# Real-Time Security Health and Privacy Monitoring for Saudi Highways Using Cutting-Edge Technologies
## 2 Literature Review  
This section presents an overview of the existing work undertaken in real-time security, health, and privacy monitoring for highways using CET with a particular focus on KSA highways. Paper [23] proposes a smart traffic monitoring system based on unmanned aerial vehicles (UAVs) and 5G technologies. This traffic monitoring system addresses the shortcomings of the SAHER system already used in Saudi Arabia. It has been noted that the number of accidents and fatalities can be reduced by overcoming the SAHER system's existing restrictions and loopholes. According to the predicted findings, when such breaches are eliminated, the number of accidents per year drops to 299,317, resulting in 4868 deaths and 33,199 injuries in the first year. In the next five years, deaths and injuries reduce to 3745 and 16,600, respectively. According to paper [16], the major issue for high data rate real-time video transmission is current 4G wireless data performance. However, with the advent of 5G technology, this problem may be alleviated due to the higher data rates available with 5G. Using 5G-enabled vehicular cloud networks (VCNs) to deliver accident-occurring recordings to the appropriate authorities in real-time, roadside accident live video reporting services might become a reality. The suggested three-way handshake protocol can prevent attackers from accessing private/sensitive data/information acquired by built-in video sensors in cars. Paper [24] provides a thorough examination of contemporary technologies (IoT, 5G, and Cloud) and their implications for improving an intelligent transportation system's ability to monitor and regulate traffic congestion. The article [25] explores the security and privacy issues in the transportation system and the vehicular IoT environment in an SDN-enabled 5G vehicular ad hoc network (VANET). The vehicular IoT services, such as real-time cloud-based video reports and trust management on vehicular communications, are supported by a blockchain-based security architecture. It further discusses the SDN-enabled 5G-VANET architecture and the blockchain-based framework's scheduling methods in detail. The numerical simulation \begin{table}

With the convergence of VANETs, software-defined networks, 5G, and mobile edge computing technologies, article [26] proposes a unique four-tier architecture for urban traffic management. In a more dispersed and dynamic manner, the suggested architecture enables better communication and faster response performance. In the case of a quick accident rescue, the rescue time can be considerably reduced. Vehicle geolocation, data pre-fetching, traffic signal control, and traffic prediction are among the key technologies addressed. The suggested innovative architecture has significant promise for reducing traffic congestion and enhancing urban traffic management efficiency. In paper [27], an intelligent traffic management system (ITMS) was presented to prioritize emergency vehicles by merging the concepts of VANET and IoT to improve ambulance flow in metropolitan areas. It demonstrates a way to detect and prevent traffic signal hacking, which is a fairly prevalent problem nowadays.
