The ESF news on C-ITS edition 2014 will be published in January 2015.
This new edition will inform about messaging protocols and their usability over narrowband channels at 5,9 GHz. This edition is designed for decision makers in Europe (C-ITS Corridor and other deployment projects), in the USA (NHTSA deployment project), and in other regions (Australia and Asia). The standards development organisations ISO, ETSI, and IEEE are mainly affected with their standards on FNTP (ISO 29281-1), GeoNetworking (EN 302 636 series), and WSMP (IEEE 1609.3).
It is intended to publish a harmonised messaging protocol in 1609.3 version 3, and in ISO 16460. Major focus in IEEE is on the efficient broadcast mode for BSM dissemination to neighboring stations. Major focus in ISO is on the efficient unicast communications in short sessions initiated by the Service Advertisement service standardized in ISO 24102-5.
