Figure 1 — the AHP diagram of main criteria and sub criteria of interurban cost modeling
e First level Modeling: after preparing a The relative preference of one part to another part cost
comparative table of criteria and sub criteria of model is resulted from the quantitative result of F in
the model and collecting the cost model experts above-mentioned formula. In other word that part is
points of view about the first level, two formulas selected after cost model analysis, which has the
were achieved: highest value in all studied parts of routes network.
Also the part with the shortest length is selected so the
After the paired comparison of criteria in four lengths of the route and F function have reverse
different statuses in first level this general formula for relationship with each other. At last this general
cost model is achieved: : formula is offered as the general cost model:

In this formula f is the primary cost model of the roads The important point in these kinds of modeling is that
excluding the length criterion, n is the quantity of the coefficients in the formula are normalized it means
effective criteria in cost model of the roads and Xi that the aggregate of these coefficients is equal to 1.
shows the effective criteria to cost model and K is a The four different phenomena of the general cost
constant coefficient determined by experts of cost model (formula 3) are mentioned bellow: Evy ©
