In diploma thesis we analysed several approaches of modelling spatial interaction patterns. We thoroughly tested two common approaches and developed three other methods. The basis for our research was presented by Waldo Tobler (Tobler, 1975). Approaches of modelling and cartographically presenting spatial interactions have been automatized. We used MatLab to develop script tools and perform mathematical computations, while ArcGIS was used to create cartographic materials. In the application of the analysed methods, data on commuters between statistical regions and municipalities of Slovenia for 2011 were used.
