10. Working of System

11. WORKING
• The system is mainly based on micro controller
technology
• The micro controller analyses the transmitted data and
takes appropriate decisions related to speed limit and
control requirements
• The speed limit of the vehicle will be transmitted using
RF transmitter to the approaching vehicles
• This calculated speed from the RPM meter is given to the
next input pin of the comparator
• If the speed of the vehicle is greater than the speed limit
the controller will reduce the speed of the vehicle to the
limit by using PWM characteristic of the micro controller.

12. Advantages
• Increased Road Safety.
• Reduced strain on engines, thereby increasing the life
of engines.
• Reduced fuel consumption.
• Reduced maintenance cost for the vehicle owner.
• Avoids Accidents.

13. CONCLUSION
• This can be easily implemented near different populated areas.
• The power of the proposed system lies in its flexibility and
capability of development with little hardware changes such as
changing the speed limits and speed control methods using the
software of the base station in negligible amount of time.
• This is based on microcontroller technology for collecting data
related to speed and transmitting it through a transceiver to a base
station that analyzes the transmitted data and takes appropriate
decisions related to speed limit and control requirements.
