The document describes an electronic toll collection system using RFID tags and a microcontroller. Vehicles are provided with RF transmitters that broadcast identification information as they pass toll plazas. RF receivers at the plaza receive the signals and deduct tolls from prepaid accounts in a central database. This automates the toll collection process, reducing traffic and operating costs while increasing convenience by eliminating stops. The system aims to reduce money loss and processing time at toll plazas through effective automation.

Objective:
•The objective of this is to automate the toll collection system using RFID tags and Microcontroller.
At every toll collection center, RF receiver will be interfaced with PC.
•Each vehicle will be provided RF Tx that will transmit its identity whenever it will pass through this
toll collection centre.
•In data base of the PC, information of the vehicle will be stored. (Vehicle no. account status, etc.).
The RF Rx at toll collection centre will receive the data from vehicle & deduct the amount of toll as
per the tariff. MC will be used with RF Rx.
•Camera will be installed at toll collection center which will take the image of the vehicle (vehicle
no. or photo of the driver) for security purpose.

Introduction:
•In 1959, William Vickrey was the first to propose a system of electronic tolling for the Washington
Metropolitan Area.
•With the increase in the number of vehicles on road ,the task of traffic management becomes more
complex. It is complex to maintain the details of each vehicles.
•Electronic toll collection (ETC) aims to eliminate the delay on toll roads by
collecting tolls electronically. ETC determines whether the cars passing are enrolled in the program,
alerts enforcers for those that are not, and electronically debits the accounts of registered car owners
without requiring them to stop.

Working:
•As a vehicle approaches a toll plaza,the radio frequency field emitted from the antenna activates
the transponder.
•The transponder broadcasts a signal back to the lane antenna with some basic information.That
information is transferred from the lane antenna to the central database.
•If the account is in good standing,a toll is deducted from the driver’s prepaid account.
•If the toll lane has a gate, the gate opens.
•A green light indicates that the driver can proceed.

RFID tags:
•RFID system uses various frequencies but most common
and popularly used frequency is low,high and
ultra high frequency.
•Low frequency is around 125 KHZ.
•High is around 13.56 MHZ and ultra high varies
between 860-960 MHZ.
•An RFID tag or transponder consists of a chip and an antenna.
•The microchip contains memory and logic circuits to receive and send data back to receive and send
data back to reader.
•The RFID tag is mounted on windshield of vehicle.

Reader:
•A reader contains an antenna to transmit and
Receive data from the tag.
•The reader also contains a decoder and an RF
module.It could be mounted or built as
a portable handheld device.

In lane computers:
•The in lane computer checks the data against a database of valid tags and active
accounts,deducts the appropriate toll from the customer’s account .
•Approves passage or raises a tollgate to allow the vehicle to pass through the toll plaza.

Advantages and disadvantages:
Road users
•Increases user convenience from payment without stops.
•Less traffic congestion.
Toll operators
•Less operating cost.
•Better audit control.
Government
•Transparency of toll transactions.
•Reduce revenue leakages.

CONCLUSION:
•By doing automation of toll plaza we can have the best solution over money loss at toll
plaza by reducing the man power required for collection of money and also can reduce the
traffic indirectly resulting in reduction of time at toll plaza.
•Effectively utilizing this technique at different stages of our project we are able to represent
the automation in toll plaza which will reduce the complete processing time by few seconds
which is very important as well as helps to reduce money leakage in cost effective manner.
