The interoperability is the capacity of a system to work autonomously in different contexts, permitting the collaboration with other systems. To achieve this challenge it is necessary for the system to use a common context model. Therefore the context model is a key aspect of the ubiquitous system. In this work, a context model for public transport information system is explained; this model permits us to develop ubiquitous information services in a context of intermodal public transport networks. The main aspects of this context model are described: the ontology, the representation of the context entities and the main data involved. Using this model, ubiquitous information services, with a high level of functional scalability, context adaptability and accessibility, can be developed.
