Intelligent Transportation Systems (ITS) utilize information and communication technology to enhance transport safety, productivity, reliability, social equity, and environmental performance. Key applications include emergency vehicle notifications, automatic road enforcement, and collision avoidance systems that autonomously take action to prevent accidents. Features of these systems involve various forms of warnings and assistance for pedestrians, lane changes, and collision prevention.

2. What is ITS?
The term Intelligent Transportation Systems (ITS) refers to information and
communication technology, applied to transport infrastructure and vehicles,
that improve transport outcomes such as:
Transport Safety
 Transport Productivity
 Travel Reliability
Social Equity
 Environmental Performance
 Network Operation Resilience

3. Applications of ITS
 Emergency Vehicle Notification Systems
 Automatic Road Enforcement
 Variable Speed Limits
 Collision Avoidance Systems
 Dynamic Traffic Light Sequence

4. Collision avoidance system/pre crash
system
 It is an automobile safety system designed to prevent or reduce the
severity of a collision.
 It uses radar ,laser and camera to detect an imminent crash.
 GPS sensors can detect fixed dangers such as approaching stop signs
through a location database.

5.  Once an impending collision is detected, these systems provide a warning
to the driver.
 When the collision becomes imminent, they take action autonomously
without any driver input (by braking or steering or both).

6.  Collision avoidance by braking is appropriate at low vehicle speeds (e.g.
below 50 km/h (31 mph)), while collision avoidance by steering may be
more appropriate at higher vehicle speeds if lanes are clear.
 Cars with collision avoidance may also be equipped with adaptive cruise
control, using the same forward-looking sensors.

7.  Autonomous: the system acts independently of the driver to avoid or
mitigate the accident.
 Emergency: the system will intervene only in a critical situation.
 Braking: the system tries to avoid the accident by applying the brakes.

8. Features
 Pedestrian detection
 Lane assist
 Blind spot alert
 Hill hold control
 Cornering Brake Control
 Forward Collision Warning
 Cornering brake control
 Evasive Steering Assist Adaptive
Headlights
 Reverse automatic braking

9. Control System of CAS
 An audible warning
 Light braking & seat-belt retraction.
 Strong braking & seat-belt retraction.

10. Warning devices
 Visual head-up displays: warnings are displayed on the windshield in the
driver's field of view.
 Audio/Voice signals: auditory signals appear to be less intrusive on
driving tasks.
