The goal of any radio station is to promote and increase the quality of the audience, where the tools to achieve them are the contents of the programmes and the optimization of the schedule. Mobile users, especially car commuters, are of great interest.

They can guarantee a continuous listening during the usual House-Office itinerary, sometimes of considerable duration, and select the stations according to their specific sensitivity to the various proposed contents.

The disadvantage of “generalists” traffic news reports

For the broadcast characteristic of the radio signal, the information is generalist: news is broadcast with the most important events in the radio audience Basin. The news is necessarily short-lived and at short intervals, so as not to annoy the listener with traffic news which, in fact, will rarely be relevant to his itinerary.

Some statistics have shown how, in a catchment area as large as Italy, the probability that a newsletter of a dozen events transmitted with a frequency of 15 minutes can provide a useful information for the individual motorist is less than 1 in 10 million!

The advantage of a platform offering selected information for a specific geographical area

Traffic Over Voice is the Duel service platform for radio stations which, in addition to fulfilling a duty of information, also intend to make a real and effective contribution to their listeners. With TOV Duel, it proposes a new and more effective way of transmitting traffic information, which is immediately accessible and at marginal costs.

It is a service platform, accessible via network through subscription subscription, that produces traffic news in a natural language, selected by event gravity within a macroscopically defined territorial basin by the issuer with a simple graphical area on the map.

Ready and Timely: the Radio as a Navigator!

The news, processed from traffic HD Flow data from TomTom, is also accompanied by short forecasts (10 to 30 minutes) and updated with a frequency of 2 minutes.

The news, selected according to the catchment area and gravity, is transmitted at predefined intervals or times, or even with the intervention of the speaker during the radio program. Individual traffic events are monitored by the system during their evolution, proposed for the transmission and proposed only in the event of significant changes (great increase or reduction of the code) or when the event has ceased its effect.

The service is available in the USA, Germany, France, Holland, Belgium, Italy and continues to be extended progressively in the major western nations of the world.


Duel has developed a software module for the translation of events from DATEX II format to XML format to feed traffic broadcasting systems on FM radio (RDS-TMC) and digital (TPEG). The translation system analyzes the DAG that represents DATEX II events and through a set of rules inserted in an appropriate inferential engine generates one or more DATEX events to be published describing, as faithfully as possible, the original event.
