AASHTO, ITE, AND NEMA Release NTCIP 1211 v01 Object Definitions for Signal Control and Prioritization

Press release date: Oct 28, 2008

ROSSLYN, VA, October 28, 2008-The National Electrical Manufacturers Association (NEMA), the American Association of State Highway and Transportation Officials (AASHTO), and the Institute of Transportation Engineers (ITE) have published National Transportation Communications for ITS Protocol (NTCIP) 1211 v01, Object Definitions for Signal Control and Prioritization.

NEMA, AASHTO, and ITE have been jointly developing the National Transportation Communications for ITS Protocol since 1996. NTCIP is a family of communication protocols for traffic management devices.

NTCIP 1211 v01 is a device data dictionary standard that:

o defines data management information in terms of objects (data elements, data frames, and messages) related to traffic Signal Control and Prioritization (SCP) in NTCIP systems;

o covers the management of multiple requests for priority, or preferential treatment, among different vehicles or classes of vehicles (such as transit, emergency service, commercial fleet vehicles, etc.); and

o enables special coordination operations both within a traffic signal controller (primarily), and with adjacent intersections.

NTCIP 1211 v01 does not cover the process of generating priority requests, which is defined in other standards.

SCP management information includes individual parameters that represent the configuration, status, and control information for traffic devices. SCP management information also includes data frames and message sets for these parameters, and others, to address the operational information exchanges between the devices in a baseline system configuration.

The contents and scope of NTCIP 1211 v01 may be viewed, and a hard copy or electronic copy purchased for $115, by visiting NEMA's Web site at www.nema.org/stds/ntcip1211-v01.cfm, or by contacting IHS at 800-854-7179 (within the U.S.), 303-397-7956 (international), 303-397-2740 (fax), or on the Web at global.ihs.com.

NTCIP 1211 v01 will be available from the NTCIP website, www.ntcip.org, as a no-cost Adobe PDF download. This special offer is made possible by funding from the U.S. Department of Transportation's ITS Joint Program Office.

NEMA is the trade association of choice for the electrical manufacturing industry. Founded in 1926 and headquartered near Washington, D.C., its approximately 450 member companies manufacture products used in the generation, transmission and distribution, control, and end-use of electricity. These products are used in utility, medical imaging, industrial, commercial, institutional, and residential applications. Domestic production of electrical products sold worldwide exceeds $120 billion. In addition to its headquarters in Rosslyn, Virginia, NEMA also has offices in Beijing, Sao Paulo, and Mexico City.

AASHTO, founded in 1914, serves its member departments, the U.S. Department of Transportation, and Congress by providing leadership, technical services, information, and advice as well as by contributing to national policy on transportation issues. AASHTO is headquartered in Washington, D.C.

ITE is an international individual member educational and scientific association, and is one of the largest and fastest-growing multimodal professional transportation organizations in the world. Founded in 1930, the Institute is headquartered in Washington, D.C.
