Integration of private and carsharing vehicles into intermodal travel information systems

In the last years, intermodal mobility platforms offering combinations of various modal types, like trains, buses, carsharing and ride sharing, have emerged. These platforms often also offer a smartphone-based door-to-door navigation and a sophisticated travel assistance. Unfortunately, these smartphone-based services cannot be used by the travelers as soon as they are driving a car themselves, e.g., a carsharing vehicle or their private car, due to road safety regulations. The driver is essentially disconnected from the service. In addition, modern cars have a lot of configuration options a driver might want to set up. This discourages using shared vehicles in an intermodal itinerary. In this work we identify use cases of how an integration of carsharing vehicles into intermodal travel information systems can enhance travel experience, introduce a system architecture to allow the necessary information exchange and present a preliminary prototype to demonstrate its technical feasibility.
