Due to recent technology advancements, RFID readers have been proposed for several vehicular applications ranging from safe navigation to intelligent transport. However, one obstacle to deployment is the unpredictable read performance. An RFID reader occasionally fails to read an RFID tag even in static circumstances, mostly due to collisions. In a mobile vehicular environment, latency becomes the key performance factor because of the high speed of vehicles. This is particularly true when the RFID reader is on the moving vehicle. In this paper, the authors investigate RFID read latency and thus effectiveness of on-vehicles reader installations for a wide range of speeds. First, they experimentally study the impact of reader and tag relative positions on read errors and read rates. Then they conduct road experiments at varying speeds. The results reveal the critical factors that influence on-vehicle RFID read performance, and give them guidance to identify and pursue directions for improvement. The paper is organized as follows. In Section 2, the authors discuss new vehicular applications enabled by the proposed RFID system. Section 3 reviews the RFID system from the performance viewpoint. Section 4 introduces and examines the RFID system used in the experiments and its factors affecting RFID read performance. In Section 5 laboratory experiments are conducted to develop an effective strategy for RFID installations on the vehicle and on the road. RFID read performance is estimated in a testbed in Section 6. Finally, Section 7 concludes the paper.
