# Real-Time Security Health and Privacy Monitoring for Saudi Highways Using Cutting-Edge Technologies
## 2 Literature Review
Using hacked and non-hacked traffic lights, the distance between intersections and emergency cars was calculated to accomplish the desired travel time of emergency vehicles with the least delay. The suggested approach distinguishes between emergency signals of varying priority and prevents hostile actors from issuing misleading alerts. The experiments demonstrate that the proposed system outperformed others in terms of time restrictions, allowing emergency assistance to be provided in the quickest period feasible. The suggested method reduces the time it takes for accident victims to receive medical help and transfer essential patients and medicines. Table 2 provides the comparative analysis of existing traffic management solutions. The results of Table 2 and some other studies [28; 29; 30; 31; 32; 33] show that the existing solutions mainly focused on intelligent transportation to reduce the accident ratio, traffic congestion, and the passing of emergency vehicles in cities. To the best of our knowledge, there has not been any research on passenger safety on Saudi highways, especially providing medical and legal facilities in case of a post-crash incident. To fill this gap, this paper proposes a model RTSHPMP based on IoT, cloud, and 5G to facilitate passengers traveling on Saudi highways. RTSHPMP aims to provide timely health and legal facilities to traveler in the case of an accident. The details of the RTSHPMP are given in Section 3. Before going into details of the proposed methodology, we provide a preliminary investigation in the next subsection. _Preliminary Investigations_  
Before proceeding towards the proposed methodology, there is a need to understand the problems faced by the conventional approach to passenger safety in order to know the current state of the art and the need for the proposed model. This will also help in the analysis and comparison of the proposed methodology. \begin{table}

Table 2: Comparative analysis of existing solutions. RTAs are a common problem worldwide. However, they are one of the leading causes of injury and death in KSA. The ministry of health's statistics [34] show the fatality rate linked with roadside accidents, as illustrated in Figure 1a-d. The statistics of Figure 1a-d show that RTAs are one of the most common problems that need to be given attention. Providing timely help to a passenger in the case of an accident can help reduce fatalities. Although SMOT has taken various steps in the last two decades to remove these accidents, still one of the major reasons for fatalities is the lack of timely help in post-crash events, especially on Saudi highways which are considered the world's largest long roads. Most of the highways are surrounded by dessert and unpopulated areas due to the geography of the kingdom. In such a situation, timely medical and legal help to the passengers on these highways can save human life and assets.
