Mining GPS trajectories of moving vehicles has led to many research directions, such as traffic modeling and driving predication. An important challenge is how to map GPS traces to a road network accurately under noisy conditions. However, to the best of our knowledge, there is no existing work that first simplifies a trajectory to improve map matching. In this paper we propose three trajectory simplification algorithms that can deal with both offline and online trajectory data. We use… CONTINUE READING
