Conceptual design and prototypical practical testing of a mobility data trustee in the application field of automated driving using the Test Area Autonomous Driving Baden-Württemberg

In the TreuMoDa project, an independent and non-profit interface is being designed that enables data protection-compliant provision and use of data from the field of mobility by science, business, and society according to transparent criteria. The aim is to develop a concept for a mobility data trustee that is ready for application and to test the most important aspects in an exemplary manner. In this context, the business model, legal form, and financing options for the establishment of a neutral, independent, and sustainably financed data trustee are to be developed in cooperation with stakeholders. The requirements of the trustee's stakeholders from research, business, and public authorities are incorporated into the concept, as well as the legal, technical, and organizational requirements.

Data that is exchanged via a future Mobility Data Trustee is in the automated driving application field. Examples of focused data are:

• Vehicle data in the form of sensor data such as radar, camera, and lidar or position, velocity, and acceleration data Data on the operating behaviour of vehicle components
• Traffic flow data e.g., on the utilization of traffic routes
• Environmental data such as road conditions, buildings, and construction sites

The Mobility Data Trustee is intended to be a building block for strengthening science and innovation by opening the use and broad subsequent use of data. To this end, the trustee should offer services for the application-oriented anonymization of personal data and should support in the case of legal issues in the exchange of personal data. For example, after the collection of personal data in a research project, data could be exchanged anonymously and without loss of relevant information between consortium partners via the trustee.

The following figure shows the developed data exchange process between the actors data provider, trustee, and data user in the simplest form in the event of an anonymization request.
