Abstract
Advances in wireless communications, positioning technology, and other
hardware technologies combine to enable a range of applications that use a
mobile users geo-spatial data to deliver online, location-enhanced services,
often referred to as location-based services. Assuming that the service users
are constrained to a transportation network, this paper develops data structures
that model road networks, the mobile users, and stationary objects of interest.
The proposed framework encompasses two supplementary road network
representations, namely a two-dimensional representation and a graph
representation. These capture aspects of the problem domain that are required in
order to support the querying that underlies the envisioned location-based
services.
