3. •ITS is the integrated
application of advanced
technologies using
Electronics, Computers,
Communications, and
Advanced sensors. These
applications provide
travellers with important
information while improving
the safety and efficiency of
the transportation system.

5. INTELLIGENT TRANSPORTATION TECHNOLOGIES
(1) Wireless Communications :
• Dedicated Short-
Range
Communications
(DSRC) :
It offers communication
between the vehicle and the
roadside in specific locations (for
example toll

Collection(EFC)
plazas) Applications such
as
will
operate over DSRC. It is a sub-
set of the RFID - technology
(Radio- Frequency Identification).

7. (2) Floating Car Data/Floating Cellular Data :
• Non Real-time:
– Manual surveys.
–Video recording
and manual
search.
– In-vehicle data recording.
• Real-time:
–Automatic Number
Plate Recognition
(ANPR).
– GPS trace + mobile comms
e.g. GSM.
– Radio Signal Triangulation.
– Roadside beacon +
8. (3) Inductive loop detection :
• One or more loops of wire
are embedded under the
road & connected to a
control box.
• When a vehicle passes over
or rests on the loop,
inductance is reduced
showing a vehicle is
present.
• Benefits:
• Established Technology
• Not impacted by
environmental
conditions
• Accurate in detecting
vehicle presence
• Performs well in both high
9. Radar and acoustic sensors are also used for detecting
vehicles in
the roadway.
10. (4) Video Vehicle Detection :
Video vehicle
detection (VVD)
is the One of the
most widely used
method.

11. INTELLIGENT TRANSPORTATION APPLICATIONS
(1) Electronic Toll Collection :
• Today, most toll roads are
equipped with an
electronic toll-collection
system, like FASTag & E-
Zpass, that detects and
processes tolls
electronically.
• FASTag is a device that
employs Radio
Frequency
Identification (RFID)
technology for making
toll payments.

13. What are the benefits of using FASTag?
Environmental benefit Social benefit Economic benefit
•Reduced toll payment • Reduced effort in
• Reduced air pollution hassles management at toll plaza
• Reduced use of paper •Analytics for better • Reduced effort in
highway management monitoring centrally
1.Ease of payment – No need to carry cash for
the toll transactions, saves time
2.Near non-stop movement of vehicles leading to
lower
fuel cost.
3.Online Recharge – FASTag can be recharged
online through Credit Card / Debit Card /
NEFT/ RTGS or Net banking
4.SMS alerts for toll transactions, low balance,
etc. 5.Online Portal for customers
Other benefits are:
14. 2) Variable Message Service:
• Variable message signs (VMS) are traffic control devices used to
provide motorists en- route traveler information.
15. • A traffic
enforcement
camera system,
consisting of a
Camera and
a Vehicle-
monitoring device,
is used todetect
and identify
vehicles
disobeying Speed Limit

21. • Time Savings
• Better emergency response times and services
• Reduced Crashes and Fatalities
• Cost Avoidance
• Increased Customer Satisfaction
• Energy and Environmental Benefits
• Decreasing of probability of congestion occurrence
ADVANTAGES OF ITS :
22. DISADVANTAGES OF ITS:
• Difficult to use in mixed traffic
• Preliminary difficulties in understanding
• Equipment of ITS is costly
• High Maintenance cost
