This paper proposes workload-aware Adaptive OcTree based Trajectory clustering Index (ATTI) aiming at optimizing trajectory storage and index performance. The contributions are three-folds.  ...  based on GPS update workload; Third, the query workload adaptive mechanism is proposed based on virtual OcTree forest.  ...  Query Adaptive Virtual Forest Impact of Query Size to Index Workload-aware OcTree can dynamically adjust its structure according to the changing of workload.  ...
