Abstract
Simplification of trajectory representation is provided. Trajectories represented by a set of points on a map are obtained. Common route elements are identified for the trajectories based on the set of points. Each of the common route elements represents a geospatial area in which at least a predetermined number of the trajectories are identical. Simplified representations of the trajectories are generated based on the identified common route elements.
