Abstract : Mobile objects are now equipped with sensors allowing real time monitoring of their movements. Nowadays, the data produced by these sensors are received and stored in spatio-temporal databases in order to visually follow their movements. Data mining on this huge quantity of stored positions allows to extract the behaviour of these mobile objects (spatio-temporal patterns) and to analyze in real time trajectories of mobile objects following the same itinerary. Using these patterns, unusual situations can be detected. This research defines both spatio-temporel patterns and comparison tools to qualify trajectories using a similarity index based on spatial and temporal measures and fuzzy logic. These tools can be used to ease maritime traffic monitoring.
