Abstract [en]

 Mobile applications and real-time data are excellent tools for rapidly sharing information. Such information may concern public transportation, such as time tables and traffic delays. This project has involved the development of a trip planner, which can subscribe to real-time data in order to inform the end user about the position of transit vehicles and trip updates. A trip planner is an application which, after having been given a start and a destination by the user, generates the possible trip between these two locations. The route is displayed upon a map, along with information of how the trip is travelled. The real-time data, which is pushed to the application, will inform the user if vehicles are delayed and if the trip needs to be updated due to a missed bus or train.

The trip planner for Itract developed in this project is using the graphical interface and some necessary Java classes from the open source application Open Trip Planner. The new trip planner, developed in this project, is compatible with the API of Itract, has some additional functionality and can subscribe to real-time information. To subscribe to real-time information, a database called Redis has been set up in connection to Itract. Another database, known as MongoDB, is used for persistant storage.
