All the components are interfaced precisely so that the accident detection and alert message sending are fully automated, so that the warning time is reduced significantly. 2.2 Flow Chart The Flow Chart of the system is shown in the figure 2. It shows the system is initialized on power ON. When the system is detected to be abnormal, it is confirmed that the accident has occurred. The vibration/acceleration of the vehicle is detected to confirm the cause of the accident. As soon as the accident is detected the buzzer (alarm) is ON. The switch is scanned first; if it is a minor accident then the switch is IJRES Vol. 1, No. 2, July 2012: 49 – 54 IJRES ISSN: 2089-4864 51 ON so that messaging is terminated. If it is a major accident, the switch remains OFF and the message is sent automatically to the rescue team after the location is detected by the GPS.
