In this research, all the road of Kermanshah province have been investigated in terms of the existence of defects in the geometric plan. The roads of Kermanshah province have been evaluated in three different categories, including rural roads, approved suburban roads and intra-urban roads. In the field of suburban roads, various geometric conditions such as the condition of horizontal arches along with the conditions of vertical arches and the form of their interference with horizontal arches have been investigated. To carry out this study, more than 12,000 completely new satellite images of the condition of roads in Kermanshah province have been prepared and collected. To analyze satellite images and maps, ArcMap software facilities from ArcGIS collection have been used. After conducting research, about 5,666 geometric defects have been identified in all roads of Kermanshah province. The results of the research show that there is a linear and ascending relationship with high fitting accuracy between the number of geometric defects of rural roads and the number of divisions in this sector, as well as a similar relationship between the length of approved suburban roads and the frequency of geometric defects in them. There is. On the other hand, there is an exponential and upward relationship between the number of geometric defects of the suburban and inner city roads of the province.
