Abstract (en)
The invention relates to a system for the transmission and reception of information to motorists between a plurality of transmitter stations and a plurality of receiver stations installed on motor vehicles and a plurality of sensor devices disposed along the road network for detecting information on ambient and climatic road conditions; each transmitter station comprises: a sensor circuit module, a processor circuit module for managing and processing all the information which it receives and for generating coded output signals, a communication circuit module for bidirectional management of coded signals coming from the processor circuit module and from a control unit and a further plurality of transmitter stations installed along the road network, a transmitter circuit module, and a supply circuit module; each said plurality of receiver stations comprises: a radio frequency circuit module, a logic circuit module for recognising codes and decoding received input information from the said circuit module, a silencing circuit module, an audio circuit module such as to activate sound circuit means and a signalling circuit module. <IMAGE>
