An RFID electronic tag based automatic vehicle identification system for traffic iot applications

This paper introduces the design and implementation of an active RFID tag based system for automatically identifying running vehicles on roads and collecting their data. The design principles and the architecture of the system are presented, including active electronic tags and reading equipments (readers and antennas), the monitoring base station deployment, the two-layered network construction, and the monitoring software. To solve identification uncertainty problems, the two key techniques are: anti- interference protocol and data clearing algorithm are proposed. Finally, the effectiveness and efficiency of the system is analyzed. The system will have wide applications in traffic IOT (Internet of Things) to support traffic monitoring, traffic flow statistics, traffic scheduling, and special vehicle tracking.
