Cooperative ITS

CEN/TC 278/WG 16

Cooperative ITS (C-ITS) has the potential to further increase the benefits of ITS services and applications. C-ITS is a subset of the overall ITS that communicates and shares information between ITS Stations* to give advice or take actions  with the objective of improving safety, sustainability, efficiency and comfort beyond the scope of stand-alone ITS.

(* ITS Station defined in ETSI EN 302 665 and ISO 21217)

ITS-S reference architecture (ISO 21217:2014)


A series of webinars on C-ITS standardization will be held during 2020. You may register for attending a webinar by sending an email, providing your name, your affiliation, country of residence, and the date of the respective webinar. Upon registration, you will receive an email with the login information.

The first webinar took place on on 21 April 2020.
