**4.3 Expert poll**

The experts were asked to evaluate the same six main criteria of the highway in two cases; first represents the current highway condition where the second represents a hypothetical condition when the tolling road system (TRS) is applied **Table 3**. In this table, we note the values of each of the main criteria for the efficiency of the road in its current condition in the first column, while experts expect the values to be as shown in the second column if the TRS is applied, moreover the third column shows the lowest acceptable value for each criterion. It is clear from the table that the efficiency of the road in its current condition is low and requires rehabilitation work at all levels, notwithstanding that the application of the TRS will raise the efficiency of the road for all six criteria.
