Published Standards

NTCIP 1218 v01, Object Definitions for Roadside Units (RSUs)

NTCIP 1218 v01 provides definitions of data elements for use with Roadside Units (RSUs). NTCIP 1218 v01 specifies the logical interface between an RSU and the controlling management stations. NTCIP 1218 v01 defines information that may be exchanged across this interface. NTCIP 1218 v01 first identifies the relevant RSU users and their needs, defines requirements that enable information exchanges that supports those needs, and finally defines the data objects and meta-data, including the relative structure of that data, necessary to meet these requirements. NTCIP 1218 objects use Simple Network Management Protocol (SNMP) object-type format as defined in RFC 1212, specifically, the objects use SNMPv3 format.  Published September 2020.

NTCIP 1218 v01A-SE01 TPG is the TPG-enabled version of NTCIP 1218 v01. It is designed for TPG (Test Procedure Generator) software users. Published September 2020.
