DatSim 2.0

Digital Mobility Twin Munich

What are we doing?

Creating a digital foundation for future-proof mobility

We are creating a digital basis for comprehensively mapping mobility in the metropolitan region and testing the effectiveness and safety of future measures before they are introduced. 

How do we do it?

Targeted Mmethod development and digital support for the MCube Cluster

We have two methodological focuses:

  1. Data collectionWe develop methods and infrastructure for the collection and provision of relevant mobility and traffic data. This includes existing data sets as well as precise, temporally and spatially high-resolution measurements of air quality and traffic.
  2. SimulationWe model traffic and emissions/immissions in the metropolitan region in order to digitally represent entire city districts realistically.

In order to further develop the methods in a targeted manner, we are working with two use cases: Together with municipal stakeholders, we are investigating the effects of mobility interventions on the urban emergency services and on traffic-related air quality.

The project also acts as a digital contact point for the MCube Cluster. We share our expertise, infrastructure and experience in the field of digitalization and modelling with other projects and actively support them in their implementation.

We test mobility offers in different steps

Scenario definition & requirements analysis

First, the study area and suitable corridors in Munich are defined. The spatial and temporal framework conditions are then defined. A concept for the simulation and visualization platform is then developed.

Data basis microscopic traffic simulation

In WP 1, the municipal traffic data is updated and expanded. A converter creates a simulation-capable representation of the road space.

The traffic simulation is created and calibrated with SUMO (open-source simulator) and integrated into the DatSim 2 software framework.

Microscopic traffic simulation

WP 2 focuses on the setup and calibration of microscopic traffic simulations for both ground-based and eVTOL (electric Vertical Take-Off and Landing aircraft) aircraft

An independent simulation environment for eVTOLs will be developed and the ground-based simulation will be validated with collected traffic data.

Data interfaces, data collection

While WP 1 creates the basis for the traffic simulation with static data, WP 3 collects dynamic traffic and environmental data to calibrate and validate the simulation environment from WP 2. WP 3 comprises the collection of air and traffic data as well as the methods and infrastructure for the collection and provision of relevant data sets, including high-resolution measurements.

Platform development

A cloud-based platform is being developed that coordinates data sources and simulation modules and integrates simulation results. This platform enables scalable links and traceable analyses. A common development environment is also provided.

Rescue modeling

WP 5 analyzes the influence of mobility innovations on the emergency services. Based on the fundamentals of microscopic traffic simulation and the implementation of eVTOLs, a digital image of Munich's emergency services will be created. Specialized routing procedures and new aviation concepts will be integrated in order to improve the rescue service.

Emission and dispersion modeling

WP 6 develops assessment metrics and combines these with influencing factors and control variables for urban air quality. This leads to microscopic emission and dispersion modeling. Finally, the results are validated and recommendations for action for future mobility scenarios are derived.

Who does it?

A motivated consortium of experienced partners from science, business, the public sector and society is working together in an interdisciplinary and transdisciplinary manner on the pressing issues of our time.
