Main parts:

RF section:

Ultrasonic Sensor:2d = v* t

High-performance RISC CPU.

All single cycle instructions except for program branches which are 2 cycle.

Low-power, high-speed CMOS EPROM/EEPROM technology.

Programmable code-protection.

Working of system:

Advantages:

Increased Road Safety.

Reduced strain on engines, thereby increasing

the life of engines.

Reduced fuel consumption.

Reduced maintenance cost for the vehicle

owner.

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.
