About the RadAR+ project

Mobility takes the form of everyday and supply mobility, as leisure, trade fair and tourist traffic as well as in the multi-layered economic movements of companies and service providers. Mobility is a basic need and, in addition to participation in public life, also ensures people can access their workplace, i.e. participate in economic life.
The combination of different modes of transport increases the complexity of the journey. Critical situations and delays in the travel chain occur on a regular basis, especially at heavily frequented and unknown interchanges. This is where currently available technical solutions reach their limits.
As part of the Federal Ministry of Education and Research (BMBF)’s funding measure “Adaptive, Learning Systems”, the research project RadAR+ has therefore developed an adaptive, learning mobility agent for the Frankfurt am Main area (demonstrator) that supports users during cognitively and physically challenging transport changes and adapts to their needs.

Equipping mobile devices such as smart glasses with augmented reality apps and an intuitive user model allows for individualised and needs-based support. The combination of remote and indoor routing ensures that travellers only receive relevant information. The entire travel chain was mapped out using the demonstrator they had developed.

The RadAR+ project has provided important insights for considering ethical, legal and social implications in the development of adaptive-learning systems. Relevant findings were be generated thanks to the systematic use of scientific concepts (Design‐for‐All), the exploratory use of methods and an exchange of knowledge with ELSI (Ethical, Legal and Social Implications) experts.


Project management at HOLM GmbH

HOLM GmbH was responsible for managing the overall project and also for the interface function between the project partners and other stakeholders. HOLM GmbH also organised and coordinated a central advisory interface for the project, what was known as the ELSI Advisory Board. The aim was to develop a concept that takes into account data protection aspects and is published as an ELSI Code of Conduct.
