-We are developing an embedded product that helps in prevention of accidents. Our product has concentrated on two aspects to prevent accidents. First, Drowsiness of drivers. Second, Narrow curves on roads of hills. In order to prevent accidents because of these two aspects our product has been proposed. For preventing accidents because of drowsiness we have implemented image processing based on Eye Aspect Ratio (EAR) [1] , it monitors driver and alert them. For preventing at curves we have implemented camera that traps the radius of curve and the vehicle coming opposite. This system also comprises MEMS sensor, GPS, GSM to send message in case of emergency
