Abstract

In this study, to prevent pavement destruction and enhance the quality level, restoration and improvement of roads are carried out. The operational costs include fuel consumption, travel time, accidents, tires’ wear and tear and so on. In the economic evaluation, reduction of such costs due to the improvement of the quality level of roads is considered as the project’s benefits. In this paper, the benefits gained through roads’ improvement (i.e. costs reduction) are compared with another one and then the priority of each one in the economic evaluation is determined using the results found from the B/C and Net Present Value (NPV) methods. For this purpose, the required model has been prepared using software written with the Visual Basic Programming Language and its output has been presented as the results of a case study carried out in Fasa-Zahedshahr main road. The evaluation of each element in the economic viability of roads’ improvement projects is one of the specific features of the model presented in this paper.
