Design and implementation of an intermodal trip planner

The introduction and high usage of mobile devices in the last decade has encouraged the development of applications to assist travellers in the planning and completion of their journeys, and providing them with directions to get them to their destination as quickly as possible. However, the majority of these journey planners focus on generating trips that utilise either public transport or private vehicle for the entirety of the journey, but not both together. This paper presents details on the design and implementation of an intermodal trip planner for South-East Queensland that produces integrated journey plans that combine private automobile legs and public transport legs via the use of park'n'ride facilities. The method proposed for searching through these two different networks allows for the tailoring of search algorithms to the specific networks, as well as minimising the overall search space and the visits to a node as much as possible.
