Abstract: A method of generating an itinerary using a computer is provided. The itinerary includes nodes that represent a location serviced by scheduled transport services. A specification including a plurality of nodes is received. The specification may be in a specified order. An itinerary is then determined where a first fare is calculated that omits a node in the plurality of nodes received. A second fare is then calculated that includes the node omitted in the first fare. Thus, an itinerary that includes fares for each of the plurality of nodes is calculated; however, a fare is calculated that does not include a node in the plurality of nodes and thus does not adhere to the specified ordering of the plurality of nodes received.
