Abstract: This paper tests the use of various barrier and corridor effects in cost distance calculation, which often serves as a proxy for accessibility in Land-Use and Land-Cover Change (LUCC) models. The most suitable friction coefficients for barrier effects of slope and water, and corridor effect of roads, are identified by empirical sensitivity analysis. The influence of accessibility on urbanisation, agricultural intensification, and extensification, afforestation, and deforestation in Slovakia is modelled in the present study. The most significant improvement was achieved using the corridor effect of roads for accessibility to the nearest district town, while the barrier of slope significantly improved the effect of accessibility to the nearest commune. Different optimal friction coefficients were identified for different land cover changes; however, only some of them were sensitive to the change of coefficients.
