Discovery of stop regions for understanding repeat travel behaviors of moving objects
作者：
Highlights：
• Different from simplifying trajectories using turning points to keep their coarse shapes, this paper summarizes trajectories using stop points.
• We define a new concept of stay stability (i.e., reciprocal of speed) between any two GPS points to detect stop points on individual trajectories.
• We discover repeat travel behaviors by finding common sequences of stop regions where a certain number of objects visit with similar stop duration.
• The experiments on 20 labeled trajectories in Geolife demonstrated the semantic effect, accuracy and near linear efficiency of our method.
