Compliance is a condition that exists when an item meets all of the requirements of an agency specification. Conformance is a conditi
24、on that exists when an item meets all of the mandatory requirements of a standard. go to page 5 How do you start conformance testing with system requirements? Before starting a testing program, a well-defined set of requirements is defined, against which the testing procedure or process is be compar
25、ed. Well defined requirements are needed to test for standards conformance. Testing verifies that an ITS device complies with requirements in an agency specification. go to page 7 How are standards, specifications, and test plans related?

A list of example test documentation from several agencies is included. go to page 22 What NTCIP test tools are available?

28、oint 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 Institute of Transportation Engineers (ITE), and the National Electrical Manufacturers Association (NEMA). The
29、Joint Committee on the NTCIP consists of six representatives from each of the standards organizations, and provides guidance for NTCIP development.

NTCIP 9012 v01 is not an NTCIP s
34、tandard and does not contain any normative text. The NTCIP TCA WG expects NTCIP 9012 v01 to be used by transportation agencies to assist them in developing their own testing program when purchasing and deploying NTCIP “compliant” devices and systems. NOTEThe term “compliant” was used in the precedin
35、g paragraph. NTCIP 9012 v01 discusses the issues of conformance to NTCIP standards and compliance with agency specifications (including project- specific requirements), and clarifies the differences. The following keywords apply to this document: NTCIP, testing For more information about NTCIP stand

42、A History In September 1996, an agreement was executed among AASHTO, ITE, and NEMA to jointly develop, approve, and maintain the NTCIP standards. In December 2001, the Joint Committee on the NTCIP formed the TCA WG to investigate issues surrounding conformance testing and develop testing and conform
43、ity assessment documentation. The TCA WG held its first meeting in October 2002. The TCA WG began development of NTCIP 9012 v01 in October 2003. The TCA WG also produced NTCIP 8007 v01, which promotes a consistent look and feel for testing documentation throughout the various NTCIP standards. Consis
44、tent test documentation enables the next published versions of NTCIP 1200-series standards, produced by various NTCIP working groups and based on NTCIP 8007 v01, to be used by anyone wishing to test an implementation of an NTCIP standard. NTCIP 8007 v01 contains valuable insights into the developmen
45、t of test cases and test procedures for verifying NTCIP conformance. NTCIP 8007 v01 can assist both agencies and manufacturers in developing their NTCIP test procedures, where the standards are silent, or by augmenting test procedures where ITS device requirements have been extended beyond the basic
46、 NTCIP functionality. Compatibility of Versions To distinguish NTCIP 9012 v01 (as published) from previous drafts, NTCIP 9012 v01 also includes NTCIP 9012 v01.27 on each page header. All NTCIP Standards Publications have a major and minor version number for configuration management. The version numb
47、er syntax is “v00.00a,“ with the major version number before the period, and the minor version number and edition letter (if any) after the period. NTCIP 9012 v01 is designated, and should be cited as, NTCIP 9012 v01. Anyone using NTCIP 9012 v01 should seek information about the version number that
48、is of interest to them in any given circumstance.
