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: 
n 
; N F = s. K, X, 
f > (K; X;) = L

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 ©
