**4. Data analysis and results**

This section deals with the surveys that were conducted with road users, road specialists and experts, and the results obtained from processing this data in the SPSS program.

#### **4.1 The drivers' questionnaire**

A questionnaire was distributed to road users and drivers of various types of vehicles to gauge their feelings about the current state of the road and their willingness to accept the implementation of the toll road system. The sample consisted of 94 users, whose responses are shown in **Table 1**. The table shows that 77% refuse to pay the fees for using the road in its current condition, while 87% agree to pay the fees if maintenance is done for the road and the provision of services and safety factors.

Also, 63% of the respondents indicated that they would increase the fare for passengers if the fees were collected from them to use the road. Finally, 94% of them expressed their desire to limit the speed on the expressway and impose fines on violators.

**Figure 2** depicts the order of services sought by road users in order to optimize efficiency.

#### **4.2 Questionnaire for specialized academics**

The questionnaire items included a group of carefully designed questions that aim at determining and describing the quality and operational performance of the road based on a set of main criteria from which a set of sub criteria were derived **Table 2**. From the table the highest importance was given to safety by 9 degrees, and the least importance in determining the efficiency of the road was given to the

environment by 6 degrees, while road conditions and geometric design were of great importance by 8 degrees, followed by services and cost by 7 degrees. In the same way, the importance and importance of the secondary criteria can be read, as the evaluation was done on a scale from 1 to the least important and 9 to the highest importance.
