Connected vehicles facilitate a wide range of data exchanges, including cooperative driving, accident avoidance, real-time traffic updates, and pedestrian safety. The effectiveness of these safety measures relies heavily on communication range, as timely notifications enable drivers to make prompt decisions. This research addresses the challenge of communication range drops in Non-Line-of-Sight (NLOS) road segments, where the range falls below essential highway safety distances, such as stopping, decision, and passing sight distances. We investigate RSU placement strategies on intercity roads, where direct field visibility scanning is both costly and complex, from a traffic safety perspective. Our study emphasizes the critical role of strategically positioned Roadside Units (RSUs) as multihop relays to extend the range and reliability of Vehicle-to-Vehicle (V2V) systems. Utilizing Digital Elevation Models (DEMs) and visibility analysis through GIS software, we identify NLOS segments and optimize RSU placement to ensure sufficient communication distances for safe traffic system. The findings of this research offer a cost-effective and practical approach to improving safety and operational performance in connected vehicle ecosystems. Our results support advanced traffic safety applications, empowering engineers to predict and mitigate potential risks, thereby contributing to safer, more efficient intercity transportation systems.
