38、 v02 was prepared by the NTCIP Ramp Meter Control Working Group, which is a subdivision of the Joint Committee on the NTCIP. The Joint Committee is organized under a Memorandum of Understanding among AASHTO, ITE, and (NEMA). The Joint Committee on the NTCIP consists of six representatives from each
39、of the standards organizations, and provides guidance for NTCIP development. At the time that NTCIP 1207 v02 was prepared, the following individuals were active members of the NTCIP RMC Working Group: Brian Simi (Chair) Sean Coughlin Terry Haukom W.L. Bud Kent Mark Fox Joerg Nu Rosenbohm Edmund Chan
40、g Glenn Massarano Jeff McRae Mark Morse Other individuals providing input to NTCIP 1207 v02 include: Blake Christie David Cordone John Haigwood Curtis Herrick Pete Marshall Tom Timcho Jeris White In addition to the many volunteer efforts, recognition is also given to those organizations which suppor
41、ted the efforts of the working group by providing comments and funding for NTCIP 1207 v02, including: Batelle California Department of Transportation (Caltrans) Minnesota Department of Transportation (MnDOT) Noblis Inc. (formerly known as Mitretek Inc.) Siemens (formerly known as Eagle Traffic Contr
42、ol Systems and Gardner Systems) Ministry of Transportation of Ontario (MTO) Telvent Farradyne Inc. (formerly known as PB Farradyne) Texas Transportation Institute (TTI) TransCore Inc. Washington State Department of Transportation (WSDOT) In addition to the many volunteer efforts, the U.S. Department
43、 of Transportation, Federal Highway Administration and Joint Program Office, provided funding assistance for the development of the NTCIP standards and associated documents. 2014 AASHTO / ITE / NEMA Do Not Copy Without Written Permission NTCIP 1207 v02.14 Page ii FOREWORD NTCIP 1207 v02 identifies a
44、nd defines how a management station may wish to interface with a field device to control and monitor RMC units. NTCIP 1207 v02 provides definitions of data elements for use within ramp meter control. The data is defined using the Simple Network Management Protocol (SNMP) object-type format as define
45、d in RFC 1212. NTCIP 1207 v02 defines requirements that are applicable to all NTCIP RMC units and also contains optional and conditional sections that are applicable to specific environments for which they are intended. NTCIP 1207 v02 contains two normative and three informative annexes: a) Annex A
46、is informative and contains the Operations Concept and basically the functional requirements of a RMC unit. b) Annex B is normative and contains the Profile Requirements List (PRL), which has also been referred to as a Profile Implementation Conformance Statement (PICS). The PRL table includes each
47、of the defined object definitions, their potential value ranges, an indication whether the object is a control, status, or database parameter, and a column allowing a user to enter project-specific information. Since 2007 when NTCIP 1207 v02 last underwent major revision, the organization and format
48、ting of the systems engineering content in 1200-series standards has evolved. The NTCIP 1207 v03 will present systems engineering content in the more complete and correct format. c) Annex C is informative and contains the object tree showing the major nodes of the RMC unit object structure within th
49、e Global object tree. d) Annex D does not currently contain any data. In future, this annex is intended to contain the test procedures for testing a device for conformance to NTCIP 1207 v02, which is designated as a Normative annex. e) Annex E is informative and contains all the changes that have been made between the prior version of NTCIP 1207 and NTCIP 1207 v02. NTCIP 1207 v02 is an NTCIP Data Dictionary Standard. Data Dictionary Standards provide definitions of data elements for use within NTCIP systems. NTCIP 1
