Moving Objects Data Model Based on Multi-Scale Road Networks

Multi-scale, Road Networks, Moving Objects, Data Model

Data management for moving objects on road networks has become a hot topic research recently years. Moving objects have different running characteristics in different scales of road networks, but existing data models on moving objects haven't consider multi-scale characteristics in road networks. The concepts such as multi-scale moving objects trajectories, multi-scale moving objects locations are defined in the paper. This paper presents moving objects data model based on multi-scale road networks, and realizes representation for moving objects in multi-scale road networks.
