Title: A geographic information system prototype for archived data from intelligent transportation systems: A multidimensional analysis

Abstract: Knowledge and information are the basis of informed travel behavior. The foundation of individual choice in transportation decision-making is improved by the availability and robustness of traveler information. Historical information combined with new information contributes to the individual decision maker's mode, route, and travel time choices. Information systems known as Intelligent Transportation Systems (ITS) have evolved along with other technological advances to improve the availability of transportation system information to travelers. In-vehicle navigation systems (IVNS), variable message signs (VMS) and other technologies have the potential to help alleviate overall capacity problems and incident related capacity overloads on existing roadways, on transit systems, at airports and ports by disseminating better information to travelers.

By using dynamic traffic assignment (DTA) models populated with streams of real-time information from field devices, accurate and timely information can be broadcast to the traveling public via VMS, IVNS and other broadcast technologies. These concepts are part of the third generation of solutions to the transportation guidance and information dissemination problem. While generating data to send out to travelers in real time, ITS typically creates and stores valuable data in non-homogenous archive systems. This rich data source often goes unused, and is not typically accessed by analysts. This prototype suggests using Geographic Information Systems (GIS) as the perfect environment to convert ITS generated and archived data into a homogenous source for robust analysis.

Even though knowledge representation in ITS has been standardized to some degree and has been automated in transportation agencies for some time, an informal ontology of transportation information is still used for decision support. This work suggests a GIS prototype that will exploit existing industry data collection technologies, and apply sound Information Science (IS) principles to a growing transportation industry database problem. The prototype demonstrates a rational approach to applying those principals to the ITS data archiving and retrieval problem, with emphasis on the possibilities for data analysis. This work will aid in the development of ITS data sharing and analysis around the world.
