As we know now a day’s cases of kidnapping of school students are increases rapidly in metro cities. To overcome this problem or issue we design this system called smart school bus for children transportation in this system we are going to use raspberry pi as a processor. When the student entered in bus the RFID card which is given to the student was read by the RFID reader and the message to the parents. The alcohol sensor is mounted in driver’s cabin. When the driver is drunk the alcohol sensor will sense it and send the message to school authority and they will take an action on it. We also provide the accident indicator. In which we use the vibration sensor to sense the major vibration. The GPS/GSM module helps to communicate with parents and school authority.
