Abstract
In this chapter, another application, a new moving objects database system, moving objects on dynamic transportation networks (MODTN), is proposed. In the MODTN system, moving objects are modeled as moving graph points that move only within predefined transportation networks. To express general events of the system, such as traffic jams, temporary constructions, insertion and deletion of junctions or routes, the underlying transportation networks are modeled as dynamic graphs so that the state and the topology of the graph system at any time instant can be tracked and queried. Besides, to track the location of network constrained moving objects, a location update mechanism is provided, and the corresponding uncertainty management issues are analyzed. The content of this chapter is mainly from the work of Ding in [1].
