In recent decades, the rapid advancement of technology has significantly impacted road infrastructure development, leading to the emergence of what is known as "smart roads." These roads rely on Intelligent Transportation Systems (ITS), which are a combination of integrated technologies including sensors, cameras, smart traffic signals, and wireless communication networks. The main goal of ITS is to improve transportation efficiency, reduce accidents, and enhance traffic safety.<br /><br />Traffic safety remains one of the most pressing challenges facing governments worldwide. According to reports from the World Health Organization, road accidents result in more than 1.3 million deaths annually (World Health Organization, 2023). ITS technologies have proven effective in reducing accident rates by providing real-time information to drivers, guiding them through interactive systems, and monitoring unsafe behaviors with instant alerts to relevant authorities.<br /><br />One of the key ITS applications in improving road safety is the Advanced Traffic Management Systems (ATMS), which continuously monitor and analyze traffic flow, adjusting traffic lights to reduce congestion and prevent collisions. Early warning systems, such as forward collision alerts or lane departure warnings, also play a major role in avoiding accidents, especially on highways.<br /><br />Moreover, vehicle-to-infrastructure (V2I) and vehicle-to-vehicle (V2V) communication technologies contribute to building a cooperative transportation network. These systems allow cars to exchange data with each other and with road infrastructure to avoid real-time collisions. These technologies are also fundamental for integrating autonomous vehicles into a safer and more efficient transportation ecosystem.<br /><br />It is worth noting that the success of these systems depends on the availability of robust digital infrastructure, clear regulatory frameworks, and collaboration among public and private sectors. Additionally, raising public awareness of the importance of these technologies plays a crucial role in their adoption and proper usage.<br /><br />In conclusion, ITS technologies are a cornerstone for building safer and more efficient roads and are essential tools for achieving sustainable development goals in the transportation sector. With the continued advancement of artificial intelligence and the Internet of Things, the scope of ITS applications is expected to expand, further enhancing road safety and improving the user experience.
