The invention concerns a signalling device (113-120, 149-156) equipping each spot (105-112, 141-18) of a parking lot capable of detecting (131) the presence of a vehicle on a parking spot in order to facilitate movements in the parking lot (101). The signalling device also comprises light-emitting elements (132) controlled by the detector indicating the status of the spot whether it is vacant or occupied. The signalling device further comprises a loudspeaker (133) for broadcasting information. The signalling device activates the loudspeaker depending on the status of the spot. The signalling device further comprises an interface (137) to be connected to a network for transmitting to one or more centralizing units the status of the monitored spot. |
