Classification and Representation of Travel Information Service for Public Travel

Travel Information Service (TIS) system is an important component in Intelligent Transportation System(ITS). By studying the relationship between the three factors in traffic which means travelers, vehicles and roads, presents a new classification method of TIS for public travel, and transforms each type of service into common representation using XML (eXtensible Markup Language), so that the services can be defined and utilized in a generic approach and it can be understood by both person and computers. The classification and representation method in this paper can cover the public information demands during the whole period of travel course; furthermore it is advantage for the encapsulation and usage of service unit. The method is proved effectively in an experiment system.
