This document describes a proposed toll plaza system that uses RFID to automatically charge vehicles tolls based on their category. The system uses an 8051 microcontroller, RFID tags and readers, and other components like LCD screens and DC motors. Vehicles are assigned unique RFID tags tied to their category. When vehicles pass through the toll plaza, their tags are scanned and the appropriate amount is automatically charged to the associated account. The system aims to reduce congestion at toll plazas by providing a contactless payment option compared to traditional cash-based tolling.

3. INTRODUCTION
 Millions of driver pass
through toll booth
paying toll tax.
 Manual process is too
much time
consuming, so we go
electronic toll plaza.
 One such way of
automation is using
RFID.

5. DESIGN OF BASIC TOLL PLAZA
The design of toll plaza consists of
following components:
 MAX 232
 RS 232
 8051 Micro Controller
 Liquid Crystal Display(LCD)
 Crystal Oscillator
 DC Motor
 RFID

7. 8051 MICRO CONTROLLER
• Harvard Memory
Architecture – It has 16
bit Address bus (each of
RAM and ROM) and 8 bit
Data Bus.
• 8051 can execute 1 million
one-cycle instructions per
second with a clock
frequency of 12MHz.
• This microcontroller is also
called as “System on a chip”
because it has all the
features on a single chip.

8. The main features of 8051
microcontroller are
 RAM – 128 Bytes (Data
memory)
 ROM – 4Kbytes (ROM signify
the on – chip program space)
 Serial Port – Using UART
makes it simpler to interface
for serial communication.
 Two 16 bit Timer/ Counter
 Input/output Pins – 4 Ports of
8 bits each on a single chip.
 6 Interrupt Sources
 8 – bit ALU (Arithmetic Logic
Unit)

Display) screen is an
electronic display module
and find a wide range of
applications.

11. RFID
Radio Frequency Identification
and Detection
• RFID is a technology to identify and authenticate tags that
are us attached on vehicle(products)
• Each user holds a unique id for his vehicle, when user scans
his ID ,some amount is charged from his account depending
upon his vehicle category.
• This system depends on three devices
 Tag: Transponder
 RF Reader: Antenna
 Traffic Controller System
RFID Tag

12. WORKING OF RFID
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's
Types of RFID:
ACTIVE RFID
PASSIVE RFID

13. COMPARISOIN of RFID WITH OTHER
TECHNIQUES

14. ADVANTAGES & DISADVANTAGES
 ROAD USERS
 Increases user convenience from payment without
stops.
 Less Traffic Congestion.
 TOLL OPERATORS
 Less operating cost.
 Better audit control.
 GOVERNMENT/SOCIETY
• Transparency of Toll Transactions.
• Reduces Revenue Leakages.
RFID tags are inexpensive technology, and can
minimize cost to customer.

15. CONCLUSION
 RFID Technology is the best technology among all
automated technology
 Implementation of this technology will dramatically
decrease the traffic at Toll juncture.
 RFID has low cost, and high durability makes it suitable in
