As a most simple example meaning the following: Consider a Road Operator, with a big CCTV traffic flow video wall, suddenly spotting a wrong-way-driver on a motorway The operating person in charge should NOW have a Red Button to point the map at the wrong-way-driver spot and instantly, without any further action, cry out a wrong-way-driver-warning-message over ALL kinds of communication channels, with ALL communication-channel operators that offer coverage in the effected geographic area over ALL kinds of communication technologies C-ITS and Hybrid Communication Commercial in confidence 2015-03-26 Page 16
Communication technologies in question are Cellular 3GPP communication (e.g. HSPA, LTE, LTE-A, ) ETSI ITS G5 (802.11p) communication, via so called RSUs (road-site-stations networks) Via the road-operators own VMS (Variable Message Sign) systems Via public broadcast channel providers (FM radio, RDS-TMC, DAB+ TPEG, etc) Communication channel operators are all MNOs that provide cellular coverage in that effected area the one (or maybe two) operators of an ETSI ITS G5 RSU-network along the effected roads the road-operator s own VMS operation system (might be run by an outsourced partner) the different broadcasters, serving that area C-ITS and Hybrid Communication Commercial in confidence 2015-03-26 Page 17
