# Real-Time Security Health and Privacy Monitoring for Saudi Highways Using Cutting-Edge Technologies
## 4 Results and Evaluation
### Proposed Passenger Safety Mechanism  
Now we discuss the working of the proposed model where all the registered vehicles on the highway are equipped with front-back security cameras which fetch real-time passenger data and send it to the cloud through 5G. The image-processing scheme will analyze the vehicle images and raise alarm in case of an accident. This alarm will intimate TAs to take the required action. TAs will monitor real-time data of the vehicles for providing timely legal and medical help to the passengers traveling on the road. Below are the three possibilities of road crash incident. Case 1: Vehicle is crashed but security camera is working and there is no other vehicle on the road. \begin{table}
\begin{tabular}{l l l l} \hline \hline
**Parameters** & **Weightage** & **Weight Value** & **Weight Description** \\ \hline \multirow{2}{*}{Early reporting} & \multirow{2}{*}{Partial} & \multirow{2}{*}{0.5} & The passerby will be either \\  & & & & \\  & & & & trusted authorities or not \\  & & & & \\  & & & & \\  & & & & \\  & & & & \\  & & & & \\  & & & & \\  & & & & \\  & & & & \\  & & & & \\  & & & & \\  & & & & \\  & & & & \\  & & & & \\  & & & & \\  & & & & \\  & & & & \\ \end{tabular}

Table 5: Weighted sum of evaluation parameters in Case 2 of the existing system. In Case 1, if a vehicle is involved in an accident but the security camera is operational as shown in Figure 5a. TAs will be informed of the incident based on the data obtained from the security camera installed in the victim's vehicle. By sharing the footage of the situations, TAs will alert the local legal and medical authorities for assistance. When the local first-aid authorities are informed of the incident's specifics, they will take appropriate action. The overall performance of the system will be evaluated based on the six parameter values as shown in Table 6 and Equation (5). \[Prob(S)=\frac{1}{6}(1+1+1+1+1)=\frac{6}{6}=1 \tag{5}\]  
In this instance, the chances of receiving timely assistance will be high, and the only reason for the delay might be the distance between the victim and the aiding authorities. Case 2: Vehicle is badly crashed and IoT-enabled front-back cameras stop working but there are other vehicles on the road. Figure 5: (a) Case 1 (proposed model), (b) Case 2 (proposed model), (c) Case 3 (proposed model). In this case, when a vehicle collides and the security camera stop working but there are other vehicles on the road as shown in Figure 4(b), the chances of receiving timely medical and legal assistance are increased. The reason for increased assistance is that not only will the passing-by vehicle notify local legal authorities, but TAs will also learn about the incident from the alarm sent by image-processing scheme after analyzing the data of other vehicles on the road. Thus the overall performance of the system will be evaluated based on the six parameter values as shown in Table 7 and Equation (6). Substituting the weight values of Table 7 in Equation (2), we get the probability of success as shown in Equation (6):  
\[Prob(S)=\frac{1}{6}(1+1+1+1+1+1)=\frac{6}{6}=1 \tag{6}\]
