Abstract: Methods, apparatuses and systems for identifying overstay of a vehicle (624, 644) in a parking space (610, 620, 630, 640, 650, 660) are disclosed herein. The method comprises the steps of detecting presence of a vehicle in a parking space using a detection apparatus (612, 622, 632, 642, 652, 662), processing and storing data relating to presence of the vehicle in the detection apparatus, wirelessly (672, 674) waking-up the detection apparatus, wirelessly retrieving at least a portion of the data from the detection apparatus, and identifying overstay of the vehicle in the parking space based on the retrieved data. Wireless wake-up of a detection apparatus may be irregularly performed by an occasionally present data collection apparatus (680). Apparatuses and systems are disclosed for performing the foregoing method.
