The present invention discloses a solution for improving shared space availability by dynamically responding user utilization behavior of shared space. In the system, automated sensors within a shared space can be used to detect when spaces are in use. Sensors such as motion detectors, infrared sensors, cameras, and the like can correlate space usage to a reservation system. When a space is reserved by a user, the system can verify space occupancy according to the reservation. If the space is unoccupied and the reservation time has not expired, the space can be automatically freed. If the excess time before reservation expiration is more than a threshold value (e.g., fifteen minutes) the system can penalize the user. Penalties can be applied for users that do not utilize reservations.
