The signaling system (1) uses sensors for exterior parameters and signal communication device, containing control data function of exterior parameters. Processor is designed to operate warning signal transmitter as function of control signal and transmission signal data received by device, and/or to establish communication signals designed to be transmitted by device. Independent claims are also included for the group of signaling systems interacting together and driveway with a group of signaling systems fitted. |
