Abstract: Most of the accidents on highways as well as on roads can lead to social as well as economic impacts. For minor accidents it is not necessary to give much more attention because passengers themselves take care. Whereas other accidents in which airbags are deployed requires immediate attention. Accident Detection by an Intelligent System (ADIS) is a smart system which informs to the emergency contacts through text messages when there is a change in acceleration, rotation and force which is detected by different sensors. These sensors are connected to the central system of the car. The idea behind this system is to inform authorities after collision immediately to avoid congestion and allows passengers to be hospitalized quickly. The system consists of Fuzzy logic as a decision support which decides accident is happened or not.
