Results of the funding project Digital Twin Munich (DT-M)

The Federal Ministry for Digital and Transport supports measures for the digital transformation of urban mobility in German cities and municipalities. With the nationwide funding guideline "Digitalization of municipal transport systems", the federal government is making an important contribution to climate and health protection in Germany. Within this context the funding project "Digital Twin of the City of Munich to improve the spatial database for traffic planning and control measures with the overarching goal of air quality improvement" was conducted in Munich.

In 2018, the groundwork for the Digital Twin Munich was laid. The GeodataService (Department of Communal Services) was granted funding for the Digital Twin Munich. The funding project commenced on January 1, 2019.

The idea of a Digital Twin is not new, but Munich is one of the first cities to successfully implement this approach for urban development. The funding project establishes essential foundations and implements numerous results. On December, 31, 2023, the funding project was successfully completed.

During the funding project, the Munich City Council decided on December 16, 2020, to institutionalize the Digital Twin as a permanent project. This decision was made within the framework of Munich's goal to achieve climate neutrality by 2025. Since then, the Digital Twin Munich has become the digital infrastructure of the climate-neutral city.

These results are described in detail:

Public Participation with the 3D City Model

Enhancing citizen participation by visualizing future scenarios using the 3D city model of the Digital Twin Munich.

3D Visualization and Standardized Representation of the Lane-Model

The standardized 3D modelling of roads and the street space enables its use for numerous applications and visualizations.

Indicator-based Analysis based on the 3D City Model

Indicators derived from the Digital Twin Munich allow the evaluation and comparison of “what-if scenarios”.

City-wide lane model: lane-exact representation of the road space

The lane model contains the entire road system of Munich in a simulation-enabled data structure.

Development of a city-wide network for control points

In order to integrate road traffic into the digital twin, high-precision measurement control points are required.

The Digital Twin Munich in Minecraft

Including the Digital Twin Munich as part of the Minecraft game provides a great opportunity to involve young people in participation and planning processes.

Modeling of Traffic-Related Air Pollution

The combination of multiple data sources enables the modeling of traffic-related air pollution.

Drone flights to survey and update the Digital Twin Munich

Drone-based data collection is suitable for capturing temporary and shot term or structural changes within the city and updating the city-wide data of the Digital Twin Munich.

Mapping Bike – area-specific update of the streetscape and supporting for drone flights

The concept of the mapping bike was developed in collaboration with the Technical University of Munich (TUM) to record changes in road construction and to complement drone-based data collection.
