%X The uncertainty management problem for moving objects databases has been studied recently,with many models and algorithms proposed. However,very limited work has dealt with the index of uncertain trajectories for a running moving objects database. In this paper,we propose a framework,UTR-Tree,for indexing the uncertain trajectories of network-constrained moving objects. By the support of UTR-Tree,the moving objects database can efficiently track and query not only the historical,but also the current and eve...
