zone Development Project.

As this year marks the final year of the Digital Twin Pilot Zone Project, the administrative and public service platforms developed through the project are currently operated on LX’s cloud servers. Both parties agreed to extend the MOU for three years to stabilize and advance a sustainable digital twin development model.

The city also plans to expand the use of digital twin technology beyond the pilot area of Busanjin-gu to the entire Busan region, ensuring not only the digital transformation of administrative services but also enabling all citizens to utilize digital twin technology.

Busan Metropolitan City has registered the service mark “1365 Twin,” the name of its public digital twin platform available at https://1365twin.busan.kr, thereby preventing commercial use and securing its public nature.

Meanwhile, in 2025 (the second year of the project), three specialized services—urban air quality management, smart emergency response for citizen safety, and urban artificial lighting safety services—were implemented and are available through the official website.

The Urban Air Quality Management Service installs mobile air quality IoT sensors on buses in Busan to measure resuspended dust (PM10, PM2.5) and volatile organic compounds (VOCs), and uses simulations to analyze how air pollutants disperse. This supports data-driven decision-making for operating specialized vehicles such as dust suction trucks and water spraying vehicles, and provides citizens with a “Outdoor Activity Air Quality Index (tentative)” to guide health-related activities.

The Smart Emergency Response Citizen Safety Service allows citizens to check the locations and detailed information of seven types of emergency facilities, including AEDs, in advance. It also provides analysis of coverage blind spots, optimal placement recommendations, 3D indoor and outdoor views, and the shortest routes.

The Urban Artificial Lighting Safety Service analyzes lighting environments using digital twin-based light impact heatmaps and virtual simulations, enabling the identification of areas requiring improvement by diagnosing hotspots of excessive lighting.

Baek Myeong-gi, Director General of the Urban Planning Bureau, stated, “We plan to revise and distribute manuals and use cases so that citizens can easily understand the concept of digital twins and conveniently utilize the services through the official website. We will also actively promote our achievements through various media to expand the Busan-style digital twin safety service model nationwide.”
