The document discusses intelligent transportation systems (ITS), which use advanced technologies like electronics, computers, communications, and sensors to provide travelers with important information and improve transportation safety and efficiency. It outlines several ITS technologies including wireless communications, vehicle detection methods, and applications such as electronic toll collection, variable message signs, automatic enforcement, collision avoidance systems, traveler information services, and emergency management. The benefits of ITS include time savings, improved safety, reduced costs and crashes, while the challenges include costs, mixed traffic difficulties, and maintenance expenses. Projected ITS infrastructure benefits from 2000-2020 include substantial savings in accidents, time, fuel, and operating costs.

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

plazas) Applications such
as

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
