Abstract: Now a dayís probably accidents of commercial vehicles on highway has increased. 80% of accidents happen because of Driverís unconsciousness and confusion. The solution for this accident prevention is quit complex and costly; hence consumer class of commercial vehicle is not capable to afford intelligent security system. Ultrasonic sensor based stationary radar system is an affordable solution for this problem which consist accident prevention and detection capability. The ultrasonic sensor & Accelerometer plays a vital role for preventing accidents and detecting the location of the same if required. Our main aim is to design a real time security system which is capable to detect stationary object for 180 degree front phase considering the dimensions of wheel track.
