“…In this work, based on multiple trials, a temporal gap event means that between two consecutive observations a gap of 30 minutes or more is observed. The smoothT urn event means that the heading at a point (p i , t i ) has deviated from the mean heading of recent movement by an angle larger than a threshold, e.g., 10°, where the mean heading is calculated based on the k preceding points (here k=7), similar to [15]. We also introduce several events using speed ranges (in knots/hour): the stop event for speed range [0,1), the slowM otion event for speed range [1,5), then six events speed5to6, speed6to7, speed7to8, speed8to9, speed9to10, speed10P lus that are defined analogously.…”
