We propose RoseTrajVis, a visual analytics system for studying commuting behaviours using classic rose diagrams, which, given a location in a map, aggregate trajectories by direction, show additional summary information, such as average speed bands, and allow the application of spatial-temporal filters. The rose diagrams also include colored arrows...

In this paper we present a system for analyzing tracks using graphics inspired in wind roses. The elements of the rose include petals that aggregate tracks given their direction and that also show their average speeds within an area around a point in a map, as well as arrows that point to the origin and destination of the tracks. The user can inter...
