4. This project is based on radio
frequency Identification.
It is a technology for toll tax
collection that permits vehicles to
pay highway toll electronically.
A RFID tag for the vehicles having
a unique UID code is used.
This automation has replaced live
attendants at toll stations that
collect fees manually.
5.
Toll agencies are interested in
developing these tags and readers
because they can simplify the
tolling system.
6.
RFID tags are electronically
encoded with unique identification
numbers (UID codes) is get mounted
on vehicle’s front side.
RF transmitter-receiver pair is
located along the road, in overhead
structures or apart of the toll
collection booth.
7.
As the vehicle approaches a tag reader
site, the roadside antenna emits a signal
that is reflected back by the tag located
on the windshield.
The identification number is read and
is sent to a roadside reader unit. A
central computer uses the code to
identify the account and the cost is
deducted from the customer’s account.
11. LED display is used
as the display unit in
this system just for the
acknowledgement of
vehicle number and the
balance amount of the
Rf tag. Depending on
this acknowledgement
, an electronic switch
is made open or close.

13.
A RF passive card is an RFID tag that
does not contain a battery; the power is
supplied by the reader.
When radio waves from the reader
are encountered by a passive RFID tag,
the coiled antenna within the tag forms
a magnetic field. The tag draws power
from it, energizing the circuits in the tag
14.
The tag then sends the information
encoded in the tag's memory. The
information encoded in the tag’s
memory is a digital code which is
called UID code. It is distinct for every
vehicle’s tag.
20. Makes traveling more convenient, reduces
travel times
Saves fuel
Reduces auto emissions
Reduces wait time at toll booths
Save money through individual and
business discounts
21. Increase highway capacity
Processes 250 – 300% more
vehicles per lane, reducing
delays and traffic congestion
22.
There are Undetected Incorrect Reads
– referring to the incorrect read of a tag
that the registration hardware or
software does not catch. This scenario
constitutes either a “free ride” for the
motorist, or an undeserved fine for
failure to pay – which can be a hefty
price.
23.
Theft – the tags are, in essence,
“electronic money” and therefore there
will be motivation to steal them.
Specially-designed tags that are
permanently affixed to the windshield
have been created to deter anyone from
trying to remove it without damaging
the tag.
24. If this technology is adopted in every
vehicle then in future , it will be easier to
cross-check the vehicle for many important
reasons like theft vehicle, toll tax
identification, tracing of vehicles used in
criminal activities & many more.
