摘　　要：为了能够通过车辆之间的相互通信来提高旅客的安全性、减少交通拥堵等,基于IEEE 802.11p/1609标准,提出了路车互联网的概念,并对路车互联网中RSU(路边单元)和OBU(车载单元)之间的通信进行了仿真和分析。仿真结果表明,RSU和OBU之间的通信比较稳定,丢包率也较低,显示在车载环境下IEEE 802.11p/1609协议较好的性能,这也为未来国家智能交通系统的普及和产业化发展迈进了一步。To improve passenger safety,reduce traffic congestion,this paper proposed road-car network which was able to communicate with each other through the vehicles based on IEEE 802.11p/1609,and simulated and analysed the communication between the OBU and RSU.As a result,the communication between RSU and OBU seemed relatively stable,low packet loss rate.This result shows good performance under the standard of IEEE 802.11p/1609 which is also a step forward for the future popularity and the industrialization of the national intelligent transportation system（ITS）.
