Abstract :
The convergence of wireless communication, mobile positioning and geographic information system (GIS) has given rise to a new class of location based applications and services, which deliver real-time information to mobile users in accordance with their current locations. The mobile applications deal with tracking and management of mobile objects, and need to pose spatio-temporal queries. In this paper, we propose a data model of mobile object on a transportation network according to open OGC simple feature specification, and present a query language with a powerful set of predicates. We also give with the new emerging RT-UML specification an object oriented model of transportation information system (TIS) as a prototype to using the mobile object in a real-time context for location based services
