Linking Multimodal Traveller Information Services for Transnational Journey Planning

There is a huge cross-border travel demand within the EU leading to hundred millions of cross-border trips every year. Notwithstanding the information demand for seamless journey planning and accurate and timely information on public transport, the provided traveller information is often limited in terms of the provided modes and in terms of its geographical coverage. The above mentioned deficiency is tackled by an international consortium of journey planner- and transport operators in the frame of the INTERREG project “LinkingDanube”. The goal is the brining information together from several existing regional services in order to enable journey planning that goes beyond the territory covered by the single systems and offers travellers seamless travel information provided in one integrated journey plan. In particular the objective is to develop a system architecture that enables that combination of services, which is addressed as “distributed journey planning” and an integration of the results. By developing and establishing a common interface (Open API) at each of the involved systems, the exchange of requests and results (not data) will be facilitated. The paper elaborates the service architecture and outlines the technical implementation.
