This study aims to verify the reliability of Vehicle-to-Everything (V2X) communication systems for improving safety in advanced driving scenarios. Current autonomous driving systems that rely on sensors such as GPS or LiDAR have limitations. Additionally, slight delays when changing lanes can cause traffic congestion. Connected autonomous vehicles can solve this problem by exchanging driving data and controlling movements through 5G New Radio V2X (5G-NR-V2X) communication. In this study, 5GNR- V2X is utilized to facilitate trajectory sharing as well as driving information exchange. Sharing driving trajectories can allow the proactive management of risks due to lane merging and increase maneuvering efficiency. Comparing the proposed method with experiments using LiDAR sensors revealed similar performance, and the former was more cost-effective. This study reveals how connected driving through trajectory sharing can alleviate problems related to road congestion and transportation efficiency.
