However, the traffic broadcast channel in the prior art can only provide the traffic conditions of roads in the whole driving area in a general way. The driver of the vehicle is concerned only about the road traffic situation in front of which the route is to be passed, and not about the road traffic situation in which the vehicle does not travel through the route or the area. The vehicle driver needs to screen the road traffic condition which is useful for the driver to reach the destination from the listened traffic broadcast channel in the driving process, the attention of the driver is dispersed, and the driving safety is affected. Since there is more useless information than useful information to listen to, some vehicle drivers give up listening to traffic broadcast channels and select a route empirically for their attentive driving. Thus, the prior art traffic broadcast channels do not provide targeted road traffic conditions.
In the prior art, subcarrier emergency traffic broadcasting modulates a digital signal on a frequency modulation subcarrier signal by a receiving frequency instruction signal, extracts the receiving frequency instruction by a special radio with the capability of receiving subcarrier signals, switches a receiving channel of the radio to a specified channel, and provides road traffic conditions by the specified channel. The scheme can solve the problem of providing road traffic conditions for vehicle drivers at proper time, but still cannot screen the listening information, and still has the problem of useless information spreading.
