摘　　要：针对目前交通运输中日益增长的高速状态下多媒体通信的需求和构建智能交通系统通信平台的需要,利用移动宽带无线接入技术的特点,并结合智能交通系统的通信需求,探讨了移动宽带无线接入技术在智能交通领域的应用。根据Jake仿真模型和802.20技术标准的相关模型参数,通过计算机仿真对高速运动状态下的通信信道进行了仿真试验。仿真试验中移动信道的误码率得到了较好的控制,其结果证明基于IEEE802.20的移动宽带无线接入技术来搭建智能交通系统通信平台的设想是有效可行的。Concerning the increasing needs of multimedia communication in the situation of high - speed state and the establishment of communicative platform based on intelligent transportation system （ ITS）, by applying the characteristics of mobile broadband wireless access technology, and bearing in mind the communicative needs of ITS, the application of mobile broadband wireless access technology in the field of intelligent transportation is discussed. According to the Jake simulation model and parameters of IEEE802. 20 standards, a simulation experiment for investigating the performance of the channel models with the state of high - speed movement is carried out. The bit error rates of mobile channels are well controlled in the simulation, and the results indicate that it is effective and feasible to establish ITS communication platform through IEEE802. 20 - based mobile broadband wireless access technology.
