USDOT is pleased to provide the ITS Standards deployment community with a new tool. The Center to Center (C2C) Reference Implementation (RI) Tool supports efficient deployment of systems using C2C communications by providing a means to verify conformance to C2C standards. Using the C2C RI tool will reduce developmental risks, effort, and the cost and provide consistent interpretation of the implemented standard, which in turn will encourage the deployment of interoperable NTCIP C2C systems. Learn more and download the C2C RI Tool.

Standards Announcements
- USDOT is pleased to announce IEEE’s publication of IEEE 1609.3-2016 Standard for Wireless Access in Vehicular Environments - Networking Services . IEEE 1609.3 defines network and transport layer services, including addressing and routing, in support of secure WAVE data exchange. It also defines Wave Short Messages, providing an efficient WAVE-specific alternative to IPv6 (Internet Protocol version 6) that can be directly supported by applications. Further, this standard defines the Management Information Base (MIB) for the WAVE protocol stack. The standards can be purchased from IEEE at http://www.techstreet.com/ieee.

Standards Announcements
- USDOT is pleased to announce SAE International's publication of J2735, Dedicated Short Range Communications (DSRC) Message Set Dictionary, for applications utilizing the 5.9 GHz DSRC for Wireless Access in Vehicular Environments (DSRC/WAVE) communications systems. This document defines the messages, data frames and data elements that make up the messages and is facilitated through tables in this document. Additionally, SAE published the J2945/1 On-Board System Requirements for V2V Safety Communications standard. This standard focuses on vehicle-to-vehicle (V2V) safety communications systems' requirements to support a set of six V2V Safety applications. The standards can be purchased from the SAE site at http://store.sae.org.
- USDOT is pleased to announce IEEE's publication of IEEE 1609.2-2016 Standard for Wireless Access in Vehicular Environments - Security Services for Applications and Management Messages and IEEE 1609.12-2016 Standard for Wireless Access in Vehicular Environments (WAVE) - Identifier Allocations. IEEE 1609.2 defines secure message formats, and the processing of those secure messages, within the DSRC/WAVE system. IEEE 1609.12 specifies allocations of WAVE identifiers defined in the IEEE 1609™ series of standards. The IEEE 1609.4 WAVE – Multi-Channel Operations standard is also published; this standard describes various standard message formats for DSRC applications at 5.9 GHz. The standards can be purchased from IEEE at http://www.techstreet.com/ieee.
