A non-transitory computer-readable medium of a reservation controller contains instructions executable by a processor. The instructions include receiving a user request for a requested space, where the user request includes a time slot for a use of the requested space. The instructions include identifying unoccupied spaces based on current status information from multiple occupancy sensors in response to determining that the time slot is within a threshold period of time from a current time. The unoccupied spaces are one or more of multiple spaces that are currently unoccupied. The instructions also include identifying available spaces from among the unoccupied spaces and reserving a matching space from among the available spaces.
