Abstract

Due to the high rate of Traffic accident and death toll in Iran, recently the case has altered into a major national hitch.  Through System Dynamics point of view and examining significant factors like the yearly death toll of vehicle accidents in Iran, the importance of the case gets more vivid. Generally the case beholds various dimensions (Multi Dimensional Case) and special complexities. The study applies “System Dynamics” approach. Having defined the Dynamic problem, considering the “literature review”, and exploring the interviews four groups of major factors were scrutinized as effective and significant. Concentrating on the four main factors, the “Casual Loop Model” was developed. The system was divided to several subsystems (several main sections). Afterward “Casual Loop diagram” was presented for each subsystem. Finally the three proposed strategic policies were introduced to enhance the behavior of main system variables such as set-up “In-charge organization” or leading organization.
