Research Report Automation of Toll gate and Vehicle Tracking
1. INTRODUCTION
With the increase in the number of vehicles on-road, the task of traffic
management becomes more complex. It is hard to keep & maintain the details of the
each vehicle, which is running on the road. Also in case of hit –and-run or carrying of
illegal goods over inter-state cross boarder or road-robbery cases, the police may
not trace the culprits very easily, as the vehicle details are not monitored
continuously.
Suppose The Cargo Company wants to send a message to its On-road
vehicle to stop delivering the goods to customer, policeman want to stop a vehicle
which is smuggling some illegal goods or city transports want to track each buses
details such as departure and arrival time on bus terminal, number of round trips it
has undergone in a single day. All this is possible by the use of automated toll gates.

This system is intended to help the RTO, Police Department, Public Transport
and Cargo Companies to track the vehicles. This system comprises of Toll Gate
office having a personal computer connected with the receiver and the software to
run the “Automation of Toll Gate” system. To implement this system, every vehicle
1
Research Report Automation of Toll gate and Vehicle Tracking
must be fitted with a remote transmitter, hidden behind the number plate of the
vehicle. The transmitter continuously sends the number of vehicle on which it is
mounted, in coded form. When a vehicle enters the zone of toll office, the sensors
fitted on either side of the road, sense and send the signal to the toll office control
unit. This micro controller based control unit activates the number plate sensor,
which in results receives the number of the entering vehicle [capturing the signal
sent by vehicle’s remote transmitter] and sends it to computer.
The computer scans its centralized database and displays the details of that
vehicle with the current time and date. The details can be: registration number and
model number with vehicle’s body color, owner’s name and address, date of
registration, current status-clear or in black listed etc. If the vehicle records show that
its current status is clear, then the gate will be opened automatically.
Otherwise, the gate will not open and the vehicle owner can be called for
further enquiry. This system can be used at the regional Transport Office to watch
the unregistered vehicles or trace the other state vehicles. The public transport s can
keep the details of each vehicle’s check-in and check-out times with number of round
trips it makes in a day. The police department can easily stop the wanted vehicle, by
posting the vehicle’s registration number on its data base. If the toll gate PC checks
its data base and finds the current status as ‘wanted’, it does not open the gate and
immediately alerts the concerned authority. This system is a step towards improving
the tracking and monitoring vehicles of traveling in predetermined routes. Here, a
computerized system automatically identifies an approaching vehicle and records the
vehicle number and time. If the vehicle belongs to the authorized person/group, it
automatically the toll gate and a predetermined amount is automatically deducted
from its account. There are many benefits of Toll Gate Automation. The average
service time with E-pass is 2 seconds compared to 30 seconds for manual collection.
This translates to reduced traffic congestion at toll plazas, lower fuel consumption,
less air pollution, and therefore less economic losses.

2. HISTORY
In 1959, Nobel Economics Prize winner William Vickrey was the first to propose a
system of electronic tolling for the Washington metropolitan area. He proposed that
each car would be equipped with a transponder. “The transponder’s personalized
signal would be picked up when the car passed through an intersection, and then
relayed to a central computer which would calculate the charge according to the
intersection and the time of day and add it to the car’s bill”.
In the 1960s and 1970’s, free flow tolling was tested with fixed transponders at the
undersides of the vehicles and readers, which were located under the surface of the
highway.
Norway has been the world’s pioneer in the widespread implementation of this
technology. ETC was first introduced in Bergen, in 1986, operating together with
traditional tollbooths. In 1991, Trondheim introduced the world’s first use of
completely unaided full-speed electronic tolling. Norway now has 25 toll roads
operating with electronic fee collection (EFC), as the Norwegian technology is called
(see AutoPASS). In 1995, Portugal became the first country to apply a single,
universal system to all tolls in the country, the Via Verde, which can also be used in
parking lots and gas stations. The United States is another country with widespread
use of ETC in several states, though many U.S. toll roads maintain the option of
manual collection.
Enforcement is accomplished by a combination of a camera which takes a picture of
the car and a radio frequency keyed computer which searches for a drivers
window/bumper mounted transponder to verify and collect payment. The system
sends a notice and fine to cars that pass through without having an active account or
paying a toll.
Factors hindering full-speed electronic collection include significant non-participation,
entailing lines in manual lanes and disorderly traffic patterns as the electronic- and
manual- collection cars “sort themselves out” into their respective lanes; problems
with pursuing toll evaders; need, in at least some current (barrier) systems, to
confine vehicles in lanes, while interacting with the collection devices, and the
dangers of high-speed collisions with the confinement structures; vehicle hazards to

toll employees present in some electronic-collection areas; the fact that in some
areas at some times, long lines form even to pass through the electronic-collection
lanes; and costs and other issues raised when retrofitting existing toll collection
facilities. Unionized toll collectors can also be problematic.

3. AUTOMATION OF TOLL GATE AND VEHICLE
TRACKING
Toll gate Automation and Vehicle Tracking is designed to automatically keep
track of the vehicle's movement, record the time and the details like Owner's name,
date of registration, vehicle model etc. This system is very useful for automatic
vehicle tracking, time management and also for automation of Toll gate. This paper
explains the implementation of Toll Gate Automation which is a step towards
improving the Tracking & monitoring of vehicles, traveling in predetermined routes. In
this system, a computerized system automatically identifies an approaching vehicle
and records the vehicle number & Time. If the vehicle belongs to the authorized
person/group, it automatically opens the Toll Gate and a predetermined amount is
automatically deducted from its account.
Automated vehicle identification (AVI) is the process of determining the
identity of a vehicle subject to tolls. The majority of toll facilities record the passage
of vehicles through a limited number of toll gates. At such facilities, the task is then to
identify the vehicle in the gate area.
Some early AVI systems used barcodes affixed to each vehicle, to be read
optically at the toll booth. Optical systems proved to have poor reading reliability,
especially when faced with inclement weather and dirty vehicles.
Most current AVI systems rely on radio-frequency identification, where an
antenna at the toll gate communicates with a transponder on the vehicle via
Dedicated Short Range Communications (DSRC). RFID tags have proved to have
excellent accuracy, and can be read at highway speeds. The major disadvantage is
the cost of equipping each vehicle with a transponder, which can be a major start-up
expense, if paid by the toll agency, or a strong customer deterrent, if paid by the
customer.
To avoid the need for transponders, some systems, notably the 407 ETR
(Electronic Toll Route) near Toronto, use automatic number plate recognition. This
allows customers to use the facility without any advance interaction with the toll
agency. The disadvantage is that fully automatic recognition has a significant error
rate, leading to billing errors and the cost of transaction processing can be
5
Research Report Automation of Toll gate and Vehicle Tracking
significant. Systems that incorporate a manual review stage have much lower error
rates, but require a continuing staffing expense.
3.1. Automatic vehicle Identification using RFID:
This system has really helped a lot in reducing the heavy congestion caused
in the metropolitan cities of today. It is one of the easiest methods used to organize
the heavy flow of traffic. When the car moves through the toll gate on any road, it is
indicated on the RFID reader that it has crossed the clearing. The need for manual
toll based systems is completely reduced in this methods and the tolling system
works through RFID. The system thus installed is quite expedient reducing the time
and cost of travelers since the tag can be deciphered from a distance.
Fig3.Toll gate automation using RFID
6
Research Report Automation of Toll gate and Vehicle Tracking
The people traveling through this transport medium do not need anything else
to get on a highway; instead the RFID tag carried by their vehicle does every thing. A
commuter traveling through this medium gets to know how much amount has been
paid and how much money is left in the tag. It does not require the person to carry
cash with him to pay the toll gate all the time. The long queue waiting for their turn is
reduced, which in-turn reduces the consumption of fuel. The RFID toll payment
systems are really used in preventing trespassing on borders. The software solution
developed can ensure a smooth running of vehicles without any need for further
development. The software controlling these RFID tags and readers is easy to
implement.
Here Basic idea is to develop the automatic challan system that can check for
signal break by any vehicle. The RFID Reader reads the information like vehicles no.
and automatically sends a report to the owner of vehicles and simultaneously
information is given on the site itself through LCD.

3.1.1Introduction to RFID
Radio-frequency identification (RFID) is an automatic identification method,
relying on storing and remotely retrieving data using devices called RFID tags or
transponders. The technology requires some extent of cooperation of an RFID
reader and an RFID tag.
An RFID tag is an object that can be applied to or incorporated into a product,
animal, or person for the purpose of identification and tracking using radio waves.
Some tags can be read from several meters away and beyond the line of sight of the
reader.

Research Report Automation of Toll gate and Vehicle Tracking
What is RFID?
A basic RFID system consists of three components:
a) An antenna or coil
b) A transceiver (with decoder)
c) A transponder (RF tag)
Antenna
The antenna emits radio signals to activate the tag and read and write data to
it. Antennas are the conduits between the tag and the transceiver, which controls the
system's data acquisition and communication. Antennas are available in a variety of
shapes and sizes; they can be built into a door frame to receive tag data from
persons or things passing through the door, or mounted on an interstate tollbooth to
monitor traffic passing by on a freeway. The electromagnetic field produced by an
antenna can be constantly present when multiple tags are expected continually. If
constant interrogation is not required, a sensor device can activate the field.
Fig5.Antenna
RF Transceiver:
The RF transceiver is the source of the RF energy used to activate and power
the passive RFID tags. The RF transceiver may be enclosed in the same cabinet as
the reader or it may be a separate piece of equipment. When provided as a separate
8
Research Report Automation of Toll gate and Vehicle Tracking
piece of equipment, the transceiver is commonly referred to as an RF module. The
RF transceiver controls and modulates the radio frequencies that the antenna
transmits and receives. The transceiver filters and amplifies the backscatter signal
from a passive RFID tag.
Transponder
An RFID tag is comprised of a microchip containing identifying information
and an antenna that transmits this data wirelessly to a reader. At its most basic, the
chip will contain a serialized identifier, or license plate number, that uniquely
identifies that item, similar to the way many bar codes are used today. A key
difference, however is that RFID tags have a higher data capacity than their bar code
counterparts. This increases the options for the type of information that can be
encoded on the tag, including the manufacturer, batch or lot number, weight,
ownership, destination and history (such as the temperature range to which an item
has been exposed).
Fig6. RFID tag
3.2. Automatic number plate recognition
ANPR is a special surveillance tool specially designed for the recognition of
license plates of vehicles. It is based on optical character recognition, which enables
the system to capture the alphanumeric characters on the number plate of a vehicle.
With the alarming increase in demand for various security based products, the ANPR
finds application in many industries such as the police forces, traffic management, or
highway and toll management systems. The system uses infrared lights, to take
9
Research Report Automation of Toll gate and Vehicle Tracking
images at any time of the day. These pictures are then sent and processed in the
system software, which in turn releases usable/readable data.
BGIL offers the ANPR for the automatic identification of a vehicle by capturing the
image of the license plate, and making its data available.
The system finds application in areas where
1. There has to be a control in vehicle access
2. Where there is need for monitoring traffic violations
3. Where there are automated toll gates
4. On weigh bridges
5. At vehicle test stations
6. Police departments
There are two major steps involved in the ANPR:
Number Plate Extraction: - In many cases, the number plate/license plate of a
vehicle is not affixed in the prescribed location. The Number Plate Extraction tool
automatically analyzes an image of the vehicle and locates the position of the license
plate and extracts the same and stores it.
Number Plate Reading: - Once the Number Plate Extraction extracts the license
plate from an image of the vehicle, this is passed to the Number Plate Reading
module that reads the numbers and characters on the license plate and passes it
onto a computer. This module can be integrated with a database for further
functionalities.

3.2.1 System architecture
Receiving end This system is designed to automatically open the toll gate whenever there is registered vehicle within the Toll Gate Zone. The figure below shows the receiver end of the system.
11
Research Report Automation of Toll gate and Vehicle Tracking
Fig8.Receiver end of automation of toll gate
The infrared signal (which contains the vehicle’s registration number in RC-5)
transmitted by the moving vehicle is received by the IR receiver. The RC-5 coded
vehicle registration number is decoded using micro-controller IC. The micro
controller IC inherits a smart RC-5 decoder program, which is capable of decoding
all the RC-5 signals. This IC sends the decoded signal to the driver stage. Channel
amplifier provides the amplification to the 8 channel received IR signal. The signal
must be elevated to sufficient level, such that it can be fed to the next stage without
any load effect. Buffer section provides a stronger current path to the decoded
signal and also to isolate the driver section and PC from the rest of the circuit. Toll
Gate Motor Controller section acts as an electronic switch and drives the Gate
Open/Shut Motor. When it senses the OK signal from the PC (after confirming that
the vehicle has current status clear), driver section switches the motor and thus toll
gate opens. The PC software recognizes the decoded vehicle registration number
coming out of the buffer and starts scanning its database for the details. After
fetching the details, it shows it in standard fashion on the screen for operator’s
knowledge. It also checks the ‘Current Status’ of the vehicle. If the vehicle is black
listed by any authority, then it will be marked as ‘blocked’, otherwise it will be marked
as ‘Clear’. If the Current Status is ‘blocked’, then the system immediately alerts the
concerned authority by sounding a siren and shuts the gate if it is open. If the current
status is ‘clear’, then the system will order the Toll Gate Motor Controller section to
open the door. All these interaction are carried out through interface circuit, which
sits next to the PC’s port.
Transmitting End
The figure below shows the transmitting end of the system.
Fig9.Block diagram of transmitter end
12
Research Report Automation of Toll gate and Vehicle Tracking
IR ID chip is the heart of the IR transmitter, as it contains the vehicle’s registration
number. Every IR transmitter fitted besides the number plate, is implanted with one
IR ID chip which stores the vehicle’s registration number. This output is further
encoded for security reason. After the encoding, theRC-5 encoded signal is fed to
the multiplexer, this in result sends the encoded signal to the modulator for
frequency modulation to prepare the signal for transmission. Every vehicle which
moves on the road has this RF transmitter besides its number plate. This transmitter
continuously transmits the radio frequency signal towards its moving direction
through the antenna.
Toll Gate Control Room Unit
The figure below show the block diagram of vehicle’s transmitter.
Fig10.Block Diagram of Vehicle’s Transmitter
The remote control receiver fitted outside the control unit senses and accepts the
signal transmitted by the remote control transmitter and sends these signals to the
computer placed inside the control room for getting the full details of the vehicle,
such as owner’s name, registration number, type of vehicle, model etc.
The remote control transmitter transmits different combination of pulses(code word)
to the receiver using Pulse Code Modulation. Different set of transmitters use
different combinations of this code word. This makes vehicle a secured transmitter,
which can transmit only its registration number and not any other vehicle’s. The
pulse code word is generated by the remote control transmitter IC. In this IC, each
transmitted code word is assumed to be made of 12 binary digits. Out of these 12
bits, 4 bits are address bits and 6 bits are command bits. The transmitted code word
is received by the control room receiver and after receiving the signal, receiver will
13
Research Report Automation of Toll gate and Vehicle Tracking
check if the transmitted address in the code word matches the address of the
receiver. If the address in the code word matches the address of the receiver, the
receiver will accept the command word.
4. TECHNOLOGIESElectronic toll collection systems rely on four major components: automated vehicle
identification, automated vehicle classification, transaction processing, and violation
enforcement.
The four components are somewhat independent, and, in fact, some toll
agencies have contracted out functions separately. In some cases, this division of
functions has resulted in difficulties. In one notable example, the New Jersey E-
ZPass regional consortium's Violation Enforcement contractor did not have access to
the Transaction Processing contractor's database of customers. This, together with
installation problems in the automated vehicle identification system, led to many
customers receiving erroneous violation notices, and a violation system whose net
income, after expenses, was negative, as well as customer dissatisfaction.
4.1. Automated vehicle identification
Some highways, such as Ontario’s Highway use automatic number plate recognition
14
Research Report Automation of Toll gate and Vehicle Tracking
Automated vehicle identification (AVI) is the process of determining the identity of
a vehicle subject to tolls. The majority of toll facilities record the passage of vehicles
through a limited number of toll gates. At such facilities, the task is then to identify
the vehicle in the gate area.
Some early AVI systems used barcodes affixed to each vehicle, to be read optically
at the toll booth. Optical systems proved to have poor reading reliability, especially
when faced with inclement weather and dirty vehicles.
Most current AVI systems rely on radio-frequency identification, where an antenna at
the toll gate communicates with a transponder on the vehicle via Dedicated Short
Range Communications (DSRC). RFID tags have proved to have excellent
accuracy, and can be read at highway speeds. The major disadvantage is the cost of
equipping each vehicle with a transponder, which can be a major start-up expense, if
paid by the toll agency, or a strong customer deterrent, if paid by the customer.
To avoid the need for transponders, some systems, notably the 407 ETR (Electronic
Toll Route) near Toronto, use automatic number plate recognition. Here, a system of
cameras captures images of vehicles passing through tolled areas, and the image of
the number plate is extracted and used to identify the vehicle. This allows customers
to use the facility without any advance interaction with the toll agency. The
disadvantage is that fully automatic recognition has a significant error rate, leading to
billing errors and the cost of transaction processing (which requires locating and
corresponding with the customer) can be significant. Systems that incorporate a
manual review stage have much lower error rates, but require a continuing staffing
expense.
A few toll facilities cover a very wide area, making fixed toll gates impractical. The
most notable of these is a truck tolling system in Germany. This system instead
uses Global Positioning System location information to identify when a vehicle is
located on a tolled Autobahn. Implementation of this system turned out to be far
lengthier and more costly than expected.
As smart phone use becomes more commonplace, some toll road management
companies have turned to mobile phone apps to inexpensively automate and
expedite paying tolls from the lanes. One such example application is Alabama
Freedom Pass mobile, used to link customer accounts at sites operated by American
15
Research Report Automation of Toll gate and Vehicle Tracking
Roads LLC. The app communicates in real time with the facility transaction
processing system to identify and debit customer accounts or bill a major credit card.
4.2. Automated vehicle classification
Automated vehicle classification is closely related to automated vehicle identification
(AVI). Most toll facilities charge different rates for different types of vehicles, making
it necessary to distinguish the vehicles passing through the toll facility.
The simplest method is to store the vehicle class in the customer record, and use the
AVI data to look up the vehicle class. This is low-cost, but limits user flexibility, in
such cases as the automobile owner who occasionally tows a trailer.
More complex systems use a variety of sensors. Inductive sensors embedded in the
road surface can determine the gaps between vehicles, to provide basic information
on the presence of a vehicle. Treadles permit counting the number of axles as a
vehicle passes over them and, with offset-treadle installations, also detect dual-tire
vehicles. Light-curtain laser profilers record the shape of the vehicle, which can help
distinguish trucks and trailers.
4.3. Transaction processing
Transaction processing deals with maintaining customer accounts, posting toll
transactions and customer payments to the accounts, and handling customer
inquiries. The transaction processing component of some systems is referred to as a
"customer service center". In many respects, the transaction processing function
resembles banking, and several toll agencies have contracted out transaction
processing to a bank.
Customer accounts may be postpaid, where toll transactions are periodically billed to
the customer, or prepaid, where the customer funds a balance in the account which
is then depleted as toll transactions occur. The prepaid system is more common, as
the small amounts of most tolls makes pursuit of uncollected debts uneconomic.
Most postpaid accounts deal with this issue by requiring a security deposit,
effectively rendering the account a prepaid one.
16
Research Report Automation of Toll gate and Vehicle Tracking
4.4. Violation enforcement
A violation enforcement system (VES) is useful in reducing unpaid tolls, as an
unmanned toll gate otherwise represents a tempting target for toll evasion. Several
methods can be used to deter toll violators.
Police patrols at toll gates can be highly effective. In addition, in most jurisdictions,
the legal framework is already in place for punishing toll evasion as a traffic
infraction. However, the expense of police patrols makes their use on a continuous
basis impractical, such that the probability of being stopped is likely to be low enough
as to be an insufficient deterrent.
A physical barrier, such as a gate arm, ensures that all vehicles passing through the
toll booth have paid a toll. Violators are identified immediately, as the barrier will not
permit the violator to proceed. However, barriers also force authorized customers,
which are the vast majority of vehicles passing through, to slow to a near-stop at the
toll gate, negating much of the speed and capacity benefits of electronic tolling.
Automatic number plate recognition, while rarely used as the primary vehicle
identification method, is more commonly used in violation enforcement. In the VES
context, the number of images collected is much smaller than in the AVI context.
This makes manual review, with its greater accuracy over fully automated methods,
practical. However, many jurisdictions require legislative action to permit this type of
enforcement, as the number plate identifies only the vehicle, not its operator, and
many traffic enforcement regulations require identifying the operator in order to issue
an infraction.
An example of this is the vToll system on the Illinois Tollway, which requires
transponder users to enter their license plate information before using the system. If
the transponder fails to read, the license plate number is matched to the transponder
account, and the regular toll amount is deducted from the account rather than a
violation being generated.[27] If the license plate can't be found in the database, then
it is processed as a violation. An interesting aspect of Illinois' toll violation system is a
7 day grace period, allowing toll way users to pay missed tolls online with no penalty
the 7 days following the missed toll.

5. OVERVIEW
In some urban settings, automated gates are in use in electronic-toll lanes, with
5 mph (8 km/h) legal limits on speed (and 2 to 3 times that as practical limits even
with practice and extreme concentration) in other settings, 20 mph (35 km/h) legal
limits are not uncommon. However, in other areas such as the Garden State
Parkway in New Jersey, and at various locations in Florida, Pennsylvania, Delaware,
and Texas, cars can travel through electronic lanes at full speed. Illinois' Open Road
Tolling program features 274 contiguous miles of barrier-free roadways, where I-
PASS or E-ZPass users continue to travel at highway speeds through toll plazas,
while cash payers pull off the main roadway to pay at tollbooths. Currently over 80%
of Illinois' 1.4 million daily drivers use and I-PASS
18
Research Report Automation of Toll gate and Vehicle Tracking
Enforcement is accomplished by a combination of a camera which takes a
picture of the car and a radio frequency keyed computer which searches for a
driver’s window/bumper mounted transponder to verify and collect payment. The
system sends a notice and fine to cars that pass through without having an active
account or paying a toll.
Factors hindering full-speed electronic collection include significant non-
participation, entailing lines in manual lanes and disorderly traffic patterns as the
electronic- and manual- collection cars "sort themselves out" into their respective
lanes; problems with pursuing toll evaders; need, in at least some current (barrier)
systems, to confine vehicles in lanes, while interacting with the collection devices,
and the dangers of high-speed collisions with the confinement structures; vehicle
hazards to toll employees present in some electronic-collection areas; the fact that in
some areas at some times, long lines form even to pass through the electronic-
collection lanes; and costs and other issues raised when retrofitting existing toll
collection facilities. Unionized toll collectors can also be problematic.
Even if line lengths are the same in electronic lanes as in manual ones,
electronic tolls save registered cars time: eliminating the stop at a window or toll
machine, between successive cars passing the collection machine, means a fixed-
length stretch of their journey past it is traveled at a higher average speed, and in a
lower time. This is at least a psychological improvement, even if the length of the
lines in automated lanes is sufficient to make the no-stop-to-pay savings insignificant
compared to time still lost due waiting in line to pass the toll gate. Toll plazas are
typically wider than the rest of the highway; reducing the need for them makes it
possible to fit toll roads into tight corridors.
Despite these limitations, however, it is important to recognize that throughput
increases if delay at the toll gate is reduced (i.e., if the tollbooth can serve more
vehicles per hour). The greater the throughput of any toll lane, the fewer lanes
required, so expensive construction can be deferred. Specifically, the toll-collecting
authorities have incentives to resist pressure to limit the fraction of electronic lanes in
order to limit the length of manual-lane lines. In the short term, the greater the
fraction of automated lanes, the lower the cost of operation (once the capital costs of
automating are amortized). In the long term, the greater the relative advantage that
registering and turning one's vehicle into an electronic-toll one provides, the faster
19
Research Report Automation of Toll gate and Vehicle Tracking
cars will be converted from manual-toll use to electronic-toll use, and therefore the
fewer manual-toll cars will drag down average speed and thus capacity.
In some countries, some toll agencies that use similar technology have set up
(or are setting up) reciprocity arrangements, which permit one to drive a vehicle on
another operator's tolled road with the tolls incurred charged to the driver's toll-
payment account with their home operator. An example is the United States E-ZPass
tag, which is accepted on toll roads, bridges and tunnels in fourteen states
from Illinois to Maine.
Fig11.E-TAG lane on the Second Severn Crossing, Wales
In Australia, the e-TAG device is accepted at all tolled motorways. A toll is debited to
the customer's account with their tag provider. Some toll road operators – including
Sydney's Sydney Harbour Tunnel, Lane Cove Tunnel, and West link M7,
Melbourne'sCityLink and East link, and Brisbane's Gateway Motorway – encourage
use of such tags, and apply an additional vehicle matching fee to vehicles without a
tag.
A similar device in France, called Liber-T for light vehicles and TIS-PL for HGVs, is
accepted on all toll roads in the country.
In Brazil, Sem Parar/Via-Fácil allows customers to utilize in more than 1,000
lanes in the states of São Paulo, Parana, Rio Grande do Sul, Santa Catarina, Bahia
and Rio de Janeiro. Sem Parar/Via-Fácil also allows users to enter and exit more
than 100 parking lots. There is also other systems such as via expressa, onda
livre,auto expresso that is present in the states of Rio de Janeiro, Rio Grande do Sul,
Santa Catarina, Parana and Minas Gerais.
In Pakistan, the National Database and Registration Authority is implementing
an electronic toll collection system on motorways using RFID.
20
Research Report Automation of Toll gate and Vehicle Tracking
The European Union has created the EFC-directive,[4] which attempts to standardize
European toll collection systems. Systems deployed after 1 January 2007 must
support at least one of the following technologies: satellite positioning, mobile
communications using the GSM-GPRS standard or 5.8 GHz microwave technology.
All toll roads in Ireland must support the eTolltag standard.
6. HARWARE REQUIREMENTS AND SOFTWARE REQUIREMENTS

7. ADVANTAGES AND DISADVANTAGES
7.1. Advantages using RFID
No "line of sight" requirements: Bar code reads can sometimes be limited or
problematic due to the need to have a direct "line of sight" between a scanner
and a bar code. RFID tags can be read through materials without line of sight.
More automated reading: RFID tags can be read automatically when a tagged
product comes past or near a reader, reducing the labor required to scan
product and allowing more proactive, real-time tracking.
Improved read rates: RFID tags ultimately offer the promise of higher read
rates than bar codes, especially in high-speed operations such as carton
sortation.
Greater data capacity: RFID tags can be easily encoded with item details
such as lot and batch, weight, etc.
"Write" capabilities: Because RFID tags can be rewritten with new data as
supply chain activities are completed, tagged products carry updated
information as they move throughout the supply chain.

7.2. Disadvantages using RFID
o Some common problems with RFID are reader collision and tag
collision. Reader collision occurs when the signals from two or more
readers overlap.
o The tag is unable to respond to simultaneous queries. Systems must
be carefully set up to avoid this problem.
o Tag collision occurs when many tags are present in a small area; but
since the read time is very fast, it is easier for vendors to develop
systems that ensure that tags respond one at a time.
o The major disadvantage is the cost of equipping each vehicle with a
transponder, which can be a major start-up expense, if paid by the toll
agency, or a strong customer deterrent, if paid by the customer.
7.3. Advantages of using Automatic Number Plate Recognition
ANPR identifies suspect vehicles that may not normally attract police
attention.
Unlicensed or uninsured vehicles are likely to be seized on the spot by
ANPR-equipped officers.
It can be used to gather intelligence on known criminals, and for running
pro-active operations using dedicated Roads Policing intercept teams.
This allows customers to use the facility without any advance interaction with
the toll agency
7.4. Disadvantages of using Automatic Number Plate Recognition
The disadvantage is that fully automatic recognition has a significant error
rate, leading to billing errors and the cost of transaction processing can be
significant. Systems that incorporate a manual review stage have much lower
error rates, but require a continuing staffing expense.

8. APPLICATION AND FUTURE DEVELOPMENTS
This system can be use to keep track of certain important details of the vehicle such
as time of arrival and departure of the vehicle, number of round trips each vehicle
has made, the route taken between source and destination and can be used to trace
the stolen vehicle.
8.1. Future developments This can be extended to handle more number of vehicles, as the number of
registered users may increase. The present set up in most countries is that, only
one vehicle passes the toll gate at a given time and the vehicles enter the toll gate in
a queue. Sophisticated setup can be built where in two or more vehicles can enter a
toll gate at a time and still the system recognizes the valid users and differentiates
the vehicles which are entering the toll gate parallelly. This increases the complexity
of the entire system but at the same time increases the traffic handling capacity and
saves time. The ID of the vehicle can be made more sophisticated to increase the
security and reducing the risk of tampering. The registered user can use a pre-paid
or post paid account by using a smart card.
He/she can insert the card into the card reader placed on the dash board of
the vehicle so that it can communicate with the IR interface at the toll gate. The
system identifies the registered vehicle from the user information stored on the smart
card and if he is a valid user, then the gate will automatically open and a pre-
determined amount will be deducted from the account. Once the amount gets
emptied, the user can always deposit the money and keep the account active. A
facility can be introduced wherein the vehicle owner can pay the ‘toll fee’ through his
credit card by mentioning in the application form. Whenever the vehicle owner
comes across a toll gate, the system detects the vehicle and charges the fee to his
credit card and allows him to pass the gate without interrupting him. This would
make the owner save his time and energy. The toll operators collect money only

from the un-registered users and hence the amount of liquid cash collected in the toll
gate is lesser. This reduces the risk of loosing more money in case of theft of the toll
collecting office on the highway. GPS receivers can be used to get the current
geographical position of the vehicles. Various sensors can be used to monitor critical
parameters like engine oil level, temperature level etc.
9. CONCLUSION
Toll gate automation using RFID has been a successful project with all its hits
and pits. Radio Frequency Identification (RFID) provides a low-cost solution to read
passive RFID transponder tags. This RFID can be used in a wide variety of hobbyist
and commercial applications, including access control, automatic identification,
robotics navigation, inventory tracking, payment systems, and car immobilization.
The RFID read the RFID tag in range and outputs unique identification code of the
tag. The data from RFID reader can be interfaced to be read by microcontroller or
PC.
To avoid the need for transponders, some systems, notably the 407 ETR
(Electronic Toll Route) near Toronto, use automatic number plate recognition. This
allows customers to use the facility without any advance interaction with the toll
agency.
In this paper an overview of “Automation of Toll Gate and Vehicle Tracking” using
RFID and Automatic number plate recognition has been presented. By adapting this
technology, various applications like Traffic Management Process, Vehicle
Movement Tracking and Stolen Vehicle Detection could be implemented. Using
model based approach; this could be implemented and tested using MATLAB and
Simulink.
