The system is extremely compact and doesn’t need any expensive additional infrastructures. It can be mounted in fixed positions (highways, road tunnels...) or on mobile posts (to alert people about temporary roadworks, accidents, traffic jams...).
It can transmit an audio message, a voice alert or other messages. Thanks to embedded RDS encoder, it uses the “Emergency Alert” function to make the radio switch automatically to the FM tuner, transmitting the alert signal both as an audio message and as an RDS text.
Even if the driver is listening to a CD or an MP3, the receiver with an active RDS Traffic Alert warning will automatically switch to the FM tuner in order for
the alert to be heard.
