Accidents occur so often and with such uncertainty these days. Accidents produce the most damage, serious injuries, and sometimes even fatalities. The driver's failure to apply the brake in a timely manner is the primary cause of these collisions. Preventive measures, such as improving visibility, putting headlights on cars, windshield wipers, tire traction, etc., were put into place to reduce the chance of an accident. We are now in the process of actively preventing collisions while providing the highest level of safety for drivers and even pedestrians. Thus, in this study, we try to provide a novel automated vehicle accident avoidance system. The purpose of this project is to develop new technology that will enable drivers to use sensors to stop their automobiles automatically when they come across obstacles rather than manually applying the brake pedal. The primary objective of this study is to develop a sensor-based embedded system that can assist drivers in avoiding crashes on the road in order to save lives and prevent financial loss.
