The implementation of the RFID technology in traffic monitoring is important for the intelligent transportation system. However, one of the problems that face this technology is tag collisions which are due to simultaneous tag responses to the reader. This paper investigates the performance of two known anti-collisions protocols: the Basic Framed Slotted Aloha (BFSA) and the Dynamic Framed Slotted Aloha (DFSA). The study considers the case where an RFID reader is mounted over the middle of the road and covers two lanes of a typical highway. For such application, it was found that the DFSA method outperforms the BFSA method. In addition, the study compares the performance of three tag estimators associated with the DFSA: Vogt, Zhen and Schoute. It is observed that the Vogt method is the best if the number of tags is low, while the Schoute approach is superior for higher value. The study proposes a hybrid tag estimator that combines the strength of the Vogt and Schoute approaches.
