Mobilitätsplattform – Reallabor Hamburg

Data Interaction
and Sovereignty

Key Question

How can cross-regional mobility services be technically bundled in such a way that people can use new and simplified travel options?

How can this be achieved?

In a pilot project, a door-to-door travel service between Hamburg and Berlin will be implemented, taking into account the IDS / GAIA-X data sovereignty standard.

Starting Point

In order to exploit the potential of intermodal travel, bundling all mobility offerings in one app is crucial. This application requires an exchange of data between the mobility providers of the various platforms, who have so far hardly been willing to share their data, also for fear of competitive disadvantages.


A data room mobility (DRM) enables different actors to exchange data and still maintain their data sovereignty. Similar to the telephone network, a network for secure data exchange is created between all participants who commit themselves to a certain membership behavior.

Based on the IDS standard (International Data Spaces under the auspices of the Fraunhofer-Gesellschaft), the following components are to be developed:

  1. A so-called demonstrator with user interface for an intermodal travel application as a plug-and-play module for existing apps (B2B).
  2. An IDS-based data link layer as a prototypical mobility data space.
  3. New value-added data services to link the app with the data space.


Business Model Variants
Various business model variants will be developed and compared in order to be able to develop the demonstrator envisaged in the project into a marketable product in a timely manner after the end of the project. The development will be carried out in 2 iterations.
Milestone 2: Design of Application (App) with Connection Layer
By linking existing mobility offerings, according to GAIA-X and IDSA principles, an app is developed that also functions nationwide or even pan-European and offers networked mobility.
Milestone 3: Extension of the Connectivity Layer for Mobility
Adapt and complement the IDS approach to take into account the specific requirements of the mobility sector, including local public transport, micro-mobility services such as e-scooters as well as on-demand / autonomous shuttles.
Milestone 4: Advanced Smart Mobility Demonstrator
The results will be used as a demonstrator on the potential feasibility of the project.

Demonstrator Data Space Mobility for the Use Case “Intermodal Travel”.

All mobility services are bundled and networked in a single application. Users benefit from a central app as a clear starting point for trip planning and booking. This creates flexible and personalized door-to-door mobility that opens up options beyond private motorized transport and can thus reduce CO 2 emissions. In addition, the open European standard allows providers to share their data securely and integrate it cost-effectively into their apps.
