摘要
智能交通系统是未来交通系统的发展方向,而蜂窝移动通信是智能交通系统主要的无线通信技术。研究无线通信技术满足智能交通的通信需求,是实现智能交通的关键。选取具有代表性的普通高速公路场景,使用蜂窝移动通信网络覆盖,建立移动速度、车流量、用户数、数据包大小和数据包分布的智能交通业务模型。通过仿真分析,验证了3G WCDMA技术和4G LTE技术在智能交通业务中的通信时延、吞吐量承载性能,以期为蜂窝移动通信技术在智能交通中的应用提供理论基础。
ITS （Intelligent Transportation System） is the development direction of the future transportation system, while cellular mobile communication the key wireless communication technology for ITS. The key to realizing the intelligent transportation relies on the grasp of wireless communication technology how to meet the communication needs of intelligent transportation. By selecting the representative common highway scene and using the coverage of cellular mobile communication network, the intelligent traffic service model involving mobile speed~ traffic flow, number of users, packet size and packet distribution is proposed and established. Simulation analysis verifies the communication delay and throughput carrying capacity of 3G WCDMA technology and 4G LTE technologies in intelligent traffic service, expecting to provide certain theoretical basis for the application of cellular mobile communication technology in intelligent transportation.
