Appendix D—Current ITS Standards

Appendix D lists all of the ITS standards that have been published or are in development as of November 2010. The standards are grouped by subsystems of the National ITS Architecture. The relationship between the ITS standards and the National ITS Architecture is also illustrated in Figure 4 which categorizes the standards using color to denote their NTCIP level.

Within the Architecture, an ITS standard serves one of three roles: information exchange, message definition, and device management (see the introduction for full descriptions). Each standard’s role is indicated in the fourth column in the table. Some additional standards listed in the table provide supporting information to standards and system developers rather than serving one of these three roles.

The table also indicates whether each standard has completed the SEP, is in the process of being revised using the SEP, is being considered for future SEP work, or is not applicable to the SEP.

Entries in italics in gray text are standards that are no longer in use. Standards that are no longer in use also show “Not in Use” in the SEP column.
