Road transport network is facing a wide range of natural and human disasters, because of geographical extent and functional diversity. In addition to direct damage to road transport networks, accidents can cause indirect damage to road network users and even entire community. Present research is an attempt for assessing potential areas of road accidents in highways of East Azerbaijan province. In this regard, four main criteria (climate, environmental, topographic and road factors) and fourteen sub-criteria were used. The weights of each criterion and their sub-criteria were computed using ANP model. In doing so, the final map of proposed sites for road accidents was prepared by integrating them with standard layers. The results of this study revealed that road safety criterion has the most importance in road accidents and the sub-criterion of the crash is also of paramount importance. Furthermore, the segment of Koshksaray-Marand was the most dangerous area and segment of Jolfa-Norduz was the least risky area in terms of the probability of occurrence of road accidents in highways of East Azerbaijan province.

The increase in motor vehicles and the increasing use of cars in the last half century have had adverse effects. These include the number of accidents and the amount of financial and fatal accidents per year. Various factors may affect road accidents, some of which are inevitable and some can be controlled. Among these factors, we can mention the problems of geometric design of the course, environmental conditions and human factors. Accordingly, in this research, identifying identifying road accidental points in the transit roads of East Azerbaijan province using ANP and BWM models. The BWM model as a new model is one of the multi-criteria decision-making models that Taking into account the best and worst criteria, weighing criteria and sub criteria and It can be used in various spatial modeling. In this regard, four main criteria (Climate factors, Environmental factors, Topographic factors, Road factors) and fourteen sub-criteria were used. In order to weight and evaluate the importance of criteria and sub-criteria, two models of BWM and ANP have been used and After calculating the weight of criteria and sub-criteria and integrating them with the standard layers, the final map of the potential road accident occurrences is based on both models. Based on the results, the criterion of climatic factors in both models is of the highest importance in road accidents and the criterion of environmental factors is least important in this regard. Below are the criteria used in both models, Under the rainfall criterion, the most important and the lowest criterion of the river have the least importance in the occurrence of road accidents. The most dangerous route in terms of location in both the Keshkeri-Marand route and Jolfa-Nordoz route is the least dangerous route among the transit routes of the East-Azerbaijan province. The results of the comparison of the two models show that the BWM model with a Consistency Ratio of 0.075 was better than the ANP model with a Consistency Ratio of 0.09. Also, the matching of the results from the two models used with ground control points indicates the greater accuracy and efficiency of the BWM model of the ANP model
