The aim of this study is to design safe driving system which is constantly being worked on every year in the world to reduce traffic accidents that cause economic and social loss in very large sizes. The developed safe driving system works on mobile phones that are not part of other secure driving systems. By this way, regardless of the technological equipment of the vehicle, old or new all means of vehicles via mobile phones have become safe driving possibilities. The second goal of this study is to integrate knowledge of mechanical engineering with knowledge of software engineering so that these two professions will work together in future projects.
