My city has recently introduced a new parking monitoring system which uses embedded, solar powered, sensors in each parking space along with a wifi mesh network to coordinate timed parking spaces (free and paid) and notify the authorities if users run over time.
It also is utilised in parking structures to show a simple visual indicator of whether a park is free or not via a system of red or green lights.
