The Collaboration on ITS communication standards (CITS) serves as an
international platform for the coordination of globally acceptable, and
harmonized standards on Intelligent Transportation Systems (ITS) in order to
enable the rapid deployment of fully interoperable ITS communication-related
products and services.

In keeping with its mandate, in March 2019 CITS agreed to establish an online
database for ITS Communication Standards. To furnish this database with key
inputs from participating SDOs, these entities were invited to review the
categorisation of their related-standards and to appoint an expert to maintain
the relevant communication standards in the online database.

Over the course of two years, the database has been significantly updated with
inputs received through liaison statements as well as those presented during
the six monthly CITS meetings.

The current version of the online database is already accessible here
It includes standards from 3GPP, ETSI, IEEE, IETF, ISO, ITU, SAE, TTC, and W3C.
In order to keep this database as up to date as possible, CITS would like to
encourage you to participate regularly in the CITS e-meetings and provide any
relevant inputs either via presentations to the meeting or through formal
channels including liaison statements. We are also attaching the current list
of contact points from various organizations. Please provide any update as
needed to both the online database and the list of contact points in your
organization (attachment below).

The CITS Secretariat ( remains at your disposal for any
additional queries.

We look forward to continuing our collaboration with your organization.
