Geomorphology has been defined the study of surface land forms. It is Proceeded to the nature, origin and evolution of landforms, their processes and promotion of their material composition. This knowledge is predominantly a field science, and requires to aim for studying landforms, terrestrial Processes and surface materials. If the « aim » is road policy-making, road-guarding, road-building and safety, it is proceeded to the group of effective processes on roads. All these aims require directly to the geomorphologic studies particularly in mountain areas, and thus provide information which take the basis of stability roads. At present, Geomorphologic information has probably not been applied to the needs of roads stability. There is, however, an increasing recognition by both geomorphologists and by road policymakers that geomorphology has an important role in roads to play alongside other disciplines in the engineering and technical sciences . It is necessary that the road policy-makers be aware of the geomorphologic information can provide and of how it can use in planning formulation of road. The geomorphologists too must be aware of what is the information needs of road builders for road safety. This essay cannot attempt to cover all the various processes, it can merely point to their existence. The main emphasis is on issues that dealt with road policy-making, planning, land stability and safety.
