BACKGROUND -- The NTCIP 1202 was developed to be a Joint AASHTO / ITE / NEMA Standards Publication, as a Device Data Dictionary in the 1200-series of NTCIP document numbers. NTCIP 1202 defines the data elements and conformance requirements for actuated traffic signal controllers (ASC). The version v01 was published as NEMA TS 3.5-1996. Version v02 was developed to reflect lessons learned, to update the document format, and to add new features.

VERSION v01 HISTORY -- In 1996 and 1997, AASHTO, ITE, and NEMA balloted and approved the Recommended Standard TS_3.5-1996. In 1997, the printed version of the Joint Standards Publication NTCIP 1202:1996 was available.

AMENDMENT 01 HISTORY -- In November 1999, the Joint Committee accepted NTCIP 1202 Amendment 1 as a User Comment Draft Amendment. In April 2000, NTCIP Standards Bulletin B0049 sent NTCIP 1202 Amendment 1 v01.06b for user comment. After incorporation into 1202v02, Amendment 1 v06 was not advanced further.

VERSION v02 HISTORY -- In Spring 2001, NTCIP 1202 v02.10 was a working group draft, and included: all revisions noted in 1202 Amendment 1, clarifications based on user comments, and enhancements based on Joint Committee input. The major enhancement was the definition of 'block objects' to enable a more efficient upload / download of parameters. In June 2001, the Joint Committee accepted 1202 version 02 as a User Comment Draft. In February 2002, NTCIP Standards Bulletin B0068 sent 1202 v02.13 out for User Comment. In October 2002, the Joint Committee accepted 1202 v02.16 as a Recommended Standard. In April 2004, NTCIP Standards Bulletin B0091 sent 1202 v02.18 for balloting and approval. The USER COMMENT REPORT for 1202 v02 is posted in the Forum >> Standards >> 1202. As of March 2005, NTCIP 1202 v02 was Jointly Approved.
