Towards Delivering Context-Aware Transportation User Services

Abstract

ITS architectures encourage integration of individual intelligent transportation systems into comprehensive platforms and enable sharing of information across a wide variety of systems and services. This paper presents a spatial programming model that has been designed as part of the iTransIT ITS framework to provide a standardized way to build value-added transportation user services and ultimately to deliver contextual transportation information to users. The spatial programming model is based on a topographical approach to modeling space that enables services to use potentially overlapping spatial context to correlate independently defined distributed information. This programming model has been evaluated by building a context-aware service for multi-modal urban journey planning
