Just a couple of years ago the delineation between the public and the private sector was clear. However, with the introduction and proliferation of shared mobility providers, the boundary is becoming fuzzy, especially since these newcomers all use their own specific way of checking in and out. Because they are not incorporated into a single digital ecosystem, the journey from door to door is becoming less seamless the more mobility providers are added to the market. The goal of this thesis is to fully understand what exactly constitutes seamless mobility and how it can be incorporated into the Dutch mobility sector. Consolidating research presented in this thesis in combination with previous research, a full traveller journey map is constructed in which anti- seamless behaviour is identified. Checking in to both a train station gate and a shared modality are the least seamless aspects of the journey. Therefore a new novel seamless interaction idea is presented. The proposed interaction is essentially the inverse of the current situation revolving around the idea of a wireless digital handshake. Wherein the old scenario the traveller must physically present a modality-specific identifier to a permanently closed barrier i.e. gate or moped, a traveller now carries a small modality non-specific token which can be detected by a gate at the train station or by a parked shared modality if it is in close proximity. Check-in gates at the train station are now permanently open and subsequently will only close when a valid token is not detected i.e. the digital handshake cannot be made. The same goes for checking in on a shared modality. Shared modalities are permanently unlocked and turned on and will cut the power, apply the brakes, or sounds an alarm when a valid token is not detected i.e. the digital handshake cannot be made. The combination of the wireless technologies PKES and UWB are selected. The introduction of the aforementioned seamless mobility scenario is dependent on the integration of public transportation and shared mobility services. Based on interviews with a municipality, a shared mobility provider, desk research, and leveraging the future introduction of Account Based Ticketing, nine strategic interventions are proposed. Now made possible by the strategic blueprint, research is done on how future travellers will react to the reimagined seamless mobility scenario. This is done through a series of interaction prototyping tests. Insights are translated in a redesigned travel token, a seamless train station gate, and a seamless scooter. A demonstrator prototype is built for attendees at the thesis defence to experience the reimagined seamless travel scenario.
