摘要
第五代移动通信技术(简称5G)以其具有的更高峰值速率、更大传输容量、更低传输时延以及更大终端密度等优势,正成为物联网技术变革升级的重要推动力。智能交通路口参与对象众多、运行状况复杂,是道路交通物联化的具体体现。该文基于5G通信技术,搭建人、车、路三者实时互联、信息共享的智能路口管控系统,根据用户终端提供的数量、位置、速度、目的地等信息,结合大数据、云计算技术,开发出流量调节、危险预警、路线引导及安全提醒等功能,有效提高了道路交通资源的利用效率,降低了交通事故的发生概率。基于5G技术的智能交通路口管控中心,未来必将对无人驾驶、高效救援、智慧城市、通行优化等应用场景产生巨大的支持作用。
The fifth generation mobile communication technology(5G for short)is becoming an important driving force for the transformation and upgrading of Internet of Things technology because of its advantages such as higher peak rate,greater transmission capacity,lower transmission delay and greater terminal density.Intelligent traffic intersection has many participants and complex operation conditions,which is the concrete embodiment of road traffic IoT.Based on 5G communication technology,this paper builds an intelligent intersection management and control system of real-time interconnection and information sharing among people,vehicles and roads.According to the quantity,location,speed,destination and other information provided by the user terminal,combined with big data and cloud computing technology,the functions of flow regulation,danger warning,route guidance and safety reminder are developed,which effectively improves the utilization of road traffic resources.Efficiency reduces the probability of traffic accidents.The intelligent traffic intersection management and control center based on 5G technology will play an important role in supporting unmanned driving,efficient rescue,smart city,traffic optimization and other application scenarios in the future.
