The project aims in designing a smart zone-based vehicle speed control along with vehicle anti signal jumping system using RF technology. Now a day's every system is automated in order to face new challenges. In the present days Automated systems have fewer manual operations, flexibility, reliability and accurate. Due to this demand every field prefers automated control systems. Especially in the field of electronics automated systems are giving good performance. The modules in the project are: RF transmitter and receiver modules for establishing wireless communication between vehicle to smart zones and traffic signals. The whole system consists of four sections, specified zone sections like school and hospital which consist of RF transmitter to send the data to vehicle system to intimate its entry to slow the vehicle speed at zone. Anti signal jumping: In this RF transmitter and traffic lights are interfaced to the microcontroller. The system makes use of High-power LEDs as traffic lights. The traffic signal timing changes automatically and delay is provided with the help of microcontroller. The traffic signal runs in an automatic loop and whenever the RED signal falls, the vehicle stops automatically. To conclude, this system is very effective in avoiding the signal jumping and to follow the traffic rules also speed control at smart zones. Another section is with the vehicle (robot) which consists of microcontroller interfaced with DC motors, RF receiver module and LCD display. This Robotic vehicle consist of HC-05 Bluetooth module is uses for controlling the Robotic vehicle by using android mobile application. While moving the vehicle; the RF receiver gets the data relating to entry into slow speed zone and feds this to microcontroller. Microcontroller acts on the vehicle motors to reduce the speed of the vehicle automatically and LCD screen to display the particular zone of vehicles entered.            

The objectives of the project include:

1. Automatic speed control of vehicles when they enter in Speed control Zones like schools, hospitals.
2. Zones names display on LCD screen.
3. Usage of wireless RF communication between Zone system and vehicle system.
4. Automatic vehicle anti signal jumping.
5. Bluetooth controlled robotic vehicle.
