SYSTEM ARCHITECTURE EFFORTS IN THE GARY-CHICAGO-MILWAUKEE CORRIDOR

The Gary-Chicago-Milwaukee (GCM) Corridor is one of four Priority Corridors throughout the country. These corridors were selected for special federal transportation funding based on very specific transportation and environmental criteria. One of the most significant efforts within the GCM Corridor is the Multi-Modal Traveler Information System (MMTIS). This effort is geared at providing a system for integrating Intelligent Transportation Systems (ITS), throughout the corridor. To support this effort, the MMTIS contract has produced the initial design and system architecture necessary for IDOT, and other GCM agencies, to build interoperable Advanced Traffic Management Systems (ATMS) and Advanced Traveler Information Systems throughout the GCM Corridor. In addition, there are at least six new multimillion dollar computer system projects in the GCM Corridor either currently underway, or beginning within the next two years. Parallel to these efforts, the United States Department of Transportation has recently invested millions of dollars in the development of a National ITS Architecture. This paper will discuss the work underway within the GCM Corridor and its relation to the National ITS Architecture efforts.
