Abstract: Identification and positioning arc key technologies for vehicular Ad hoc nctwork(VANEI})，also a hot research topic in recent years. A vehicle identifiable information identification method based on radio frequency identification (RFID) was proposed, and a coding structure using EPG64 type班for vehicle identity information was put forward. I}he global positioning system (GPS) positioning method, the dead reckoning (DR) positioning method and the base station wireless positioning method algorithm and precision analysis were introduced. On this basis, the application priority of GPS positioning method for VANET was confirmed. Finally,a identification and positioning method combining RFID and GPS for VANEI} was proposed. I}he experiment shows that the method preliminary reaches the application rectuirements for VANE?.
