Abstract
With the rapid development of intelligent transportation systems and connected vehicle technologies, intelligent connected vehicles have become a crucial component of future smart mobility. As a core supporting technology, V2X (Vehicle-to-Everything) communication provides key technical means to enhance traffic efficiency, ensure driving safety, and achieve autonomous driving. This study focuses on the V2X communication technology for intelligent connected vehicles and its applications, aiming to explore the key technical fr amework, application scenarios, and implementation paths of V2X communication while analyzing the challenges and optimization strategies in practical deployment. By integrating theoretical analysis with experimental validation, this research first systematically reviews the V2X communication technology system, including a performance comparison between the two mainstream technical routes: DSRC (Dedicated Short-Range Communication) and C-V2X (Cellular Vehicle-to-Everything). Secondly, a simulation platform is constructed based on real-world road environments to evaluate data transmission latency, reliability, and coverage range under different communication scenarios. Finally, combined with typical application scenarios such as cooperative driving and traffic signal priority control, a multi-source information fusion-based intelligent decision-making algorithm is proposed. The results indicate that C-V2X technology demonstrates superior stability and scalability in complex environments, and the proposed algorithm significantly improves the system's response speed and decision accuracy. The primary innovation of this study lies in proposing an optimized communication solution for intelligent connected vehicles adaptable to dynamic traffic environments, which has been experimentally validated to effectively enhance traffic safety and efficiency, providing significant reference for the construction of future intelligent transportation systems.
