7、S This publication was prepared by the NTCIP Dynamic Message Sign Working Group, a subdivision of the Joint Committee on the NTCIP. The Joint Committee is organized under a Memorandum of Understanding among the American Association of State Highway and Transportation Officials (AASHTO), the Institut
8、e of Transportation Engineers (ITE), and the National Electrical Manufacturers Association (NEMA). The NTCIP development effort is guided by the Joint Committee on the NTCIP, which consists of six representatives from each of the above organizations. At the time that this document was prepared, the
9、following individuals were active members of the NTCIP Dynamic Message Sign Working Group: Kenneth Bare Bob Blasi Joseph Graf Al Greist Pat Mulllins Graham Nicholls Joerg “Nu” Rosenbohm Ken Vaughn Other individuals providing input to the document, include: Brian Cronin Bob DeRoche Jeff McRae In addi
10、tion to the many volunteer efforts, recognition is also given to those organizations who supported the efforts of the working groups by providing comments and funding for the standard, including: ADDCO Manufacturing Co.

The data is defined using the Simple Network Management Protocol (SNMP) object-type
14、format as defined in RFC 1212 and would typically be exchanged using one of the NTCIP recognized Application Layers (e.g., SNMP). The content of one object, the dmsMessageMultiString object, uses a complex syntax called the Mark-Up Language for Transportation Information (MULTI) format. This format
15、is also defined in this standard. This standard defines requirements that are applicable to all NTCIP environments and it also contains optional and conditional clauses that are applicable to specific environments for which they are intended. The following keywords apply to this document: AASHTO, IT
16、E, NEMA, NTCIP, DMS, VMS, CMS, data, data dictionary, object, message sign, sign, MULTI. The effort to develop NTCIP began in 1992 with the 3-TS Transportation Management Systems and Associated Control Devices Section of NEMA. Their original desire was to address a user need for extending the TS 2 S
17、tandard for traffic control hardware to include standardized systems communication. Under the guidance of the Federal Highway Administrations (FHWA) NTCIP Steering Group, the NEMA effort was expanded to include the development of communications standards for all transportation field devices that cou
18、ld be used in an Intelligent Transportation Systems (ITS) network. Message signs were identified as one of the highest priority expansion areas. As a result, in August 1995, NEMA created the DMS Technical Subcommittee to standardize DMS equipment. Their first task was the development of this documen
19、t. In September 1996, a formal agreement was reached among NEMA, ITE, and AASHTO to jointly develop, approve, and maintain NTCIP Standards. One of the first tasks of this joint effort was to finalize the work that NEMA had already begun on the object definitions for dynamic message signs. 1999 AASHT
