National Transportation Communications for Intelligent Transportation System (ITS) Protocol (NTCIP) is a family of standards that provides both the rules for communicating (called protocols) and the vocabulary (called objects) necessary to allow electronic traffic control equipment from different manufacturers to operate with each other as a system.
NTCIP is the first set of standards for the transportation industry that allows traffic control systems to be built using a “mix and match” approach with equipment from different manufacturers. NTCIP standards reduce the need for reliance on specific equipment vendors and customized one-of-a-kind software. NTCIP is part of a larger effort to develop a family of ITS standards.
To assure both manufacturer and user community support, NTCIP is a joint product of the National Electrical Manufacturers Association (NEMA) teamed with the Institute of Transportation Engineers (ITE) and the American Association of State Highway and Transportation Officials (AASHTO). In 1996, NEMA, ITE, and AASHTO under a contract with what is now the USDOT Office of the Assistant Secretary for Research and Technology signed a Memorandum of Understanding (MOU) to initiate this effort. NTCIP continues to enjoy support from the U.S Department of Transportation. The original NTCIP Steering Group was reorganized to become the NTCIP Joint Committee.
