According to World Health Organization, over a million people die every year due to vehicle accidents. To respond to this situation, the black box concept is used as the first step to solve the problem. In order to overcome this problem, we are trying to implement the concept of "black box" in this paper. This paper describes real-time data collection while driving a vehicle and to check the driving behaviour and a car status, and this data is used to investigate the accident and to investigate the accident. New communication technologies are integrated into modern automobiles, giving the better assistance for the injured people in traffic accidents. Recent studies show how communication capabilities should be supported by artificial intelligence systems capable of automating many decisions to be taken from emergency services. This reduces the security risk for the severity and rescue time of the accident. The accident is indicated by the use of sensors and the location and intensity of the accident can be sent via SMS via GSM. A car black box is a tool used to record engine temperature, interruption, speed, vehicle driving, and information about the accurate location of the vehicle. The outputs of these parameters are displayed in LCD. The data recorder stores the values of all sensors communicated with the controller. Then this information is transmitted via a wireless network. This collected information will be sent to the police server, ambulance via the GSM network. The system considers the most appropriate variables (such as sensors) that represent the severity of the accident. The GPS tracking system in this mobile helps detect vehicle during the accident and enables authorities to expand immediate emergency medical service.
