协议族在智能交通系统中的应用

The Application of Protocol Family in ITS

信息交换是智能交通中必不可少的部分,信息交换离不开通信协议。随着智能交通系统的发展,信息交换的范围不断扩展,复杂度不断提高,对通信协议的专业化应用以及通信协议的需求也不断提高。协议族是灵活应用已有通信协议,并解决通信协议标准化的合理方法之一,NTCIP是协议族在智能交通中应用的典型例子。本文以NTCIP为例,分析了协议族在智能交通应用的优点,并讨论了协议族在原始交通数据采集中的应用。

Information exchange is indispensable for ITS, and protocol is necessary for information exchange. Along with the development of ITS, the range and complicacy of information exchange are advanced constantly, and its requires for professional application of protocol is improved, too. Protocol family is a reasonable means to use existing protocols flexibly, and realize protocol standardization. NTCIP is a typical example of the application of protocol family in ITS. In this paper, the strong-point of using the protocol family in ITS is analyzed, and the application of protocol family in original traffic data collection is discussed.
