A prefabricated continuous multilayer road-marking tape is described, which includes retroreflecting optical components, light emitting diodes (LEDs), solar cells, storage batteries, and reflectors and transmitters of electromagnetic waves. There are given examples of the use of the reflectors in order to control the speed of a vehicle which travels far from the tape, and examples of the use of EPROMs (erasable programmable read only memory) where messages are recorded, with the purpose of giving information about the conditions of the road, the presence of ice or of traffic jams, and so on, said messages being transmitted by a radio transmitter.
