As one of the four priority corridors originally established by the US Congress under the ISTEA legislation, the Gary-Chicago-Milwaukee (GCM) Corridor has been the scene of numerous ITS projects. One of the largest and most complex is the Gateway Traveler Information System. The Gateway involves the collection of transportation related data within a three state area and distribution of this data back to the sources as well as to the public and information service providers. Among the issues discussed are the results of the Corridor's efforts to exchange geographically based data; the need to be NTCIP compliant; how the design accommodates changes in National Transportation Communication for ITS Protocol (NTCIP); data fusion/verification; the role/interface to the media and information service providers; historical data storage; coordination of software efforts between the agencies; and determining compliance with the National ITS Architecture efforts.
