Abstract

To reduce the traffic jam at toll plazas and to save time, & also to decrease the wastage of money of almost 300 crores per annum, this paper is designed for the “toll tax payment automation using Radio Frequency Identification (RFID)”. Automation of toll plaza is made using combination of microcontroller and RFID technology. Using RFID technology, priority of the vehicle (ambulance or fire brigade) can also be calculated to give free and easy access through toll plazas. This paper aims to design a system, in which vehicles reaching the toll booth and vehicle number and it’s time are automatically identified. The electromagnetic signal received from a reader is worked upon by the passive tag on the vehicle. An internal capacitor on the tags is charged by the electromagnetic signals that are received, that seems like a source of power and supplies it to the chip. The RF signal from the tag is then amplified and is forwarded to microcontroller through the reader. ID is displayed on the LCD using microcontroller and based on the balance, decisions are made.
