Intelligent Transportation Systems (ITS) use advanced technologies to improve transportation efficiency and safety. ITS applications include GPS, traveler information systems, and electronic toll collection. While ITS provides benefits like reduced congestion and accidents, challenges to implementation include high costs, software hacking risks, and difficulties with mixed traffic conditions. The document discusses the definition of ITS, its applications, benefits, and challenges through examples and case studies.

3. What is Intelligent Transportation
System?
Intelligent Transportation System are advanced applications aim to
provide innovative services related to different modes of transport and
traffic management.

4. Necessity of ITS :
India is going through a period of drastic change in the transportation area
due to:
• Rapidly growing economy.
• Insufficient and inadequate public transportation system.
• Rising vehicle ownership levels.
• Traffic congestion, insufficient road development growing number of
vehicles.
• Increased accident rates.
• Increased fuel consumption and increased pollution.
• Impossible to build enough new roads or to meet the demand.

5. Applications of ITS :
1. Global positioning system.
2. Advanced traveller information system.
3. Traveller information services.
4. Automatic road enforcement.
5. Electronic toll collector.
6. Automatic passenger counter.
7. Emergency vehicle notification system.

6. Global positioning system :
A system of satellites, computers and receivers in which traffic data is
incorporated in the map, the driver can get the fastest route, can know the
position of the signals ahead, predict traffic jams, etc.

7. Advanced traveller information system.
It helps to save the travel time, reduce cost reliability, more comfort to
travellers, gives safety and security.
Travellers are provided with both static and dynamic information.
Transportation management centres respond to real-time traffic conditions,
control which lanes may be used,
traffic signal timing.

9. Benefits of ITS :
• Reduced congestion and time saving.
• Reduced fuel consumption and emissions.
• Reduced frustration.
• Reduced road accidents.
• Increased safety.
• Enhanced economic
• productivity.
• Better traffic flow.
• Greater user acceptance.

10. Difficulties in Implementing ITS :
• Difficult to use in mixed traffic.
• Preliminary difficulties in understanding.
• ITS equipment's are costly.
• The control system software could be hacked by hackers.
• An ITS may not be applicable to some scenario.
• At the traffic less areas this system will become ineffective.
• Due to heterogeneous traffic conditions leads to congestion and
overlapping of data.

17. Conclusion :
ITS already has a presence in everyone’s day-to-day mobile activities, a part
of our daily life. Inside the vehicle, for example, active support system such as
vision enhancement, lane-keeping assistance, collision warning and alertness
monitors will have an impact on driver error and fatigue. In addition, systems
such as coordinated traffic control, ramp metering, variable message signs and
traffic and incident detection systems are being implemented by infrastructure
operators to monitor road conditions and provide smooth and safe journeys.
