One of the key research issues with moving objects databases is the uncertainty management. The uncertainty management for moving objects has been well studied recently, with many models and algorithms proposed. In this chapter, we analyze the uncertainty of moving objects in spatial networks and introduce an uncertain trajectory model and an index framework, the uncertain trajectory based Rtree (UTR-tree), for indexing the fully uncertain trajectories of network-constrained moving objects. Then, we introduce how to process queries on this framework. The content of this chapter is mainly from the work of Ding in [14].
