45、the naming service for CORBA for use in center-to-center communications in the transportation domain, as well as other environments that reference NTCIP 1104 v01. NTCIP 1104 v01 defines requirements that are applicable to NTCIP environments that use CORBA and any other environments that reference NT
46、CIP 1104 v01. The following keywords apply to NTCIP 1104 v01: AASHTO, ITE, NEMA, NTCIP, CORBA. In 1992, the NEMA 3-TS Transportation Management Systems and Associated Control Devices Section began development of the NTCIP. The Transportation Sections purpose was in response to user needs to include
47、standardized systems communication in the NEMA TS 2 standard, Traffic Controller Assemblies. Under the guidance of the Federal Highway Administrations NTCIP Steering Group, the NEMA effort was expanded to include the development of communications standards for all transportation field devices that c
48、ould be used in an Intelligent Transportation Systems (ITS) network. In September 1996, an agreement was executed among AASHTO, ITE, and NEMA to jointly develop, approve, and maintain the NTCIP standards. The Joint Committee on the NTCIP formed the NTCIP Center-to-Center Working Group to develop cen
49、ter-to-center protocol standards. The NTCIP Center-to-Center Working Groups first meeting was in July 1996. In May 2000, the Joint Committee approved the work item to draft a CORBA naming specification.
