Abstract: A method for determining the state of occupation of a plurality of scheduled areas by vehicles, comprising the steps of: associating with each area to be monitored a transmitter which periodically transmits a signal of fixed power; receiving in a concentrator the plurality of signals emitted by said plurality of transmitters; examining said plurality of signals and determining the occupied/vacant state of each area to be monitored; periodically transmitting a signal comprising information on the occupied/vacant state of each monitored area to an operating center; generating information indicative of the state of occupation of a plurality of areas.

Abstract: A system for managing geographically distributed resources, comprising a plurality of shoes associated with said resources; each pair of said plurality of shoes comprising an electronic circuit; said electronic circuit comprising a control circuit for said electronic circuit; a locator module which provides the geographical coordinates to said control circuit; a radio communication system; said control system providing a plurality of information items to said communication system; said communication system comprising a first receiver-transmitter for sending said plurality of information items to a local concentrator; said local concentrator comprising a second receiver-transmitter for sending said plurality of information items to an operations center; said first receiver-transmitter sending said plurality of information items to a local concentrator periodically; said control circuit comprising an input connected to at least one sensor; said operations center displaying the location of each of said resources
