Electronic Toll Collection System Using Radio Frequency Technology

This paper focuses on an electronic toll collection(ETC) system using radio frequency (RF) technology. Researchon ETC has been around since 1992, during which RFID tagsbegan to be widely used in vehicles to automate toll processes [1].Next method proposes a very simple method for enhancing theperformance of infrared electronic-toll-collection systems,resulting in longer communication time interval for the datatransmission between the on board unit (OBU) and the road sideunit (RSU). The proposed RF system uses antenna that aremounted on the windshields of vehicles, through whichinformation embedded on the tags are read by RF readers, the tolldebit will be taken from the owner’s bank account. The proposedsystem eliminates the need for motorists and toll authorities tomanually perform ticket payments and toll fee collections,respectively. Data information are also easily exchanged betweenthe motorists and toll authorities, thereby enabling a moreefficient toll collection by reducing traffic and eliminatingpossible human errors.
