In our work we will try to make a comparison between some models of systemic modeling, to draw one or models that can be adapted to the characteristics of the road system from the point of view of road safety. Road safety issues generate significant externalities at the social and economic level, and also at the environmental level, such as accidents involving vehicles carrying dangerous goods. Modeling serves as tools to help understand the problems encountered and subsequently to facilitate decision-making. The systemic approach is a holistic approach that takes into consideration the dynamic and complex aspect of the road system and the effect of the interactions between its different elements on road safety.

Our objective is to choose one or more models for road safety modeling using the systemic approach, based on criteria adapted to the different characteristics of the road system.
