ABSTRACT
Tollway applications constitute one of the earliest and most mature uses of RFID technology. The need for a large volume of reads and the relatively consistent positioning of the host vehicle make this process ideal for the use of RFID tags. At the current state of development, the use of RFID tags are estimated to provide a 250 to 300 percent increase in tollway throughput. This increase in performance is just one benet. Some tollway RFID reader systems can simultaneously monitor up to eight lanes. This level of automation not only increases throughput but also lowers operational costs by being able to reduce the workforce. Some tollway authorities pass on the savings to the patrons. The Harris County Texas Tollway administration, for example, offers a 25 percent reduction in toll costs for the use of their E-ZPass system. Lastly, the use of RFID tag systems on tollways also has environmental impact. A savings of 1.2 million gallons of fuel is estimated as a result of vehicles not having to wait in line to pay tolls.
