Vehicle-road collaboration technology application and performance comparison and intelligent fusion simulation analysis

交通网络的持续扩展和交通流的不断增加使得高速公路协同管控极为重要,通过科学的协同管控策略来有效提升交通效率和行车安全性。在对车路协同技术分析的基础之上,构建了车路协同架构,并对高速公路场景不同通信协议的性能进行了对比,指出C-V2X技术的丢包率明显低于IEEE 802.11p技术。结合行车方向,避免反向车辆干扰,提出了高速公路资源调度算法,并通过仿真验证了高速公路资源调度算法能够有效避免反向车辆通信干扰,降低丢包率。

The continuous expansion of the transportation network and the continuous increase of traffic flow make the collaborative management and control of expressways extremely important,and the traffic efficiency and driving safety can be effectively improved through scientific collaborative management and control strategies.Based on the analysis of vehicle-road cooperation technology,the architecture of vehicle-road cooperation was constructed,and the performance of different communication protocols in highway scene was compared,and it was found out that the packet loss rate of C-V2X technology was significantly lower than that of IEEE 802.11p technology.Combined with the direction of driving to avoid the interference of the reverse vehicle,a highway resource scheduling algorithm was proposed,and the simulation verification of the highway resource scheduling algorithm could effectively avoid the communication interference of the reverse vehicle and reduce the packet loss rate.
