The present invention relates to a system and method for itinerary planning. The method commences with the population of a first queue with a first set of network segments connected to the origin. One of the network segments is removed from the first queue. An expansion build representing the one network segment removed from the input queue is placed together with a continuing network segment in a second queue if the continuing network segment has not been considered. A captured build representing the network segment removed from the input queue together with the continuing network segment in the first queue if the continuing network segment has been considered. The placing is repeated until the first queue is empty. The first queue is replaced with the builds in the second queue. The removing to the replacing is repeated until the first and second queues are empty. At least one of the builds having a lowest cost is outputted.
