Abstract:
1. A method for determining a state of occupancy of a plurality of scheduled areas by vehicles, comprising the steps of: associating with each of the plurality of scheduled areas to be monitored a transmitter which periodically transmits a signal of fixed power; receiving in a concentrator each signal emitted by each of the transmitters; examining each signal emitted by each of the transmitters and determining the occupied/vacant state of each of the plurality of scheduled areas to be monitored based upon monitoring a received signal intensity of each signal with a predetermined value, wherein the determining step includes defining the state of a first area as occupied when the intensity of the received signal of said first area is less than the predetermined value, and wherein the predetermined value varies with time; periodically transmitting a signal by the concentrator comprising information on an occupied/vacant state of each of the plurality of scheduled areas to an operating centre; and generating information indicative of the state of occupancy of each of the plurality of scheduled areas.
