The main focus in my thesis is given to the position and influence of certain inter-municipal centers in Slovenia. The methodological approach is based on a comparison of data and evaluation of the two sets of indicators that have been developed within the framework of the European project Conspace. The set consists of indicators measuring regional development and assessment of spatial structures and indicators for the identification and measurement of spatial potentials. Based on the hypothesis that the position of inter-municipal center in the urban system is closely connected to the transport accessibility, which remains one of the main factors of development of functional areas despite lacking importance of physical distances, in the paper all the important elements of regional development and spatial development potentials were studied. The values achieved for thirteen intermunicipal centers were evaluated with points, which determines the order of the centers. After merging the obtained results and ranking further evaluation of the situation of inter-municipal centers in terms of transport accessibility was carried out. The results showed that the position of centres in the transport network match the final categories according to 51 indicators: the development of the most dynamic centers have the most favorable access and the most favorable transport position relative to the other compared centers. These centres will (may / probably) be the future bearers of development and strengthening of its role in the region. Center that will be able to exploit the good traffic location and links with other settlements and the region, which will promote an adequate demographic and socio-economic structure, and those who strive and promote healthy natural and rich cultural environment, will be able to successfully compete with other centers of similar rank. This will allow people a higher level of prosperity and become increasingly attractive to live and work.
