NTCIP 1202 v04 Actuated Signal Control (ASC)

The United States Department of Transportation (USDOT) and the Institute of Transportation Engineers (ITE) and their standards development partners, AASHTO and NEMA have worked on ITS Standards since the inception of the ITS Standards Program in 1996, almost 3 decades ago. This project includes the steps necessary to publish a “The National Transportation Communications for ITS Protocol (NTCIP) 1202 version 4”, hereinafter referred to as NTCIP 1202 v04, under the purview of ITE. The current version of NTCIP 1202 is version 3A (NTCIP 1202 v03A), which incorporated new user needs, requirements, and design elements to better enable ASC to Roadside Unit (RSU) communications. Subsequently the Connected Intersections standardization project developed detailed guidance for interoperable deployments of connected intersections which include an ASC and RSU. Part of that effort identified new signal, phase, and timing (SPaT) concepts, such as the Assured Green Period (AGP), which need to be formally added to NTCIP 1202.

NTCIP 1202 v04 incorporates new updated user needs, requirements, and design elements resulting from the Connected Intersections standardization effort, results from the City of Anaheim NTCIP 1202 testing project, recommended changes from NTCIP 9014 Infrastructure Standards Security Assessment (ISSA), and other infrastructure owner operator (IOO); vendor comments and suggestions. NTCIP 1202 version 4 will provide the ITS Community with a complete and correct standard that has been through a systems engineering process and supports full nationwide interoperability for Acuated Signal Controllers (ASC).

Objective

The primary objective of this project is to publish a non-proprietary, industry-based consensus standard for object definitions in ASCs. The final output will be a published standard that supports center-to-field communications to support connected vehicle technology, updated, secure communication protocols such as SNMPv3, and to include resources for testing ASCs and their compliance with the standard.

NTCIP 1202 v04, an NTCIP standards publication, identifies and defines how a management station may wish to interface with a field device to control and monitor traffic signal controllers and associated detectors in an NTCIP-conformant fashion. NTCIP 1202 v04 may also identify and define how a traffic signal controller might communicate signal timing information with an external device, such as a roadside unit..

NTCIP 1202 v04 defines data elements for use with Actuated Signal Controller Units. Previous versions of NTCIP 1202 used SNMPv1. NTCIP 1202 v04 uses SNMPv3 and does not support SNMPv1.

Notice of Intent (NOI) to Adopt the NTCIP 1202 V04 Actuated Signal Controllers proposed Recommended Standard (pRS)- BALLOTING IN PROGRESS

The Institute of Transportation Engineers (ITE) intends to adopt the following National Transportation Communications for ITS Protocol (NTCIP) 1202 V04 Actuated Signal Controllers (ASC) as a Recommended Standard (RS) assuming no final comments or appeals are received. The final draft versions of this NTCIP Standard's proposed Recommended Standards (pRS) are in balloting. Please check below for the final draft versions Standard, the Standards Development Reports, and a notice as to whether these versions have been adopted by ITE.  When adopted, these standards will be jointly published by ITE, NEMA and AASHTO.
