Norway - Emergency Broadcasting - History
18.08.2015
All relevant tunnels in Norway will have DAB-coverage before FM-shutdown, and all tunnels that require FM-coverage today, will then be equipped with DAB. Contrary to FM, where only a few channels have tunnel coverage, all channels on the outside of a tunnel will be available also on the inside.
In an emergency situation, the Road Authorities will be able to transmit messages on all DAB stations broadcast into the tunnel, from the outside of the tunnel or from the operations central. This will effectively mean a higher security for all travellers in road tunnels, as messages will reach all radio listeners - not only those listening to a specific channel. In Norway there are approximately 260 road tunnels with broadcasting integrated today. At FM shutoff all of these will have DAB and accordingly all new tunnels longer than 500 meters with annual traffic over 5000 vehicles.
