In recent years, research on emergency traffic evacuation has increased intensively. Detection of the optimal discharge route is one of the most important parts of crisis management due to the large number of effective measures. In this research, we have used the Analytical Hierarchy Process, taking into account three criteria, road capacity, population density, and structural parameters, and several sub-criteria, and taking into account the actual weight of the criteria for traffic emergency evacuation routing . The method presented in this research is not limited to these three criteria, and can be done with other criteria, based on the conditions of the case study area. The study area in this research is the region of Sabzemeydan, a region in Zanjan city (capital of Zanjan province, northwest of Iran), which has been studied based on the above criteria. The proposed route for emergency traffic evacuation in the studied area, using the proposed method in this research, has all the effective parameters in traffic evacuation, in times of crisis, and is the most optimal route for simultaneous examination based on their real impact.
