摘　　要：车路协同多模通信融合系统在高速公路智能化建设中具有至关重要的作用。本文基于C-V2X及5G技术架构,阐述OBU与RSU在“车-路-云”协同中的实时交互机制,探讨多模通信(DSRC、PC5、Uu等)在高速场景下提升通信带宽、降低时延与强化可靠性的途径,并总结系统在盲点警告、动态路线规划、前撞预警等典型应用中的表现。测试结果表明,多模融合可有效降低复杂路段的丢包率和通信延迟,增强车端与路端协作的稳定性;云控平台则借助边缘计算与大数据分析,实现对道路资源的宏观调控与全局优化。研究认为,车路协同多模通信融合不仅能有效提升行车安全和通行效率,还能为智能网联汽车及无人驾驶技术的规模化应用奠定坚实基础,推动未来交通运输系统朝着更加安全、高效与智能的方向迈进。Vehicle-Road-Cooperation(VRC)multimode communication fusion system plays a crucial role in the intelligent construction of highways.Based on C-V2X and 5G technology architecture,this paper describes the real-time interaction mechanism between OBU and RSU in"vehicle-roadcloud"cooperation,explores the ways to improve communication bandwidth,reduce delay and enhance reliability of multimode communication(DSRC,PC5,Uu,etc.)in high-speed scenarios,and summarizes the performance of the system in typical applications such as blind spot warning,dynamic route planning,forward collision warning,and so on.It also summarizes the performance of the system in typical applications such as blind spot warning,dynamic route planning,and forward collision warning.The test results show that multimode fusion can effectively reduce the packet loss rate and communication delay in complex road sections,and enhance the stability of vehicle-end and road-end collaboration;the cloud control platform realizes the macro-control and global optimization of road resources with the help of edge computing and big data analysis.The study concludes that vehicle-road cooperative multimode communication fusion can not only effectively improve driving safety and traffic efficiency,but also lay a solid foundation for the large-scale application of intelligent networked vehicles and driverless technology,and promote the future transportation system towards a safer,more efficient and intelligent direction.
