  • Said processing means 5 are further capable, if necessary, of operating said warning signal means 3 as a function of the data recorded by said detection means 2 of the device.
  • said signaling device will then only serve as a relay for transmitting communication signals which are not intended for its own use. but intended for an external target.
  • the device according to the invention further comprises, for example, means 10 for storing at least one identification code of said device.
  • said processing means are able, on the one hand, to carry out a comparison of said identification code or codes with one or more identification codes 11 contained in the received communication signals, so as to check whether they must take into account or ignore the control information contained in said signals, and / or on the other hand, to be included in the transmitted communication signals, alongside said control information contained in said signals, the identification code or codes 11 of said device.
  • said processing means may also be provided capable, if necessary, of modifying said group identifiers 11 and / or said individual identifiers 12, in particular in the event of the issuance of a said signal communication by the signaling device concerned.
  • Said communication signal 6 thus consists of a frame containing at least, for example, said control information or items 7, the group identifier (s) 12 and / or the individual identifier (s) 13.
  • said detection means 2 are capable of detecting, in particular, in a given area, the presence of objects, of fog and / or the day / night alternation.
  • ultrasonic sensors 14 They are made up for this, for example, of ultrasonic sensors 14, hygrometric sensors 15 and / or brightness sensors 16. They are located, in particular, on one and / or the other of the faces of the head 9 of said stud.
  • Said means 3 for transmitting warning signals may possibly deliver visual indications, adapted to the nature of said external parameters. They are therefore made up, for example, of light-emitting diodes 17, of different colors. Said diodes are located, in particular, on the lateral faces of the head 9 of said pad 1.
  • the device according to the invention may, in addition, include autonomous means 18 for supplying energy.
  • They will consist, for example, of means for transforming solar energy, in particular photoelectric cells 19, of a battery and / or of means for regulating the electric energy supplied by said battery and / or said means of transformation. of solar energy.
  • energy is supplied by said means for transforming solar energy which, at the same time, recharges the battery. At night, it is the latter that supplies electrical energy.
  • Said means 4 for exchanging communication signals consist, for example, of transmission / reception means, in particular with frequency modulation.
  • Said processing means 5 comprise, for example, a microprocessor.
  • the invention also relates to a set of devices in which said communication signals 6 are sent and / or received by said devices, which thus constitute an autonomous closed network.
  • Each said signaling device analyzes the external parameters in a given zone 22, thanks to its detection means 2, said signaling devices being spaced apart so as to minimize the overlap between the action zones of each of them and the power of the transmission means 3 adapted to the dimensions of said zones.
  • said devices are optionally distributed by group a, b, c, d, each device of the same group being provided with the same said group identifier.
  • said devices are oriented with respect to each other in a given direction and direction 20, 21, the devices of the same group having an individual identifier increasing or decreasing from one device to another, according to said direction. given.
  • the latter corresponds, for example, to the direction of traffic and the signaling devices communicate with each other in the opposite direction to said given direction.
  • the invention also relates to a roadway 23 provided with a said set of signaling devices. Said pads 1 are placed therein at a given interval. They are located one behind the other in the direction followed by said road, in particular at the level of its center line.

  • Said studs 1 can be spaced apart from 10 to 25 meters and divided into groups of about 500 meters, to warn drivers of a danger early enough.
  • the plots located in two successive groups will preferably not have the same group identifiers.
  • the studs located at the same level on each of the roadways will also have different group identifiers. This will avoid reporting on one roadway, a danger existing only on the other.
  • a pad 1 detecting a danger at a given location will only transmit information to the pads located upstream. from this place, the concept of upstream and downstream being defined by the direction of progression of automobiles.
  • the studs 1 can communicate the information both upstream and downstream and be provided with means 3 for issuing warnings oriented in both directions.
