Spatio-temporal trajectory analysis of mobile objectifs following the same itinerary by Laurent Etienne( )

2 editions published between 2010 and 2012 in English and held by 3 WorldCat member libraries worldwide

More and more mobile objects are now equipped with sensors allowing real time monitoring of their movements. Nowadays, the data produced by these sensors can be stored in spatio-temporal databases. The main goal of this article is to perform a data mining on a huge quantity of mobile object's positions moving in an open space in order to deduce its behaviour. New tools must be defined to ease the detection of outliers. First of all, a zone graph is set up in order to define itineraries. Then, trajectories of mobile objects following the same itinerary are extracted from the spatio-temporal database and clustered. A statistical analysis on this set of trajectories lead to spatio-temporal patterns such as the main route and spatio-temporal channel followed by most of trajectories of the set. Using these patterns, unusual situations can be detected. Furthermore, a mobile object's behaviour can be defined by comparing its positions with these spatio-temporal patterns. In this article, this technique is applied to ships' movements in an open maritime area. Unusual behaviours such as being ahead of schedule or delayed or veering to the left or to the right of the main route are detected. A case study illustrates these processes based on ships' positions recorded during two years around the Brest area. This method can be extended to almost all kinds of mobile objects (pedestrians, aircrafts, hurricanes, ...) moving in an open area
Motifs spatio-temporels de trajectoires d'objets mobiles, de l'extraction à la détection de comportements inhabituels : application au trafic maritime by Laurent Etienne( Book )

3 editions published in 2011 in French and held by 2 WorldCat member libraries worldwide

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 case maritime traffic monitoring

Outil d'aide aux décideurs concernant le suivi de navires : suivi de trajectoires relatives entre navires et détection de trajectoires inhabituelles by Laurent Etienne( )

1 edition published in 2008 in French and held by 1 WorldCat member library worldwide

Le suivi temps réel de navires, à l'aide de capteurs GPS et de systèmes de transmissions sans fil, est en plein essor. Ces systèmes sont employés essentiellement pour permettre la visualisation temps réel et de détecter les risques de collision. Aujourd'hui, la gestion par des bases de données d'objets mobiles, ouvre des perspectives inédites. En effet, les déplacements des objets peuvent alors être analysés sur des espaces et des durées importantes. Ces systèmes couplés aux bases de données, sont potentiellement des formidables outils d'aide à la décision en termes de surveillance du trafic
