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

Various visualization methods are available using the 3D city model which can improve the participation process for citizens and decision-makers. Concept studies or planned scenarios are migrated to the data schema of the Digital Twin Munich. These scenarios are then accessible in a local 3D scene together with the current situation. Depending on the presentation format it is possible to derive images, video animations, interactive 3D web applications or virtual reality (VR) panoramic tours. In the future, this result can be further developed by using specific visualization software (game engines) that can expand the range of implemented functions and professionalize the presentation through a photo-realistic visualization.

Contribution to the digitalization of municipal transport systems

The catchy and easy-to-understand 3D visualization simplifies participation processes for traffic infrastructure projects and significantly reduces the chance of misunderstanding the planned scenario. The effortless and fun to use interactive 3D web application, plus the immersive experience of a virtual reality application, allow a completely new kind of citizen participation.

Contribution to air pollution control / clean air in the City of Munich

Interactive 3D scenes and VR applications can be used to improve participation processes. This is particularly true for controversial traffic projects that are intended to reduce motorized traffic (e.g., improvement of cycling infrastructure). Resistance to projects, which contribute to air pollution reduction, could be significantly and quickly reduced.

Perspective of the action

The data of the 3D city model of the Digital Twin Munich allows the developed approach to be reproduced for any location within the City of Munich. The approach has been successfully tested using several project areas and is constantly being further developed. A project dashboard provides an interactive overview of the different local 3D scenes and project areas.
