Abstract: A method for managing an automatic parking lot involves determining a target space depending on an expected departure date of the vehicle, using a computation including allocating, to a new vehicle entering the lot, a target storage space according to the following rule: selection of spaces corresponding to one of the following criteria: o in the case where a row comprises at least one available proximal space, in front of a vehicle associated with a departure date after the departure date of the entering vehicle, o in the case where a row comprises at least one distal proximal space, positioning in a row the last vehicle of which is associated with a departure date before the departure date of the entering vehicle, allocating the target space to one of the selected spaces—otherwise allocating a space in a temporary storage zone including lanes of consecutive spaces.
