摘要：	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 (TIS) which is being led by the Illinois Department of Transportation (IDOT). Parsons Transportation Group is assisting IDOT in their work. The Gateway is one of the largest, most complex TIS ever implemented. It 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. It also includes provision for joint control of field devices across jurisdictional boundaries. In implementing the Gateway, several issues needed to be addressed, many of which have national significance. This paper presents an overview of these issues and details the actions taken to mitigate the effect of these issues. Among the issues discussed are the results of the Corridor’s efforts to exchange geographically based data across several different databases. This is a necessity if information is to be transmitted electronically from computer to computer without any operator intervention. Currently, there are at least eight different location referencing systems in use within the Corridor. The Gateway is not the only system in the US facing this problem, and as a result, a national Location Referencing Messaging System (LRMS) developed by Oak Ridge Laboratory under a contract with the Federal Highway Administration has been implemented in the Corridor. Other issues addressed in this paper include: the need to be NTCIP compliant, specifically what is meant by this; how the design accommodates changes in National Transportation Communication for ITS Protocol (NTCIP); and what is considered as the baseline for NTCIP compliance. Additional issues addressed include: data fusion/verification; consensus building amongst diverse participants and procurement difficulties.
