One of the basic steps in the process of road safety management is defining the causes of accidents depending on the geometry and environmental conditions. The purpose of this study is to provide a new method for consideration of an accident due to environmental and geometrical conditions of the route and preparation of these factors in geographical information system, which takes accidents into consideration according to the interaction of their components. Multi-criterion decision-making method gives advantages which allow the causes of accidents to be ranked and prioritized appropriately in terms of seismic event. In this study, in order to provide criteria and its sub criteria, GIS and the formed database in this space was used and then this information was weighted in the analytical hierarchy technique so that the main causes of accidents in Qeshm loft axis be recognized. The results showed that the criteria of the distance from the intersection, the radius of the arc, and road width respectively with weights of 0.279, 0.255, and 0.140 are the most important accident factors according to the geometric conditions and environment axis.
