Rai Isoradio

Rai Isoradio is an Italian highway advisory radio service devoted to delivering updated traffic reports (known as "Onda Verde") and weather reports provided by Aeronautica Militare, public service announcements by various governmental and public organisations, railways information from Ferrovie dello Stato, news bulletins from GR1, TG1 and TG3, and music.
In collaboration with "Autostrade per l'Italia" and Autostrada dei Fiori, "Rai Isoradio" covers all Italian highways (mostly on 103.3 MHz). During nighttime hours (0:30-5:30, known as "Isonotte"), the network also carries non stop independent Italian music (interrupted by traffic information every 30 minutes).
