The work presents theoretical bases of an indicator for estimating the arrangement of rural roads in a terrain relief. The indicator bases on the comparison between azimuths of agricultural roads and terrain aspect. The physical interpretation of the indicator is meant as planar angle between the road and the theoretical line ideally perpendicular to slope. Thanks to the physical, non-expert basis of the indicator it is possible to choose arbitrary ranges and thresholds by classifying roads to perpendicular-, diagonal- and along- slope arrangement classes.
