In highly populated countries, people lose their lives because of accidents and poor emergency facilities every day. These lives could have been saved if medical facilities are provided at the right time. This thesis implies a system which is a solution to this drawback, when a vehicle meets with an accident immediately, accelerometer module detects the signal, and it is sent to the Arduino microcontroller programmed by C programming language. Arduino sends an alert message through the GSM module including the location to the police station or a rescue team. So the police can immediately trace the location through the GPS modem after receiving the information. LCD is used to display location message from GPS module. The system is simulated and practically designed by the use of required hardware components and the results are satisfied with the expectation.
