Global smart spaces are intended to provide their inhabitants with
context-aware access to pervasive services and information relevant to large
geographical areas. Transportation is one obvious domain for such global smart
spaces since applications can be built to exploit the variety of sensor-rich
systems that have been deployed to support urban traffic control and highway
management as well as within individual vehicles. This paper presents a spatial
programming model designed to provide a standardised way to build contextaware
global smart space applications using information that is distributed
across independent (legacy, sensor-enabled, and embedded) systems by
exploiting the overlapping spatial and temporal attributes of the information
maintained by these systems. The spatial programming model is based on a
topographical approach to modelling space that enables systems to
independently define and use potentially overlapping spatial context in a
consistent manner and in contrast to topological approaches, in which
geographical relationships between objects are described explicitly. Moreover,
this approach facilitates the incremental construction of global smart spaces
since the underlying systems to be incorporated are largely decoupled. The
programming model has been evaluated by building a context-aware service for
multi-modal urban journey planning, as part of the development of an overall
architecture for intelligent transportation systems in Dublin.
