The maintenance of public infrastructure is one of the most significant parts of public goods
management. Road maintenance includes planning and investing in the road network to provide safety,
maximize traffic flow and reduce environmental costs. Road maintenance is divided into many groups,
however, this thesis focuses on the procedure of summer and winter road maintenance as a way of public
concession works.
This thesis aims to find the optimal number and locations of road maintenance facilities along with the
areas they maintain. The thesis focuses on the road network by the administration of the Slovenian
Infrastructure Agency, Ministry of Infrastructure. The transportation and maintenance facilities'
operating costs define optimum criteria. Analyses helped find efficient scenarios using GIS technologies
such as location-allocation and others.
The first part of this work presents the formal structures of the road management system in Slovenia and
the rule of important participants. Similar road systems worldwide and Slovenian motorway network
management and maintenance systems are compared and described.
The second part focuses on the road maintenance activities system, its valuation, and the parameters
which are used in calculations. Disadvantages of the existing system are presented with the basis for
new analysis. The analyses are followed by financial evaluations for each option and the comment about
merging smaller units into larger ones. In conclusion, the results of this thesis are presented together
with the advantages and disadvantages of different types of infrastructure maintenance.
