摘要
智能交通系统和城市交通指挥中心联网技术可以应对由车辆数量激增带来的交通环境及安全方面的挑战。车载自组网(Vehicular Ad Hoc Network,VANET,是一种特殊的移动自组网(Mobile Ad Hoc Networks,MANET)在未来智能交通系统中将占有重要地位。主要针对VANET的无线通信相关技术进行了研究,介绍了其现状与体系结构,对其特点与挑战、标准协议、通信技术等进行了概述,探讨了VANET的未来发展前景。
Intelligent transport systems and network technologies in urban traffic command centers can meet the challenges on road traffic environment and safety caused by the soaring car ownership. As a special kind of mobile ad hoc network （MANET）,vehicular ad hoc network （VANET）,will play an important role in intelligent transport system in the future.The paper studied on VANET wireless communicationrelated technology and briefly introduced its development status and system architecture. An overview of its characteristics, challenges, standards and communication technology is given, which leads to the discussion of the future development prospect of VANET.
