VERSION v01 -- In 1998, AASHTO, ITE, and NEMA jointly approved NTCIP 1204 v01, which was previously numbered TS_3.7-1998. In 2002, the printed version of the Joint Standards Publication NTCIP 1204:1998 was available for order. NTCIP 1204:1998 was version v01.13, dated November 2001. The printed version included the Amendment 1 v02 revisions. In 2003 to 2004, the SDOs approved several one-year extensions for 1204:1998, beyond the five year expiration, while 1204 v02 was being drafted.

AMENDMENT 1 -- In 1998 and 1999, the ESS WG developed 1204 Amendment 1 to respond to user comments. Amendment 1 was jointly approved in January 2001. NTCIP 1204 v01.12, and subsequent versions, included the Amendment 1 text.

VERSION v02 -- Between 2002 and 2004, the NTCIP ESS WG worked at revising 1204, to include new sections for a concept of operations, functional requirements, dialogs, updated object definitions, a Protocol Requirements List, and a Requirements Traceability Matrix.

In 2005, the Joint Committee accepted 1204 v02.22 as a Recommended Standard. In April 2006, 1204 v02 was Jointly Approved. In May 2008, the published NTCIP 1204 version v02.24r was available as a PDF download. In 2009, the hardcopy v02.24p was available for order.

VERSION v03 -- This major version revision included the Annex C "Test Procedures." Annex C includes a definition of keywords, a table tracing Requirments to Test Cases, and test procedures for each test case. Adding the test procedures identified other changes, which are summarized in Annex D, Documentation of Revisions.

In June 2007, Bulletin B0121 issued v03.03c as a User Comment Draft for review and comment. In January 2008, the Joint Committee accepted 1204 v03.07 as a Recommended Standard, and Bulletin B0127 issued v03.07b for ballot and approval. In October 2008, 1204 v03 was Jointly Approved.
