ESTIMATING PARKING SPACE OCCUPANCY USING RADIO-FREQUENCY IDENTIFICATION

摘要

An example system configured to determine a status of a parking space includes an RFID reader, and at least one RFID tag positioned at the parking space. The RFID reader interrogates the RFID tag. The RFID reader determines that the parking space is unoccupied when the RFID reader receives a response from the RFID tag. The RFID reader determines that the parking space is occupied when the RFID reader fails to receive the response from the RFID tag.
