In strongly eroded areas a considerable part of rural roads turn into road ravines, which is caused first of all by improper localization (arrangement) of roads in relief. Therefore the arrangement of rural roads in relief and hardening of the surface of dirt roads is one of the most important components in shaping agricultural production space in eroded areas. Proper identification of rural road sections requiring protective measures or, in extreme cases, outlining them a new improves the network of rural roads in an economic way, because it allows an effective allocation of available resources according to protection urgency. The paper is a study of an arrangement of road network in relief and of urgency of their protection with the use of the following indices: IARRR (Indicator for the Arrangement of Rural Roads in Relief) and UHRR (Urgency of Hardening Rural Roads) in the area of Mielnica water course basin. The analysis was performed on digital spatial data with GIS. The results of the research show a big share of road with unfavourable parameters and indicate an urgent need to introduce protective actions on the investigated area. Field research confirmed the results of spatial analysis based on IARRR and UHRR indices.
