INTRODUCTION
ITS is a comprehensive system which can prepare safesmooth and pleasant environment for road traffic.
The fundamental element for ITS is communicationtechnology between road infrastructure and vehicle.
ITS comprises of broad range wireless and wirelinecommunication based information.
ITS utilize existing roadways more efficiently to reducecongestion, delay, minimize accidents and improve airquality.

ITS provide tools for skilled transportation professionals tocollect and analyze the data about the performance of the
system during peak hours.
Thus ITS is an international program intended to improve
surface transportation system through advanced
technologies.

TRAFFIC PROBLEMS
Traffic congestion and delay.
Inadequate public transportation facilities, which runbehind scheduled, causing inconvenience to public.
Shortage of man power.
Increase in air and noise pollution due to increase in
number of vehicles.

Acute parking problem in urban areas.
Non-cooperation from public for any new system or
changes.
High accident rates due to varying speed of vehicles and
lack of discipline among road users.
Absence of effective monitoring and prevention of traffic
violation.

ADVANCED PUBLIC TRANSPORTATION
SYSTEM
APTS is a technology that increase the efficiency and
safety of public transportation system.
The goal of APTS is to provide more information to public
to make effective decision and to increase travelers
convenience and rider ship.
Basically this system helps to smoothen out public
transportation related problems.

ADVANCED TRAVELER INFORMATION
SYSTEM
ATIS is a new technology helps in providing accurate and
timely information to travelers.
They deliver data directly to travelers empowering them to
make better choices.
This system helps in optimizing the transportation planning
process.

ADVANCED TRAFFIC MANAGEMENT
SYSTEM
Monitor the flow of traffic making appropriate decision in
a timely manner.
Employs inexpensive detectors, cameras and
communication system to control the flow of traffic.
Optimize signal timings on major arterials.

AUTOMATED HIGHWAY SYSTEM
AHS is a specially equipped highway lane, where the
vehicles are automatically controlled by the system, not bythe driver.
The system helps in keeping the vehicle in the same lane.
The AHS lanes and vehicles which operate on them are
likely to have special sensors, computers and
communication devices to permit automated control.

INCIDENT MANAGEMENT SYSTEM
They offer real time information about traffic conditions
through variable message sign to warn accidents or other
delays.
Variable message sign is a board which provideinformation to the motorist of the upcoming hazards.
Enables authorities to identify and respond to vehiclecrashes or breakdowns with the most appropriate andtimely emergency services, thereby minimizing recoverytime.

ELECTRONIC TOLL COLLECTION
SYSTEM
ETC is a system by which drivers can pay tolls withouthaving to stop at a toll booth.
The collection of fees is performed electronically by way
of equipment installed in the vehicle and sensors at toll
location.
ETC is based on vehicle roadside communication system.

ADVANCED WARNING SYSTEM
This system warns the present accident to be caused when
traffic slows down abruptly due to road conditions.
The information given to the driver when the vehicles
come closer either from front or back is conveyed through
AWS which helps in preventing road crashes.

VEHICLE INFORMATION AND
COMMUNICATION SYSTEM
In this system, the drivers are provided with real timeinformation on the traffic conditions
They update all the road users about the traffic conditionsand other information like congestion, jams, roadblocks,
pollution levels etc.
The information is given via FM band or through roadmaps quickly showing the traffic conditions in surroundingareas.The driver can use this information to select the bestroute by using in vehicle monitor.

VIDEO TRANSMISSION
This system is used for detecting unauthorized vehicles on
restricted corridors and parking areas.
Vehicles with speed violations can be captured along with
registration numbers.

NECESSITY FOR USING ITS
Provides novel application by smart technology.
Systematically employs advanced technologies in the field
of transportation to enhance benefits for road users.
Reduction in road crashes.
Improves the existing transportation services throughinterconnected embedded technologies.

ITS IN INDIA
In India 70 state transport undertakings which togetherown and operate 1,13,000 buses and provide mobility to 65million passengers a day, across the length and breadth of
the country.
The most important task of ITS India will be thedissemination of ITS knowledge and imparting training fornew professionals.In 1980s number of developedcountries started using advanced system to control andregulate traffic.This is still to develop in India to suit ourlocal ambience.

The very first equipment to be used in Indian environmentwas electronic toll collection along the newly created
expressways i.e, Delhi-Noida, Ahmedabad-Mehasana and
Mumbai-Pune, which is functioning satisfactorily.
What is needed in the present context is the mind set of
policy makers to cooperate for the adaptation to the new
system.

CONCLUSION
The potential of ITS technologies in improving the
efficiency of transportation sector in India appears to be
very promising based on the experience of other countries.
A national strategic ITS plan for India is needed for the
effective development and deployment.
Some of the ITS technologies like fleet managementsystem, AWS, ETC, Incident management system can be
applied to achieve an efficient transportation system.

Since ITS technology is as old as 20 years in the world,
India will have to pick up this for updating and be on par
with developed countries in modern transportation
requirements.
