Abstract

In this paper, we propose an efficient signature-based indexing scheme for efficiently dealing with the trajectories of current moving objects on road networks. We show that our indexing scheme achieves much better trajectory retrieval performance than the existing trajectory indexing schemes, such as TB-tree, FNR-tree and MON-tree.
