Nowadays road accidents are very common in our society and these accidents will cause injuries to the common people. Sometimes people will die in the road accidents. We can’t predict when and how accident will occur. Today accidents are happening even for the standing vehicle by the other moving vehicle. We developed the Micro controller based Bus backside accident alert system to avoid such collision between vehicles. By using this system, we can avoid the accident between a vehicle and the other vehicle which is running/standing in the backside of the vehicle.

Transmitting section and receiving section are the two major sections of this project. Transmitting section has a ultrasonic sensor and it is used for the transmission of signal. Similarly Receiving section has another ultrasonic sensor and it is used to receive the signal.

Those signals are recorded by the micro controller and then it will detect any variation or changes in the normal operation.  Then micro controller transfers the message to the buzzer and LCD display. The buzzer will alert the driver. Thus by using this system we can avoid the accident within few micro seconds. In upcoming days, this project is very useful for the public.
