The project aims in designing an intelligent system which helps in avoiding accidents by alerting and speed controlling, if vehicle to vehicle has less gap.In day-to-day life road accidents goes on increasing due to varies reasons. Some road accidents may cause due to chasing between two vehicles. We avoid these kinds of accidents by providing some precautionary methods using ultrasonic sensors.

The project aims in designing an intelligent system which helps in avoiding accidents by alerting and speed controlling, if vehicle to vehicle has less gap.   In day-to-day life road accidents goes on increasing due to varies reasons. Some road accidents may cause due to chasing between two vehicles. We avoid these kinds of accidents by providing some precautionary methods using ultrasonic sensors.  Ultrasonic sensors generate high frequency sound waves and evaluate the echo which is received back by the sensor. These sensors calculate the time intervals between sending the signal and receiving the echo to determine the distance to an object. If the distance of the vehicle is too small then this vehicle is automatically control the speed of the vehicle which avoids the potential risk of the accident. The main controlling device of the system is a Microcontroller. Ultrasonic sensor, buzzer and DC motors along with l293d motor driver are interfaced to Microcontroller. The microcontroller gives an alarm if distance is less than predefined limit from obstacle. If the sensor detect obstacle this data is fed as input to the micro control and microcontroller stop the vehicle ignition automatically. Here relay works as a switch to on/off the ignition. To perform the intelligent task, Microcontroller is programmed using embedded ‘C’ language.
