    abstract     = "Traffic guidance is a major problem in the modern society. Traffic should be guided through city centers and other areas without queues forming on the roads. In this project a traffic guidance system is developed that gathers traffic data from the Android-based smartphones of car drivers, and use this to direct them away from heavily congested roads. It achieves this, by combining a more conventional {GPS-}based navigation app with positional feedback from the smartphone. The system consists of a internet based server, which handles the pathfinding and traffic control, using the A* algorithm and map data from OpenStreetMap, and an android app that guides the user and provide the feedback to the server. Also, a dummy client simulator is developed as well as a visualization tool, that simplifies testing and demonstrates the system functionality. We succeeded in developing a system that can guide car drivers along the fastest routes and re-route if necessary when traffic jams are forming."
