New mobility solutions (NMS), such as car sharing, city bikes or e-scooters, have become increasingly popular in large cities. NMS have started to affect the way how people move in urban areas, but they can also be expected to affect public transportation companies and in particular their IT-landscape. The purpose of this paper is to investigate this topic from an enterprise architecture (EA) perspective. The purpose of our research is to contribute to this field by investigating the relevance of the topic from a business perspective. The main contribution of our work is (a) a literature analysis of EA use in public transportation and for NMS integration, (b) results from expert interviews investigating the business perspective from inside a large regional transportation organization and (c) the analysis of problems of NMS integration into EA.
