ABSTRACT:
The present invention discloses a system capable of outputting a warning broadcast after picking up warning signals from a non-human-attended transmitter installed in a dangerous area, when an automobile runs such a dangerous area. Conventionally there are only warning signs installed on roads. If a driver enters into a dangerous area for the first time, or at night, the driver can often fail to properly cope with the suddenly appearing danger. The present invention gives a solution to such a problem in such a manner that a non-human-attended transmitter is installed in each of dangerous areas in order to emit relevant warning signals based on the particular feature of the danger lying ahead on the road (such as sharp curve of the road, steep slope of the road and the like), and that each automobile is provided with a receiver for picking up the warning signals emitted by the transmitter in order to output a warning broadcast by drawing the broadcasting data from a data memory of the receiver based on the received warning signals. Thus a driver is warned of the danger lying ahead in the form of a broadcast, so that the driver should be able to be ready for the imminent danger lying ahead.
