“Get off your car!”: studying the user requirements of in-vehicle intermodal routing services

by Peter Fröhlich, Matthias Baldauf, Stefan Suette, Dietmar Schabus, Ulrich Lehner, Marko Jandrisits, Alexander Paier
Abstract:
Traffic information from diverse transportation domains is increasingly becoming interlinked and accessible in real-time. Upcoming intermodal transportation services could advise drivers to change to a public transportation means, especially in case of severe congestions on the road. We present a road user study with 52 participants with an in-car intermodal routing prototype that gained first empirical evidence on the user requirements in such scenarios. We found that a considerable number of recommendations for modal shifts to public transit were actually accepted by the drivers. In-car inquiry results highlight that decision-making under such complex time-constrained conditions needs to be supported by a considerable amount of updated, detailed and valid information about time savings, pricing, connections and also the actual route situation ahead. We show that the presentation of such large amounts of information should be feasible without categorical safety losses, even with small- screen devices (such as smartphones). To guide further development, related design experiences with regard to presentation modality, system input, and screen design are shared.
