The invention relates to a vehicle access management system, in particular to a radio frequency identification (RFID) technology-based vehicle access management system for managing the access of a vehicle, which comprises a computer (1) and a road-gate device (2), wherein the gate device (2) comprises a road-gate controller (3) and a road gate (4). The system also comprises an RFID reader (5) and an RFID electronic label (6) which is arranged on the vehicle, wherein the computer (1) is connected with the RFID reader (5), and the RFID (5) is also connected with the road-gate controller (3). The RFID technology-based vehicle access management system has the advantages that: (1) the identification speed is fast, the accuracy is high, the passing efficiency of the vehicle is high, the releasing speed is fast, the crowding of the vehicle at the gate can be avoided, the safety is good, the labor cost can be reduced, and the automatic management of the passing of the vehicles can be realized; (2) the system is convenient to use; (3) the reliability and the stability are good, and the maintenance cost is low; and (4) the confidentiality is high, and the anti-counterfeit performance is good.
