Mobility-as-a-Service (MaaS) consists in the integration of various forms of transport services into a single mobility service. The goal is to provide a traveler with the service needed for a door-to-door travel under a single payment whilst integrating disparate modes of mobility (public transport, car- or bike-sharing, taxi/car rental, or a combination thereof) under one travel experience. After years of conceptualization and strategizing, MaaS is becoming a present reality rather than a future goal. However, many challenges remain unanswered. The development of multimodal travel information, planning and booking services, and the interoperability between business applications is currently limited due to the fragmentation and incompatibility of interchange formats and protocols both within and across transport sectors. The technology known as RDF, Linked Data and the Semantic Web, proposes a framework to discuss the semantics of terms in a decentralized fashion on web-scale. As MaaS is decentralized by definition, this workshop targets researchers and practitioners that are contributing to transform the transportation sector by proposing new semantic-based solutions to achieve the MaaS objectives. The workshop is an opportunity for disseminating and discussing use cases and studies showing the application of semantic technologies in the Transport domain to tackle the above-mentioned challenges.


  • Modeling and knowledge representation in the Transport domain
  • Vocabularies and ontologies for the Transport domain
  • Semantic-based conversion of transportation data formats (e.g., GTFS, NeTEx/Transmodel)
  • Web APIs sharing Linked Open Transport data on web-scale
  • Transport payment solutions with Web standards
  • Semantic interoperability solutions for MaaS
  • Applications exploiting semantics in transport
  • User-based contributions to transport data, possibly enhanced by semantics
  • Semantic integration of transport data with other open city data
