• 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.
INTRODUCTION

BACKGROUND SITUATION OF PROMOTING ITS
 To Solve Social
Problems caused by Road
 To activate the
Economy
 To reach an Advanced
Information and Tele
communication Society
 To Co-ordinate different
Transport Modes

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
Electronic Fee Collection(EFC) will
operate over DSRC. It is a sub-set of
the RFID - technology (Radio-
Frequency Identification).

Continuous Air interface
Long and Medium range
(CALM)provides continuous
communications between a
vehicle and the roadside
using a variety of
communication media,
including cellular and infra-
red links.
• Continuous Air interface
Long and Medium range
(CALM) :

(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 +
dedicated short range tag.

(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
and low volume traffic.

Radar and acoustic sensors are also used for detecting vehicles in
the roadway.

(4) Video Vehicle Detection :
Video vehicle detection
(VVD) is the One of the
most widely used method.
Video detection is an
image processor. It
consists of a
microprocessor-base CPU
and software that analyzes
video images.

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. Courtesy:HowStuffWorks

What are the benefits of using FASTag?
Environmental benefit Social benefit Economic benefit
• Reduced air pollution
• Reduced use of paper
•Reduced toll payment
hassles
•Analytics for better
highway management
• Reduced effort in
management at toll plaza
• Reduced effort in
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:

2) Variable Message Service:
• Variable message signs (VMS) are traffic control devices used to provide
motorists en- route traveler information.

• A traffic enforcement
camera system, consisting
of a Camera and a
Vehicle-monitoring
device, is used to detect
and identify vehicles
disobeying Speed Limit
(3) Automatic Road Enforcement :

(4) Collision Avoidance Systems :
Intersection Collision Warning Obstacle Detection
Lane Change assistance Lane Departure Warning

•Road Weather
•Next Bus
•Traveler Times
•Emergency Alerts
•Alternate Routes

(6) Emergency Management Services :
Emergency Management Services are greatly enhanced by
traffic control centres that continually monitor roadway conditions.
