**6. Compare alternatives using AHP**

A comparison with the present road management system is undertaken in order to suggest the deployment of the Toll Road System TRS. That is, the AHP software is used to apply the values of the primary and secondary criteria for both cases that were collected by specialist academics. The program can address the best situation and yields the best alternative **Figure 4**.

*Synthesis priorities for the alternatives.*

The alternatives are grouped together in a single cluster, here we have two alternatives for highway management, one of them represent the current management system and other for the toll road system TRS.

**Figure 5** shows the numerical values of each of these main criteria and their impact on the quality of the road. It is noted that safety take the largest importance with value of 33.2%, while the road conditions and the geometric design are equal at 19.4%, as well as the services with the cost of 10.7% while the environmental impact is less importance with 6.3%. The amount of inconsistency should be less than 0.1, which is achieved here by a comfortable amount.

After entering all the values and conducting the treatments to find the best alternative, the result was to prefer the toll road system TRS at a rate of 75%. This is an expected and logical result as has how this system could provide all the required standards for a comfortable and safe road operation. As can be seen in **Figure 6**, the differential values are shown in the middle (Normal) column.
