- Recently, the LBS (Location-based services), which make use of location information of moving objects, have obtained increasingly high attention. We can store and manage the trajectories of moving objects such as vehicles by querying moving object database management system. Therefore, it may be used to deliver better services to users by past trajectory information. In this paper, we describe a novel method that determines an optimal route by querying the trajectory of moving objects stored in moving object database system. In general, the route determination algorithms are not proper in real world because these make use of only static properties of road segments. However, our approach can determine the optimal route using dynamic attributes such as passing time and real speed of road segments extracted from the trajectories of moving objects. So we can provide more optimal route than results of conventional route determination methods without traffic information gathering devices. © Springer-Verlag Berlin Heidelberg 2006.
