摘要
无线通信技术的发展对智能交通系统提出了更高的要求。单纯的Ad Hoc网络或者V2V通信不具有可靠性,很多应用不能实现,而V2R通信对于提高可靠性、安全性及舒适度具有重要意义。V2V通信与V2R通信的相互协作可以实现车辆、人和道路间的信息交换,以方便快捷地获取实时道路交通信息,提高旅途的便利性和舒适度。首先分析了V2R通信的特点,对网络的体系结构进行了介绍,然后重点对V2R通信的连通性进行了研究,最后探究V2R通信技术面临的挑战。
With the tremendous advantages of wireless technologies, it has been put forward higher requirements for intelligent transportation systems（ITS）. Pure Ad Hoc network or V2V communication is not reliable and sufficient for many applications. V2R communication is reliable, safe and comfortable. It can easily and quickly obtain real-time traffic information, because of the cooperation between V2V communication and V2R communication which can achieve the exchange of information between vehicles, drivers, and roads, and improve the convenience and comfort of the trip. Firstly, the characteristics of V2R communication were studied, then the network architecture was introduced. In addition, the connection for V2R communication was analyzed. Finally, the challenges of V2R communication were explored.
