3. Traffic congestion-insufficient road development-
growing number of vehicles.
Low speed, increased accident rates, increased fuel
consumption, and increased pollution
These explore the concepts that treat highway systems
and the vehicles that use them as integrated system.
Among them is the concept of Intelligent Transportation
Systems.

4. International program aimed at using advanced technology
for improving the efficiency , safety and environmental
impact of land transportation.
It is the Incorporation of information technologies and
advances in electronics into all parts of the transportation
network.
It help drivers to navigate, avoid traffic holdups and avoid
collisions
4
8. It is a digital communication system.
It provide real time road traffic information to the drivers
via car navigation system
Information is transmitted in the direction of traffic
flow from beacons
Steps in the operation of VICS
1.Collecting information
2.Processes and edits the collected information
3.Providing information

ITS SYSTEMS
10. VICS provides three kinds of displays
Map Display
Simple Graphic Display
Text Display
10
11. It provide information, warning and operational support
for accident prevention by using use radio communication
between road and vehicle
Smart way enables a wide range of information exchange
among all of ITS users
It require functions capable of sensing road-environment
data
functions for generating guidance from road-environment
data and road-to-vehicle communication
11
13. AHS ROADSIDE PROCESSING EQUIPMENT
Image-processing subsystem: Use image processing
to detect road obstacles and other vehicles, and to observe traffic
Road-to-Vehicle Communications
Roadside Equipment Networks
13
14. It provide drivers with real-time travel and traffic
information
Information about delays
Help for optimal route selection
There are three key steps to the provision of real-
time traffic information:
o collection
o processing
o dissemination
14
16. Focus on traffic control devices
Adaptive traffic signal control: to avoid bad signaling
Ramp metering :to avoid vehicles entering into
highway
Three ATMS elements
oCollection data team
oSupport system
oReal time traffic control system
16
18. APTS include applications such as automatic
vehicle location (AVL)
Each vehicle report their current location
This system report the arrival and departure status
of buses and trains
18
Advanced Public Transportation Systems(APTS)
20. Portable GPS car navigation systems have become must
have today for most drivers today
It helps the driver to locate his position, while guiding
him to his destination.
The map provides a graphical
picture of area
It also provide turn-by-turn
directions, visually as well as
in form of spoken instructions
20
ADVANCES IN NAVIGATION SYSTEMS:
21. ELECTRONIC TOLL COLLECTION SYSTEM:
21
An application of
electronic signature
detection to passenger
and commercial
vehicle traffic for the
purpose of collecting
tolls
Allowing motorists to
pass through the
system at highway
speeds
Transponder: radio
frequency
identification unit that
transmits radio signals
22. The three user services
offered by this system are:
Provision of Driving and
Road Condition Information
Danger Warning
Assistance for driving
22
24. o Consisting of a camera and a vehicle-monitoring
device
o Used to detect and identify vehicles disobeying a
speed limit or some other road legal requirement
Speed cameras
Red light cameras
Bus lane cameras
Level crossing cameras
Double white line cameras
Turn cameras at intersections

26. Reducing traffic congestion;
Smoothening the traffic flow;
Reducing traffic accidents;
Improving safety;
Enhancing the mobility of travelers, especially the
elderly and disabled;
Reducing the use of energy;
Reducing fuel consumption;
Reducing pollution;
Reducing capital and operating costs;
Increasing the viability of public transportation;
Responding more effectively to incidents;
Increasing the ease and convenience of travel
26
28. Difficult to use in mixed traffic.
Preliminary difficulties in understanding.
ITS equipments costly.
The control system software could be hacked by
hackers.
28
29. ITS represent the next step in the evolution of a nation's
entire transportation system
Traffic congestions, rate of road accidents, wastage of
fuels are decreased to a large extend
Transportation has become a safer and efficient mode
Hence with much more interest and advanced research
in the field of I T S, it can be implemented in our
country and can prove to be the solution of the traffic
problems including traffic congestion, air pollution and
traffic accidents.
This system will give a high progress in the
devolvement of our country
