Smart Cities could not be realized without envisioning a change towards the Mobility-as-a-Service (MaaS) paradigm for integrated and intelligent transportation. MaaS improves every aspect of transportation from ticketing to navigation, from traffic to parking management and from car/bike sharing to door-to-door travel. However, to make MaaS a reality, challenges in data integration must be addressed. The development of multimodal travel information, planning and booking services, and the interoperability between business applications are currently limited due to the fragmentation and incompatibility of interchange formats and protocols both within and across transport sectors. This workshop seeks to advance MaaS through Semantic Web, Linked Data and Knowledge Graph techniques. In-scope are methods to query and reason over integrated data on the web that can help an end-user to plan and book a trip from A to B. We target researchers and practitioners who are contributing to the transformation of the transportation sector by proposing new solutions based on semantic techniques and technologies, to realize MaaS objectives. The workshop is an opportunity for disseminating and discussing use cases and studies showing the application of semantic and web technologies in the transport domain to tackle the aforementioned challenges.
