NEMA, AASHTO, and ITE Release NTCIP 1209 v02 on Transportation Sensor Systems

06/9/2014 1:00PMSign-up to receive press releases.

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) 1209 v02, Object Definitions for Transportation Sensor Systems (TSS).

NTCIP 1209 v02 includes requirements for communicating between TSS field devices and the host or central systems (including a traffic management center) that control and monitor a TSS. TSS data describes certain traffic parameters including accurate, near real-time information on traffic flow. Traffic flow is characterized by data that describe the number of vehicles in various portions (sometimes lanes) within a TSS zone. TSS data may be acquired using field devices that rely on a number of different technologies to detect vehicles.

A hard copy of NTCIP 1209 v02 may be purchased for $161 and an electronic copy may be purchased for $80 by visiting the NEMA website.

Since 1996, NEMA, AASHTO, and ITE have been jointly developing NTCIP, a family of communication protocols for traffic management devices.

NTCIP 1209 v02 is also available from the NTCIP website, www.ntcip.org, as a no-cost Adobe PDF download. This special offer is made possible through support from the U.S. Department of Transportation Joint Program Office, whose assistance is gratefully acknowledged.

AASHTO, founded in 1914, is a nonprofit, nonpartisan association representing highway and transportation departments in the 50 states, the District of Columbia, and Puerto Rico. It represents all five transportation modes: air, highways, public transportation, rail, and water. Its primary goal is to foster the development, operation, and maintenance of an integrated national transportation system.

ITE, founded in 1930, is an international educational and scientific association of transportation professionals who are responsible for meeting mobility and safety needs. ITE facilitates the application of technology and scientific principles to research, planning, functional design, implementation, operation, policy development and management for any mode of ground transportation. Founded in 1930, the Institute is headquartered in Washington, D.C.


The National Electrical Manufacturers Association (NEMA) represents nearly 350 electrical equipment and medical imaging manufacturers that make safe, reliable, and efficient products and systems. Our combined industries account for 360,000 American jobs in more than 7,000 facilities covering every state. Our industry produces $106 billion shipments of electrical equipment and medical imaging technologies per year with $36 billion exports.
