The GCM Gateway TIS is currently being developed as the central traveler information hub for the Gary-Chicago-Milwaukee Corridor and will be operational this fall to replace an existing legacy system. The Gateway TIS collects transportation related information from geographically widely distributed agencies of varied natures validates and fuses the information collected, and disseminates it to interested public and private entities and the general public via Internet and intranet. This paper presents at a high level the CORBA based system architecture design of the Gateway system primarily from the perspective of ITS Center-to-Center interoperability. It also introduces the object oriented Gateway external data model that is specified in CORBA IDL (Interface Definition Language) and the Gateway Publisher/Subscriber based message oriented middleware for data collection and distribution. In addition, the Gateways decision on the selection of object oriented DBMS (Database Management System) versus relational DBMS is also discussed
