VERSION v01 -- The NTCIP C2C WG developed the draft NTCIP 2306 between 2004 and 2006. In March 2005, the Joint Committee on the NTCIP accepted v01.51 as a User Comment Draft, and Standards Bulletin B0101 requested review and comment. In December 2005, NTCIP 2306 was proposed for acceptance as a Recommended Standard. After additional comments were received and addressed, the JC accepted v01.68 as a Recommended Standard in March 2006. In December 2006, v01.68b was sent to the SDOs for ballot and approval.

Approvals -- NTCIP 2306 v01 was approved by AASHTO in March 2008; approved by ITE in March 2008; and approved by NEMA in June 2007. In March 2008, NTCIP 2306 v01 was Jointly Approved.

XML SCHEMA and XDS FILE -- The "NTCIP-references.xsd" file contains a list of references from the AASHTO/ITE TMDD to the MIB objects of NTCIP. As of 2009, there was a "NTCIP-references.xsd" file on ITE's TMDD web site, The TMDD XML Schema and WSDL are listed under "Step No. 14" on the page, in the list item that reads "Zip File Containing the XML Schema and WSDL in XML Format." The NTCIP family of standards publications does not have XML schema representation of the MIB objects. [Manny Insignares, em091124]


As of 2008, no revisions are planned for NTCIP 2306 v01.
