Because moving objects usually move on spatial networks, their trajectories play an important role in indexing them for spatial network databases. In this paper, we propose a new signature-based indexing scheme for moving objects' trajectories on spatial networks. For this, we design it so that we can efficiently deal with the trajectories of current moving objects as well as for maintaining those of past moving objects. In addition, we provide both an insertion algorithm to store the segmentdoi:10.1007/978-3-540-69384-0_78 fatcat:lw6f6q45krg7jjcttukklqsyuy
