<p>There is described a composite system for providing informations to motorists along a road. The system is characterized by the cooperative combination of transmitting and receiving active electronic components, typically "secondary radar" arranged aboard a vehicle and designed for emitting energy in the direction of travel along the road, of passive components which are selectively located beneath a prefabricated tape-like layer and designed for returning said energy to the receiving components on board of the vehicle, and of horizontal signalling components, designed for positively providing optical informations to a motorist. The invention is concerned also with the method for the system.</p> |
