Journey solution

It is a set of one or more commercial transport services answering at least the question ‘How can I go from location A to location B at a given departure/arrival date And time?’. The question could contain more complex additional criteria, such as ‘in the fastest way’, ‘in the cheapest way’, ‘with no changes’, etc. The passenger can build the journey solutions by him/herself, consulting different information sources, or the solution can be offered to him/her by a journey Planner
