WEIGHTED TRAJECTORY SIMILARITY DETERMINATION BASED ON SUB-TRAJECTORY QUERYING

Querying trajectories is disclosed. A database of rich typical trajectories, which includes both position and attribute information for each of the typical trajectories, is created. Using a current trajectory of a node or a current position of the node, the database is queried for a rich typical trajectory that likely corresponds to the current or anticipated trajectory of the node. The database is searched by identifying candidate trajectories and determining a similarity score for each of the candidate trajectories. The best scoring candidate trajectory may be returned and logistics operations may be performed using the best scoring candidate trajectory.
