| Abstract(in English) | With the recent progress of spatial information technologies and communication technologies, it becomes easy to track trajectories of many moving objects in real-time. To use obtained moving object trajectories for the analysis and prediction, we need to accumulate given trajectory streams in an efficient and accurate manner. For this purpose, we propose a mobility histogram construction method based on the Markov chain model. The histogram is physically represented as a tree structure and represents movement patterns in multiple granularities. When a new trajectory sequence is obtained, it updates the histogram structure incrementally. We also evaluate processing time in middle-node contained counter for stationary state. |
