Abstract

Road infrastructure is exposed to several deterioration processes during its use and therefore, its condition has to be monitored throughout its service life. Refurbishment should be planned for structures with inadequate condition. When refurbishment projects are being planned, however, the road managing company needs to take into account also the budget constraint imposed by the financing bodies. The paper presents development of a multi-criteria decision model, to be used in planning and selecting the passes within state road network that intersect a highway section. Criteria on which the model is based are systematically identified and justified, and their relative importance is determined by using the Analytical Hierarchy Process (AHP). The model selects a group of passes spanning over a highway section that yields maximum total utility when the refurbishment projects are executed while keeping the total refurbishment costs below the allocated amount. The applicability of the proposed model is presented for a selected set of passes.
