Pervasive Displays for Public Transport - An Overview of Ubiquitous Interactive Passenger Services

Useful and easy-to-use digital passenger services are one component for increasing the overall attractiveness of public transportation. In this paper, we provide an overview and a critical review of the current state of interactive passenger services through a case study involving mobile apps as well as situated public screens at two major stations. By relating the identified key features to prior research in the field, we identify trends and opportunities for impactful future research. We found that intermodal routing and ticketing in today's mobile apps are sophisticated, yet socializing features and interactive applications on public screens lag behind research in this field. Promising future research opportunities include improving personalization and investigating trust in public transportation and its digital services.
