The document discusses electronic toll collection (ETC) systems. The key components of an ETC system include RFID tags mounted on vehicles, readers that communicate with the tags, and in-lane computers. RFID tags contain identification information and payment details. Readers detect tags as vehicles approach and verify payment. In-lane computers then deduct the correct toll from the account and open gates to allow passage. ETC systems allow cashless tolling, reduce congestion at toll plazas, and provide a more convenient driving experience.

3. What is ETC System?
The Electronic Toll
Collection (ETC)
System is a new toll
system designed to
enhance convenience
for drivers by enabling
cashless toll collection
and thus mitigating
congestion at
expressway tollgates.

4. Objectives of ETC System
• Reduce longer
waiting time in a
toll queue
• Provide traveler
ease of toll
payment
• Reduce illegal toll
gate entry

5. Components of ETC System
• RFID Tag
• Reader
• In Lane Computer

6. RFID Tags
• 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
the reader.
• Each tag contains an
identification number, data
identifying the issuing agency,
tag type, a description of the
vehicle, and other agency-
specific data.
• The RFID Tag is mounted on
windshield of vehicle.

7. RFID Tags – Basic Types
Active Tags
• Tag transmits radio signal
• Battery powered memory,
radio & circuitry
• High Read Range (100
meters)
Passive Tags
• Tag reflects radio signal
from reader
• Reader powered
• Shorter Read Range (10cm
– 5 meters)

8. 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.

9. In Lane Computer
• 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, and
approves passage or raises a
tollgate to allow the vehicle to
pass through the toll plaza.

11. Working
• As a vehicle approaches a toll plaza, the radio-
frequency (RF) 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.

12. Working

13. Advantages
• Entire process takes a matter of seconds
to complete.
• Electronic system records transaction,
including the time, date, plaza and toll
charge of each vehicle.
• Allow drivers to pass through the system
at 55 miles per hour (86 kmph).

14. Conclusion
By application of ATCS into real time we
can avoid malfunctions, time maintenance
system and long wait at toll gates can be
improved
