Main research topics
Gravity Models: inter-country model (Slovenia and Croatia) inter-regional models inter-municipal models
Accessibility modelling accessibility fields coupling accessibility and gravity approach
Functional (vs. Administrative) region modelling functional regions
Inter-regional gravity model (GM&DM) Bogataj M. and S. Drobne (2004): Does the
improvement of roads increase the daily commuting? Numerical analysis of Slovenian interregional flows.In: Zadnik Stirn L. et all (Eds.). Selected decision support models for production and public policy problems, (SDI-SOR series, no. 3). Ljubljana.
Inter-regional (a) migration and (b) commuting were analysed for 12 regions in Slovenia (for period 1991-2002): ... by investing in roads, which would improve the time distance by
20 %, daily commuting (DC) could increase up to 70 % on average;
... by investing in roads, which would improve the time distance by 20 %, gross migration (GM) would increase by 42 % on average.

Inter-municipal commuting flows were analysed to define the gravity model for Slovenia (2002):
Method is applicable for functional urban areas (FUA).

An extended gravity o model was defined to estimate available human resources due to increased daily migrations between regions in Enlarged Europe and expected New Member Country (Croatia).
The model was improved by waiting lines methodology embedded in time spending distance functions.

Accessibility to centres - 1
Drobne S. et all (2005): Will the future motorway network improve the accessibility to administrative centres in Slovenia? In: Zadnik Stirn and S. Drobne (Eds.). The 8th International Symposium on Operational Research in Slovenia, Nova Gorica, Slovenia, September 28-30, 2005. SOR '05 proceedings. Ljubljana.
A two-stage raster-based GIS approach for evaluation of continuous accessibility fields was proposed.
Method is applicable for urban areas. The improvement of accessibility to administrative
centres due to new highways and motorways were studied for period 2005-2013.

The 10th International Symposium on Operational Research in Slovenia, Nova Gorica, Slovenia, September 23-25, 2009. SOR '09 proceedings. Ljubljana.
Method for delimitation of functional regions by using data for inter-municipal daily commuting of working population was suggested. Method is applicable for functional urban areas
(FUA). The method was tested to analyze how so
defined functional regions fit to proposed provinces (administrative regions) in Slovenia:
The proposal for six administrative regions in Slovenia is “stronger” than the model of eight ones – there are not eight, but nine functional regions in Slovenia.
