ANALYSIS OF OPERATING COSTS AND SPEED RELATIONSHIP ON SELECTED SECTIONS OF TWO-LANE RURAL HIGHWAYS IN REPUBLIC OF SERBIA
A well-developed, efficient and safe road network is an important factor in the socio-economic development of a country, and in order to achieve this, one of the steps is speed management on road network. In recent years, the concept of optimal speed has been developed, which represents the speed limits optimization in a term of social costs. Therefore, the idea of this paper was to exemine and show the dependence of the operating costs, which covers the direct vehicle operating costs and time travel costs of passangers in vehicles, from different forms of speed on a certain segment of road, by applying the cost model in order to investigate the acceptability of certain speed limits in local conditions in a term of users costs. The data on free speeds and characteristics of road segments, as well as data on real operating speeds and existing speed limits, were used as the basis for the analysis.
