National Transportation Communications for Intelligent Transportation System Protocol

[2] The protocol is the product of a joint standardization project guided by the Joint Committee on the NTCIP, which is composed of six representatives each from the National Electrical Manufacturers Association (NEMA), the American Association of State Highway and Transportation Officials (AASHTO), and the Institute of Transportation Engineers (ITE).

Since the NEMA Transportation Section members had already started work on a new industry standard, they offered to expedite and expand the scope of their activities.

In 1996, the FHWA suggested a partnership of standards developing organizations to expand both user and industry involvement.

The NTCIP Framework is based primarily on the open standards of the Internet Engineering Task Force (IETF), World Wide Web Consortium (W3C), and ISO, plus NTCIP data dictionary standards specific for the task of ITS device communications.
